New architecture: two LDAP nodes with multi-master (MMR) replication, two MTA+proxy nodes, a single mailbox server, a single archive server, a dedicated LDAP/license-daemon node, and two HAProxy+keepalived nodes providing a shared virtual IP as a load balancer in front of the proxy pair (so either proxy can fail without users noticing). Covers building MMR replication between the two LDAP nodes (each pointing to the other as its replication master), the archiving setup (a dedicated, mail-only Class of Service with an auto-created per-user archive account that silently BCCs a copy of every inbound/outbound mail, restored via export from the archive account and import back into the user's mailbox when needed), and the live migration itself -- moving each of the ~400-500 mailboxes one at a time via `zmmboxmove` with the sync happening in the background so users see no disruption. Cutover was done by repointing the HA virtual IP's DNS to the new setup and updating the Barracuda relay IP configuration for external in/out mail; the old single server was then decommissioned via `zmprov deleteServer` once every account was confirmed moved off it. Only client-specific customization requested afterward was their own logo on the Zimbra login</ins>/<ins style="font-weight: bold; text-decoration: none;">webmail interface.</ins></div></td></tr> </table> Sat, 25 Jul 2026 02:53:30 GMT Admin https://wiki.tetrain.com/index.php?title=Category_talk:BHUTAN https://wiki.tetrain.com/index.php?title=Category:INFOSYS_DGRAM_ELK&diff=3729&oldid=3635 https://wiki.tetrain.com/index.php?title=Category:INFOSYS_DGRAM_ELK&diff=3729&oldid=3635 <p>Add YouTube video summaries and fix broken video embeds (HTML5video -&gt; EmbedVideo)</p> <table style="background-color: #fff; color: #202122;" data-mw="interface"> <col class="diff-marker" /> <col class="diff-content" /> <col class="diff-marker" /> <col class="diff-content" /> <tr class="diff-title" lang="en"> <td colspan="2" style="background-color: #fff; color: #202122; text-align: center;">← Older revision</td> <td colspan="2" style="background-color: #fff; color: #202122; text-align: center;">Revision as of 02:53, 25 July 2026</td> </tr><tr><td colspan="2" class="diff-lineno" id="mw-diff-left-l3">Line 3:</td> <td colspan="2" class="diff-lineno">Line 3:</td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>==Training on INFOSYS DGRAM ELK  KT Part 1.

Each cluster has active-active MTA pairs, multi-master LDAP replication (MMR, not the default single-master replica type), an active-passive PCS-clustered mailbox pair, plus its own archive and log server, fronted by HAProxy for high availability. Internal mail between the two clusters routes MTA-to-MTA based on domain-level split routing rules; if a user isn't found on one cluster the mail retries against the other before bouncing. External-facing access goes through a separate single-URL server running an Nginx + Python/Flask app that looks up which cluster a given user's mailbox lives on and redirects the login accordingly (mobile/IMAP/POP/ActiveSync instead go directly through per-cluster virtual IPs, since the single-URL server only handles web/443). Also covers why a dedicated OpenLDAP lookup server was built in front of the Barracuda spam gateway -- Barracuda can't hold two entries for the same domain, so this lookup server independently mirrors valid usernames from both Zimbra clusters so Barracuda can bounce mail for nonexistent users before it ever reaches the mail servers.

Architecture, top to bottom: a public IP/domain NATed to a private IP shared by two DMZ-facing reverse-proxy servers (Proxy 1 primary, Proxy 2 secondary) using keepalived for a floating/virtual IP, so both proxies can receive traffic simultaneously based on load, each configured to prefer its local app server (App1) and fail over to App2 only if App1 becomes unavailable for a defined window; two application servers (App1 primary, App2 secondary) behind the proxies, where App1's attached disk (holding `/data` and `/backup`) is shared out to App2 via NFS -- note this is a direct NFS export from App1 itself, not a separate third-party NFS appliance; and two database servers (DB1 master, DB2 slave) with one-way replication, where App1 always writes to DB1 and manual promotion of DB2 to master is required if DB1 fails. External backups are handled by a separate team using a Commvault backup agent. The session then walks through the actual proxy-server build: installing/upgrading Apache, a redirect vhost that forces all HTTP requests to HTTPS, and a separate reverse-proxy vhost implementing the App1-primary/App2-fallback routing, with the firewall restricted to ports 80/443/56 and keepalived installed only on Proxy 1 in production. On the app server side: mounting the dedicated data disk, storing actual application data under `/data` and symlinking it into the Apache document root (with root ownership, SGID, and group-based permissions so the Apache user can read</ins>/<ins style="font-weight: bold; text-decoration: none;">write without owning the files), editing the app's DB-connection config, installing PHP and its required packages (noting Ubuntu bundles PHP with Apache, requiring an Apache restart to apply config), and installing phpMyAdmin from a downloaded tarball into a defined path with its own vhost, read-only S3-backed file storage for downloadable assets, and appropriate permissions.</ins></div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div> </div></td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><br></td><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><br></td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>==Training on Deshwal Project Part 2.

Walks through the staging deployment procedure: VPN into the private staging server IP, run a pre-existing sync script to keep required files intact, then use Jenkins (a free-style project pulling from a specific Git branch/repo via stored credentials, deploying into the document root) to trigger a build -- explicitly warning never to click </ins>"<ins style="font-weight: bold; text-decoration: none;">Build Now</ins>" <ins style="font-weight: bold; text-decoration: none;">or </ins>"<ins style="font-weight: bold; text-decoration: none;">Delete Now</ins>" <ins style="font-weight: bold; text-decoration: none;">except when specifically instructed, since it deploys whatever code state currently exists, clean or not -- and finally verify the deployed site loads correctly via its URL/credentials. Production deployment mirrors staging but with different server IPs, plus an extra step: SSH to the F1 production server to run a script that syncs a specific set of files from staging into production, since some config isn't carried automatically. Covers a one-time full config backup already taken to Tetra's own S3 bucket (with the exact command used and date logged) as a safety net, and a separate, ongoing CommVault-driven backup regime run by the client's own backup team: proxy servers get a one-time backup only (rarely change), app servers get a weekly snapshot (Sunday 1am, 30-day retention, 4 copies always available), and the DB servers get both incremental backups (daily Monday-Saturday, 7-day rolling retention) and full weekly backups (Sunday 1am, 14-day retention, 2 copies), including filesystem and database data in both. Lists CommVault-side contacts to reach for backup mode changes or restores, and the client-side point of contact for general project queries.

Also opens up the Jenkins job's actual build configuration for a deeper explanation: it pulls from the master branch of the Deshwal Git repo using stored credentials, whichever code developers have most recently pushed; the build step is a shell script that first fixes file/folder ownership and permissions, `rsync`s the pulled code into the Apache document root while excluding an </ins>"<ins style="font-weight: bold; text-decoration: none;">intact</ins>" <ins style="font-weight: bold; text-decoration: none;">folder (config/data files that must survive each deployment and are instead separately synced back in from a preserved backup location), and runs the `rsync`/`chmod`/`chown` operations with `sudo` because the Jenkins service account needs elevated rights for those specific operations -</ins>- <ins style="font-weight: bold; text-decoration: none;">with a matching `sudoers` entry granting Jenkins passwordless access to exactly those three commands.</ins></div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div> </div></td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><br></td><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><br></td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><br></td><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><br></td></tr> <tr><td colspan="2" class="diff-lineno" id="mw-diff-left-l73">Line 73:</td> <td colspan="2" class="diff-lineno">Line 82:</td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>==Training on Oxypc CICD Deployment KT DESHWAL.

Explains the GitHub webhook integration that makes deployment fully automatic: a developer push to GitHub fires a webhook that Jenkins listens for, which kicks off the entire pipeline (checkout -&gt; validate -&gt; backup -&gt; deploy -</ins>&gt; <ins style="font-weight: bold; text-decoration: none;">notify) without manual triggering -- noting the presenter doesn't have direct access</ins>/<ins style="font-weight: bold; text-decoration: none;">credentials to the GitHub webhook config itself (owned by the client's dev team) but can describe the flow. Closes by briefly showing a `sudoers` entry added for the Jenkins user to allow the specific commands the pipeline needs without a password prompt.</ins></div></td></tr> </table> Sat, 25 Jul 2026 02:53:19 GMT Admin https://wiki.tetrain.com/index.php?title=Category_talk:DESHWAL https://wiki.tetrain.com/index.php?title=Category:BEETEL&diff=3720&oldid=3673 https://wiki.tetrain.com/index.php?title=Category:BEETEL&diff=3720&oldid=3673 <p>Add YouTube video summaries and fix broken video embeds (HTML5video -&gt; EmbedVideo)</p> <table style="background-color: #fff; color: #202122;" data-mw="interface"> <col class="diff-marker" /> <col class="diff-content" /> <col class="diff-marker" /> <col class="diff-content" /> <tr class="diff-title" lang="en"> <td colspan="2" style="background-color: #fff; color: #202122; text-align: center;">← Older revision</td> <td colspan="2" style="background-color: #fff; color: #202122; text-align: center;">Revision as of 02:53, 25 July 2026</td> </tr><tr><td colspan="2" class="diff-lineno" id="mw-diff-left-l4">Line 4:</td> <td colspan="2" class="diff-lineno">Line 4:</td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>==Training session on Beetel Project 19 Dec 2023 - Tetra Support Staff - Manish Singh==</div></td><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>==Training session on Beetel Project 19 Dec 2023 - Tetra Support Staff - Manish Singh==</div></td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><br></td><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><br></td></tr> <tr><td class="diff-marker" data-marker="−"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #ffe49c; vertical-align: top; white-space: pre-wrap;"><div><del style="font-weight: bold; text-decoration: none;">&lt;HTML5video type="</del>youtube<del style="font-weight: bold; text-decoration: none;">" width="</del>640" <del style="font-weight: bold; text-decoration: none;">height=</del>"<del style="font-weight: bold; text-decoration: none;">480</del>" <del style="font-weight: bold; text-decoration: none;">autoplay=</del>"<del style="font-weight: bold; text-decoration: none;">false"&gt;1Clvbt1Vin4&lt;</del>/<del style="font-weight: bold; text-decoration: none;">HTML5video&gt;</del></div></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins style="font-weight: bold; text-decoration: none;">{{#ev:</ins>youtube<ins style="font-weight: bold; text-decoration: none;">|1Clvbt1Vin4|</ins>640<ins style="font-weight: bold; text-decoration: none;">}}</ins></div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div> </div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins style="font-weight: bold; text-decoration: none;">'''Video summary:''' </ins>"<ins style="font-weight: bold; text-decoration: none;">Beetel Project</ins>" <ins style="font-weight: bold; text-decoration: none;">-- a Hindi-language KT session covering support/troubleshooting for Beetel's Java-based website (running on JBoss + Apache httpd + PostgreSQL), originally hosted on a cloud provider and later migrated by Tetra to Beetel's own in-house servers (Tetra retains VPN-based access for support, though day-to-day control sits with Beetel). Establishes the standard troubleshooting sequence for a </ins>"<ins style="font-weight: bold; text-decoration: none;">site is down</ins>" <ins style="font-weight: bold; text-decoration: none;">ticket: first check whether the site's front page loads (it may still render by default even if login is broken, so logging in with the help-desk test credentials is required to confirm the app is actually healthy), then check the three core services -- httpd, JBoss, and PostgreSQL -- restarting whichever is down (Apache/Postgres restart cleanly via `systemctl`, but JBoss additionally needs a specific follow-up command/script to fully bring the application back up after a restart). Covers the backup setup in detail: a daily 2am PostgreSQL database backup and a monthly (1st-of-month, 12am) JBoss/application backup, both driven by cron-scheduled scripts stored under root, landing first in a local backup directory (retained 7 days for DB, 4 backups for JBoss, older files auto-pruned by a custom cleanup script) and then rsynced out to a mounted remote Windows backup server share for longer-term retention. Explains how to verify backups are actually landing (checking file dates/sizes under the local and mounted remote backup paths) and flags that very old files sometimes accumulate on the remote mount and may need manual cleanup since retention there isn't automatic. Also references a rough personal migration notes file (IPs, /etc</ins>/<ins style="font-weight: bold; text-decoration: none;">hosts entries, DB setup steps from the original migration) as background context, explicitly noting it's not needed for day-to-day support -- the three-service-check-plus-backup-monitoring routine is what actually matters for tickets.</ins></div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122;

Access to the environment is via a VPN client requiring a one-time password emailed on connect, plus a separate web UI for direct VM console access. Given the heavy audio gaps in this recording, finer procedural detail (exact commands, snapshot restore steps) could not be reliably captured -- this summary reflects only what came through clearly.</ins></div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122;

Snapshots for all VMs on BM1 are stored on BM2 (and vice versa was considered during migration planning but rejected in favor of just cross-host snapshot storage, not full replication) on a monthly schedule. Explains the access model in detail: Tetra's VPN IP is allow-listed only on the SDNet server itself, so direct SSH/PuTTY access is limited to that one box; reaching any other VM (Windows servers, etc.) requires a separate Beetel-provided VPN client that routes into a Cockpit-based web GUI, through which individual VMs can be opened/managed -- this is also how Windows-specific issues (e.g. copy-paste not working, permission fixes) get handled, since Cockpit is the only path to those machines.

To eliminate the single-point-of-failure risk of that old hardware, the presenter P2V'd it: took a full disk image of the physical server (a QCOW2 image, visible mounted via NFS in the hypervisor's storage) and imported/ran it as a VM inside a Proxmox VE cluster (referred to as </ins>"<ins style="font-weight: bold; text-decoration: none;">PRX</ins>"<ins style="font-weight: bold; text-decoration: none;">), with the original physical server kept powered off and untouched as a fallback (since both share the same IP, only one can be online at a time -- if a rebuild is ever needed, the physical box can simply be powered back on). Walks through the actual recovery/access procedure step by step: log into the Proxmox web UI (root credentials provided), select and start the Oracle VM from the console if it isn't already running, then reach the application's web frontend on a specific port found via `netstat -antp` on the guest (in this case landing on port 9000, one of several Java service ports tried) using the client's own application login.

Incoming mail flow is: KSMG (a secure mail gateway that applies spam/allow-block rules and can bounce mail) -&gt; IMSVA (Trend Micro InterScan Messaging Security Virtual Appliance, doing further per-IP/domain/account filtering) -&gt; a Postfix daemon pair -&gt; the MTA -&gt; the destination mailbox; every user also has a separate archive (AR) account that a linked archive server populates for all in/outbound mail. Hyderabad runs four physical servers -- two paired mailbox/MTA/proxy servers (PCS cluster + fencing, so the standby takes over automatically if the active one fails), a shared pair of NAS storage boxes (primary/secondary) behind them, a dedicated AR server, and an internal mail gateway serving ~18-20 internal domains (with manual internet-relay as a fallback if that gateway fails). Kota and JTC mirror this setup but use DRBD replication instead of PCS/NAS, which the presenter flags as the single most important thing to monitor: DRBD sync must be checked daily, since if the primary fails while sync is only partially complete (e.g. 60%), the un-synced portion of data is permanently lost on failover. All outbound internet mail from Kota/JTC users must route through the Hyderabad MTA hub -- intra-site mail doesn't need this. Mailbox sizing (Class of Service) is tied to employee designation/grade (e.g. 2GB/7GB/12GB/18GB tiers), and user creation is scripted to auto-provision the matching archive account and notify designated stakeholders. Common support scenarios covered: 90-day mandatory password rotation and reset requests, a 30MB outbound attachment size cap, password-protected PDFs being blocked/bounced on delivery (unprotected PDFs pass), mailbox quota checks for </ins>"<ins style="font-weight: bold; text-decoration: none;">can't send mail</ins>" <ins style="font-weight: bold; text-decoration: none;">tickets, and a protected </ins>"<ins style="font-weight: bold; text-decoration: none;">public circular</ins>" <ins style="font-weight: bold; text-decoration: none;">dynamic distribution-list folder that only one admin account can modify.</ins></div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div> </div></td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><br></td><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><br></td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>==Training on NFC Project KT PART 2.

Covers the two Zimbra webmail clients NFC users may be on (Classic and Modern) and why it matters to ask which one a caller is using before troubleshooting; per-site public-circular distribution lists (Hyderabad, Kota, JTC); a two-tier attachment policy enforced via mail transport groups -- </ins>"<ins style="font-weight: bold; text-decoration: none;">Group One Transport</ins>" <ins style="font-weight: bold; text-decoration: none;">permits attachments, </ins>"<ins style="font-weight: bold; text-decoration: none;">Group Two Transport</ins>" <ins style="font-weight: bold; text-decoration: none;">(assigned by officer designation) does not -- plus separate sender restrictions that limit some users to internal-only mail. Describes the KVM-virtualized server layout per site (each physical/base machine hosts a paired mailbox/MTA/LDAP/proxy set) and the failover model: connectivity or load issues trigger automatic cluster failover to the secondary node, but a mailbox-specific problem requires a manual cluster shift; console access via the KVM host's URL is the fallback when SSH/PuTTY access fails, and if even the console doesn't respond the VM must be power-cycled. Notes an important operating constraint: NFC (a central government client) does not permit any remote login access to their environment -- support is done by walking NFC staff through fixes verbally on calls rather than connecting directly. Covers day-to-day troubleshooting patterns: slow mail delivery caused by a full mailbox quota; users' archive mount getting incorrectly pointed at another site's archive server (checked/fixed via `zmmailbox` commands to unmount and remount correctly); the full outside-to-inside mail path (KSMG -&gt; IMSVA -&gt; Postfix -&gt; MTA -</ins>&gt; <ins style="font-weight: bold; text-decoration: none;">mailbox) and where to check first when external mail isn't arriving, including manually releasing genuine mail that IMSVA quarantines as unscanned</ins>/<ins style="font-weight: bold; text-decoration: none;">spam (safe to release, and released mail doesn't get re-quarantined); and daily DRBD replication-status checks required only at Kota and JTC (which use active-passive DRBD replication), since Hyderabad's mailbox setup is active-active and doesn't need this check.</ins></div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div> </div></td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><br></td><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><br></td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>==Training on NFC Project KT PART 3.

Confirms that NFC-to-NFC mail (e.g. Kota to JTC) stays entirely on the internal gateway and never touches the internet path. Walks through the two ways new mailboxes get created: an automated bash script that interactively prompts for username, mail ID, display name, storage quota tier (2/6/12/18/32 GB), and site (Hyderabad/Kota/JTC), then auto-creates and mounts the matching archive (AR) account for Kota/JTC users -- versus manual creation through the Zimbra admin console (referred to as </ins>"<ins style="font-weight: bold; text-decoration: none;">GI</ins>"<ins style="font-weight: bold; text-decoration: none;">), which requires the AR account to be created and mounted by hand afterward. Goes deep on the DRBD replication risk at Kota/JTC: it's active-passive, so if the primary disk fails while the secondary is only partially synced (e.g. 50%), only that synced portion survives -- recovering from a </ins>"<ins style="font-weight: bold; text-decoration: none;">StandAlone</ins>" <ins style="font-weight: bold; text-decoration: none;">(out-of-sync) state requires manually disconnecting and reconnecting DRBD to force a resync, with no automatic reverse-sync. By contrast Hyderabad's mailbox cluster is active-active, storing identical data on both nodes in parallel, so this failure mode doesn't apply there. Also covers: checking HAProxy status per site (`systemctl status proxy`) as a first troubleshooting step; SSL certificate deployment on the proxy servers, where three separate cert files are combined into a single `bundle.pem`, the previous bundle is backed up (renamed `.old`) before the new one is deployed, Hyderabad's proxy is the single point where certs are uploaded/renewed (Let's Encrypt for one flow, a purchased commercial cert handed off by the vendor for another) and then synced out to Kota/JTC's proxies, and that RocketChat on this environment uses the same certificate; that antivirus/patch management for the gateway is handled entirely by the vendor, out of Tetra's support scope; domain-based mail routing through the internal gateway versus the internet path, including updating Postfix's `postmap` after adding/renaming a routed domain; and how to rename a user's mailbox/alias (demonstrated with a promoted senior officer's account) so mail to both the old and new address keeps reaching them via an alias pointed at the renamed account.

Explains the manual PCS cluster failover procedure step by step: check cluster status to see which node (mailbox1/mailbox2) is currently live and confirm both nodes are online, then standby the active node and un-standby the other to force a controlled switch -- only done in response to a real connectivity/overload issue, not routinely. Covers the DA-domain bypass procedure: if NFC's local email gateway can't reach a particular DA (government) domain, editing Postfix's transport config to comment out that domain's local-gateway routing so mail for it goes via the internet path (IMSVA) instead. Reiterates the with-attachment/without-attachment/internal-only sender group model and the DRBD up-to-date-disk check that only applies at JTC/Kota (not Hyderabad, which is active</ins>-<ins style="font-weight: bold; text-decoration: none;">active NAS replication). Adds new maintenance detail: daily ClamAV signature updates (main.cvd, bytecode.cvd, daily.cvd) pushed via script to the MTA antivirus scanning layer across all three sites, and confirms SSL certificates and RocketChat are both maintained without downtime as part of routine operations.

Also covers CRPF's specific requirement around their 429 physical offices: accounts are provisioned with an office-suffixed internal domain and restricted so a user can only mail within their own office's user group, while an email alias masks that internal office-specific address so the outside-facing address a correspondent sees never reveals which office the user belongs to.</ins></div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div> </div></td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><br></td><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><br></td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>==Training on CRPF KT Session Part 1.

Covers OS installation basics for these servers (minimal RHEL-family install, local-only root credentials, no external access), and explains cross-environment mail delivery via split-domain routing: since the same domain exists on both sides, a mail from an Open Source user to a Network Edition user (or vice versa) is routed by checking whether the recipient exists locally; if not found on either side after being relayed back and forth up to three times, it bounces back to the sender. Also notes structural differences from the other session's description: mailbox servers here are standalone (no HA clustering) and each environment has its own log server rather than a shared archive server. Full installation documentation was noted as being covered in a following session.</ins></div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div> </div></td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><br></td><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><br></td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>==Training on CRPF KT Session Part 2.

The network is split into a DMZ zone (a 192.168.1.x segment, holding the WAF and external HAProxy) and an MZ/internal zone (a 192.168.2.x segment, holding the internal HAProxy, the four LAMP web servers -- each serving a different client domain in the Traditional environment -- and the database servers), with NAT rules on the firewall exposing the private DMZ IPs to the internet.

A separate problem is also covered: because uploaded files (PDFs etc.) land only on whichever LAMP server actually handled the request, and the paired servers aren't otherwise replicated, a failover could leave the secondary server missing files the primary had received. This was solved with a shared NFS server -- both paired LAMP servers mount the same NFS-backed directory (e.g. the upload folder), so either server can read files regardless of which one originally wrote them. The eSign environment mirrors this exact design but with a smaller footprint (essentially one web server instead of four).</ins></div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div> </div></td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><br></td><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><br></td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><br></td><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><br></td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>==Training on YOUSECURE Project KT PART 2.

Demonstrates using `tail` on the HAProxy log (under `/var/log`) to watch real incoming requests in real time and read the log lines to identify which named backend and which specific server (`srv1`/`srv2`) each request was routed to, confirming the `balance first` failover behavior live -- including what the log looks like when the primary is down and traffic is on the secondary.

Also revisits the NFS setup in more detail: a `/data` partition with per-service subdirectories (video, KYC, etc.) is exported from the NFS server and mounted onto the equivalent local content directory (e.g. mounting over `/home`) on both paired LAMP servers per site, so uploaded content is visible to whichever server is active.

The presenter notes the full YouSecure setup took roughly 4-5 months to build.</ins></div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div> </div></td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><br></td><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><br></td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><br></td><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><br></td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>==Training on YOUSECURE (Signxca) DR related training.

Opens with the conceptual architecture: the primary datacenter (DC) runs both the eSign and Traditional environments across four oVirt/RHV hosts backed by a shared, partitioned storage array, while the DR site is a smaller, half-capacity mirror (fewer hosts, its own storage) connected to the DC via one-way storage-to-storage replication that gets reversed once a DR drill or real failover ends. A key design point is an L2 network extension between DC and DR, meaning VMs can come up at the DR site with the exact same IPs they had at the DC -- during a real DR event, the DC side is shut down, replication is paused, and the full environment (normally ~200-300 VMs, though DR is provisioned at reduced capacity) is expected to boot at DR unchanged. The session then moves into hands-on DR-drill execution: navigating the oVirt </ins>"<ins style="font-weight: bold; text-decoration: none;">Disaster Recovery</ins>" <ins style="font-weight: bold; text-decoration: none;">role, generating the DR configuration file (`dr.conf`) from a template using the manager's API credentials, hostnames, and CA certificate copied from the currently-active site, correcting auto-generated/commented-out fields for the secondary (DR) site, verifying host DNS/hosts-file entries and reachability between manager and target hosts, and applying the resulting Ansible playbook-driven failover. Also covers checking storage/data-domain visibility from the DR-side manager UI and using the `admin@internal` oVirt account for command-line/API operations. The recording includes real troubleshooting back-and-forth (access</ins>/<ins style="font-weight: bold; text-decoration: none;">OTP issues, a mid-session interruption) rather than a clean scripted demo, consistent with an authentic live training call.</ins></div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div> </div></td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><br></td><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><br></td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><br></td><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><br></td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>==Training on YOUSECURE (Signxca)-Ovirt-Partial-DR-DRIL related training.

Architecture: an rsyslog relay server receives logs from all devices on ports 514 (TCP) and 8514 (UDP) and forwards them to a 2-node Elasticsearch cluster (both nodes configured as master, for redundancy) via Logstash, with a custom Logstash filter/pipeline tagging entries by hostname and program name. Covers building alert rules from specific Windows Event IDs (account disabled/enabled/deleted, privilege/security-group escalation, failed logins, password resets, audit log clears) and equivalent Linux alerts (sudo escalation, failed su attempts, anti-brute-force config changes), plus McAfee (ePO) event alerts and ELK's own internal health alerts (cluster health, disk/CPU usage, shard/thread-pool sizing).

Architecture: an rsyslog relay server receives logs from all devices on ports 514 (TCP) and 8514 (UDP) and forwards them to a 2-node Elasticsearch cluster (both nodes configured as master, for redundancy) via Logstash, with a custom Logstash filter/pipeline tagging entries by hostname and program name. Covers building alert rules from specific Windows Event IDs (account disabled/enabled/deleted, privilege/security-group escalation, failed logins, password resets, audit log clears) and equivalent Linux alerts (sudo escalation, failed su attempts, anti-brute-force config changes), plus McAfee (ePO) event alerts and ELK's own internal health alerts (cluster health, disk/CPU usage, shard/thread-pool sizing).

The presenter frames the exercise explicitly as a teaching moment -- stressing that everyone on the team should understand how to build a Zimbra server end-to-end and the different available migration methods, since this knowledge underlies most support and migration work.

Before failing over, checks that DRBD (application data) and MySQL master-slave replication are fully synced between the two nodes. Failover itself is done by putting the currently-active node into standby (`pcs node standby`), which cleanly stops its services in order (Apache, cron, NPCD, Nagios) while the other node starts the same services and takes over the virtual IP -- verified both from the Nagios admin panel and from the backend PCS</ins>/<ins style="font-weight: bold; text-decoration: none;">fencing status.
