Session Log: 2026-03-19

Session Summary

Major workstation setup and Dataforth infrastructure session. Set up new CachyOS Linux install on ASUS laptop (acg-guru-5070), fixed multiple system issues, wiped old Windows drive for /home, reset ESXi licenses, and diagnosed/fixed Dataforth FreePBX phone system.

Work Completed

1. Tailscale Validation & Fix

• Issue 1: --accept-routes was false - peers advertising routes but not accepted
• Fix: sudo tailscale set --accept-routes
• Issue 2: systemd-resolved and NetworkManager misconfigured for MagicDNS
• Fix: Created /etc/NetworkManager/conf.d/dns.conf with dns=systemd-resolved, symlinked /etc/resolv.conf to /run/systemd/resolve/stub-resolv.conf, restarted both services and tailscaled
• Result: All health warnings cleared, MagicDNS working

2. Google Chrome Installation

• Installed via paru -S --noconfirm google-chrome (AUR)
• Version: 146.0.7680.153

3. Display Brightness Fix

• Issue: Brightness at 100% per KDE but visually dim
• Root cause: intel_backlight was at 100/496 (~20%), KDE was reading nvidia_0 (100/100)
• Fix: Set intel_backlight to max: echo 496 > /sys/class/backlight/intel_backlight/brightness
• Hotkey fix: Created /etc/udev/rules.d/backlight.rules to hide nvidia_0 so KDE only controls intel_backlight
• Ran sudo chmod 000 /sys/class/backlight/nvidia_0 for immediate effect
• Restarted plasma-powerdevil

4. Secondary Drive Setup as /home

• Drive: nvme1n1 (954GB SK Hynix) - old Windows BitLocker drive
• Steps:
  • Wiped with wipefs -a
  • Created GPT partition table with single ext4 partition (label: "home")
  • UUID: 4143f922-455f-4154-8f87-6df123548916
  • Copied existing /home via rsync -aAXv /home/ /mnt/
  • Updated /etc/fstab - replaced btrfs @home subvolume entry with new ext4 mount
  • Original btrfs @home subvolume still exists on OS drive as backup
• Requires reboot to activate

5. ESXi License Resets (Dataforth)

• 192.168.0.122: Evaluation expired, reset via SSH
  • Created sysadmin user (Paper123!@#) for SSH access
  • Reset: rm -r /etc/vmware/license.cfg && cp /etc/vmware/.#license.cfg /etc/vmware/license.cfg
  • Restarted vpxa and hostd
  • New expiration: 2026-05-18
• 192.168.0.124: Same procedure via root user
  • SSH enabled from web UI
  • New expiration: 2026-05-18

6. FreePBX/Asterisk Phone System Fix (Dataforth)

• PBX: 192.168.100.2 (pbx.intranet.dataforth.com)
• OS: Sangoma FreePBX Distro 17 / Debian 12
• VM: On ESXi 192.168.0.122, VM ID 9, SAN-D1-15k datastore

Issues Found & Fixed:

1. Asterisk was not running - started with fwconsole start
2. fwconsole reload was failing with Undefined array key "trunk_name" in PJSip.class.php line 504
   • Root cause: getAllTrunks() SQL query (LEFT OUTER JOIN with IS NULL) returns extension data mixed with trunk data. Extensions lack trunk_name key.
   • Also: Orphaned trunk ID 2 (FirstDigital_SIP) in pjsip table with no matching entry in trunks table
   • Fix: Patched line 504: $tn = $trunk['trunk_name'] ?? null; if ($tn === null) { continue; }
   • Backup at PJSip.class.php.bak
   • Deleted orphaned trunk: DELETE FROM pjsip WHERE id='2'
3. Asterisk logging was broken - no full log file configured since Jan 27
   • Fix: Added full => notice,warning,error,verbose,dtmf,fax to /etc/asterisk/logger_logfiles_custom.conf
   • Logger now writing to /var/log/asterisk/full
4. Call transfer event listener was intermittently failing with "Asterisk is not connected" errors in AMI

PBX Status After Fix:

• Asterisk running, PJSIP trunk (FirstDigital) connected
• 30+ extensions registered
• fwconsole reload succeeds
• Full logging restored
• SIP trunk: FirstDigital at 66.7.123.215 (match: 66.7.123.0/24)
• Outbound CID: 5207411404

7. Packages Installed

• nano (for visudo)
• sshpass (for automated SSH)
• expect (for ESXi/PBX SSH sessions)
• google-chrome (AUR)

8. Sudo Configuration

• Added guru ALL=(ALL) NOPASSWD: ALL to sudoers via EDITOR=nano visudo

• D2TESTNAS: 192.168.0.0/24
• Missing: 192.168.100.0/24 (VLAN100/PBX) - requires Dataforth WiFi or adding route to pfSense-2

Files Modified

• /etc/NetworkManager/conf.d/dns.conf (created)

Pending/Incomplete Tasks

1. Reboot required for /home mount to switch to new ext4 drive
2. PBX call testing - users should verify DIDs, transfers, and general calling work
3. PBX VLAN100 routing - not accessible via Tailscale, need to add 192.168.100.0/24 to pfSense-2's advertised routes
4. ESXi license reminder - both hosts expire 2026-05-18 (60 days)
5. PBX auto-start - verify Asterisk starts automatically on VM boot to prevent future outages
6. fail2ban logs - 70MB/day suggests external SIP scanning; may want to review firewall rules
7. Windows reinstall script - user asked about a PowerShell script for reinstalling Claude config after Windows reset; not found in repo, may need to be created
8. PJSip.class.php patch - will be overwritten on FreePBX module update; monitor for upstream fix
