Machines

Role	IP	Details
Host (Illiac)	192.168.1.119	Physical machine, user sits here
Linux guest	192.168.1.164	Claude Code runs here, user: harry
Windows guest	192.168.1.102	hostname: ops, user: bradmin, pass: tyc921202

Both guests accessed via noVNC from host. Clipboard doesn't work well.

How to Manage Windows Remotely

sshpass -p 'tyc921202' ssh -o StrictHostKeyChecking=no bradmin@192.168.1.102 "command"

Default shell is PowerShell — use ; not && to chain commands
sshd was manually registered: sc.exe create sshd binPath= "C:\Windows\System32\OpenSSH\sshd.exe" start= auto
Windows has SSH key auth back to Linux (bradmin@ops key in harry's authorized_keys)

Proxy Chain (Internet Access)

Windows browser
  → HTTP proxy (Privoxy 192.168.1.164:8119)
    → SOCKS5 proxy (autossh 127.0.0.1:8118, service: poly-tunnel)
      → poly-proxy remote server
        → internet

autossh tunnel: systemd service poly-tunnel, -D 8118, enabled on boot
Privoxy: listens on 127.0.0.1:8119 and 192.168.1.164:8119, forwards via forward-socks5t to 127.0.0.1:8118, enabled on boot
Windows proxy: registry HKCU:\...\Internet Settings ProxyServer=192.168.1.164:8119, persists across reboot
Linux curl: use -x socks5h://127.0.0.1:8118

Key Gotchas

Privoxy must use forward-socks5t (not forward-socks5) for HTTPS to work
Chrome must be fully closed before relaunching with --proxy-server flags
Don't kill all SSH processes on Windows — it kills the user's SSH session too
Windows was on a domain whose DC is gone — domain-dependent services may fail
NTP reconfigured to ntp.aliyun.com (old domain DC gone)
