My ISP's SSH server (Debian 2.0) logs me out after 35 minutes of inactivity, when connected with PuTTY (Windows XP). This is a big problem when I utilize the server for port-forwarding. The final messages displayed in the terminal:
This terminal has been idle 30 minutes. If it remains idle for 5 more minutes it will be logged out by the system. Logged out by the system.
PuTTY options that do not help:
- Sending of null packets to keep session active. Seconds between keepalives (0 to turn off): 30
- [x] Enable TCP keepalives (SO_KEEPALIVE option)
Any idea how to avoid the auto-log-out? Should I try another SSH client?
