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?
