The solution is simple:


ClientAliveInterval <time in seconds>
ClientAliveCountMax <default is 3>

to your /etc/ssh/sshd_config

I set mine to 30 seconds and leave the count at 3, but thats because
I'm tunneling over ssl which has a 300 second timeout.

However, I think a good question is why is your putty session timing
out to stock standard sshd?
