SuseLinux10 ssh connections are slow

If I try to connect via ssh, it takes a few seconds to respond. And if I go away from my putty window for to an internet window or something for a few 20 or 30 seconds even, it will frequently take 3 to 6 seconds to start responding again. This is highly annoying.

I imagine this is a priority process priority issue. Anyone know how I can fix it?

Try disabling reverse DNS lookups and see if that helps.

Uncomment "UseDNS" in sshd_config and set it to no.

Ok, the second line is how to do what you told me to do in the first line.

I will try this later, thanks. I hope it works because I am quite certain someone is going to mention it to me if I don't fix it before Monday.

It's really bad. Anytime I go away from the putty window and come back, there is a 3 to 5 second lag before it starts responding again.

Nice! It definitely fixed the problem for the login lag. I'll have to use the system a bit before I know if it fixed the other problem, but I have my hopes up. Thanks!

EDIT:

Ok, this definitely fixed it! Thanks.

d'oh

Spoke too soon. Rather it seemed to have fixed it but definitely did not fix it. I think the login prompt appears quickly now, but if I leave the ssh window for more than 10 or 20 seconds, it takes a bunch of seconds to start responding again.
