I have an old laptop running as a server (It runs Ubuntu Natty).
When I SSH into the box, it often takes a long time to log on, if it's been a while since last time I logged on. I suspect the reason to be that the SSH daemon is put to sleep somehow, and has to be woken before I can log on. Can anyone explain why this happens?
Besides SSHD the server runs Transmission Daemon and two Dropbox instances.
I have appended "UseDNS no" to /etc/ssh/sshd_config.
The machine is running a desktop kernel, because I use it as a backup desktop machine as well. Would it help to change it to a server kernel, or would that disable my desktop? I have read that there might be issues with nVidia drivers when running a server kernel, but don't know if this applies on Natty.
