Slow SSH
Is SSH being slow? Are you running Ubuntu (8.04 at the time of this writing)? I've found the following solution fixes slow SSH and Telnet logins. Specifically, the symptom is an annoying ~10 second delay between attempting to log into a remote terminal, and when it prompts you for a password. If this is happening to you, do the following (to the remote machine):
sudo nano /etc/hosts
Then, just add a line with the IP address and host name of the machine you are logging in from. Apparently, the remote machine is trying to do a DNS lookup, or something, and timing out. If it already has your machine in its list of hosts, you can get in instantly. I've found a few other folks discussing this in the forums, but none of their suggestions worked for me.
Happy computing.
