Delay in sftp/ssh login

Hello, for some reason I have delay when I'm loggin in into my linux box, I have RedHat AS3.0.

I suspect that it's due to some timout I have somewhere, but I don't know where to look for it.

(btw, I don't use dns, onlt /etc/hosts, so it can't be DNS timeout on resolv)

thanx!

Re: Delay in sftp/ssh login

Probably it is a DNS issue. Check your /etc/hosts, /etc/resolv.conf, /etc/nsswitch.conf files.

Re: Delay in sftp/ssh login

If I remember correctly, the default behaviour is for ssh to reverse-lookup your IP for a hostname. This can cause the delay you are seeing. What happens if you put your connecting IP and hostname in /etc/hosts? I assume your /etc/nsswitch.conf file only refers to hosts being resolved by "files", rather than "dns" then?
