I don't see anything unusual in them, and I haven't changed them. Also,
they are the same as the same files on the other servers, and those
servers don't have this problem. I've tried this from several different
servers. I've also asked others to try, and they have the same problem.
try ssh -vv user@wherever to see where the hang is happening.
On the server try dig -x client.IP.add.ress to be sure reverse DNS works.

Subject: delay after ssh'ing into a server
I am having an odd problem with one of my RHEL servers. When I issue
the command to ssh into it:
$ ssh aa
there is a 30 second delay before I get the password prompt. I tried
deleting the appropriate line in ~/.ssh/known-hosts and trying it
again, but I still got a 30 second delay before I got this message:
The authenticity of host 'aa (10.1.5.93)' can't be established.
RSA key fingerprint is <a:long:hex:number>.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'aa,10.1.5.93' (RSA) to the list of known
hosts.
This is what the log looks like during this time:
Oct 5 14:52:30 aa xinetd[3098]: START: ssh pid=23524 from=10.1.5.58
Oct 5 18:53:12 aa sshd[23567]: Accepted password for bjt from
10.1.5.58 port
32818 ssh2
Oct 5 14:53:12 aa sshd[23524]: Accepted password for bjt from
10.1.5.58 port
32818 ssh2
Notice the 42 second time delay. The first line appeared in the log
just after I send the "ssh aa" command.
I must have done something to make the system delay after receiving
the connection request, but I can't imagine what. Googling turned up
nothing for me.
Any ideas?
