Solaris

Hi Guys and Girls, I know this is a common question but I've searched and we've tried the suggestions without luck. When I log into the box via SSH from a windows machine I get a 1 min 20 sec delay. If we add my IP address and machine name to /etc/hosts then I get an instant login. I would be happy with that as a solution except that it appears my IP keeps changing. Most of the posts I've looked at suggest this is a DNS issue which seems to fit as this machine times out if I type "nslookup bob" where on another server this returns instantly with an error. The timeout is 20 seconds which would indicate that when I log in it attempts to do 4 dns lookups?

I'm guessing the answer to this is fix the dns issue but that's not likely that easy. I don't know how this machine is connected to the network or even where in Australia the machine is located. It's a lab machine so likely doesn't have much access to anything. Assuming it can't reach a dns server can I work around this somehow? I found a post suggesting we put "UseDNS no" in /etc/ssh/sshd_config but this didn't help for some reason.

Thanks,
Michael

After adding the UseDNS configuration, did you reload/restart SSH? Otherwise it won't have any effect.

What is the host OS?

Thanks for the replies,

uname -a says this:
SunOS xxxxxxxx 5.10 Generic_139555-08 sun4v sparc SUNW,T5440
I've removed the server name in case it's not something I should publish.

Pludi, we did try restarting sshd.

I faced problems with SSH delays on Solaris. Check the SSH package version. We removed it and installed the latest OpenSSH and it solved our problem.

Code:

pkgchk -l | grep -i ssh

Is there a MOTD that appears when you login?

try doing a ssh -v or ssh -vv or ssh -vvv to view the 3 levels of debugging to determine where the system is getting stuck at.

Also what specs is your system running?

This might be the the server DNS setting problem. Assuming it can't reach a dns server, suggest is use your previous method to solve it
