Have you tried using the verbose flag with ssh? It spits out a lot of information, but you could get some insight if it is getting caught up with authentication or resolving hostnames. I usually use it with three Vs: ssh -vvv myserver -Aaron On 12/15/2011 06:34 AM, Rob Owens wrote: > On Thu

I checked and resolv.conf had entries for IPv6 and also had a weird entry of 127.0.1.1 ncslts3 on the ncslts3 server. I commented out all the IPv6 entries and also the above line. Logins still take about 25 seconds to authenticate, but that is less than the 30 second timeout limit so they are wo

I'm not sure what else to suggest except that you take a look at /etc/resolv.conf and test lookups using the nslookup command. -Rob On Wed, Dec 14, 2011 at 07:38:44PM -0500, David Hopkins wrote: > Yep .. that is exactly what mine looks like and it gets overwritten at > each client though I do not

All, I am beginning to suspect this issue is because ssh isn't resolving names correctly? Timing ssh myserver from a shell (ALT-CTL-F2) takes about 30 seconds to resolve myserver. However, ssh any_other_server returns immediately. So, why wouldn't myserver resolve quickly? This is true from a

We are having a major issue with thin client authentication. It started just after lunch time today. Authentication works fine from console and on terminal, but ssh takes a very long time to connect. One server (out of 5) can still connect though the login process takes quite a while to complete.
