Red Hat Enterprise Linux 5.3 login time too long

Hi everybody
I have a Red Hat Enterprise Linux version 5.3 running on two Integrity machines.

After entering the root password the # prompt take almost 10 to 12 second to appear.
This only happen in one node, in the second node after entering the root password the # prompt come inmmediately.

Some idea , every thing is ok , just by single detail.


Regards

Login HOW? Serial port? Telnet? rsh? ssh?
...?

A Forum search for keywords like, say
slow telnet
(or whatever) might find many old threads on
similar complaints. One popular problem is a
(reverse) DNS look-up problem, where the
(Telnet, rsh, ssh, ...) server system has
trouble getting the name of the client host
from its IP address. It's also possible for
some operation in a shell start-up script
(~/.profile, or whatever) to take excessive
time for some reason.

So, adding "-v" to the "ssh" command might
provide a clue as to where it's getting
stuck.

But it's pretty easy to try something like:
nslookup
on the server, which should reveal a DNS
problem if there is one.

any chance you have ipv6 enabled on the machine with the 'slow' login syndrome? please check and turn it off if you're not using it (probably not).

Shalom,

1) Quick fix is to make sure the system can look itself up in /etc/hosts instead of waiting for DNS. This usually stops 50% of these issues.
