Very big delay (about 300 sec) before autentification
Dear all,
I got a problem and have no idea how to solve it.
I was searching in the forum and google it and have found similar problem but provided solution doesn't help me.
I have Solaris 11:
Code:
Oracle Solaris 11 11/11 X86
Copyright (c) 1983, 2011, Oracle and/or its affiliates. All rights reserved.
Assembled 18 October 2011
If I try to telnet or ssh to my Solaris 11 server I have to wait about 300 seconds before I get request for Login / password to login to the server.
If I try ftp - it connects immediately, but if I choose sftp - same story as with telnet and ssh..
Same issue when I trying to login from different servers which in different subnet (Windows and Solaris based).
Here is my /etc/hosts file:

As you can see from nsswitch.conf - I am not using dns.
Code:
root@solaris:~# ps -ef | grep dns
root 1497 1393 0 10:16:00 pts/1 0:00 grep dns
root@solaris:~#
If i run ssh in debug mode, I can see that it hanging here:
If I understand you correctly, clients experience a very long delay connecting to the Solaris box. So the fact that the Solaris doesn't use DNS is surely irrelevant. Question is what is the DNS setup of the clients.
What you describe has all the hallmarks of a DNS issue ie, name resolution delays (or possibly mis-routing on the network).
What if you telnet from a client giving the Solaris ip address instead of nodename?
What is the DNS environment that the clients are in????
