hi,

it could be a problem with DNS or NIS issue.

# cat /etc/resolv.conf
domain accrcb.corp
nameserver 160.173.16.4

when i am trying to ping to this ip it continously pinging, so i suggest no issues with the DNS.

Which kind of "remote session"? Telnet?
RSH/remsh? SSH? ...???

I suggest testing the DNS before deciding
that there are no problems with the DNS.

On the server, try:
nslookup


Or, try a Forum search for keywords like
slow telnet
and read some the very many old, similar
threads.

when i am taking telnet its gud fast and conecting immdeatly.

nslookup to that ip is saying non-existent domain.

[Bill Hassell]

The 20 second delay is due to a DNS failure. The ping to the DNS server only indicates that the box is running. nslookup and nsquery must return the IP address *and* the hostname for your local machine (another system or your PC). Assuming you are using a PC and the PC's name is pc123 and the IP address is 12.34.56.78, then these 4 commands must return normal results:

nslookup pc123
nslookup 12.34.56.78
nsquery hosts pc123
nsquery 12.34.56.78

If any of this fails, your DNS server is not providing your PC's information and there will be a timeout (20-30 seconds) for every DNS server listed in /etc/resolv.conf. In other words, your DNS server is not accurate.
