Slow Telnet Response

[Learn_1]

We have lpha server ES40 running TRU64UNIX V5.1A. For the last 3,4 days i am having slow telnet response from server. it almost take 1:15 minutes before it response to telnet request. the network is 10/100.
which parameters do i need to check and modify to resolve this issue.

99% of that kind of problem are naming resolution problems. so check your dns etc.

Anwar,
Check to see if your ethernet interface is set to 100 base. Also make sure that the name resolution is ok

1. Is it only a particular host that you are
seeing this slow response with? If so i
suggest that you add an entry in the
local hosts file at /etc/hosts.

2. If item#1 doesn't help, i would check in
the DECevent logs to see if there are
any ethernet interface related errors

Can u perform some simple tests like

1. Telnetting to other hosts and let us know
if you see the same slowness. Try to
telnet to a host on a different network
segment.

2. Do you see any TCP/IP components related
slowness on this host

Anwar,
One more thing as advised earlier, if your n/w supports 100, then i would go ahead and set the ethernet interface on the host to 100 instead of 10/100 (autonegotiate)
