which ndd tcp parameters would affect the timeout of a telnet?

[Dan Copeland]

Admins,

I'm trying to determine what parameters you would need to change to decrease the time you wait for a telnet to timeout attempting to telnet to a down (but resolvable) node.

This is 11.11.

Hi,

I believe tcp_keepalive_interval is the paramter you should look at.

http://www1.itrc.hp.com/service/cki/docDisplay.do?docLocale=en_US&docId=200000069216208

The itrc doc id is KBRC00012873.

Hope this helps.

Dan,

I don't think the above answer is correct for a timeout value for a new session.
I think the ndd configurable parameter that you are looking, at which time telnet would time out un reachable attempt would be

tcp_ip_abort_cinterval

It's default vaule is 75000ms = 75sec = 1:15m

To verify it, do,
# time telnet downip#
This should time out and give you the time it waited.
and compare the value with the output of,
#ndd -get /dev/tcp tcp_ip_abort_cinterval

Check it out.

HTH,Abdul.

Thanks Abdul. That's what I needed.
