TCP Parameters on HPUX 11.31

[SivaOX]

I got no responses in the networking forum, so I thought I would chance a cross-post.

I need to set following TCP Parameters in HPUX 11.31 server.

1.Delay Acknoledgement time

2.Keep Alive Time

3.Keep Alive Interval

4.TCP Time wait

5.Keep Alive retry count

But i could see only the following parameters can be set through NDD,

tcp_keepalive_interval

tcp_time_wait_interval

Please help me to configure other parameters. thanks.

"ndd -h" should list the parameters available.

perhaps the better question is -- why do you want to know about these?

Hi Donna,
Thanks for the reply.

The mentioned settings were on Windows box (Registry settings); and i need to configure these settings in my application server (HPUX 11.31).

i'd configured the "keep alive" settings by NDD conf. (Ref: https://www-304.ibm.com/support/docview.wss?uid=swg21231084)

and need to configure the followings to make the similar behaviour of the windows server.

Delay Acknoledgement time (TcpAckFrequency)
TCP Time wait (TcpTimedWaitDelay)

Is there any equvilant parameter on the HP UX?

Thanks.

the ibm support document you referenced discusses changing:

• tcp_time_wait_interval
• tcp_keepalive_interval
• tcp_keepalives_kill (1)

(although there's no mention of how to change the "interval" values)

the other parameters appear to be microsoft-only.
