ndd command getting errors when attempting to change parameter

[Kevin_102]

Hello all,

I'm attempting to change a parameter doing the below command...

ndd -set /dev/tcp tcp_keepalive_interval 600000

and I get "operation failed, Invalid argument."

What am I doing wrong? Is this parameter dependent on another?

Thanks!
Kevin

Forgot.....this is a HP-UX 11.11 box.

Thanks

Also, are there 11.x equivalencies for the following from 10.20?

Thanks

tcp-keepstart, tcp_keepfreq and tcp_keepstop

Hi Kevin,
I believe this was caused by a high number of tcp connections (checked with netstat -sn | grep ESTABLISHED). A work around was to set STRMSGSZ to 0 (which means no limit). Check the latest ARPA patch, also.


Run these commands on 11.x systems to find supported and unsupported ndd tunables:

#ndd -h sup[ported]

#ndd -h unsup[ported]

for 10.20, run

#nettune -h

Regards,
Berlene
