ndd operation failed - invalid argument

[Richard I Curtis]

Hi,
I am trying to list tcp_status so I can kill some CLOSE_WAIT sessions caused by a broken application..
When I try to get the values, it fails with "operation failed, invalid argument"..

ctr3 #ndd -get /dev/tcp ?|grep tcp_status
tcp_status (read only)
ctr3 #ndd -get /dev/tcp tcp_status
operation failed, Invalid argument
ctr3 #

Am I missing a trick here?

What version of HPUX ? Old OS ??

What patch/version of ndd ? Need a patch ??

[Richard I Curtis]

Its 11i (11.11) with the Jun 07 patch bundle applied.

The only patch that matches the operation failed, invalid argument error is PHNE_37671 although it does not mention my specific case - I guess it is worth a look.

Should my command above work correctly or am I making a mistake somewhere?

I get the same error on my 11.11 servers, command works on 11.23.

So it is not just you ;)

Hi Richard:

This works OK for me on 11.11 with December 2007 GOLDAPP & GOLDBASE bundles. I don't have PHNE_37671, but I do have PHNE_35351.

Regards!

I have neither of those patches so will apply the most recent one when I can get a downtime and if that doesnt solve it, will have to log a call with the response centre.

Thanks for the replies.

How about simply using "kill" against the broken application. (I've never really liked tcp_discon*... :)

ISTR some issues with streams message sizes and the ability of ndd to report a full tcp_status. Some web searching might find the specifics - would hae thought that contemporary 11.11 patches would be OK, but perhaps some tuning is still in order.
