Re: [Networktest-sctp] [SCTP] Problem in execution of SCTP first test case, please help.

[Mohd. A. <moh...@gm...>]

Hi Wei,
Thanks for the response!

I tried the same yesterday.

TN:
File: SCTP.pm
Function: sub sctpRemoteCommandAsync and sub sctpRemoteCommandAsyncDelay
Statement: vRemote("rcommand.rmt", "cmd=\"sleep $dalay && $cmd\"") && return 1;

NUT:
The command $cmd get executed. The NUT sends a INIT to TN, the TN
replies with INIT ACK, but then NUT replies with an ABORT instead of
COOKIE ECHO.
Reason: $cmd at NUT dies immediately just after sending INIT to TN.

I'll reply to other queries of yours once i reach to the LAB.
Can there be any other alternative?
Please suggest.

Thanks,
Arif
