Hi,

=20

I am trying to port some scripts we use via "extend" from Linux to AIX
5.2 and have noticed errors with the AIX agent that I can't account for.

For example, the snmpwalk below runs a script on the agent to report
number of available CPUs.

=20

Both agents are net-snmp 5.4.1 and both execute the same shell script.
The relevant line in snmpd.conf is:

=20

extend .1.3.6.1.4.1.5555.1 procNum /usr/local/bin/snmpproc procNum

=20

In the AIX version, I am getting "Cannot find terminal" messages in the
walk, which confuses my poller.

I have tried redirecting standard error from the script to /dev/null,
but that made no difference.

=20

Is there any reason why extend behaviour would be different between the
two platforms?

Has anybody else seen this AIX? Any suggestions on how to fix?

=20
