extend errors on AIX 5.2

Hi,

 

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.

 

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

 

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

 

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.

 

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?
