Hi everyone,

I'm very new to SNMP, Net-SNMP, and the field in general, so please have 
patience if there is an obvious fix to this.

I'm trying to configure an extend directive in the net-snmp/27/snmpd.conf file; 
I've set it up thus:

extend classmonitor /tmp/classmonitor.sh

I'm just having the script be a simple echo at this point to rule out any 
script errors. It looks like:

#!/bin/bash
echo Test

After restarting the daemon with a sudo snap restart net-snmp, the output of 
the snmpwalk for 1.3.6.1.4.1.8072.1.3.2 has the nsExtendOutFull line show an 
empty string, and nsExtendResult gives an exit code of 1. The nsExtendCommand 
line, however, points correctly to /tmp/classmonitor.sh. It seems like the 
daemon is somehow not able to get to the file or its output, but the 
permissions for reading/executing the file and directory align with what I have 
set for the user. Doing a su with the user running the daemon also shows that 
the script outputs fine into the terminal when run by itself.

Any troubleshooting would be much appreciated. Thanks!
