Hi everyone,
I'm very new to SNMP, Net-SNMP, and the field in general, so please have pa=
tience if there is an obvious fix to this.
I'm trying to configure an extend directive in the net-snmp/27/snmpd.conf f=
ile; 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 s=
cript errors. It looks like:
#!/bin/bash
echo Test
After restarting the daemon with a sudo snap restart net-snmp, the output o=
f 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 nsExtendC=
ommand line, however, points correctly to /tmp/classmonitor.sh. It seems li=
ke 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 sh=
ows that the script outputs fine into the terminal when run by itself.
Any troubleshooting would be much appreciated. Thanks!
