When trying to get the Dell OpenManage Server Administrator (OMSA) working with SNMP I got the following error:
snmpd: /etc/snmp/snmpd.conf: line 23: Warning: Unknown token: smuxpeer.
On older Ubuntu server you need to remove
-I -smux from the file
On the newer Ubuntu 18.04 you also need to change the following file:
The line should look like this:
ExecStart=/usr/sbin/snmpd -Lsd -Lf /dev/null -u Debian-snmp -g Debian-snmp -I -smux,mteTrigger,mteTriggerConf -f
Change that line into:
ExecStart=/usr/sbin/snmpd -Lsd -Lf /dev/null -u Debian-snmp -g Debian-snmp -f
After that you need to do a reload of the daemon config and restart SNMPD:
systemctl daemon-reload $$ service snmpd restart
Now you are done and you can get the Dell OMSA working through SNMP.
