#2695 Ubuntu 15.10 snmpd Permissions

[Anthony]

Net SNMPD will not properly run when using -u root -g 0 in /etc/default/snmpd

After stopping the snmpd service, I can "sudo" it in the foreground and it genrates DISMAN traps that are configured in the snmpd.conf file, but if running with -u root -g 0 (or -g adm) it does not generate any traps except coldStart.0 traps.

astump@astump15:~$ snmpd --version

Ok so this gets a bit more interesting. Somewhere I found on the net that you have to remove the mteTrigger, mteTriggerConf from the -smux line to get the DISMAN traps to work. I did this and all of a sudden I saw the traps working fine. But after I removed the mteTrigger,mteTriggerConf from the /etc/default/snmpd, now snmpwalk times out and I do not get a full set of mibs returned. I attempted doing download-mibs and sudo download-mibs again, but this does not fix it. I was able to get snmpwalk to work again simply by adding the mteTrigger/mteTriggerConf back in the SNMPDOPTS, but again, now DISMAN traps don't work.
