Severity: 4-Minor


During daemon startup, the snmpd daemon zeroes out sensitive data in the snmpd.conf files. This is done so that passwords are not available to be read on disk. This can cause problems when other daemons using the net-snmp shared libraries access snmpd.conf files for data that they need during startup.


Daemons usually start in an orderly fashion and usually do not conflict with each other. However, it is possible that they could fail to load correctly due to the zeroing out of data.


Depending upon the startup sequence, a daemon may need data from snmpd.conf files.


Use tmsh to configure SNMP users.
