Hi Dave, when I execute the snmpd command in root account rather than using sudo it works perfectly fine and responses all queries.
[root@volga]# /home/ravi/net-snmp-5.5/agent/snmpd -c /home/ravi/net-snmp-5.5/local/snmpd.conf,/var/net-snmp/snmpd.conf -C -f -Le Cannot find module (IP-MIB): At line 0 in (none) Cannot find module (IF-MIB): At line 0 in (none) NET-SNMP version 5.5 --- --- Similarly when I use sudo command on non-root user (please note without -u option). it works fine as well. [ravi@volga]$ sudo /home/ravi/net-snmp-5.5/agent/snmpd -c /home/ravi/net-snmp-5.5/local/snmpd.conf,/var/net-snmp/snmpd.conf -C -f -Le [sudo] password for ravi: Cannot find module (IP-MIB): At line 0 in (none) Cannot find module (IF-MIB): At line 0 in (none) NET-SNMP version 5.5 ---- ---- Problem comes when I try to switch back to non-root user using -u option. After running snmpd using sudo. In this case snmpd quits with error "initgroups failed: Operation not permitted." [ravi@volga]$ sudo /home/ravi/net-snmp-5.5/agent/snmpd -c /home/ravi/net-snmp-5.5/local/snmpd.conf,/var/net-snmp/snmpd.conf -C -f -Le -u ravi Cannot find module (IP-MIB): At line 0 in (none) Cannot find module (IF-MIB): At line 0 in (none) initgroups failed: Operation not permitted [ravi@volga]$ snmpd fails to start in this case. Moreover I do not want to use SUID bit. As setting SUID bit on executable has its own risks Please suggest.
