Hi, I've been trying to use nagios with snmp version 3. Unfortunately, it seems that the check_snmp script formats the security level for version three authentication incorrectly. All of these commands are run by the nagios user. I also have all the authorization information saved in an snmp.conf file readable by the nagios user ----------------------- $ ./check_snmp -H hostname -o sysUpTime.0 -P 3 -L [authPriv] -v yields: /usr/bin/snmpget -t 1 -r 5 -m ALL -v 3 (null) hostname sysUpTime.0 SNMP problem - No data received from host CMD: /usr/bin/snmpget -t 1 -r 5 -m ALL -v 3 [authpriv] hostname sysUpTime.0 ----------------------- (without seclevel specification): $ ./check_snmp -H hostname -o sysUpTime.0 -P 3 -v yields: /usr/bin/snmpget -t 1 -r 5 -m ALL -v 3 -l noAuthNoPriv hostname sysUpTime.0 SNMP problem - No data received from host CMD: /usr/bin/snmpget -t 1 -r 5 -m ALL -v 3 [authpriv] hostname sysUpTime. ----------------------- But the command: snmpget -t 1 -r 5 -m ALL -v 3 tamarind sysUpTime.0 -l authpriv produces the proper output from snmpget. ----------------------- Basically, I want to know why the brackets are added and how I can get rid of them, or how I could make this command work. Thank you, -Meggie
