hi, all I'm recently working on a project using net-snmp. After configured following the man page, my snmptrapd seemed not to receive any notification, or maybe snmpd didn't send any.
This is my configuration. Both the snmpd and the snmptrapd are on one machine. ------------ 1. /var/lib/net-snmp/snmpd.conf createUser agentuser MD5 mypassword createUser internelUser MD5 mypassword ------------ 2. /var/lib/net-snmp/snmptrapd.conf createUser -e 0x8000000001020304 trapuser MD5 mypassword createUser infromuser MD5 mypassword ------------ 3. /etc/snmp/snmp.conf defVersion 3 defSecurityLevel authNoPriv ------------ 4. /etc/snmp/snmpd.conf trapsess -e 0x8000000001020304 -u trapuser -A mypassword localhost iquerySecName internelUser rouser internelUser noauth rwuser agentuser auth linkUpDownNotifications yes defaultMonitors yes proc ssh 3 # We do not want annoying "Connection from UDP: " messages in syslog. # If the following option is commented out, snmpd will print each incoming # connection, which can be useful for debugging. dontLogTCPWrappersConnects yes ------------ 5. /etc/snmp/snmptrapd.conf authUser log trapuser auth authUser log informuser auth ------------ Then, I start the snmpd and snmptrapd and run 4 sshs # ssh 193.168.10.1 # ssh 193.168.10.2 # ssh 193.168.10.3 # ssh 193.168.10.4 I could confirm that prErrorFlag was set to be 1 as the manual said using snmpwalk. # snmpwalk -u agentuser -A mypassword localhost prTable UCD-SNMP-MIB::prIndex.1 = INTEGER: 1 UCD-SNMP-MIB::prNames.1 = STRING: ssh UCD-SNMP-MIB::prMin.1 = INTEGER: 0 UCD-SNMP-MIB::prMax.1 = INTEGER: 3 UCD-SNMP-MIB::prCount.1 = INTEGER: 4 UCD-SNMP-MIB::prErrorFlag.1 = INTEGER: error(1) UCD-SNMP-MIB::prErrMessage.1 = STRING: Too many ssh running (# = 4) UCD-SNMP-MIB::prErrFix.1 = INTEGER: noError(0) UCD-SNMP-MIB::prErrFixCmd.1 = STRING: Yet no trap log was output in /var/log/messages # cat /var/log/messages | grep snmptrapd Nov 7 17:58:58 localhost snmptrapd[24321]: Stopping snmptrapd Nov 7 17:58:58 localhost snmptrapd[26969]: NET-SNMP version 5.5 Nov 7 18:00:34 localhost snmptrapd[26969]: 2013-11-07 18:00:34 NET-SNMP version 5.5 Stopped. Nov 7 18:00:34 localhost snmptrapd[26969]: Stopping snmptrapd Nov 7 18:00:34 localhost snmptrapd[27005]: NET-SNMP version 5.5 Nov 8 08:51:03 localhost snmptrapd[2237]: NET-SNMP version 5.5 And after waiting for 10 minutes or longer, there's still no notification logged although the man page says the default frequency is 10 minutes. **the snmptrap command could work correctly** I was confused with it and did I miss anything? How to config to make the agent to send notifications actively and the receiver can receive it properly? Many thanks in advance!
