| - | ====== Net-SNMP with SNMPv3 Trap ====== | ||
| - | ===== How to? ===== | ||
| - | ==== /etc/sysconfig/snmptrapd ==== | ||
| - | 先加debug log: | ||
| - | <code bash> | ||
| - | OPTIONS="-Lsd -Lf /var/log/snmptrapd.log" | ||
| - | </code> | ||
| - | 之後可以執行以下cmd去看接收trap結果: | ||
| - | <code bash> | ||
| - | tail -f /var/log/snmptrapd.log | ||
| - | </code> | ||
| - | ==== /etc/snmp/snmptrapd.conf ==== | ||
| - | <code bash> | ||
| - | createUser -e 0x8000123acd1ab43abbfff000fa opsviewv3 SHA mySecureAuthPassword AES mySecurePrivPassword | ||
| - | createUser -e 0x80001370010a921096 opsviewv4 SHA-224 mySecureAuthPassword AES mySecurePrivPassword | ||
| - | authUser log,execute,net opsviewv3 | ||
| - | authUser log,execute,net opsviewv4 | ||
| - | createUser -e 0x8000000001020505 ovirtengine MD5 authpass AES privpass | ||
| - | createUser -e 0x8000000001020606 NoAuthNoPriv | ||
| - | authUser log,execute,net NoAuthNoPriv noauth | ||
| - | authUser log,execute,net ovirtengine | ||
| - | |||
| - | forward default 10.146.125.32 | ||
| - | </code> | ||
| - | Note. 有發現如果opsviewv3設定過SHA，再設定為SHA-224會沒用，根本原因還沒時間找。 | ||
| - | ==== test commands ==== | ||
| - | <code bash> | ||
| - | snmptrap -e 0x8000123acd1ab43abbfff000fa -v 3 -u opsviewv3 -a SHA -A mySecureAuthPassword -x AES -XmySecurePrivPassword -l authPriv localhost 1 0 | ||
| - | snmptrap -e 0x8000123acd1ab43abbfff000fa -v 3 -u opsviewv4 -a SHA-224 -A mySecureAuthPassword -x AES -XmySecurePrivPassword -l authPriv localhost 1 0 | ||
| - | snmptrap -v 3 -n "" -l noAuthNoPriv -u NoAuthNoPriv -e 0x8000000001020606 localhost 0 linkUp.0 | ||
| - | snmptrap -v 3 -n "" -a MD5 -A authpass -l authNoPriv -u ovirtengine -e 0x8000000001020505 localhost 0 linkUp.0 | ||
| - | snmptrap -v 3 -n "" -a MD5 -A authpass -x AES -X privpass -l authPriv -u ovirtengine -e 0x8000000001020505 localhost 0 linkUp.0 | ||
