while executing
"snmptrap -v 1 -c public localhost TRAP-TEST-MIB::demotraps localhost 4 0 '' IF-MIB::ifIndex i 1"
on my system,I am getting host ,ip & OID values as
host = localhost.localdomain :ip = UDP: [127.0.0.1]:49109->[127.0.0.1] :OID =DISMAN-EVENT-MIB::sysUpTimeInstance 0:3:12:38.28
But when traps are coming from outside its showing
host = :ip = UDP: [192.168.1.73]:52346->[192.168.1.23]:OID =DISMAN-EVENT-MIB::sysUpTimeInstance 7:1:05:54.27 .
Now its clearly shown above that host value didn't show up ...I want to know why & how it get to be resolve. Thanks in advance
回答1:
the one reason is if you are using VMware/virtual OS and you have not configured different IP than your host machine IP.
回答2:
Simply keep ip & its corresponding host-name in /etc/hosts file..That's All My /etc/hosts file is-
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
192.168.1.150 ZYXEL
192.168.1.73 CISCO
192.168.1.135 DIGISOL
