Testing SNMP

SNMP can be tested by running the Snmpwalk command. If SNMP has been configured successfully, this command generates a large amount of output.

The code is as follows:

root@server:~# snmpwalk-c mycommunity 172.17.1.44-v1

iso.3.6.1.2.1.1.1.0 = STRING: "Linux mrtg 3.5.0-17-generic #28-ubuntu SMP Tue Oct 9 19:31:23 UTC \ x86_64"
