View source for SNMP over SSH

'''Producer: '''The Server which you want to Monitor running net-snmp


'''Proxy: '''Accessible to Both to EM7 and to the Producer




'''Scenario:'''


I want to monitor my Personal System from EM7. I have setup Firewall to access my system. In that Only port 22 is open. You cannot access SNMP running on my personal system directly. So I have setup one Proxy Machine i.e. xyz which is accessible to EM7 and you can access my machine from xyz also.


'''Proxy Machine: '''xyz 192.168.0.1




'''Producer: '''76.175.20.215


'''On Proxy Machine:'''


ssh -f -N root@76.175.20.215 -L 6004:localhost:6004




'''Start TCP to UDP socat on Producer:'''


socat -d -d -d -lffoo.log TCP4-LISTEN:6004,fork UDP4:localhost:161




'''Start UDP to TCP socat on Proxy:'''


socat -d -d -d -lffoo.log UDP4-LISTEN:161,fork TCP:localhost:6004



'''Test by running snmpwalk on Proxy Machine:'''


snmpwalk -v1 -c public localhost
