Hi,

I have one ADSL link as my WAN uplink (actually, it's my backup, so it not used frequently). Is there any way I can use snmp to monitor if the link is working? I used snmpwalk to download all the MIB data from monowall, but could find which information I could use to monitor this.

I use Nagios for monitoring, and Monowall 1.8.1 (recently updated from 1.3.4).

Tks for any help,

If you mean Layer 2 "Link" up, than yes, SNMP can give you this.  And that will tell you that the cable is connected to your DSL modem.  Not useful.  SNMP has no way to tell if you are connected to the Internet at large, which is what you really want.  You would need something like ping to do that.

With more details, we could probably design something for you that would work.  What are you using for monitoring?
