You may also wish to look at cricket.sourceforge.net - like mrtg, but I
think its easier to use.

Everything has an index:(non-zero based)
snmpget host public interfaces.ifNumber.0

That will tell how many interfaces are on your box - probably 2, one for
lo and one for eth0.

Then
snmpget abyss shire interfaces.ifTable.ifEntry.ifDescr.1
snmpget abyss shire interfaces.ifTable.ifEntry.ifDescr.2
will get the descriptions for each.

try snmpwalk host public host
(The second host is literal - ie. snmpwalk myhost.com public host)

This assumes you have the UCD-SNMP installed with all of it's MIBS.
That'll tell you stuff even your mother doesn't know about you :)

Hope this helps.
