[ale] SNMP on Linux (Debian)

[Christopher Fowler]

Use net-snmp on the Linux box and use an NMS client.  
Just because there is a mib, does not mean that there is Linux support
for that mib.  In our case, we had to create our own MIB and we created
our own code to supply the data for that mib.

Net-SNMP has an RMON module, but currently there is not code in the
RMON (skeleton) module to provide useful data on a Linux host.  Any help
on that would be greatly appreciated by the folks at net-snmp.  I know
we discussed it many times before. And there have been many questions as
to why RMON gets do not supply any useful information.  

Here is my output
