what about trying an snmpwalk ? sure, there should be some conditions in
place (comunity name, daemon active...) but, if conditions apply, you could
have all the if's information.

Re: Identifying whether 2 IPs are
from the same server
Try flooding one while watching the turnaround time on a ping to the
other one. If it is the same machine, the flood might occupy the network
stack and cause latency in the ping time from it's second IP. There are
situations where this might give you a false positive such as two
identical machines on an unswitched ethernet where the flood would
naturally slow the response of the second machine. It's not a perfect
plan but right off the top of my head that's an option. You can also use
nmap to scan it and hope the machines reveal their uptimes, if the
uptimes are identical then it could be the same machine or the admin
gets off on synchronizing the power on his servers lol.
If you were more explicit about which sockets were in use then you can
enumerate the two by looking at static files on the machines (web, anon
ftp, etc). If you can find two identical folders on each IP through
apache that doesn't have an index.html file you can compare the
timestamps on the contents of both folders. There's a bunch of little
things you can do.
I'm willing to bet 'nmap -O -p 0-1024 hostname' will tell you what you
need to know
