SNMP: Number of active ports

Bruno as far as I remember - no but (assuming that you have a unix box) you can snmpwalk thru the status of the ports then pipe it to the "grep" and calculate it with "wc -l"

hope this helps Roman Nakhmanson

-Number- of connections is not in the standard MIBs.

You can walk the ifOperStatus subtree and count the ones that are up .

BTW... it doesn't take a unix box. I've done it from Unix, Apple Macintosh, Linux AND Windows... It just takes an IP stack and snmp programs like snmpwalk, snmpget, snmpset etc.

On the Mac with OS9, and in Windows, how did you pipe the output of the programs to grep and wc ?

The responder wasn't saying you couldn't get at the information from other boxes: the respondant was talking about processing the information after it was fetched.

Searching Google for "grep for windows" or "wc for windows" returns plenty of options.

Besides being able to grep, awk, sed, and a whole host of other "unix" like utilities on the Macintosh... There's no reason you can't use Perl to parse out what you need. (yes, Perl runs on the Mac)

In short, there's no OS that I'm aware of that can't do what Bruno was asking for. - including "processing the information after it's fetched".

In fact, I would lay odds that someone has already written a publicly available Perl script to do exactly what Bruno was asking for.

Try googling for something like: perl snmp ifOperStatus
