Network Monitoring

By shawn.dejarnatt ·
I've currently been asked to monitor a network with approx. 4000-5000 nodes. We currently have no monitoring equipment in-plant, and are experiencing problems with duplicate IP addresses. Until we buy the appropriate software, are their any perl scripts or free software that can resolve IP addr. routes, including IP addresses of the connected switches?

Try www.languard.com , downloads, Languard Network Scanner. This is a free network scanner software that will check a range of ip's that you select and retreive information from the respective computers. Put small range of ip's in at first to test it's abilities.

Is this a LAN or WAN interconnected LAN's?

I'd guess from the size that it's the latter, and you mention Switches, so that could limit your abilities to use packet sniffer type products.

A good, free, packet sniffer is available from www.ethereal.com, but the Switch will stop the "all traffic" forwarding.

Depending on the switch, you could look at the ARP tables to find the duplicate IP/MAC addresses.

NBTSTAT -a [ip-addr] from NT will show you who's logged in (NT Wkstn) or the Machine Name (W9x)

Have Fun!

Jason.
