Network Inventory Discovery

Apr 04, 2005 5 Replies

Howdy,



i hope this is the correct news group to post this. i am hoping someone knows of some way to discover arbitrary ip subnets on a switched (VLAN'ed) network. Our PIX firewall has a fairly intensive IP routing Table and i have noticed that many ACL have no hits. Basically what i am looking for is a utility that do a ping sweep of all subnets for me so that i can ascertain what ip routes can be removed (if any). i have tried the usual stuff (nmap, fping, hping2 etc) but none have this functionality that i am looking for. Any suggestions will be most welcome


Thanks in advance dirk


If anyone is interested - i found a fast ping sweeper called wpsweep

Have you considered looking at the config on your switch? Geez, doesn't that seem to be logical, matching the config of the PIX to the switch? Come on guys, it's all common sense, you just have to use it.

I would have thought the following would have done exactly what you wanted:

namp -sP 10.1.1.1/16 192.168.5.0/22 172.16.240.2/24

how does your requirement differ?

you also have "angyipscanner".

Hi Justin

Thanks for showing the correct syntax. When using nmap, i had seperated the ip networks using comma's namp -sP 10.1.1.1/16, 192.168.5.0/22, 172.16.240.2/24 This was how it was depicted in the man page (Windows version). Anyway - perhaps i should have used more initiative when doing the command line options.
