List IP Addresses on LAN

[LuckyTaxi]

I came across TCPNetview, and it's exactly what I want, but it shows me every IP address on the WAN!
I just want my immediate network (192.168.37.? LAN), and not the whole enterprise.

TCPNetview takes forever cuz it will show me every IP Address, and that's over 1500 PCs!

I think you can use nmap to scan a network block. Try that. Or saint.

sorry...forgot to mention this is for Win2000

Try nmap 🙂

i doubt u can. they are planning to port it to NT.
I found languard network scanner. it is very fast and does what i want!

now i have to figure out why my firewall is not working. damn linksys.
says port 80 is open when it isnt!

Hrmm... Ok, maybe I was wrong. I really thought they had ported it to nt. Well kudos for Fyodor! Keep the kids where they belong 😉

ummm....

to list all adresses on your LAN, you do the following magic:

subnet length = FFFFFFFF - netmask
broadcast = network + subnet length

and all available IP's you can use are between 'network' and 'broadcast'. Your box's IP shoud be among them.

From a Linux box (probably any unix) ping the broadcast address and save all the replies.

There is a version of nmap for NT, but I had problems getting it to work on Win2K, maybe it'll work better on NT4.
