Try nmap

Will tell you IP, but not the hostname. AFAIK it is impossible to discover the hostname remotely unless of course it is a FQDN....or written in your hosts file, but then you wouldn't need to scan, would you?

i think nmap is not going to work as i am not use to this great tool but i will definately appreciate the great software.

i was using lately on windows a software that shows me ip and computer name for all the pc's and i am looking for similar software that can show me all the pc's on my network complete range of 255 numbers.

thanks

So what's wrong with nmap?

Assuming your net is 192.168.0.* then just do:

Code:

# nmap 192.168.0.0/24
or
# nmap 192.168.0.0-255

or whatever. This _will_ reveal the IP address of every system that is alive in that subnet.

As I mentioned, getting the hostname is not so easy because a UNIX machine will not advertise it's hostname over the network unless it is hopelessly misconfigured.

Of course.
Any computer running any OS will show up in the nmap scan. If you give it the -A or -O flag it will take a guess as to which OS/version/kernel is running. It is quite a powerful tool with many options (see man nmap for bedside reading).

I just want to say, make sure you are scanning _your_ network, and that it is allowed or you may get in trouble with the net admin (unless the net admin is you...)

i got it i used

nbtscan -e RangeOfIP

i got in the format of host file

192.168.2.2 abcPc

well i guess nmap is much more powerful but for my case this worked simply thanks
