UNIX for Advanced & Expert Users

Hi, I am wondering how I can find the network address under following situation.

Things available:
1. An active network drop without knowing any details about the network.
2. I have windows, Linux, and Solaris machine available to use.

Things to achieve:
1. Find out the details of the network, such as network IP, net mask.

Thanks,
Jason

try ipconfig on windows and ifconfig on unix

Hi, Thanks for the quick replay. ipconfig or ifconfig both read information about the interface on localhost. The issue is that there is no DHCP server on this network(sorry!, I forgot to point it out.), so the interface on localhost will not get IP from other servers.

You are mentioning the network IP and netmask... well, 'ifconfig -a' will give you both those things won't it? Check the below output from my own home network:

Code:

inet addr:192.168.1.24  Bcast:255.255.255.255  Mask:255.255.255.0

Now from the above info, you have the inet addr, and the netmask. You just mask the inet addr using the netmask to get the network address.

Guys, Jason here seems to be either asking help on his homework assignment, or he's got an illegal feed/piggybacking on someone's wireless connection. Otherwise, how can you not know what network you are in?

Other than that, ask the guy who set up the switch!

Thanks for system shocks' good guess. The funny thing is that there is a drop on the wall at my working place, since this is a big worldwide company, nobody knows which network that drop connects to(does this ever happen at your company? my guess is not!). At first, I thought some kind of broadcast methods can sort things out, but it tiurns out not that easy. This is very interesting thing, don't you agree?
