Commands for network resource discovery?

I was wondering how one would find network resources in Linux.  Both graphically and command-line.  For instance, is there a way to know about other Linux machines that might exist on the same subnet?  I think I would be able to figure out how to mount the file systems once I find them, but I don't really know how network resource discovery works in Linux.

Thanks for the help,

there is no general way, but numerous other ways to do it.
If you're not experianced to networks, I highly recommend that you ask other users using Linux on the subnet to tell you their hostname.
Then it's very simple:
   mount other-hostname:/name-of-share /mountpoint

This is also possible graphically, but depends on the used WindowManager and Desktop, each has its own solution for it.

So are you saying that resource discovery can only be accomplished graphically?  Isn't there some kind of broadcast command?  Graphically, I'm using KDE on RHL V7.1.

even the RPC protocoll (which is used by NFS) can handle broadcast, I'm nit aware of any standard functionality with broadcast. But there exist 3'rd party products which do it.

Take a look at Cheops (http://www.marko.net/cheops/).  I think in combination with Nmap http://www.insecure.org/nmap/) it could be a good tool to start up with.

cheers.

nmap looks great!  It has both graphical and command line.  Just what I was looking for!

about your mount question, I found a broadcast solution:

rpcinfo -b 100005 3|sort -u|awk '{print "showmount -e "$2}'|sh

# probably you need to replace 3 by 2 or 1, or use all three variants
