computers on network

How do I find which computers in the network are working(connected) and which are not.

depends what you mean by "connected" or not... in my world that question would be answered with a ping, is that all you need? in actual fact if i wish to find all machines (that don't block icnmp) in my local lan i'd use fping to hit every possible address at once.

Finding boxes which are not connected to your network would be real difficult ask.

Otherwise you can ping the broadcast ip & see from which boxes did you get a reply.

And as Acid has prompted you an option of fping;

fping is a ping(1) like program which uses the Internet Control Message Protocol (ICMP) echo request to determine if a host is up. fping is different from ping in that you can specify any number of hosts on the command line, or specify a file containing the lists of hosts to ping. Instead of trying one host until it timeouts or replies, fping will send out a ping packet and move on to the next host in a round-robin fashion. If a host replies, it is noted and removed from the list of hosts to check. If a host does not respond within a certain time limit and/or retry limit it will be considered unreachable.

Unlike ping, fping is meant to be used in scripts and its output is easy to parse.
