    LAN DOS command

    Hi, i have a LAN at my house, and i was wondering if there was a command in DOS that would let me see all the IPs of every individual computer that is on my network. I only have 3 computers. All of them connect through a Router. And I have file sharing enabled. Any answers would be appreciated.

    well you could look at the router interface and find out that way, or you can goto each individual computer and type "ipconfig"... if you would like to access shared resorces you can always click on "network naborhood" (if you are using windows)... as far as a DOS command i am not awaire of one....

    a port scanner is always a good option as well...

    one way to make it a little easyer is to use the DHCP service on your router to give each of your computers a static IP address..... if you need help doing this please ask....

    A quick way can be to use the ping broadcast. e.g., if you are using 192.168.1.x for an ip range then do ping -t 192.168.1.255. After about 15-20 seconds hit CTRL+C to stop it and then arp -a to see a listing.

    MsM: A windows machine doesn't respond to a broadcast ping (by default). No machine should reply. If it did his network would be susceptible to a smurf attack...

    http://www.cert.org/advisories/CA-1998-01.html

    Since you're using a broadcast the layer 2 address would be ff:ff:ff:ff:ff:ff. Because none of the machines should respond your arp table will remain empty.

    Hi, "net view" should give you a list of computer names. You can then find their IP addresses easily... I'm not sure on which Windowses the command is available. Also, my box/network is so "secured" that net view doesn't work.

    If you have a W2K/XP box, a brute force solution can be used:
    for /L %i in (1,1,254) do ping -n 1 192.168.1.%i
    ::while waiting the for loop completes, you can see which IP is responding
    arp -a

    Peace always,

    Ok, i'll try all of those commands... and devildell, i dont want to get up and go to every individual computer and look up their IP... thanks anyway...

    jdenny?: for /L %i in (1,1,254) do ping -n 1 192.168.1.%i < that was pretty cool, it said bad parameter for all of them though. net view only gives me the computer names not their IPs.

    msmittens?: if i didn't ]know my IP range (eg. 192.168.1.x) how would i look up the ips connected in my network?

    Really? What's your win version? Can you post the detailed message?

    Do a "ping computer_name" for each of them... If you have NetBIOS over IP or NetBeui enabled, it should work.

    Hi

    Create a bat-file and put the following code in it
    Code:
    for /L %%i in (1,1,254) do  ping -n 1 192.168.1.%%i
    This should run, as well as Jdenny's command works exactly as it should,
    in the command prompt.
    Did you forget the dot before %i? What is your OS?

    Cheers.
