I am trying to make a bat file to run on a win2k pro machine that will ping an ip range (ie 192.168.10.1 - 192.168.10.254 and pipe the info to a text file. I had one years ago adn lost it. I can do it in a unix environment but having problems in the windows environment.

how about ping -n 5 192.168.10.1 > ping.txt -n 5 means ping the ip 5 times

Hi Oranda i think this is what you are looking for! Instead of manually pinging all IP addresses on your LAN you can use this nice command: Open Command Prompt and type: FOR /L %i IN (1,1,254) DO ping -n 1 192.168.0.%i | FIND /i "Reply">>c:\ipaddresses.txt The "-n 1" is for only 1 ping packet to be sent to each computer. Change 192.168.0 to match you own Network ID. This will ping all IP addresses on the 192.168.0.0 network segment and create a text file called IPADDRESSES.TXT in C:\, where it will list only the IP addresses that gave a reply. You can also add a -a to the PING command to resolve all the responding IP addresses to HOST names, but doing so will cause the script to take a considerable time to finish: FOR /L %i IN (1,1,254) DO ping -a -n 1 192.168.0.%i | FIND /i "Reply">>c:\ipaddresses.txt don't forget to type the command in 1 line.

Great thanks Saleh

Now that I tried it, I am getting syntax errors. Any ideas?
