Greetings,
I need a way (either via C# or in a .bat file) to get a list of all the computers on a given network. Normally, I use ‘net view’, but this tends to work (from my understanding) only within your domain. I need the names (or at least the IP Addresses) of all computers available on my network.
Being able to get all computers on a domain that isn’t mine (in which case I’d use WORKGROUP, or whatever the default is) would also work.
Nmap is good for this – use the -O option for OS fingerprinting and -oX ‘filename.xml’ for output as xml that you can then parse from c#.
A suitable commandline would be (where 192.168.0.0/24 is the subnet to scan):
leave out the -O if you aren’t interested in guessing the OS – if you just want a ping sweep use -sP, or read the docs for the myriad other options.
