Are you using Windows or Linux at the moment? If Linux use nmap to scan your network.
e.g. to scan my network, I would have to use
Code:
nmap 192.168.1.1/21
It might vary . Especially 192.168.
1.1/21
is in every network a bit others. And 192.168.1.
1/21 shows the first and the last ip to scan. Nmap will give you all the services, that are given.
If you use Windows, I don't know what you can use. Try to scan the network with I don't know what there might be.
If you have luck and you have a Linux running with ssh or telnet you can use in Linux ssh or telnet command and in Windows a app called putty to access them.
