ping 192.168.1.2 or ping -c 5 192.168.1.2 The first case will keep sending pings untill you hit Ctrl-C, then second case will stop after 5 pings. You can use any value you like after the -c. The IP address is for the machine you are trying to get a responce from, not the machine you are on. But you can ping your own machine. So, you could use "ping -c 3 192.168.1.1", "ping -c 3 127.0.0.1", or "ping -c 3 localhost" to ping yourself from 192.168.1.1 - the last two forms should ping the machine you are on when run on any machine. > > I need to find out about ssh. > You may have to run "urpmi openssh-server" to install it. I don't remember if the server is installed by default. I always install it... If it isn't running, you can start it wil "service sshd start". I don't believe the default install will let you log in as root. What you usualy do is log in on the local machine as a normal user. If that user also has an account on the remote machine, then you can run "ssh <remote machine>" and connect. If not, then you can use the -l option to specify the remote user. "ssh <remote machine> -l <remote user>" >From 192.168.1.1, to connect to 192.168.1.2, it the sshd service is running on 192.168.1.2, you would run: ssh 192.168.1.2 or ssh 192.168.1.2 -l rosemary >> At this point, I would consider setting up dnsmasq on the modem machine, >> and letting it provide dhcp service for the network.
