Hi, I'm no network expert but I have some practical experience with
home networks.

The first thing I would do is check the IP addresses on your home
computers. Did you configure these yourself, or are you getting
addresses from a DHCP service on your router. The "ifconfig" command
issued on each machine should hopefully show you both/all machines
have addresses in the same network; likely possibilities are


If there is a DHCP service running on the router then the chances are
high that you can do what you want and perhaps you are being prevented
by firewalls on the computers themselves.

Using the Mandriva Control Centre go to the Security panel and
double-click the "Personal firewall"  option. While you are having
"fun" getting the net working it may be a good idea to disable the
firewalls by ticking the "Everything" box in the "Which services would
you like to allow the Internet to connect to?" list.

Now you can try the nmap command to see what your computer can see. It
should already be installed but it's no more than a quick "urpmi nmap"
away. My net is using 192.168.0.? so here is the output I see from

[root at Tureen rich]# nmap -sP 192.168.0.*

Starting Nmap 5.51.6 ( http://nmap.org ) at 2012-03-04 22:29 GMT

MAC Address: 00:10:4B:C3:BF:8C (3com)

That shows 1 other PC and my DHCP/firewall machine

Does any of this help?
