I connected my desktop and notebook computers, both are running linux
2.0.27, using the plip module. The desktop is set up as the gateway. The
strange thing is that the notebook can ping the desktop, but the desktop
cannot ping the notebook. I am new to networking. Does anybody know
what's wrong?
My first guess is the routing tables on the laptop. There is a program
called route which shows and sets the routing tables for linux. Routes
tell the kernel where to send things--if it doesn't know where to
send them, they don't go anywhere.
So, on you desktop, if you type in route -n, you should see something
like:
Destination Gateway Genmask Flags Metric RefUse Iface
127.0.0.1 0.0.0.0 255.255.255.255 UH 00 ... lo
IPaddress 0.0.0.0 255.255.255.0 ...
Where IPaddress is the address of your laptop. My guess is, your lap-
top doesn't have one of these lines. To fix that, try
route add IPaddress-of-desktop on your laptop.
If this doesn't work, or you want to know exactly how these routes work,
write me some email off the list.
