Connect my non wireless enabled pc to my wireless enabled pc via ethernet?

Help me im dumb · 10-21-2012, 12:21 PM

I want to use my laptop that receives wifi as a server for my pc that does not have a wifi card, both run linux mint.

I have set up a connection with network manager and set IPv4 method to "Shared with other computers" and it connects fine apparently but i cannot browse due to "Server not found".

"Server not Found" might come about if both computers are not in the same subnet.

From your post, for the computer you show the ifconfig result for, it indicates it is in subnet 10.42.0.x. You need make sure that the other computer is in the same subnet. That mean that the ip for eth0 on that computer ought to be 10.42.0.y. where y is between 1 and 254 and not the same as x (not 1, in your case). The broadcast address and the mask should be the same for both computers.

That should be your first step.

If not, it would help to see the result of running ifconfig -a on both computers and maybe we can take it from there.

OK, but we need it from both computers, not only the one! Both computers have to be in sync to communicate with each other.

But it looks like this one does not have an ip4 address which mean you probably have to fix the connection on this one via network manager. The ip6 address does not look right eiher. Anyway, try as per my first post and then , post back the ipconfig results if that does not work. Also, you will have to bring the interface down and up again after you make the change (try "ifdown eth0" and then "ifup eth0" on the computer where you make the change to the ip. You need to do this as root or sudo).
