The Ethernet connection on my RaspberryPi isn't working. After doing some research on StackExchange and other sites, I found the netmask to be the cause of the problem.
When I run
ifup eth0, it's using the wrong netmask
255.255.255.255. I want to set it to
255.255.255.0. I can confirm that this is my setting, because my laptop is using the same netmask.
This question describes the same problem, and the solution to that is to run the command
sudo ifconfig eth0 192.168.1.X netmask 255.255.255.0. I tried running this command but I get the error
host name lookup failure. When I changed the
X in the IP Address to a number, the command completes, but it still didn't work.
So is there any other way to change the netmask so that
ifup eth0 uses the correct one?
