Re: ssh in network

I was googling the 'no route to host' and found a suggestion to add a route
that poimts to the routerr with the command 'sudo ip route add
192.168.1.0/24 dev eth0'. So I thought that sounded good but after I did
not only could I not ssh out of the computer but I could no longer ssh into
the computer. I then tried to remove the route with the command 'sudo ip
route del 192.168.1.0/24 dev eth0', but that didn't help any. I just
realized that the ip address is wrong.... my router is 192.168.0.1 but:

sudo ip route add 192.168.0.1/24 dev eth0
