I'm somewhat new to Linux, but I'm trying to network a few Linux machines. I can't seem to be able ping the gateway or the other Linux machines.
My scenario: I have a few Linux boxes set up on a
10.45.89.x subnet with the gateway being
10.45.89.1. On all of these, I'm unable to ping anything except
127.0.0.1. I'm wondering if I need to modify any of the routing tables or hosts file. Below is a few commands and their output. Perhaps I need to check something else?
netstat -r output:

Any suggestions are greatly appreciated. Thanks!
