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).
