You have a lot of questions, of which I do not know if I can answer all.
To set your system's host name, you can go through the pull-down menus to launch the Network Administration GUI (System->Administration->Network
) to set the hostname (goto the DNS tab), or you can edit the file /etc/sysconfig/network
and set it there. It's easiest to perform a reboot to ensure that the system as a whole picks up the change in the hostname.
As for registering each system with the other, you can create aliases in the /etc/hosts file. Once again, you can use the Network Administration tool referred to above (goto the Hosts tab).
After the changes are made, you should immediately be able to ssh (or ping) the other system using the alias. For instance:
user@PC1 $ ssh PC2
Now, as far as static IPs are concerned, it is not too difficult to set up, however when I first installed F8 I noticed that it did not accept my settings. I've heard through the grapevine that perhaps NetworkManager is to blame. Nevertheless, the easiest way to set it up is to once again rely on the Network Administration tool. You will need to select the interface (e.g. eth0) from the Devices tab, and from there click on the Edit menu button.
In the middle of the dialog that pops-up, the default setting for DHCP is probably selected. You want to select the "Statically set IP addresses", and then enter your information. For instance:
Then reboot and cross your fingers that the settings will remain intact without Network Manager interfering.
P.S. You could always disable Network Manager using the Service Configuration GUI.
