Alright so, my Ubuntu system is up and running on my network. I just have a few generic questions.

1) In my /etc/hosts file, the first two entries are 127.0.0.1 and 127.0.1.1, the former of which is localhost, and the latter is my hostname. What is this 127.0.1.1? I'm familiar with loopback, but not 127.0.1.1.

2) Where can I specify what domain to put the computer on? I found how to do it in the GUI, but that's no fun. I want to learn how to do it the "real" way, sans GUI. Do I put the line "domain mydomainhere" into my /etc/resolv.conf, or is the domain stored elsewhere?

3) How is a network domain related to a Windows workgroup (if at all?) I have 2 other computers on this network, both of which run Windows, and are on the same workgroup. Would a network domain be considered the same thing?

4) How come my Linux boss name doesn't show up in my router's status? In the status box it lists the IPs and MAC addresses of all 3 computers on my network (2 Windows + 1 Linux) but the Linux machine's entry doesn't have a name, whereas the two Windows' computers do. This is not critical of course, I'm just curious why it wouldn't show up.
