Hello helpful people. I thought I'd ask early, this time, instead of making trouble for myself and _then_ asking how to get out of it. :-) 10.0 is installed. YaST Control Center > Network Services has 20 items in it, most of which I won't ever need. However, I will shortly be fooling with - Samba Server - Samba Client - Mail Transfer Agent I want to know what other stuff I should sort out _before_ I start meddling with the items above. For example, my LinkSys WRT54G is the house DHCP server, so my PC received its current address from the LinkSys (it's a 192.168 address, and I haven't checked exactly what it is today). Just for fun, though, I opened YaST Control Center > Network Services > DNS and Hostname. I got a message warning that dhcp stuff had already been supplied and I could either accept or modify... I accepted. In the dialog, my hostname is "linux" and domain is "site". Below that, the "Name Servers and Domain Search List" section is grayed out, but I can see that Name Servers 1 and 2 hold the IP addresses of servers at my ISP. Domain Search 1 holds the domain name of that ISP "magma.ca". I assume that this was all picked up automatically during the 10.0 installation/config process by YaST -- it looked for a dhcp server and the LinkSys said "this is what I've got". The remaining boxes are empty, except there's an X in the box beside "Update Name Servers and Search List via DHCP".... though that entire line is grayed out, too. NOW, keep in mind that I want to set up Samba and also a combination of fetchmail and IMAP (I think). What should I be doing, right now, in the "YaST Control Center > Network Services" dialog? I might like to have my box's hostname be "catbox". Given that I have not yet started any services or configured any servers (beyond what might have incidentally been started or configured during 10.0 installation), how pervasive is it going to be if make a change in "YaST Control Center > Network Services" right now? Also, should I leave the Domain Name setting as "site"? Should I change it to something? Right now, I'm browsing and getting/sending e-mail with this PC, so my network config seems to be working. I don't want to break anything. If I do change the contents of the Hostname or Domain Name fields, are those the settings that will be used/needed later when I setup Samba and MTA, and when I try to connect to them from another computer? It makes sense to me that that should be so, but I'm usually wrong when I make any assumptions about Linux or network stuff, so I'm asking _before_ I break everything horribly. Could there be anything already referring to the hostname "linux" and the domain name "site", and which I'll need to adjust it if I change either of those fields? Again, I have not yet deliberately configured Samba or MTA or anything else. It should all be "vanilla" as the 10.0 install made it. I know this is really, really basic stuff to ask, but I'm absolutely paranoid about breaking things (having found so many ways to do so - it's a talent). Thanks, Kevin
