Hi again It's been about 3 weeks since installing Linux and everything's been going smoothly.

I use my computer for running 1 eggdrop and 1 psyBNC 24/7. The thing is, I really would like to be able to give my eggdrop a vhost, but I don't understand anything about vhosts, nameservers, reverse DNS and all that...

I think the first step is to register a domain name, right? I've done that before, I can handle that.

I just have no clue where I would go from there, I've never done anything like this before. I keep searching the web and this forum for 'vhost' and stuff but I just get results which I can't understand. I think I need a simple tutorial that explains the basics, or a brief explanation of the basics to get me going.

I am just really confused (again).

The Linux Documentation Project - Networking HOWTO
http://www.tldp.org/HOWTO/HOWTO-INDEX/networking.html

Well, I've read the DNS section of that tutorial quite a few times since you posted it. It's too advanced and it doesn't explain the basics, it assumes you know quite a bit

So far I registered swinger.homeunix.com (dynDNS) and made it resolve back to my real IP address.
I want to be able to go on IRC with that domain. I know it can be done because I see other people online from the *.homeunix.com domain and from many other free domains that dynDNS lets you register, like *.is-a-geek.com

Once I get it working with that swinger.homeunix.com I will register my own domain and use that for IRC. At the moment I don't know what I have to do my end to get it to work

I know I have hosts and host.conf and many others which I probably have to change to get this to work, but I don't know what to change them to. Whenever I do a search for "virtual host" or whatever, only instructions about setting up Apache with virtual hosts comes up, and that tutorial you posted is way too complex

most of the vhosts that the people have are given out BY the actually ircD so wouldnt it be easier to ask in #vhosts.
To get ure own linux box to act as any type of vhost or hostmask u would need to have the program running on ure PC and then connect to it via a host pc like n eggdrop etc.
set ure linux box up to run n IRCD then u can assign any vhost u need to
linode.com have all ure answers its a linux forum far more into actuall irc than this forum is laid out to do.
have fun I got my dns reversed
although some IRC servers will reject it until they've caught up with the changes too!
so most of the time the ircd u joined will not allow it
have fun
