http://www.irchelp.org/irchelp/new2irc.html that will help you get started.

Just to let you know, 6667 and 7000 (normally ssl) are the port numbers, not the channel name.

Also you haven't told us what network you're trying to connect too and what client/OS you are using (e.g mirc or the much better xchat).

We need a bit more info before we can even begin to help.
