There are many ways to edit the config file.
However, from the way this thread is going, we need to get a few things straight.
First. I suggest you find yourself a beginers guide to shell access. These will give the basic commands, and how to navigate them, they will also usualy give you some don'ts to take point of.
Please don't ask where you can obtain one of these, as a simple search will find these for you. It's also an idea to looka t your providers help pages, and possibly other providers help pages.
Second. Read the setup guides on eggehlp.org - I have allready stated this within one of the replies.
See
THIS PAGE especialy, as it includes a guide to editing the config file.
99% of the problem with eggdrop, is that it's uses will not help themselves, and even when they are helped, unless the information is infront of there eyes when they read it, they wont follow the links or do the researched offered to them.
