bbs stops loading.

I am new to setting up G8BPQ software. And I am running linux (linBPQ).

I find now and than,  that when I go to bring up linbpq that the BBS portion doesnt want to load. Anymore.

It is probably because I have changed something,  so what I need to know is,  what actually brings the BBS up?

I know there are lots of thiings happening when you run ./linbpq  but what file actually starts the BBS. Or what file is the BBS?

This way if I mess things up again,  I will be able to fix whatever file is the BBS.

Sorry for any confusion here. But new at this and trying desperatly to get things to run..
