[LON-CAPA-admin] new install config help

[Robert Lance Mock]

I accidentally sent original message from wrong email address so if you get 
a message similar to this one later, I apologize. 

Just did a fresh install of FC3 and loncapa 1.3.1 on new machine. 

Went through entire install successfully while plugged into my school's 
network.  Used an i.p. address I made up. 

Successfully able to surf to it from other network machines. 

NOT able to log in at the welcome screen; it goes to a "page not found" 
error.  Also not able to surf to it from my house (off school's network). 

I'd like to avoid contacting my school's network guy, since when I told him 
about this project, he just said "go do it".  My impression was that I'm on 
my own. 

Where did I likely make my error(s)? 

Lastly, what's the best way to search the archives?  Dowload and do text 
searches? 

thanks,  rob
