Awhile back. before suffering a massive disk failure, I had NetBSD up and 
running connecting to my ISP with a PPP connection using chap 
authorization. Being the manly man type that I am [insert fool here] I 
never backed up my bookmarks on where I collected it from.

I know it was a collection of pppd scripts. One of them was called 
chap-secrets. If this rings a bell to anyone, please pass the url on to me.
