I did a quick locate:
[root at localhost ~]# locate chap
/etc/ppp/chap-secrets
/root/.kde/share/apps/RecentDocuments/chap_ms.h.desktop
/usr/share/slib/chap.scm
/usr/share/doc/HTML/en/kppp/chap.docbook
/usr/include/pppd/chap_ms.h
/usr/include/pppd/chap-new.h

I opened up the chap_ms.h file and it contains this line:
# client	server	secret			IP addresses

But what could my secret be? I don't know. Some more digging brought me to:
http://pptpclient.sourceforge.net/howto-diagnosis.phtml#chap_failure
http://pptpclient.sourceforge.net/howto-redhat.html

Where it suggests that I run:
[yoursys pptp]# pptp-command

Which I tried to find by:
[root at localhost ~]# locate -u
[root at localhost ~]# locate pptp-command
[root at localhost ~]#

With no luck. I also played around a bit with kppp which I discovered
1) exists, and 2) is installed on my system, however, I can't get it
to connect either- I can't even get it to contact the technion's
servers.

Thanks for all your help so far. I really, really, do appreciate Paul
and Kostass and Aleksander and everybody else who contributes to the
list.
