From: Lab Candidate (labccie@xxxxxxxxx)
Date: Sun Mar 24 2002 - 02:08:22 GMT-3
I logged on the rack today and redid everything, it just worked like a charm.
I still don't know what went wrong yesterday. Sean, I don't think the ppp
multilink matters in my case. to prove it, I configured it with and without,
and also configured one-sided, it all worked. This kind of situation and proble
m
is what I'm afraid most when it comes to lab date, which is this coming Thursda
y.
To all that are interested in solution, I pasted the final working config below
