Sorry about beating the dead horse. I need help to get this one down. What
is your choice in case you are asked to do "one way ppp authentication"? The
"debug ppp auth" result is at the bottom of each case, I know most people
would choose B, but I feel a little bit uneasy on mutual authentication
taking place when r2 calls r1:
A. r1 - ppp auth chap callback
r2 - ppp auth chap
result: r1 call r2 => r2 challenge r1
r2 call r1 => r2 challenge r1
----------------------------------------------
B. r1 - ppp auth chap callin
r2 - ppp auth chap
result: r1 call r2 => r2 challenge r1
r2 call r1 => mutual authentication
----------------------------------------------
C. r1 - ppp auth chap callin
r2 - ppp auth chap but r2 is not allowed to call r1
result: r1 call r2 => r2 challenge r1
----------------------------------------------
D. r1 - ppp auth chap callin
r2 - no ppp auth chap statement
result: r1 call r2 => no authentication
r2 call r1 => r1 challenge r2
-----------------------------------------------
Thanks,
Chang
