Be careful, that's not because you are using the callin option that you
have to disable the ppp auth on the other side.
There is a one way authentication but there is authentication
R1 (with callin) calls R2, R2 challenges R1 with R2 as hostname (but R1
does not challenge R2), R1 checks its local database to see the password
associated with R2, encrypts the password and challenge with md5 and send
it back to R2 with R1 as hostname
R2 checks its local database to see the password associated with R1,
encrypts it (and challenge) with md5 and makes a comparison with the one
sent by R1.
If there is a match, authentication occurs and the layer 3 is up.

Objet : RE: ppp auth chap callin
I tried to ping from the router that has ppp auth chap callin and i removed
the ppp auth from the other router,
the result was as follow:
1st channel connected without auth as if its true [no authe for the
output calls] treating th ecall as outgoing
Then channel 2 treated the call as callin and auth failed!!!
any idea y the second chanel treated the call as incomming call?
even after i removed the ppp multi from both sides same result
any idea

One thing more in the isdn, when i put this command into r1 : ppp auth
chap
callin the help says [Authenticate remote on incoming call only], I cant
understand that,it implies that it wont ask for authentication for the
outgoing calls, is the calling router the one who asking for the
authentication or the called router?
thx

Use that when you want to use a password other than the hostname for the
challenge
