Re: ppp authenticaion

who can help me ?


Re: ppp authenticaion

There are two things to look at here. When you dial in using a terminal window to manually enter your username and password this uses "aaa authentication login". When you dial in using no terminal window and just let dialup networkin make the connection this uses "aaa authentication ppp".

Keepin this in mind when you dialin with your terminal window your "aaa authen login" method probably does not have the user name and pass you are typing in to authenticate the user. The best way to check would be to run the followin debugs

debug aaa authen

debug modem csm

debug modem

debug ppp neg

I would suggest just sticking to one method of dialin connectivity (terminal window, dialup networking) that way you don't have to have the user ID's in more than one place.

Re: ppp authenticaion

i add the following command:

aaa authentication login mobile radius

line 1 120

login authentication mobile

when i use terminal window,the username/password can pass.

but after the terminal window it seems going to ppp authetication.Then fails.

that means when i use terminal window,i can't use "ppp authentication pap mobile" on "interface Group-Async0"?????

on this,if a user that i don't know dials in with dialup netwoking,he can pass without authentication.

why? how can i authenticate a user with two method(terminal window,dialup networking)


Re: ppp authenticaion

Under the lines can you please add "login authentication adm"

Thanks, Mak.
