I'm trying to connect to an ISP. They have given me a username and password. I'm using Linux rEDHAT 6.1. I've setup the PPP connection OK.
The problem is that CHAP authentication always fails.

In /etc/ppp/chat-secrets, what do I put in the 'secret' field ? I tried the password but NO-GO !!

I can connect using PAP no problem

Very few ISPs support CHAP (I've never heard of one that did) and you generally won't be able to connect if you use it.

kiffney is right on... I've never heard of an ISP using CHAP for ordinary dialup. You need to change to PAP authentication.

I am using CHAP with an ISDN connection. I don't know if the options for ppp are the same for ippp, but I think they can be usefull for you.

I have an options.ippp0 file. Here I choose between CHAP and PAP. For CHAP I add a line:
      name username
For PAP I add a line:
      user username@xxxxx

chap secrets file:
      username   server     password
      server       username    password
