Hi all,
I am trying to connect to an ISP using my linux machine.  I am using
RedHat Linux 8.0 .  And the ppp version is 2.4.1.  I am not able to
understand why ISP is terminating the connection.  I have traced the PPP
packets and sequence is :
Serial connection established.
using channel 9
Using interface ppp0
Connect: ppp0 <--> /dev/ttyS0

ISP is expecting both PAP and CHAP authentication.  If PAP is
successful, then only CHAP authentication is requested.
What could be the reason for the termination.
Please give your comments.


With best regards,
