Description: I have upgraded from Red Hat 5.2 to 6.1. After that ppp connection still worked until i updated all available packages using Update Agent several times. After last update ppp stopped to work: I worked to isolate the problem to single package and it is: initscripts-4.68-1.i386.rpm I installed the prev. version - initscripts-4.63-1.i386.rpm - and after rebooting the system ppp worked properly. I installed back latest version - initscripts-4.68-1.i386.rpm - and ppp das not want to work at all. When starting ppp directly by /usr/sbin/pppd response is: [root@localhost atanas]# /usr/sbin/pppd /usr/sbin/pppd: The remote system is required to authenticate itself but I /usr/sbin/pppd: couldn't find any suitable secret (password) for it to use to do so.
I have the same problem with the new initscripts, except my system is a clean 6.1 install rather than an upgrade.
Workaround for this which did it for me: Add 'noauth' to your /etc/ppp/options file.
