We've noticed a strange phenomenon on our HiPers used for dial-in: It seems (this may not be true, though) that suddenly the hipers will not authenticate older Macs (using MacPPP/ConfigPPP), older Windows (Winsock), or even HyperTerminal logins. The log (We use Cistron Radius on a RHLinux 6.1 box for authentication and accounting) shows the username fine, but the password is garbled (garbage characters), and thus can not authenticate. The Hipers are all running 2.0.51 (Which, BTW, really helped the problems with losing modems), and they have been hardware reset.
From telnet, the SHOW PPP gives a Dial-in Users Authenticate set to "ANY". I have used SET to change this to the other settings and back again.
Our Quads which authenticate on the same box are unaffected. The only recent change unique to the hiper chassis is it was switched to a new backbone provider and now has all new IP's. There are no other problems-everyone else can connect fine Other PPP (Mac and PC) are fine, only older PPP programs have problems.
