Hello All ! Some time ago I posted a "how to" question with the subject above, and didn't get any help. After a long and painfull research I found out the problem, and I would like to share this experience, so perhaps in the future this can save some time to someone. My final goal was to setup a PPP conection between a RedHat 5.0 Linux server and a ISP using WindowsNT 4.0 (glub!) over a leased line. The first step is carefully go thru all PPP setup procedure, as explained in the PPP-HOWTO documentation. As the ISP is running NT4.0, you must be sure to use MS-CHAP to allow Linux to authenticate on the NT Server, so add to you pap-secrets file the login information. (see example below). You may note there's no difference in setting up the Linux server for a dial connection but the chat file. The real problem is on the NT side. In order to configure a leased line connection, you must configure a standard modem as "Dial-Up Networking Serial Cable between 2 PCs". On NT 3.51 this used to be the "Null modem" option. The problem is this kind of modem only allows a Microsoft encrypted authentication, not compatible with any other system. In order to allow it to authenticate using a Linux compatible mode, you have to modify the modem.inf file on the NT server, as explained on articles Q122318 and Q150808, both available from www.microsoft.com. After doing the "setup" procedure described on those articles, the NT server will recognize a "$" string as the ppp connect string, and will authenticate the Linux box. I had a hard time convincing the ISP provider to make to modification on their side, but after a dozen reboots on the NT server everything was working fine... Good Luck !
