Chap in SCO ppp
I have an example of configuring non-CHAP ppp at Quick PPP setup.
I'd almost forgotten what it was like to work with dial up Internet access. Reading this post brought back memories.
It's not as bad as it might sound - the Internet was 99.99% text then and for most business use, email was almost all of the traffic - maybe a patch download or two mixed in.

SCO PPP: Add "name=<username>" to /etc/ppphosts. Add "<name> <password>" to /etc/pppauth (or with some ISPs, including MCI and ATT/Worldnet, you need to put in a wildcard name, "* <password>"). That's all you have to do; CHAP will be turned on by the ISP during initial negotiation. MST PPP: Almost the same. Add "name <username>" to /usr/lib/mstppp/Autostart. Add "<name> <password>" or "* <password>" to /usr/lib/mstppp/Auth. IMPORTANT NOTE: Some NT RAS systems will require not just CHAP, but Microsoft CHAP, which is similar but uses a different encryption/hashing algorithm. SCO PPP does not support that protocol yet (but it will in 5.0.6). MST PPP supports it already. So if the ISP requires Microsft CHAP, you will have to use MST PPP, and you will probably have to use the "* <password>" form for your Auth file, on account of NT does stupid things with the name field in MS-CHAP challenges. -- Evan Hunt - evanh at sco dot com "The only thing better than normal, everyday spam is spam from the Lord." - Jason Abbott From - Tue Jan 11 15:22:33 2000 From: Richard Seeder <email@example.com> Newsgroups: comp.unix.sco.misc Subject: Re: Only 10% success rate in dialup ISP connection Date: Tue, 11 Jan 2000 09:40:10 -0600 Message-ID: <387B4EDA.AB03DA28@worldnet.att.net> RP wrote: > > The ISP (ATT) requires PAP authorization, no chat script.

The problem is that Worldnet individually identifies each modem, so using a specific name would get you in only when you happened to connect to that particular modem. The solution is to use a wildcard (*) as the system name in the auth file, so it doesn't matter what modem you get. Worldnet's own software, run from Win9x, automatically deals with this, so it connects OK. Kind of sounds like what you're seeing, but ymmv. -- Richard Seeder firstname.lastname@example.org
