sys0001@dircon.UUCP (sys0001) (10/03/89)
I have a couple of questions about crypt and passwords. Being in the UK, our Unix/Xenixes are delivered without the crypt system call. (I run Xenix 386 v 2.2.3). I'm thinking about replacing the supplied login program with one from USENET, and using a PD crypt library. The first question: would I be right in saying that password entries produced with a particular version of crypt, will be compatible with passwords entries produced with the same version of crypt on another machine (maybe with a different CPU)? What I'm concerned about is transfering users to a new system when we upgrade. I don't want to reissue loads of passwords, so I want to be able to somehow preserve the passwords between systems. Any information/comments about doing this would be appreciated. Finally, are password files from SCO Xenix and SCO UNIX compatible. ie can I directly copy the standard Xenix password file (with passwords based on the supplied passwd program) onto SCO UNIX and users will still be able to login? One last question. Does anyone know whether Yellow Pages will be available for SCO Xenix/UNIX? sys0001@dircon.UUCP (or ...ukc!dircon!sys0001).
