I'm looking for implementations of ppp, the most interesting for me being the mips/ultrix one. Can you help me with indications of possible sources ?
Probably the best PPP implementation for Unix available is the commercial package from Morningstar Technologies. ftp.morningstar.com provides information about the package (including the user manual in postscript format) and they can be reached at <marketing@morningstar.com>. They support large variety of Unixes (including Ultrix) and the pricing is around $800. Their PPP support all the current official and draft features and also VJ-SLIP. ftp.uu.net:/networking/ip/ppp is a good source for several public domain PPP packages. Including packages such as dp.2.0 (PPP with dial-up support) and pppd-1.01beta (Sun streams PPP). For Ultrix I certainly would recommend MST PPP. Petri
