This is also what B.O.S. does, more or less. Bull's OSes initially treated IP/X25 (DDN/X25 more or less) as point to point links. B.O.S. now treats the X25 interface as a net through which you must route packets to reach the other machines... > B.O.S. does not support UDP/IP over X.25. > >That's odd. and untrue, as Frank Mayhar has already stated. Now for WHY one would like to use SLIP over an X25 link. I'll use my own situation as an example. I've got a Mac at home, a modem, and the software neccesary to use SLIP. I'd like to be able to connect to the machines at work from time to time, but all the access points are on TRANSPAC (the french national X25 carrier). Right now I use a terminal emulation program to log on, but I'd rather have an IP link. The major problem seems to be that B.O.S.'s X3/X29 interface uses one line-discipline, and SLIP uses another. Trying to use both blows my connection. Now I know that this is ugly, but wouldn't it be nice if it worked?
