hi,
a friend wants to connect to his office from his factory and other locations. In the old days I used to fit a dialup modem and he would dial in to his office machine - how is it done now? Do dialup modems still exist?
Just for knowledge sake, could you give some idea of how he would use the modem to dial into his office machine? What was the login type and how was the data accessed?
huh? This was in the 90s which was the way we communicated then - I forget exactly how we used to do it, but there were some scripts that would set the modem to receive calls and also dial out. So he dials in from his house modem to his office modem, there is a lot of handshaking and a ppp connection is established. Once that is there, all other methods like ssh, mail, http are available.
you setup a ras server on one end with autoanswer on the modem (ats0=1, atw). Then dial in from the other side. In the 80s we used ymodem/zmodem/kermit on dos. Afair kermit has all the stuff for point to point dialin.
Now you just use ppp - the same ppp that you use for dialout and the modem in auto answer. check the man page for ppp.
