Setting up dial up server on linux
 
Hey Guys
I am just wondering what all I need to setup linux dial up server. Because I am planning on using ubuntu 12.04.2 LTS and external 56k modem but what else I need to complete this?

Do you mean you want people to dial IN to your Ubuntu server, or you want to dial OUT?

For either, just plug in your modem. The device name is going to be needed. If it's a USB modem, chances are it'll be /dev/ttyUSB0. If you're using an old-style serial port, it's probably /dev/ttys0 or the like.

For dial-out, to an ISP:

For dial-in, you need mgetty:

There are many more documents you could easily find with a Google search, if you tried.

Ok, so read the second part of what I posted to you, with the name of the program to set up (mgetty, or Modem getty).

From that post, create /etc/init/ttyS1 (or 0, or whatever your device name is), with contents like this:
Code:
# ttyxxx - mgetty
#
# This service maintains a getty on tty1 from the point the system is
# started until it is shut down again.

start on stopped rc RUNLEVEL=[2345]
stop on runlevel [!2345]

respawn
exec /sbin/mgetty -D ttyxxx REPLACE the xxx with whatever your device name is
Again, this assumes that you've installed the mgetty software through your Ubuntu software manager. That will get you a dial-in connection. This isn't a dial-up TCP/IP connection, though, but a serial terminal. Do you mean you want SLIP working?

Alright so how would this work if you only got one number and you want 1 or more people to connect to it? just add more serial modems or what?

One phone number = one modem. Can't ever do more than that. If you want more than one person to log in, either person number 2 can wait until person number 1 logs off and disconnects, or you get more phone lines/modems.

If you need more modems, plug them in, give each one a phone line, and set them up as you did the first one, just put the different serial port info in.
