dial in to the system

sidra · 09-11-2007, 08:04 PM

Hi all,

I'm trying to get ppp set up. I DO NOT want to create a ppp network connection to dial to an ISP. I want my computer to be the host and be able to accept ppp connections from other computers. What do i need to do in order to establish this? Is a process supposed to run or does something have to be configured?

Thanks in advance!

Why would you need two phone lines? The OP doesn't state anything about needing to be able to have two simultaneous users connected. In any case, I think it's clear he understands the hardware needs. It sounds like he wants to know what to do regarding software.

well, forgive me if my knowledge is not that wide

but - i have no idea how can i dial into a system using PPP without the use of PPP capable device such as serial connection? maybe 2 modems and 2 lines way too much.

yes, PPPoE can do that, or,
do back-to-back cross-serial connection is ok,

the rest is using webmin|pptp server setup - much simple.

or maybe - you have better idea?
just my opinion.

HTH.

Notice how /dev/modem is just a link to the serial device on the box. It's the same principle as when you connect via dial-up to an ISP (the great majority of dial-up ISPs use PPP).

Without knowing how many simultaneous users sidra wants to have dialed-in, we don't know how many modems/lines he'll need. What we do know is that it'll be one per simultaeous user wanted. Either way, it's beside the point. You still need to setup the PPP dial-up server, which is what he is asking for help with.

PPPoE is way off-topic.

This is even further off-topic.

If I would have had something constructive to share with sidra about how to set up a PPP dial-up server I would have used my last post to share it. At this point, I ask that unless you have something that actually helps sidra setup his PPP dial-up server please refrain from posting. Otherwise, this thread will end-up cluttered with a bunch of off-topic posts.

Now, getting back on-topic: sidra, here's a few HOWTOs I found that might help you get started:

http://www.faqs.org/docs/Linux-HOWTO...TO.html#ss4.12

Is that the kind of information you are looking for?

Hi folks
I use this procedure to setup a simple dial-in server on Redhat 8.0, maybe it helps you:

I assume that an external modem is connected to COM1 also known as ttyS0.

1- Install mgetty and ppp if they aren't yet:

Code:

# rpm -ivh mgetty-1.1.28-9.i386.rpm
# rpm -ivh ppp-2.4.1-7.i386.rpm

2- Make a new file in /etc/ppp/peers/ named dialin :

Code:

# mkdir -p /etc/ppp/peers
# vi /etc/ppp/peers/dialin
  auth
  -chap
  +pap
  asyncmap 0
  netmask 255.255.255.0
  ms-dns 172.16.10.1
  proxyarp
  lock
  crtscts
  modem
  mtu 1500
  debug
  172.16.10.21:172.16.10.22

3- Add this line to /etc/inittab :

Code:

S0:2345:respawn:/sbin/mgetty -s 57600 -x 3 ttyS0

4- Add this line to /etc/mgetty+sendfax/login.config and comment out other lines that begin with /AutoPPP/ :

Code:

/AutoPPP/ - a_ppp /usr/sbin/pppd call dialin

5- Add username and password of calling user to /etc/ppp/pap-secrets :

Code:

"username"   *   "password"   172.16.10.22

6- Add an alias for ppp-compress-21 module to /etc/modules.conf :

Code:

alias ppp-compress-21 ppp_deflate

7- Reload /etc/inittab with this command :

Code:

# init q

Now everything is ready and you can dial in to your linux box.
Good Luck

I'm using a built in internal modem, it works just fine.

sidra · 09-14-2007, 12:23 PM

Yes, i'm using a PCI internal built in modem on my server. I just had to download and build the driver for the modem on it and then i was good to go with with dial-in server setup.

your modem make/model ?..i am trying it with Motorola smpci56 voice/fax/speakerphone...with no success

sidra · 09-14-2007, 06:12 PM

I have a "Conexant HSF 56k Data/Fax Modem" and yes you need 2 phone lines.
