Dial-in Server

Hi all.

Setting up a ppp server is the ONLY thing I have never been able to do no matter what I try...

Here's what I've got at the moment:

/etc/inittab:

dude, how did you go ?

I'm trying to setup the same thing here.. noticed your post is getting old now, thought you might have had some success and could point me in the right direction...

hope you can

Yeah I _finally_ got it going.
I'm using pppd and mgetty comiled by Gentoo's ebuilds, so there's no need to mess with the compilation...

I had a LOT of trouble with authentication. I tried all options. This is what works for me:

/etc/ppp/options.server:

hey Dan,

I have set it up, but haven't had a chance to test it. I'll test it tomorrow from work

while I've got you though, I'd like to ask your advice.

I am setting up a linux server, and I wanted it to act as a fax server for sending and receiving, as an answering machine, and also as a dial in server for remote internet and file access.

I know mgetty+sendfax are bundled together, and there is also vgetty, but I think u can only use one or the other.

Can you use mgetty AND vgetty at the same time?

or is there someother way of of acomplishing this? or is it impossible!

many thanks

Chris

Whats the difference betwen the many versions of getty? Can I use agetty if a only want to access my server through a simple terminal?

try and see

agetty comes with the util-linux ebuild and its what gentoo uses for the virtual consoles, or at least on my compy.

To answer some of your questions.

The reason you use mgetty as apposed to the other getty programs is it is the only one that can reconise ppp data coming in and start ppp for that. It can also tell when a fax is coming in or when some one is dialing in with just a terminal program.

Also instead of needing to add the extra part on the end of this line in mgetty.conf
/AutoPPP/ - - /usr/sbin/pppd file /etc/ppp/options.server
move the options.server file to options.serialport
so it would be called
options.ttyS1 or options.tts.1 for Com port 2
depending on whether you have a devfs or not.

This way pppd knows where to find the setting for just that port. This allows you to easlly add modems to your dialin server.

Hope this helps

anyway to tell mgetty to answer on different types of rings?

like:

ring ring ring [pause] ring ring ring [pause]

or

ring [pause] ring ring [pause] ring

etc..?

and can it tell the difference between a data call and a fax call, and if it is data to start ppp, and if it is a fax to receive it?

dhunt · n00b Joined: 11 Oct 2003 Posts: 46 Location: New Zealand

Don't know about the specific ring sequences. I've never tried that. I know it has ring back support and pickup after X rings.

Yes it can tell the difference between a data connection and fax connection. Then if it is a data connection it looks for ppp packets and if it see's some it starts pppd.

If you want I can post some of my config files. That are working for faxing and ppp dialup as well.

taskara · Posted: Mon Dec 15, 2003 2:16 am Post subject:

that would be great.

I'd like it to pick up after 6 rings, and calls may be either data or fax... if fax, to receive, and if data to start Autoppp

I wonder how to get it to work with distinctive ring.. I may have to look up their webpage unless someone knows..

cheers!

Ok here's my configuration

/etc/inittab contains this
S1:345:respawn:/usr/sbin/mgetty -n 6 /dev/ttyS1

-n 6 means pickup after 6 rings

/etc/ppp/options.tts.1
192.168.0.1:192.168.0.20
proxyarp
idle 600
ms-dns 192.168.0.1
ms-wins 192.168.0.1
modem
crtscts
nodetach
asyncmap 0
auth
lock
debug
kdebug 1

I have devfs so that's why it is called options.tts.1 not options.ttyS1

/etc/ppp/pap-secrets contains the following line
* myservername "" *

/etc/mgetty+sendfax/login.conf contains the following line
/AutoPPP/ - a_ppp /usr/sbin/pppd auth -chap +pap login debug

/etc/mgetty+sendfax/faxlist contains
id
print HP
delete
/etc/mgetty+sendfax/new_fax
must be edited to setup where the fax modules are kept
for printing/emailing/forwarding etc.
These are all part of the scripts that come with mgetty.

Also the username/password used to authenticate with ppp
must be a user on the system with a password.
(i.e) useradd someuser; passwd someuser ....

Hope this help

Let me know if you need any more help

thanks for those

I have remote dial in working fine - it's the faxes that I'm not sure about.

I don't have this file: /etc/mgetty+sendfax/faxlist

do I just create it? does mgetty know to look for this particular file, or do I need to specify it somewhere?

could you give me a hand with the fax side of things?

also, mgetty logs to the console.. is there a way to change that to log to a file somewhere?

cheers

Ok for the logging side of things I had to make a directory
/var/log/mgetty
and then it will automatically write the log file in there

if you don't have faxlist you need to create it. It doesn't have to be in /etc/mgetty+sendfax but you must edit /etc/mgetty+sendfax/new_fax to setup where you have it. You may not have new_fax in your installation. It and the fax modules that you need are in the mgetty tarball under /sample/new_fax.all/

my new_fax file has at the top

# Do the settings here
home=/etc/mgetty+sendfax # The home directory
config=$home/faxlist # The configuration file
from="Fax Subsystem <faxadmin@xplor.ipf.de>" # From this user
log=/var/log/faxlog # logfile

This file must be in /etc/mgetty+sendfax.

Create faxlist as my other post. Each line except id in faxlist is a
module command. (I.E) print HP calls print.module to print the fax on HP printer. delete module deleted the fax. Other modules include archive and write. There is a sample faxlist in the tarball under /sample/new_fax.all/ which will give you some idea what you can do.

copy mgetty_tarball/sample/new_fax.all/*.module to the home directory you setup above. These are the modules I talked about above.

After that It should all work. Try receiving a fax! Let me know if you need anymore help

great thanks.. I've done all you suggested, and I'm about to try and recieve a fax.

one question though, my printer is currently broken so I took "delete" and "print HP" out of faxlist, but added "archive"

where exactly will it store the faxes?

also, is there a way to tell it to forward ALL faxes to my email, rather than storing on file - no matter who the sender is?

cheers!

hmm.. I asked my bro to send a fax, and mgetty answered, but didn't pick up that it was a fax - it seemed to think it was data.

is there a way to verify mgetty is auto diagnosing the type of call?

I changed my /etc/inittab to

Hi,

The best way to figure why it didn't pickup your fax is have a look in the log file /var/log/mgetty/mgetty.yourserialport. It should give some details there.

my archive.module says faxes are archived to /var/spool/fax/archive

to mgetty to email you all your faxes you would something like this in faxlist

id
email you@youremailserver.com
delete

This assumes that you have set up your email server on your computer properly.

For me to actually receive faxes properly I had to add the following to /etc/mgetty+sendfax/mgetty.conf
port ttyS1 <-- serial port modem is on
switchbd 19200 <-- just this line
init-chat "" ATS0=0V1Q0&D3&K3%C1W1L0M0 OK <-- this so I don't get blasted all the time

See if that works

Hey,

It looks your modem doesn't support faxing

or maybe needs some deferent initilization settings. Trying do a search on google see what you can find about it.

David

taskara · Posted: Wed Dec 17, 2003 3:40 am Post subject:

ok thanks David.

if I do find some initialization strings, where do I put them? under the port setting in mgetty.conf?

Thanks for your help.. I'll see how I go!

Hey,

Sorry I couldn't help you out more but if you do find anything for your modem, init strings go under the port settings in mgetty.conf

Good Luck

i am trying to setup a dialin server using a Vodafone 3G data card.
