Re: Edwin, USA, kernel 3.0.0-12-generic

I do appreciate all the assistance you've given me, but it seems that what you're missing here is that I'm not going to be using the modem to connect to the internet with (kppp was only being used to check to see if the modem was responding to queries, it is not going to be used for any login sessions), I'm only going to be using it for sending and receiving fax transmissions. And as such it's imperative that I be able to access it as a normal user. This is not a computer that's in use by some huge commercial entity, it's a private in home computer that I use for personal use.

I've managed to gain access to it as a normal user by using a script to create a symbolic link between /dev/ttySM0 and /dev/modem, however I can't seem to get this script to initialize on system bootup, I have placed it in /etc/init.d and have marked it as executable, the contents of the script are as follows:

   #!/bin/sh -e
   #
   #Symbolic link for kppp
   #


   sudo ln -s /dev/ttySM0 /dev/modem

If I manually run the script as root after the system is up and running I have no problem accessing the modem as a normal user, but I'd prefer not to have to manually do this every time I want to access the modem. And please don't give me any lectures on security, Linux as most of us know full well is overly secured against letting normal desktop users do things they should be able to do (that level of security may be necessary in a corporate environment, but not generally in a home use environment such as the one I'm using this system in). In a situation where the system is in use by a home user there is no need for such paranoia usually. Users want to be able to actually use their system the way they want to use it, not have to worry about system permissions and file permissions and whatnot constantly.

Anyway again I thank you for helping me get the drivers compiled, I'm hoping someone can and is willing to help me get that script to properly run at bootup so that the modem is readily accessible to normal users.

As always thank you to anyone who can help,
Edwin

PPP  is considered a Security RIsk.
That is why Root/Adm permission is required to start a PPP connection.

Our general recommendation is to:
$ sudo modprobe martian_dev
$ sudo martian_modem
will setup the modem.  Then
$ sudo wvdialconf
will create a /etc/wvdial.conf  , which you can edit with:
$ sudo gedit /etc/wvdial.conf
removing the ;<   >  symbols as you put in your personal info.
Also add a line:
Carrier Check  =  no
---
This wvdialconf does not need to be repeated.
Start dialouts with:
$ sudo wvdial

If you have further problems, do write to the List.
We do strongly recommend that you get use to such manual usage, before
using graphical interfaces and changing permissions.

THANK YOU VERY MUCH, It compiled using the new Makefile and seems to run ok,
now I just need to get it configured to allow normal user account access to
the modem.  Running KPPP as root ('kdesudo kppp') and unchecking 'check for
dialtone' allows me to query the modem just fine.  Any chance of getting
some help setting it up for normal user access too now?  I greatly
appreciate all you've both done to help me.  I really don't want to have to
do all my faxing as root if I can avoid it. :)

The problem was an old kernel SUBLEVEL constraint, not cogent under

Edwin,

I don't get the errors that you are getting :(  I get WARNINGS, but
that is about it.  martian module is created see below:

[students@localhost martian-full-20100123]$ cat README
Martian is an alternative to the ltmodem and provides Linux support
for Agere WinModem hardware. Major difference is that core moved to
the user space.

Driver comprises two parts:
        martian_dev - kernel module to configure devices, and serve irqs
from it
        martian_modem - user mode application to supply major IO, buffers,
                user level streams.

For specific details concerning distribution and usage look in
directories.

When configuring wvdial add "Carrier Check = no" line. No modem status
is checked yet. Kernel mode part is linux-2.6 module.

Project has a sitehttp://martian.barrelsoutofbond.org/.
There is also maintenance within the Debian distribution
Athttp://www.debian.org/distrib/packages  ,  search with "martian" for
direction to the most recent code.

    Building

==================
   Installation
==================

In root directory run
$ su
# make install


==============
   Running
==============

Load module and run martian_modem first.
# modprobe martian_dev
# martian_modem [Options] [Tty]

Now Tty is the name of the device file to represent your modem. You'll
supply it to the dialer. /dev/ttySM0 if argument omitted. Left
martian_modem running and start the dialer.

See options available
# martian_modem --help


==============
     Auto
==============

In scripts/ directory run automate.sh.
$ cd scripts/
$ ./automate.sh

You can supply the option to be passed to martian_modem on loading like
$ ./automate --mode 0660

See ./automate.sh --help for more options.


==============
    Notes
==============

'martian_modem' program is a crucial part of the driver. It should be
running as long as you access the modem.

For technical reasons carrier status support is not available for the
modem client. Configure dialer respectively. For wvdial add "Check
Carrier = No" line to the configuration file.


x86_64 platform.
----------------

martian_modem is a 32-bit application. It can be built on x86_64 the
way prescribed, but you need 32-bit development environment for that.
Second option is to use binary built on i386.

To compile and install module only do
$ make -C kmodule/ modules
$ su
# make -C kmodule/ install

Edwin,

It could be a detection problem?  kernel 3.0.X is newer than 2.6.20,
2.6.39.X, etc.  Maybe martian code is not 3.X kernel friendly, I
thought that there could be error messages about some
things(functions) that have changed with the new kernel releases, but
the make command returns something different.  I will try to check up
on that and cc. to Marv in case he has some suggestions for you to try
out.

It's as if it isn't recognizing that my kernel is newer than 2.6.20, I
also
noticed in the ModemData.txt file that it doesn't seem to notice that
the
'linux-headers-3.0.0-12-generic' package is in fact already installed

I have tried searching on the Internet to find references on how to
correct
this problem but I can't seem to find anything relevant that I can
make
sense of.  So I'm turning to the Linmodems community in the hopes
that
somebody can help me figure this out.  Incidentally I'm also trying
to
install a similar modem into another computer, but I'll wait to see
what
I
learn here before I attempt to proceed further with the other system
(who
knows I may not need any help with that one once I get this one
figured
out
:) ).

Thanks for any help anyone can provide,
Edwin Barton
