Problem to connect the internet, Modem not found!
 

Hi!

I have some trouble making kppp work in kde.

On my laptop, the pcmia modem has been found but the tool bar will freeze after connection.

On my PC, the modem is not found. It has worked with another local version of Linux which was not that good and I have reinstalled red hat 9 over it. So I know that the modem works for linux. What can I do?

Also, how to give permission to access the internet to al users. A pop up keeps asking for root password for kppp.

Thanks for help.

:confused:

I dont really know anything about pcmia. On your PC, open a terminal and type: cat /proc/pci and post the output here. That should list the specific modem you are using so we know what driver you need for it.

Here is an interesting thread that deals with red hat. Both with kppp access as non-root user, and the modem not being detected. Check this out first :) http://www.linuxquestions.org/questi...pp+root+access

Thank you for the link and info:

1) Concerning access of kppp from a user account I tried this first:
**********************************************
Change the following line in the file /etc/pam.d/kppp from:
auth sufficient /lib/security/pam_rootok.so
to:
auth sufficient /lib/security/pam_permit.so
*************************************************
It worked but it gave root permission to the user to use kppp but also everything else, a little bit risky so I did not keep it.

2) The second and best solution for me is below:
***********************************************
When connecting to the Internet using KPPP, it will ask you for root's user name and password. There are three problems with this.

You may not want to give root's password to regular users.

You don't want the inconvenience

After entering roots password, and connecting, your panel is dead. With kppp being a console helper program, no matter which options (dock on panel, etc) were selected, it would overlay roots panel on top of the regular users control panel, making it essentially useless.

Red Hat chose to install kppp as a so-called consolehelper application. This PAM based mechanism avoids a setuid root installation. A quick and dirty solution to revert to the original behavior is to delete the link to consolehelper and make the real binary setuid root. Open a terminal window, su to root and enter the following commands:

rm /usr/bin/kppp
chmod u+s /usr/sbin/kppp
ln -s /usr/sbin/kppp /usr/bin/kppp
********************************************************
After doing this, kppp is accessible from a user account with no popup for root password, the panel does not die and it works.

I am posting all the detail in case that this can help someone with the same problem.

Concerning the modem not found,this is what I have after the command:

cat /proc/pci

In the previous linux system I had in etc/modem point to a file: ttySHSF0. But I am not able to copy the shortcut and file to transfer it on the new system (I still have one computer working on theold system).

Thanks for help.

Thats the info you need. Do 'lsmod' and post the output so we can see if any drivers are already loaded for that modem. If not, I saw plenty of sites that have a linux driver for that modem. Here's a good site I found about your modem: http://www.linuxant.com/drivers/hsf/...cb6ed711e9ea5a

Hi!

Thank you for all your help Scruff,

I will do the 'lsmod' thing on staurday when I access the computer.

Right now I have a computer that still have the old linux distro and modem driver installed. Is there a way I can copy it on disk and install it on my other computer? I tried to do this but it would not copy properly.

I have also the original distro disks and I wonder if there is a way I can extract the modem driver ttySHSF0 from there? ... without installing the os of course.

Thank you.

Michel

:newbie:

You should really just download the RPM and install it with that, or if your comfortable you can compile it from source. But I think for a simple modem driver an RPM would do the trick nicely. When it installs, it will likely place several different files in different places, so that might be why copying it didn't work. You would also have had to tell it to load the driver with 'modprobe drivername' then set it up to load at boot. An RPM should take care of all this for you.

Whats the name of the driver that works for you?

The modem driver is ttySHSF0

I know where to download it but the free version is only 14k. The 56k version is a paid version and I would like to be sure it works before buying.

:(

I see. I did a little searching, and it seems that others have had good luck with that driver and even link to the Linuxant site for obtaining the driver. http://mia.ece.uic.edu/~papers/volans/modem.html has decent instructions. I didn't see anywhere to get a free one either other than the 14.4k version you mentioned. However, if thats the route you're stuck with, you can be confident it will work from reading others success stories. Looks ok to me.

Thank you Scruff for your help.

First of all I tested the computer and got this about the modem:

That looks similar to the doc you directed me to.

I found on the disks of the previous Linux version this driver which was used and worked previously: hsflinmodem-5.03.27lnxtbeta03042700-1.i386.rpm

I tried an installation which appeared to start well but a problem occured at the end and the driver was not installed. Details of the commands:

**********************************************************

This package does not contain pre-built modules suitable for your system:
Distribution: RedHat-9
Kernel arch: i686

Trying to automatically re-compile the modules..
(this requires a C compiler and proper kernel sources to be installed)

Where is the linux source build directory that matches your running kernel?
[/lib/modules/2.4.20-8/build] exit

WARNING: missing file exit/include/linux/autoconf.h
The cause of this problem is usually a missing or misconfigured
kernel source tree (and sometimes an incorrect directory or symbolic link).

First, ensure that the proper kernel source and compiler packages
from your distribution vendor and/or the community are installed.

The Linux kernel can then be reconfigured by running "make menuconfig"
under the kernel source directory (usually /usr/src/linux).

Verify that the proper options for your system are selected,
and that CONFIG_SMP ("Symmetric multi-processing support" under
"Processor type and features") is disabled, as this driver is
presently designed to work on single-processor machines.

Then compile and install your new kernel (for more information about
this procedure, see the README file under the kernel source directory),
reboot the system using the new kernel, and re-run "hsfconfig".

***********************************************************
I do not understand what I have to do to fix the last part. Maybe a kernel problem between the old version of Linux and Red Hat 9 !!

I tried then to download the free version of the driver on the link you gave me (from Windows). After transfering the files to Linux the files have an extension of .rpm.zip . Installation did not work because it says it's not a valid RPM file. When I rename to get rid of the .zip , this says the same...

Well, no success for this time.

Thank you for any suggestion.

Michel

:mad:

First, you might try 'unzip filename.rpm.zip' to turn it into a straight .rpm and see if the newly downloaded file will work. It just might, and that would be the easiest route. Otherwise, it appears as if the install was prepared to compile itself for you when it asked for:
Where is the linux source build directory that matches your running kernel?
[/lib/modules/2.4.20-8/build] exit
and you typed exit there. Verify that /lib/modules/2.4.20-8/build exists on your system, then if you need to use that old rpm again, just hit enter when it gets to that point. If that directory does not exist, then you need to find out where your build directory is; usually /lib/modules/<kernel version here>/build and enter that path when prompted.

Give those a try and let me know how it goes :)

Check out this thread. This is how I got my HSF modem to work and it includes a link to the older modem driver (in tar.gz format) which is not speed locked to 14.4k.

On the same issue, I have a Presario 2540EA, with a connexant modem. I did get the Linuxant driver, it installed correctly, although Suse9 could not connect to the net via modem, I did get kppp to work on 2.4.19. Ever since I updated to 2.4.21-144-default, I have been having problems connecting to the net. (except via ethernet). Tried wvdial, ppp shell scripts, terminal, xplog, kppp and more. Well kppp now disconnects immediately with a pppd error 2, /var/log says invalid option pass to pppd passwordfd.so.
Terminal via kppp prompts me for user name and password from the isp, but I get the response authentication failed. The user name and password are valid as I can log on to the isp's site with the same password. I tried pap,chap and terminal.
Could there be some format that certain isp's look for in the user name and password which is oblivious to users on windows? As I did not have any problems with this isp since win 3.1 right upto 2.4.19 with kpp suse 9. Or am I looking in the wrong black hole?
btw, I have checked the man pages for ppp and kppp and could not deactivate the passwordfd option being passed to ppp yet. I even reach the password propt only via terminal or wvdial or ppp script. All else fails.
I have #'d out all the lines in all the files /etc that had the passwordfd line. my options files is empty. have tried distro independant versions of kppp, ppp, and wvdial. nothing on the suse site either. tried enough boolean searches on google too.
any clues guys? btw I am a newbie so kindly keep it in laymen terms.
thanks and cheers

I tried to fix the problem but without any sucess.

In the directory /lib/modules/2.4.20-8/ there is a file named "build", its icon looks like a lock-shortcut and the properties say that the file does not exist. Installation fails as usual.

I tried to create a directory "build" but a popup message says: </lib/modules/2.4.20-8/build is a file, but a directory is expected.>

I moved the build shortcut elsewere and created a new directory "build" hoping installation would work but it failed again...

There are also scary notes like asking for recompiling the kernel and so on... This is with the old previous driver.

I haven't tried the second version of the driver.

Any suggestion?

Thanks.

Michel

Hi!

After trying many time with the old and new driver (tar version) still no success.
It seemed to work with the tar version but at the end it says the same thing that there is a problem with the kernel and I have to recompile!!!

Scary...

I do not know what to do...

:(
