PPP package errors ( installing USB DSL Modem)
 

Hello ,

Have managed to obtain a copy of drivers for my USB DSL modem ( dynamode A360)
Using RH 7.2 btw.

drivers include ADSL-PPPOA-1.0-1.i386.rpm which I have installed .
have edited kernel & have required options .
Have installed ppp-2.4.1-2.i386.rpm also

Install script is not running to completion , error log is as below :
relates to package ADSL-USB-PPP-1.0-1

Start of logifile :
installing the module for kernel 2.4.x
modprobe failed to load the module ppp
Uninstall the incomplete package with command: rpm -e --noscripts ADSL-USB-PPP-1.0-1

Please help ,

Really pleased with RH Linux however is a non started without internet access .

Hi,

Looks like a module version information problem.

You are trying to load a kernel module which was compiled for a kernel with "symbols version information". Your kernel doesn't seem to export this version information, or you are using a different kernel version. You can test this like this:

cat /proc/ksyms | grep dev_close

You should get something like this:

<address> dev_close_R<version>.

The <version> part should be "b323e7fb" (Your ppp_generic.o module needs "dev_close_Rb323e7fb"). If the numbers don't match, you are using a module with a different version than your kernel. If you don't get a <version> part at all, you must check your kernel config: "Loadable module support" --> "Set version information on all module symbols" should be "yes". If not change it and recompile your kernel and modules.

Hope this helps...
Giovanni.

Thanks for your suggestion :

ran cat /proc/ksyms returned different value to requied value

ppp_generic.o module needs "dev_close_Rb323e7fb

Have installed both ppp-2.4.0.tar & ppp-2.4.1.tar still have same problem

i'm using kernel 2.4.7-10 btw

what ppp tar should i be installing ?

can't remember value returned from cat /proc/ksyms & have not currently got time ( tired) to swap disc re-run then swap disc back to post on windows ! however if you need this info i will post it .

Many thanks Steve

Note: ppp in Linux = kernel modules (ppp_generic.o, pppoatm.o, ... in /lib/modules/...) + ppp user space programs ppp-2.4.x... (/usr/sbin/pppd, pppoatm.so plug-in, ...)

I think your kernel version is too old. I am not sure about this, but I believe you need at least 2.4.19 for pppoa. (But maybe RH patched its kernel?). Try to upgrade your kernel. I am using 2.4.20. Your ppp version is probably ok. BTW I am using ppp-2.4.2b3 + the pppoa patch for this version.

Good Luck!

Hi ,

Still working on it !!!

Installed kernel version 2.4.22 still receiving same errors as before ,

Reinstalled RH7.2 again from scratch kernel version 2.4.7-10 , edited kernel to allow ppp support etc

received different logfiles errors when running install script:

installing the module for kernel 2.4.x
modprobe failed to load the module ppp
Uninstall the incomplete package with command: rpm -e --noscripts ADSL-USB-PPP-1.0-1
slhc.o: kernel-module version mismatch
slhc.o was compiled for kernel version 2.4.7-10
while this kernel is version 2.4.7-10custom.
ppp_generic.o: kernel-module version mismatch
ppp_generic.o was compiled for kernel version 2.4.7-10
while this kernel is version 2.4.7-10custom.
ppp_async.o: kernel-module version mismatch
ppp_async.o was compiled for kernel version 2.4.7-10
while this kernel is version 2.4.7-10custom.

Have received this email from modem company Dynamode :

RedHat Linux 7.2 has been tested

Dynamode do not support Linux however every effort will be made if required to assist with device related problems (not Linux kernel configs)

Please help

Regards Steve

just a thought

error states that

ppp_async.o was compiled for kernel version 2.4.7-10
while this kernel is version 2.4.7-10custom.


looked in /usr/src

there is no mention of 2.4.7.10custom ??????

please help .....

I don't get it... Can I have some more information?

When you install the driver, does it overwrite the kernel modules (in /lib/modules/<kernel-version>/kernel/drivers/net, etc...)?
When you reinstalled your kernel, did you recompile it, or just installed it?, Did you compile and install the modules (make modules && make modules_install)?
Where can I find the driver you are trying to install? Do you have the source code of it?
