[Asterisk-Users] Zaptel Compile on a virtual dedicated host.

Hi,

Do you happen to know what VPS system your host uses (e.g. UML,
Virtuozzo, VMWare, FreeVPS, etc.)? It could make a lot of difference, as
some platforms will allow changes that others will not.

Giles thank you for getting back so quickly, "dmesg" doesn't output
anything, but even if it did, I am not sure that I could recompile the
kernel.  
 
The server I am using is in a virtual dedicated hosting environment, I
do not have access to recompile the kernel, nor can I replace it. The
server prevents me from doing so.  I do not have access to the "real"
/boot and don't have access as far as I can tell to the .config for the
kernel source. ("make oldconfig" seems to work)
 
After a few more days of tech support, google searches and etc, I have
found that my provider is using kernel 2.24.21.4.0.1.elsmp.  Of course,
cat /proc/version doesn't think so!!  It thinks I am running Kernel
2.4.20-021stab022.11.777-enterprise.  I am able to use rpmfind to source
the corresponding rpm which installs without incident.  The interesting
part is "rpm -qa kernel" doesn't see it :-(.  I even tried to "rpm
-rebuilddb"

Zaptel appears to compile fine, but when I run "modprobe zaptel" I get
the following:

---->
/lib/modules/2.4.20-021stab022.11.777-enterprise/misc/zaptel.o:
kernel-module version mismatch
       /lib/modules/2.4.20-021stab022.11.777-enterprise/misc/zaptel.o
was compiled for kernel version 2.4.21-4.0.1.EL
        while this kernel is version 2.4.20-021stab022.11.777-enterp.
/lib/modules/2.4.20-021stab022.11.777-enterprise/misc/zaptel.o: insmod
/lib/modules/2.4.20-021stab022.11.777-enterprise/misc/zaptel.o failed
/lib/modules/2.4.20-021stab022.11.777-enterprise/misc/zaptel.o: insmod
zaptel failed
<---

Is there a way to override zaptel's kernel check or have linux fool it
into thinking the kernel is 2.4.21-4.0.1.EL?
 
thanks!

You could always download the Vanilla kernel source from
http://www.kernel.org and compile a kernel from source. I tend to always
use the Vanilla source, it's what everything has been tested against and
it tastes better.

You should probably print out the "dmesg" output to help you configure
the kernel options prior to compilation so that your "hardware" is
correctly detected.

I would also urge you to use a bootloader such as grub or lilo to ensure
that you can revert to the original kernel should it panic on boot, I
suspect Redhat already uses one of those anyway.
