TE412P and centos 4.4

i am struggling with the TE412P and cent os 4.4.

(1)libpri-1.2.2
(2)zaptel-1.2.3
(3)zaptel-1.2.3

These packages are a bit old because i am trying to duplicate an old system.


when i run /sbin/ztcfg, i always got the following error:
-----------------------
Notice: Configuration file is /etc/zaptel.conf
line 0: Unable to open master device '/dev/zap/ctl'

1 error(s) detected
-----------------------

I know it is related to udev of linux kernel 2.6.* . And also i read README.udev in zaptel-1.2.3 directory.

Unless i run following modprobe manually, the /dev/zap/.... files get created. But these files should be created automatically when rebooting (udev system's function)

$modprobe zaptel
$modprobe wct4xxp

Only after above manually loaded module, the os will create the /dev/zap/xxxx .

.... BAD experience.....
