Tun/Tap Error.
 

Hi to everyone.

I`m try compile my TUN/TAP driver on Yellow Dog Linux.

But when i try load the module after a modules_install and reboot.

modprobe tun
i recive this error:

Can`t registry the misc device 200
FATAL: Error inserting tun (/lib/modules/2.6.27-1.ydl61.5custom/kernel/drivers/net/tun.ko): Device or resource busy

But when i try find where the file r in use i didn`t find anything.

on /dev/
din`t have any tun

but on /dev/net/

i got a file called tun

[root@localhost net]# ll
total 0
crw------- 1 root root 10, 200 Mar 15 00:16 tun


Sorry for bad english.
and Thx for now.

if you do an lsmod it'll probably show that the module is already loaded, which would give you the busy error

I alread think about that, but that`s the exist:

and the error persist

[root@localhost ~]# modprobe tun
FATAL: Error inserting tun (/lib/modules/2.6.27-1.ydl61.5custom/kernel/drivers/net/tun.ko): Device or resource busy

Is it possible that its compiled into the kernel? Try using the /dev/net/tun device

I format the machine and re-compile the kernel.

Until now, it`s all right.

So thx for help! :)
