GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Built tb_userspace (gcc tb_userspace.c -l pthread -o tb_userspace)
2. Try and configure a tunnel (setsid ./tb_userspace tb 5.6.7.8 1.2.3.4 sit > 
/dev/null)

What version of the product are you using? On what operating system?
tb-tun_r18.tar.gz 
2.6.26-2-openvz-amd64

Please provide any additional information below.
Worked fine, rebooted my container and it's no longer working :(

@Davehope.co.uk ,
Have you checked your tun device? try 

:~# cat /dev/net/tun

and it should be

cat: /dev/net/tun: File descriptor in bad state

Or you can run other programs like

socat - tun:192.168.1.1/32,up

to test your tun device. If the same error occurs, the problem lies on tun/tap 
support of your OpenVZ platform, not tb_userspace.

Hi,

I believe this was because tb_userspace couldn't allocate enough memory. free 
-m showed 11mb, when increasing the amount of memory assigned to the container 
I've been unable to reproduce this problem again.

Thanks
