need help: /dev/net/tun
God,I'm newer to linux and don't want to reinstall my linux.
Currently we run a pragram(based on wireless mesh network) which needs the /dev/net/tun.
The linux system is Debian Sarge,with kernel 2.6.11.
I enabled the modules about TUN when I built this kernel and in the config file it's ok: CONFIG_TUN=m.
However, on the system,there is no such device. My partners have the same setting,and they all got that device.
How can I fix the problem? really need your suggestion.
