[root@Node /]# modprobe tun
[root@Node /]# lsmod | grep tun
tun 82432 6
Run the following command in Node:
[root@Node /]# vzctl set 101 --devnodes net/tun:rw --save
[root@Node /]# vzctl set 101 --devices c:10:200:rw --save
[root@Node /]# vzctl stop 101
[root@Node /]# vzctl set 101 --capability net_admin:on --save
[root@Node /]# vzctl start 101
[root@Node /]# vzctl exec 101 mkdir -p /dev/net
[root@Node /]# vzctl exec 101 chmod 600 /dev/net/tun
To check TUN/TAP is enabled or not :
[root@Node /]# vzctl enter 101
Inside the VPS:
[root@vps /]# cat /dev/net/tun
cat: /dev/net/tun: File descriptor in bad state # It means the TUN/TAP is enabled on your VPS.
cat: /dev/net/tun: No such device # If you receive like this, then the TUN/TAP has not enabled on your VPS . Try to enable TUN/TAP again and check.
- Enter mkdir -p /dev/net
- Enter mknod /dev/net/tun c 10 200
- Enter chmod 600 /dev/net/tun
- Enter cat /dev/net/tun to test whether the TUN/TAP device is available:
- If you receive the message cat: /dev/net/tun: File descriptor in bad state your TUN/TAP device is ready for use
