I have successfully chrooted Fedora among other distros in my Android but I've run in a problem I cannot overcome.

I am trying to use openvpn on a .ovpn file, however I am unable to open /dev/net/tun as I do not have permissions; presumably since my Android is not rooted, as I do not have this problem on my rooted phone.

Here is what I thought:

mknod /home/user/tun c 10 200

With this I could create a node as chroot and then use shoot openvpn --dev to use that one, however running the aforementioned command creates no node. I am not getting any errors, it just doesn't create a node. I cannot run mknod outside the chroot system as my Android is not rooted.

Are there any workarounds? Sorry if this is a trivial question, I am not very familiar with nodes. I tried other distros just for the sake of it but same error happens.

Thanks a million in advance.

  • I don't think you can just create another device node to make use of the tun driver. Neither is /dev/net/tun a tun interface. --dev is a way to specify the name that OpenVPN should create the tun (or tap) interface with. Commented Nov 22, 2023 at 15:29
  • Thanks a lot @TomYan for the answer. I tried openvpn --dev tun0 ./myfile.ovpn Options error: Unrecognized option or missing or extra parameter(s) in [CMD-LINE]:1: dev (2.4.11) Use --help for more information.. If you have any other ideas let me know, otherwise I guess it may be slightly impossible. Commented Nov 22, 2023 at 15:42
  • I think you are required to use --config path/to/ovpn, because path/to/ovpn is now not the only argument. Either way, --dev tun0 is not gonna help if openvpn can't open the "real" /dev/net/tun (that is, a device node that is actually bind to the tun kernel driver). (I'm not even sure if your mknod actually made a real character file at all, since it shouldn't be possible when the device is not rooted.) TL;DR, don't bother, it won't work. Use a proper Android OpenVPN client. Commented Nov 22, 2023 at 15:58
  • Android OpenVPN client works fine, wanted to see if I could only tunnel the distro though. Anyways, thanks. Commented Nov 22, 2023 at 16:32
