Hi, I use Digi Embedded Yocto and I got this error message when connecting to OpenVPN server

ERROR: Cannot open TUN/TAP dev /dev/net/tun: No such file or directory (errno=2)

It’s like TUN/TAP is not included in the DEY kernel.

Can anyone help me?
Thank you

I do not believe TUN/TAP are included in default Linux Yocto kernel.
it should be along those lines described here:
