ERROR: Cannot ioctl TUNSETIFF tap0: Invalid argument (errno=22)
Posted: Wed Dec 20, 2023 8:40 pm
i am trying to bring up what used to be a working config, and am running into an issue. i am starting openvpn and it fails with the error:
ERROR: Cannot ioctl TUNSETIFF tap0: Invalid argument (errno=22)
the os is fedora 38, fully updated, and i have systemd-networkd configure the bridge and tap0 interfaces. i have an up and down script, but i dont think they are needed. is there anything i am missing or doing wrong in the configs?
