Amazon linux install openvpn3-client & dependencies as per
https://github.com/OpenVPN/openvpn3-linux
See the instructions on
https://community.openvpn.net/openvpn/wiki/OpenVPN3Linux how to
install pre-built OpenVPN 3 Linux packages on Debian, Ubuntu, Fedora,
Red Hat Enterprise Linux, CentOS and Scientific Linux.
1 solution was to switch from AWS Linux (lack of dependencies & updates) to Fedora on AWS. No longer have to build from source / add dependancices,
older versions had to add the repo as per the above.
When I did an upgrade to Fedora 36 the latest openvpn3-linux v18 client was built in. Did not have to manually upgrade / install it:
openvpn3-admin version --services
e.g: previous v17 suddenly stopped working spend 10 hours trying to debug
"Trying to install openvpn3-client" and reinstall:
openvpn3 config-import --config profile.udp.ovpn --persistent
openvpn3 config-manage --config profile.udp.ovpn --enable-legacy-algorithms true --show
openvpn3 session-start --config profile.udp.ovpn
openvpn3 sessions-list
openvpn3 session-manage --config profile.udp.ovpn --disconnect
Actually thinking it was a cipher AES-256-CBC
legacy issue that others were having. It was not for some reason, permissions on install of the OpenVPN3 Linux client? as it was NOT creating a TUN.
So I made one myself (that was the actual issue) and it connected after asking for VPN Username & Password, no need to install again / reinstall afterall:
sudo ip tuntap add name tun0 mode tun
sudo ip link show
