Hi, not sure ports@ is the best place for that, but either mlvpn doesn't work anymore or I made something wrong (I guess it's the latter).
I'm trying to make a mlvpn tunnel and it refuses to start on both side (server and client) with the exact same issue. mlvpn doesn't ship with specific instructions so I guess default install should work. Server is running 6.6 and client -current this is the client configuration, but the server configuration is quite identical. [general] statuscommand = "/etc/mlvpn/mlvpn_updown.sh" mode = "client" ip4 = "10.42.43.1/30" ip4_gateway = "10.42.43.2" ip4_routes = "192.168.1.0/24" mtu = 1444 tuntap = "tun" #linux only interface_name = "tunnel0" timeout = 30 password = "XXXXXXXXXX" cleartext_data = 0 [dsl1] bindhost = "192.168.1.31" remotehost = "perso.pw" remoteport = 5080 myawesomepony$ mlvpn -u _mlvpn -c mlvpn.conf --debug -vvvv 2019-11-28T09:46:10 [ DBG] absolute maximum mtu: 1444 2019-11-28T09:46:10 [INFO/config] new password set 2019-11-28T09:46:10 [INFO/config] dsl1 tunnel added 2019-11-28T09:46:10 [INFO] dsl1 bind to 192.168.1.31 2019-11-28T09:46:10 [ DBG/protocol] dsl1 mlvpn_rtun_challenge_send mlvpn: ioctl(TUNSIFMODE): Invalid argument mlvpn: ioctl(TUNSIFMODE): Invalid argument mlvpn: ioctl(TUNSIFMODE): Invalid argument mlvpn: ioctl(TUNSIFMODE): Invalid argument mlvpn: ioctl(TUNSIFMODE): Invalid argument mlvpn: ioctl(TUNSIFMODE): Invalid argument mlvpn: ioctl(TUNSIFMODE): Invalid argument mlvpn: ioctl(TUNSIFMODE): Invalid argument mlvpn: ioctl(TUNSIFMODE): Invalid argument mlvpn: ioctl(TUNSIFMODE): Invalid argument mlvpn: ioctl(TUNSIFMODE): Invalid argument mlvpn: ioctl(TUNSIFMODE): Invalid argument mlvpn: ioctl(TUNSIFMODE): Invalid argument mlvpn: ioctl(TUNSIFMODE): Invalid argument mlvpn: ioctl(TUNSIFMODE): Invalid argument mlvpn: ioctl(TUNSIFMODE): Invalid argument mlvpn: ioctl(TUNSIFMODE): Invalid argument mlvpn: ioctl(TUNSIFMODE): Invalid argument mlvpn: ioctl(TUNSIFMODE): Invalid argument mlvpn: ioctl(TUNSIFMODE): Invalid argument mlvpn: ioctl(TUNSIFMODE): Invalid argument mlvpn: ioctl(TUNSIFMODE): Invalid argument mlvpn: ioctl(TUNSIFMODE): Invalid argument mlvpn: ioctl(TUNSIFMODE): Invalid argument mlvpn: ioctl(TUNSIFMODE): Invalid argument mlvpn: ioctl(TUNSIFMODE): Invalid argument 2019-11-28T09:46:10 [WARN/tuntap] unable to open any /dev/tun0 to 32 read/write. please check permissions. 2019-11-28T09:46:10 [CRIT/fatal] cannot create tunnel device I tried `chown _mlvpn /dev/tun0` without success, I tried `ifconfig tun0 create` before starting mlvpn and still same issue. I use openvpn and tun on the client and it works fine.
