Auth reask

nenel

Hello,

I've successfully setup a working client of OpenVPN on DNS-320 (arm architecture) under Debian.

It's starting correctly from the command line (openvpn --config /etc/openvpn/xxxx.conf), from the init script when I'm connected to the box, using auth-user-pass method and initiating the connection correctly.

However, I noticed it stops functionning after a while, so I've launched it under "screen -L openvpn --config /etc/openvpn/xxxx.conf" with 'verb 4' to have a trace (btw, it does not log to /var/log/syslog, but that's another issue imho).

The log shows that it "stops" functionning a short while after I've disconnected my ssh session; actually it asks after a while (no timestamp in the message) for authentication whereas the auth-user-pass is been working correctly on initial startup and then, of course, fails to reconnect to the server properly.

The tun module was compiled it by myself on the box, but it is still there so I assume the tun module does not crash. Restarting by hand the client allows the tunnel to be established, so no hung can be proved from that side (at least!).

Have I missed any configuration option, or something else (lack of entropy, tty related-stuff)?

Many thanks for your help

Try adding

daemon
syslog

this will cause openvpn to daemonize itself and to write all output to syslog ; you can supply an optional name to both (e.g. 'syslog openvpn').

Thanks for the quick reply, ok, trying that... (syslog appeared again, thx !)

Part of this code was provided by my OpenVpn provider, so dunno the side effect of every option (this is my first try...), neither if some are only optional. Probably worth a try ! 😃

depends a bit on the server setup, but this client setup is never going to work. try

# Which device
dev tun
fast-io

persist-key
persist-tun

nobind
remote xxx.xxxxxxxxx.com 1194

client
comp-lzo

cert /etc/openvpn/client.crt

Many thanks, working wonderfully since the change for ~24h !

Keep up the good work 🙂
