berder 0 Posted ... (edited) Hi, This is my first attempt at running a VPN client. My OS is Slackware 14.2, so I downloaded the Linux CLI client tar.gz, but it fails to connect to any server. Trying the AppImage didn't help. I noticed that if I use the "-connect" option or don't wait long enough (about 30 seconds I guess), then the client freezes on "Waiting for latency tests" and never attempts to actually connect to a server. Anyway, if I wait long enough for the latency tests to finish in background without printing the "Waiting for latency tests" message, the client tries to connect but fails on a network interface error, and then tries again on another server, and again, without ever succeeding. Here is an example log (until it attempts the second connection) : $ sudo ./eddie-cli profile=AirVPN_Europe_UDP-443.ovpn -login=foo -password=bar . 2020.04.26 00:05:23 - Eddie version: 2.18.9 / linux_x64, System: Linux, Name: Welcome to \s \r (\l), Version: Linux deepthought 4.4.190 #1 SMP Mon Aug 26 15:57:46 CDT 2019 x86_64 Intel(R) Core(TM) i3-2120 CPU @ 3.30GHz GenuineIntel GNU/Linux, Mono/.Net: 5.10.0.140 (tarball Sat Feb 24 15:30:44 UTC 2018); Framework: v4.0.30319 . 2020.04.26 00:05:23 - Command line arguments (4): path="/opt/eddie-cli/" profile="AirVPN_Europe_UDP-443.ovpn" login="foo" password="bar" . 2020.04.26 00:05:23 - Raise system privileges . 2020.04.26 00:05:25 - Profile path: /opt/eddie-cli//AirVPN_Europe_UDP-443.ovpn.profile . 2020.04.26 00:05:25 - Reading options from /opt/eddie-cli//AirVPN_Europe_UDP-443.ovpn.profile . 2020.04.26 00:05:26 - Tun Driver - /dev/net/tun . 2020.04.26 00:05:26 - OpenVPN - Version: 2.4.8 - OpenSSL 1.1.0l 10 Sep 2019, LZO 2.10 (/opt/eddie-cli/bundle/openvpn) . 2020.04.26 00:05:26 - SSH - Version: OpenSSH_7.4p1, OpenSSL 1.0.2s 28 May 2019 (/usr/bin/ssh) . 2020.04.26 00:05:26 - SSL - Version: stunnel 5.40 (/opt/eddie-cli/bundle/stunnel) . 2020.04.26 00:05:26 - curl - Version: 7.65.3 (/usr/bin/curl) I 2020.04.26 00:05:26 - Press 'X' to Cancel, 'N' to connect/reconnect to the best available server.

Edit : @giganerd (sorry to reply here but it seems I reached the maximum number of post per day, i.e. 1…) : thanks for the reply. Actually I realized after posting that there were other clients available, and it seems to work with "openvpn" (I'm not sure I understand why "eddie-cli" requires login when "openvpn" works without login, but I guess it's another story…).

OpenSourcerer 1360 Posted ... (edited) Do you have IPv6 connectivity? Ah, forget it, it's late. Now it'd be very nice to have something like a support file, but I don't see an option to generate one from the command line. advanced.expert comes closest to it, it seems to enable verbose logging. Not sure if it's really that. Anyway, I'd disable IPv6 and see if it can connect without it. Edited ... by giganerd I've not read ifconfig outputs for quite some time now, it seems, so I overlooked the v6 info in there :) Quote Hide OpenSourcerer's signature Hide all signatures NOT AN AIRVPN TEAM MEMBER.
