How can I find the local log files of my VPN client?
Safejumper on any OS
If you use Safejumper to connect to our tunnels, you can easily find the logs among the software options. On desktop, logs are usually available via "Logs" entry in the tray menu. On mobile, logs are accessible via the "Logs" tab. The most important log type for us is the OpenVPN process, but a copy of both the application logs and the OpenVPN process logs will increase chances of finding a prompt solution.
Third-party OpenVPN clients
Most of times, third-party OpenVPN clients do provide logs either via the software options or via a directory where it stores logs in the form of .log files. You should consult the documentation of the client you are using. For default OpenVPN GUI, the logs are usually available in the logs directory of your OpenVPN program files. For Tunnelblick, logs are available in the "VPN Details" entry in the tray menu. For Viscosity, logs are available in statistics window, if you click on the symbol that resembles to logs. For Linux OpenVPN client, it is usually in /etc/openvpn.
Built-in OpenVPN clients
Some operating systems such as Linux Ubuntu offer built-in OpenVPN clients and the logs are usually accessible around the same section as the OpenVPN tunnel configuration.
To get log information from your DD-WRT router, please go to the "Commands" page and run the following commands:
iptables -L -n -v
iptables -t nat -L -n -v
Also, enable "Syslogd" under "Services/Services" and enter "cat /tmp/var/log/messages" in the "Commands" page.
If you're experiencing any issues with your DD-WRT configuration and you're asking for help, you should include this logs.
