Scripts for Synology DSM
reconnect-vpn.sh
This script can be used as a workaround for Synology DSM's less-than-ideal reconnect behavior when a VPN connection is lost. The actual magic in this script was originally written by users on a thread on the Synology Forum. This script just provides a user-friendly wrapper to their code. For more information, including installation instructions, refer to my blog post.
As of version 1.1.0, extra customization options are included at the beginning of the script. Feel free to customize these to your liking.
As of version 1.2.0, the following exit codes are used:
0: reconnect not needed1: reconnect successful2: reconnect failed3: configuration error
As of version 1.3.0, an option is added to allow pinging a custom IP address or hostname to validate VPN connectivity.
As of version 1.4.0, an option is added to choose a specific VPN profile to reconnect, if multiple profiles exist. In this configuration, you could run multiple instances of this script, each targeting a specific VPN profile.
As of version x.x.x, an option to cause the Synology to beep and flash lights when the VPN is interrupted.
As of version x.x.x, an option for stopping/starting the Transmission Synology service and/or pausing/unpausing the Transmission Docker container when the VPN connection is disrupted.
