This is a Golang implementation of theOpenConnect VPN Protocol for client side development.
The released binaries contain a command line program(sslcon) and a VPN service agent(vpnagent), the latter of which should be run as a separate background service with root privileges, so that the front-end UI does not require an administrator authorization every time it starts.
The API is exposed through the WebSocket and JSON-RPC 2.0 protocols, so developers can easily customize a graphical interface that meets their needs.
There is a GUI client example showing how to use this project.
Currently the following servers are supported,
$ ./sslconA CLI application that supports the OpenConnect SSL VPN protocol.For more information, please visit https://github.com/tlslink/sslconUsage: sslcon [flags] sslcon [command]Available Commands: connect Connect to the VPN server disconnect Disconnect from the VPN server status Get VPN connection informationFlags: -h, --help help for sslconUse "sslcon [command] --help" for more information about a command.sudo ./vpnagent install# uninstallsudo ./vpnagent uninstallthe installed service on systemd linux
