Description:

OpenConnect server (ocserv) is an SSL VPN server. Its purpose is to be
a secure, small, fast and configurable VPN server. It implements the
OpenConnect SSL VPN protocol, and has also (currently experimental)
compatibility with clients using the AnyConnect SSL VPN protocol. The
OpenConnect VPN protocol uses the standard IETF security protocols
such as TLS 1.2, and Datagram TLS to provide the secure VPN service.
The server is implemented primarily for the GNU/Linux platform but its
code is designed to be portable to other UNIX variants as well.
