10.9.22 VPN-сервисы

Модуль (gnu services file-sharing) предоставляет следующие сервисы, помогающие с передачей файлов через одноранговые сети.

Bitmask

Scheme Variable: bitmask-service-type

A service type for the Bitmask VPN client. It makes the client available in the system and loads its polkit policy. Please note that the client expects an active polkit-agent, which is either run by your desktop-environment or should be run manually.

OpenVPN

It provides a client service for your machine to connect to a VPN, and a server service for your machine to host a VPN.

Scheme Procedure: openvpn-client-service [#:config (openvpn-client-configuration)]

Return a service that runs openvpn, a VPN daemon, as a client.

Scheme Procedure: openvpn-server-service [#:config (openvpn-server-configuration)]

Return a service that runs openvpn, a VPN daemon, as a server.

Both can be run simultaneously.

Available openvpn-client-configuration fields are:

openvpn-client-configuration parameter: package openvpn
