ql2tpd - Man Page

ql2tpd [ arguments ]

ql2tpd is a daemon for creating static L2TPv3 (RFC 3931) tunnels and sessions.

Static (or quiescent) tunnels and sessions implement only the data plane transport: the L2TP control protocol is not used. This can be useful for setting up static L2TPv3 links where host configuration is known in advance.

When configured to bring up static tunnel and session instances, ql2tpd represents a more convenient way to bring up static sessions than ip l2tp commands.

Additionally, ql2tpd supports the use of a periodic keep-alive packet for tunnels it is managing (controlled by the configuration file hello_timeout parameter).

This allows for the detection of tunnel failure, which will then tear down the sessions running in that tunnel. This mode of operation must only be enabled if the peer is also running ql2tpd.

ql2tpd requires root permissions to run, and is driven by a configuration file which details the tunnel and session instances to create.

For further details of the configuration format, please refer to ql2tpd.toml(5).
