rtrdRPKI-to-Router (RTR) daemon

rtrd [-fvV] [-b bind_address] [-m max_version] [-p port] [-s socket]

The rtrd daemon is an RPKI-to-Router (RTR) cache server. The rtrd program supports RTR protocol versions 0, 1, and 2.

The options are as follows:

bind_address
Use bind_address as the listener address for connections from clients. The default bind_address is ‘0.0.0.0’.
Remain in foreground.
max_version
Use max_version as the maximum supported version in protocol version negotiation. The default protocol is version 2.
port
Listen on port for client connections. The default port is 323.
socket
Use socket instead of the default /var/run/rtrd.sock for communication with rtrctl(8).
Increase verbosity.
Display version and exit.

/var/run/rtrd.sock
Unix-domain socket used for communication with rtrctl(8).

The rtrd utility exits 0 on success, and >0 if an error occurs.
