relayctl — control the relay daemon

relayctl command [argument ...]

The relayctl program controls the relayd(8) daemon.

The following commands are available:

[name | id]
Disable a host. Treat it as though it were always down.
[name | id]
Enable the host. Start checking its health again.
filename
Reload the configuration from the specified file.
Disable verbose debug logging.
Enable verbose debug logging.
Continuously report any changes in the host checking engine and the pf(4) engine.
Schedule an immediate check of all hosts.
[name | id]
Disable a redirection. If it has pf(4) redirection rules installed, remove them. Mark the redirection's main table and – if applicable – disable the backup table as well.
[name | id]
Enable a redirection. Mark the redirection's main table and – if applicable – enable the backup table as well.
Reload the configuration file.
Show detailed status of hosts and tables. It will also print the last error for failed host checks; see the DIAGNOSTICS section below.
Show detailed status of redirections including the current and average access statistics. The statistics will be updated every minute. Redirections using the sticky-address option will count the number of sticky states, not the total number of redirected connections.
Show detailed status of relays including the current and average access statistics. The statistics will be updated every minute.
Show detailed status of routers including the configured network routes.
Dump the complete list of running relay sessions.
Display a list of all relays, redirections, routers, tables, and hosts.
[name | id]
Disable a table. Consider all hosts disabled. If it is a main table of a redirection which has a non-empty backup table, swap the contents of the pf(4) table with those of the backup table.
[name | id]
Enable a table. Start doing checks for all hosts that aren't individually disabled again.

/var/run/relayd.sock
UNIX-domain socket used for communication with relayd(8).

If a host is down and a previous check failed, relayctl will display the last error in the output of the show hosts command. This is especially useful for debugging server or configuration failures. The following errors will be reported:

No specific error was reported by the check engine.

All checks were aborted by an external event, like a configuration reload.

The check did not finish in the configured time of an interval. This can happen if there are too many hosts that have to be checked by relayd(8) and can be avoided by increasing the global interval option in relayd.conf(5).

 
 
The check failed because the remote host did not send a reply within the configured timeout.

 
 
 
 
The check failed because relayd(8) was not ready to send the request within the configured timeout.

 
 
 
 
 
An I/O error occurred. This indicates that relayd(8) was running low on resources, file descriptors, or was too busy to run the request. It can also indicate that a TLS or TCP protocol error occurred or that the connection was unexpectedly aborted.

 
The check failed because the protocol handshake did not succeed in opening a stateful connection with the remote host.

The external script executed by the check did not return a valid return code.

The payload data returned by the remote host did not match the expected pattern.

 
The remote host did not return a valid HTTP header or body.

The remote host did not return a matching HTTP error code. This may indicate a real server problem (a server error, the page was not found, permission was denied) or a configuration error. For example, it is a very common mistake that relayd(8) was configured to expect a HTTP 200 OK status but the host is returning a HTTP 302 Found redirection. See relayd.conf(5) for more information on validating the HTTP return code.

The remote host did not return the expected content and the computed digest was different to the configured value. See relayd.conf(5) for more information on validating the digest.

The relayctl program, formerly known as hoststatectl, first appeared in OpenBSD 4.1. It was renamed to relayctl in OpenBSD 4.3.
