sudo_sendlogsend sudo I/O log to log server

sudo_sendlog [-nV] [-b ca_bundle] [-c cert_file] [-h host] [-i iolog-id] [-k key_file] [-p port] [-r restart-point] [-t number] path

sudo_sendlog can be used to send the existing sudoers I/O log path to a remote log server such as sudo_logsrvd(8) for central storage.

The options are as follows:

, --ca-bundle
The path to a certificate authority bundle file, in PEM format, to use instead of the system's default certificate authority database when authenticating the log server. The default is to use the system's default certificate authority database.
, --cert
The path to the client's certificate file in PEM format. This setting is required when the connection to the remote log server is secured with TLS.
Display a short help message to the standard output and exit.
, --host
Connect to the specified host instead of localhost.
, --iolog-id
Use the specified iolog-id when restarting a log transfer. The iolog-id is reported by the server when it creates the remote I/O log. This option may only be used in conjunction with the -r option.
, --key
The path to the client's private key file in PEM format. This setting is required when the connection to the remote log server is secured with TLS.
, --no-verify
If specified, the server's certificate will not be verified during the TLS handshake. By default, sudo_sendlog verifies that the server's certificate is valid and that it contains either the server's host name or its IP address. This setting is only supported when the connection to the remote log server is secured with TLS.
, --port
Use the specified network port when connecting to the log server instead of the default, port 30344.
, --restart
Restart an interrupted connection to the log server. The specified restart-point is used to tell the server the point in time at which to continue the log. The restart-point is specified in the form “seconds,nanoseconds” and is usually the last commit point received from the server. The -i option must also be specified when restarting a transfer.
, --test
Open number simultaneous connections to the log server and send the specified I/O log file on each one. This option is useful for performance testing.
, --version
Print the sudo_sendlog version and exit.

sudo_sendlog supports a flexible debugging framework that is configured via Debug lines in the sudo.conf(5) file.
