SUDO_SENDLOG(8) System Manager's Manual SUDO_SENDLOG(8)
NAME
sudo_sendlog — send sudo I/O log to log server
SYNOPSIS
sudo_sendlog [-AnV] [-b ca_bundle] [-c cert_file] [-h host]
[-i iolog-id] [-k key_file] [-p port] [-r restart-point]
[-R reject-reason] [-s stop-point] [-t number] path
DESCRIPTION
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:
-A, --accept-only
Only send the accept event, not the I/O associated with the log.
This can be used to test the logging of accept events without
any associated I/O.
-b, --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.
-c, --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.
--help Display a short help message to the standard output and exit.
-h, --host
Connect to the specified host instead of localhost.
-i, --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.
-k, --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.
-n, --no-verify
If specified, the server's certificate will not be verified dur-
ing 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 se-
cured with TLS.
-p, --port
Use the specified network port when connecting to the log server
instead of the default, port 30344.
-r, --restart
Restart an interrupted connection to the log server. The speci-
fied 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.
-R, --reject
Send a reject event for the command using the specified
reject-reason, even though it was actually accepted locally.
This can be used to test the logging of reject events; no I/O
will be sent.
-s, --stop-after
Stop sending log records and close the connection when
stop-point is reached. This can be used for testing purposes to
send a partial I/O log to the server. Partial logs can be
restarted using the -r option. The stop-point is an elapsed
time specified in the form “seconds,nanoseconds”.
-t, --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.
-V, --version
Print the sudo_sendlog version and exit.
Debugging sendlog
sudo_sendlog supports a flexible debugging framework that is configured
via Debug lines in the sudo.conf(5) file.
