SUDO_LOGSRVD.CONF(5) File Formats Manual SUDO_LOGSRVD.CONF(5)
NAME
sudo_logsrvd.conf — configuration for sudo_logsrvd
DESCRIPTION
The sudo_logsrvd.conf file is used to configure the sudo_logsrvd log
server. It uses an INI-style format made up of sections in square
brackets and “key = value” pairs specific to each section below the sec-
tion name. Depending on the key, values may be integers, booleans, or
strings. Section and key names are not case sensitive, but values are.
The pound sign (‘#’) is used to indicate a comment. Both the comment
character and any text after it, up to the end of the line, are ignored.
Lines beginning with a semi-colon (‘;’) are also ignored.
Long lines can be continued with a backslash (‘\’) as the last character
on the line. Leading white space is removed from the beginning of lines
even when the continuation character is used.
The “EXAMPLES” section contains a copy of the default sudo_logsrvd.conf
file.
The following configuration sections are recognized:
• server
• relay
• iolog
• eventlog
• syslog
• logfile
Each section is described in detail below.
server
The server section configures the address and port the server will lis-
ten on. The following keys are recognized:
listen_address = host[:port][(tls)]
The host name or IP address, optional port to listen on and an op-
tional Transport Layer Security (TLS) flag in parentheses.
The host may be a host name, an IPv4 address, an IPv6 address in
square brackets or the wild card entry ‘*’. A host setting of ‘*’
will cause sudo_logsrvd to listen on all configured network inter-
faces.
If the optional tls flag is present, sudo_logsrvd will secure the
connection with TLS version 1.2 or 1.3. Versions of TLS prior to
1.2 are not supported. See sudo_logsrvd(8) for details on gener-
ating TLS keys and certificates.
If a port is specified, it may either be a port number or a known
service name as defined by the system service name database. If
no port is specified, port 30343 will be used for plaintext con-
nections and port 30344 will be used for TLS connections.
The default value is:
listen_address = *:30343
listen_address = *:30344(tls)
which will listen on all configured network interfaces for both
plaintext and TLS connections. Multiple listen_address lines may
be specified to listen on more than one port or interface.
server_log = string
Where to log server warning and error messages. Supported values
are none, stderr, syslog, or a path name beginning with the ‘/’
character. A value of stderr is only effective when used in con-
junction with the -n option. The default value is syslog.
pid_file = path
The path to the file containing the process ID of the running
sudo_logsrvd. If set to an empty value, or if sudo_logsrvd is run
with the -n option, no pid_file will be created. If pid_file
refers to a symbolic link, it will be ignored. The default value
is /run/sudo/sudo_logsrvd.pid.
tcp_keepalive = boolean
If true, sudo_logsrvd will enable the TCP keepalive socket option
on the client connection. This enables the periodic transmission
of keepalive messages to the client. If the client does not re-
spond to a message in time, the connection will be closed. De-
faults to true.
timeout = number
The amount of time, in seconds, sudo_logsrvd will wait for the
client to respond. A value of 0 will disable the timeout. The
default value is 30.
tls_cacert = path
The path to a certificate authority bundle file, in PEM format, to
use instead of the system's default certificate authority database
when authenticating clients. The default is to use
/etc/ssl/sudo/cacert.pem if it exists, otherwise the system's de-
fault certificate authority database is used.
tls_cert = path
The path to the server's certificate file, in PEM format. The de-
fault value is /etc/ssl/sudo/certs/logsrvd_cert.pem.
tls_checkpeer = bool
If true, client certificates will be validated by sudo_logsrvd;
clients without a valid certificate will be unable to connect. If
false, no validation of client certificates will be performed. It
true and client certificates are created using a private certifi-
cate authority, the tls_cacert setting must be set to a CA bundle
that contains the CA certificate used to generate the client cer-
tificate. The default value is false.
tls_ciphers_v12 = string
A list of ciphers to use for connections secured by TLS version
1.2 only, separated by a colon ‘:’. See the “CIPHER LIST FORMAT”
section in openssl-ciphers(1) for full details. The default value
is “HIGH:!aNULL” which consists of encryption cipher suites with
key lengths larger than 128 bits, and some cipher suites with
128-bit keys. Cipher suites that offer no authentication are ex-
cluded.
tls_ciphers_v13 = string
A list of ciphers to use for connections secured by TLS version
1.3 only, separated by a colon ‘:’. Supported cipher suites de-
pend on the version of OpenSSL used, but should include the fol-
lowing:
TLS_AES_128_GCM_SHA256
TLS_AES_256_GCM_SHA384
TLS_CHACHA20_POLY1305_SHA256
TLS_AES_128_CCM_SHA256
TLS_AES_128_CCM_8_SHA256
The default cipher suite is “TLS_AES_256_GCM_SHA384”.
tls_dhparams = path
The path to a file containing custom Diffie-Hellman parameters in
PEM format. This file can be created with the following command:
openssl dhparam -out /etc/sudo_logsrvd_dhparams.pem 2048
By default, sudo_logsrvd will use the OpenSSL defaults for Diffie-
Hellman key generation.
tls_key = path
The path to the server's private key file, in PEM format. The de-
fault value is /etc/ssl/sudo/private/logsrvd_key.pem.
tls_verify = bool
If true, sudo_logsrvd will validate its own certificate at startup
time or when the configuration is changed. If false, no verifica-
tion is performed of the server certificate. When using self-
signed certificates without a certificate authority, this setting
should be set to false. The default value is true.
relay
The relay section configures the optional logsrv relay host and port the
server will connect to. The TLS configuration keys are optional, by de-
fault the corresponding keys in the “server” section will be used. They
are only present in this section to make it possible for the relay con-
nection to use a different set of TLS parameters from the client-facing
server. The following keys are recognized:
connect_timeout = number
The amount of time, in seconds, sudo_logsrvd will wait for the
connection to a relay_host (see below) to complete. Once the con-
nection is complete, the timeout setting controls the amount of
time sudo_logsrvd will wait for the relay to respond. A value of
0 will disable the timeout. The default value is 30.
relay_dir = path
The directory in which log messages are temporarily stored before
they are sent to the relay host. Messages are stored in the wire
format specified by sudo_logsrv.proto(5) The default value is
/var/log/sudo_logsrvd.
relay_host = host[:port][(tls)]
The relay host name or IP address, optional port to connect to and
an optional Transport Layer Security (TLS) flag in parentheses.
The syntax is identical to listen_address in the “server” section
with one exception: the wild card ‘*’ syntax is not supported.
When this setting is enabled, messages from the client will be
forwarded to one of the specified relay hosts instead of being
stored locally. The host could be running an instance of
sudo_logsrvd or another server that supports the
sudo_logsrv.proto(5) protocol.
If multiple relay_host lines are specified, the first available
relay host will be used.
retry_interval = number
The number of seconds to wait after a connection error before mak-
ing a new attempt to forward a message to a relay host. The de-
fault value is 30.
store_first = boolean
If true, sudo_logsrvd will store logs locally before relaying
them. Once the log is complete, a connection to the relay host is
opened and the log is relayed. If the network connection is in-
terrupted before the log can be fully transferred, it will be re-
transmitted later. The default is to relay logs in real-time.
tcp_keepalive = boolean
If true, sudo_logsrvd will enable the TCP keepalive socket option
on the relay connection. This enables the periodic transmission
of keepalive messages to the relay server. If the relay does not
respond to a message in time, the connection will be closed.
timeout = number
The amount of time, in seconds, sudo_logsrvd will wait for the re-
lay server to respond after a connection has succeeded. A value
of 0 will disable the timeout. The default value is 30.
tls_cacert = path
The path to a certificate authority bundle file, in PEM format, to
use instead of the system's default certificate authority database
when authenticating clients. The default is to use the value
specified in the “server” section, or the system's default cer-
tificate authority database if no value is set.
tls_cert = path
The path to the server's certificate file, in PEM format. The de-
fault is to use the value specified in the “server” section.
tls_checkpeer = bool
If true, the relay host's certificate will be validated by
sudo_logsrvd; connections to a relay without a valid certificate
will fail. If false, no validation of relay certificates will be
performed. It true and relay certificates are created using a
private certificate authority, the tls_cacert setting must be set
to a CA bundle that contains the CA certificate used to generate
the relay certificate. The default is to use the value specified
in the “server” section.
tls_ciphers_v12 = string
A list of ciphers to use for connections secured by TLS version
1.2 only, separated by a colon ‘:’. See the “CIPHER LIST FORMAT”
section in openssl-ciphers(1) for full details. The default is to
use the value specified in the “server” section.
tls_ciphers_v13 = string
A list of ciphers to use for connections secured by TLS version
1.3 only, separated by a colon ‘:’. Supported cipher suites de-
pend on the version of OpenSSL used, see the “server” section for
more information. The default is to use the value specified in
the “server” section.
tls_dhparams = path
The path to a file containing custom Diffie-Hellman parameters in
PEM format. The default is to use the value specified in the
“server” section.
tls_key = path
The path to the server's private key file, in PEM format. The de-
fault is to use the value specified in the “server” section.
tls_verify = bool
If true, the server's certificate used for relaying will be veri-
fied at startup. If false, no verification is performed of the
server certificate. When using self-signed certificates without a
certificate authority, this setting should be set to false. The
default is to use the value specified in the “server” section.
iolog
The iolog section configures I/O log parameters. These settings are
identical to the I/O configuration in sudoers(5). The following keys
are recognized:
iolog_compress = boolean
If set, I/O logs will be compressed using zlib. Enabling compres-
sion can make it harder to view the logs in real-time as the pro-
gram is executing due to buffering. The default value is false.
iolog_dir = path
The top-level directory to use when constructing the path name for
the I/O log directory. The session sequence number, if any, is
stored in the directory. The default value is /var/log/sudo-io.
The following percent (‘%’) escape sequences are supported:
%{seq}
expanded to a monotonically increasing base-36 sequence num-
ber, such as 0100A5, where every two digits are used to form
a new directory, e.g., 01/00/A5
%{user}
expanded to the invoking user's login name
%{group}
expanded to the name of the invoking user's real group-ID
%{runas_user}
expanded to the login name of the user the command will be
run as (e.g., root)
%{runas_group}
expanded to the group name of the user the command will be
run as (e.g., wheel)
%{hostname}
expanded to the local host name without the domain name
%{command}
expanded to the base name of the command being run
In addition, any escape sequences supported by the system's
strftime(3) function will be expanded.
To include a literal ‘%’ character, the string ‘%%’ should be
used.
iolog_file = path
The path name, relative to iolog_dir, in which to store I/O logs.
It is possible for iolog_file to contain directory components.
The default value is “%{seq}”.
See the iolog_dir setting above for a list of supported percent
(‘%’) escape sequences.
In addition to the escape sequences, path names that end in six or
more Xs will have the Xs replaced with a unique combination of
digits and letters, similar to the mktemp(3) function.
If the path created by concatenating iolog_dir and iolog_file al-
ready exists, the existing I/O log file will be truncated and
overwritten unless iolog_file ends in six or more Xs.
iolog_flush = boolean
If set, I/O log data is flushed to disk after each write instead
of buffering it. This makes it possible to view the logs in real-
time as the program is executing but may significantly reduce the
effectiveness of I/O log compression. I/O logs are always flushed
before sending a commit point to the client regardless of this
setting. The default value is true.
iolog_group = name
The group name to look up when setting the group-ID on new I/O log
files and directories. If iolog_group is not set, the primary
group-ID of the user specified by iolog_user is used. If neither
iolog_group nor iolog_user are set, I/O log files and directories
are created with group-ID 0.
iolog_mode = mode
The file mode to use when creating I/O log files. Mode bits for
read and write permissions for owner, group, or other are honored,
everything else is ignored. The file permissions will always in-
clude the owner read and write bits, even if they are not present
in the specified mode. When creating I/O log directories, search
(execute) bits are added to match the read and write bits speci-
fied by iolog_mode. The default value is 0600.
iolog_user = name
The user name to look up when setting the owner of new I/O log
files and directories. If iolog_group is set, it will be used in-
stead of the user's primary group-ID. By default, I/O log files
and directories are created with user and group-ID 0.
log_passwords = bool
Most programs that require a user's password will disable echo be-
fore reading the password to avoid displaying the plaintext pass-
word on the screen. However, if terminal input is being logged,
the password will still be present in the I/O log. If
log_passwords is set to false, sudo_logsrvd will attempt to pre-
vent passwords from being logged. It does this by using the regu-
lar expressions in passprompt_regex to match a password prompt in
the terminal output buffer. When a match is found, input charac-
ters in the I/O log will be replaced with ‘*’ until either a line
feed or carriage return is found in the terminal input or a new
terminal output buffer is received. If, however, a program dis-
plays characters as the user types them (such as sudo when the
pwfeedback option is set), only the first character of the pass-
word will be replaced in the I/O log. The default value is true.
maxseq = number
The maximum sequence number that will be substituted for the
“%{seq}” escape in the I/O log file (see the iolog_dir description
above for more information). While the value substituted for
“%{seq}” is in base 36, maxseq itself should be expressed in deci-
mal. Values larger than 2176782336 (which corresponds to the base
36 sequence number “ZZZZZZ”) will be silently truncated to
2176782336. The default value is 2176782336.
passprompt_regex = string
One or more POSIX extended regular expressions used to match pass-
word prompts in the terminal output when log_passwords is dis-
abled. As an extension, if the regular expression begins with
“(?i)”, it will be matched in a case-insensitive manner. Multiple
passprompt_regex settings may be specified. Each regular expres-
sion is limited to 1024 characters. The default value is
“[Pp]assword[: ]*”.
eventlog
The eventlog section configures how (and if) security policy events are
logged.
log_type = string
Where to log accept, reject, and alert events reported by the pol-
icy. Supported values are syslog, logfile, and none. The default
value is syslog.
log_exit = boolean
If true, sudo_logsrvd will log an event when a command exits or is
terminated by a signal. Defaults to false.
log_format = string
The event log format. Supported log formats are:
json Currently, this is an alias for json_pretty. In a future
version of sudo_logsrvd, json will be equivalent to
json_compact. JSON log entries contain the full contents of
the accept, reject, exit and alert messages.
json_compact
Log events in “compact” (minified) JSON format. Each event
is written as a separate JSON object on single line without
extraneous white space. Due to limitations of the protocol,
JSON events sent via syslog may be truncated.
json_pretty
Log events in “pretty” JSON format. When logging to a file,
the entire file is treated as a single JSON object consist-
ing of multiple events, each event spanning multiple lines.
When logging via syslog, there is no difference between the
json_pretty and json_compact formats.
sudo Log events in traditional sudo-style log format. See the
EVENT LOGGING section in sudoers(5) for details.
The default value is sudo.
syslog
The syslog section configures how events are logged via syslog(3).
facility = string
Syslog facility if syslog is being used for logging. Defaults to
authpriv.
The following syslog facilities are supported: authpriv (if your
OS supports it), auth, daemon, user, local0, local1, local2,
local3, local4, local5, local6, and local7.
accept_priority = string
Syslog priority to use when the user is allowed to run a command
and authentication is successful. Defaults to notice.
The following syslog priorities are supported: alert, crit, debug,
emerg, err, info, notice, warning, and none. Setting it to a
value of none will disable logging of successful commands.
reject_priority = string
Syslog priority to use when the user is not allowed to run a com-
mand or when authentication is unsuccessful. Defaults to alert.
See accept_priority for the list of supported syslog priorities.
alert_priority = string
Syslog priority to use for event log alert messages received from
the client. Defaults to alert.
See accept_priority for the list of supported syslog priorities.
maxlen = number
On many systems, syslog(3) has a relatively small log buffer.
IETF RFC 5424 states that syslog servers must support messages of
at least 480 bytes and should support messages up to 2048 bytes.
By default, sudo_logsrvd creates log messages up to 960 bytes
which corresponds to the historic BSD syslog implementation which
used a 1024 byte buffer to store the message, date, hostname, and
program name.
To prevent syslog messages from being truncated, sudo_logsrvd will
split up sudo-style log messages that are larger than maxlen
bytes. When a message is split, additional parts will include the
string “(command continued)” after the user name and before the
continued command line arguments. JSON-format log entries are
never split and are not affected by maxlen.
server_facility = string
Syslog facility if syslog is being used for server warning mes-
sages. See above for a list of supported facilities. Defaults to
daemon
logfile
The logfile section consists of settings related to logging to a plain
file (not syslog).
path = string
The path to the file-based event log. This path must be fully-
qualified and start with a ‘/’ character. The default value is
/var/log/sudo.log.
time_format = string
The string used when formatting the date and time for file-based
event logs. Formatting is performed via the system's strftime(3)
function so any escape sequences supported by that function will
be expanded. The default value is “%h %e %T” which produces dates
like “Oct 3 07:15:24” in the ‘C’ locale.

# of at least 480 bytes and should support messages up to 2048 bytes.
# Messages larger than this value will be split into multiple messages.
#maxlen = 960
# The syslog facility to use for event log messages.
# The following syslog facilities are supported: authpriv (if your OS
# supports it), auth, daemon, user, local0, local1, local2, local3,
# local4, local5, local6, and local7.
#facility = authpriv
# Syslog priority to use for event log accept messages, when the command
# is allowed by the security policy. The following syslog priorities are
# supported: alert, crit, debug, emerg, err, info, notice, warning, none.
#accept_priority = notice
# Syslog priority to use for event log reject messages, when the command
# is not allowed by the security policy.
#reject_priority = alert
# Syslog priority to use for event log alert messages reported by the
# client.
#alert_priority = alert
# The syslog facility to use for server warning messages.
# Defaults to daemon.
#server_facility = daemon
[logfile]
# The path to the file-based event log.
# This path must be fully-qualified and start with a '/' character.
#path = /var/log/sudo.log
# The format string used when formatting the date and time for
# file-based event logs. Formatting is performed via strftime(3) so
# any format string supported by that function is allowed.
#time_format = %h %e %T
