SUDO_LOGSRVD.CONF(5) File Formats Manual SUDO_LOGSRVD.CONF(5)
sudo_logsrvd.conf — configuration for sudo_logsrvd
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 section 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 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 listen on. The following keys are recognized:
listen_address = host[:port][(tls)]
The host name or IP address, optional port to listen on and
an optional 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 interfaces.
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 generating 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 connections 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 conjunction 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 respond to a message in time, the
connection will be closed. Defaults 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 default certificate authority
database is used.
tls_cert = path
The path to the server's certificate file, in PEM format.
The default 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 certificate
authority, the tls_cacert setting must be set to a CA
bundle that contains the CA certificate used to generate
the client certificate. 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 excluded.
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 depend on the version of OpenSSL used, but
should include the following:
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 default 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 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 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 default the corresponding keys in the “server”
section will be used. They are only present in this section to
make it possible for the relay connection 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 connection 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 making a new attempt to forward a message to a relay
host. The default 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 interrupted before the log can be
fully transferred, it will be retransmitted 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 relay 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 certificate authority
database if no value is set.
tls_cert = path
The path to the server's certificate file, in PEM format.
The default 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 depend 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 default is to use the value specified in the “server”
section.
tls_verify = bool
If true, the server's certificate used for relaying will be
verified 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
compression can make it harder to view the logs in real-
time as the program 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 number, 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 already 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 include 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 specified 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 instead 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 before reading the password to avoid displaying the
plaintext password 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 prevent passwords from being
logged. It does this by using the regular expressions in
passprompt_regex to match a password prompt in the terminal
output buffer. When a match is found, input characters 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 displays characters as the user types them (such as
sudo when the pwfeedback option is set), only the first
character of the password 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 decimal. 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 password prompts in the terminal output when
log_passwords is disabled. 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 expression 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 policy. 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 “sudo” for
traditional sudo-style logs and “json” for JSON-format
logs. The JSON log entries contain the full contents of
the accept, reject, exit and alert messages. 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 command 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
messages. 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.
