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 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 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 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 seconds.
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.
