1 Introduction

This document describes the system parameters of the X-Road components – of the security server, the central server and the configuration proxy. Additionally, changing the default values of the system parameters are explained. Please note the term 'vanilla' in the documentation. In X-Road context vanilla means the X-Road without any of the country specific customizations, settings etc. The vanilla version of X-Road security server is installed with xroad-securityserver package. The country specific versions are installed with xroad-securityserver-XX where XX is the country code f.ex. FI or EE.

2 Changing the System Parameter Values

The system parameters specify various characteristics of the system, such as port numbers, timeouts and paths to files on disk. The system parameters of the X-Road components are mainly stored in configuration files. Additionally, X-Road central server stores some system parameters in the database.

Changing the values of the system parameters is strongly discouraged, since it may cause unexpected system behaviour.

2.1 Changing the System Parameter Values in Configuration Files

The configuration files are INI files [INI], where each section contains parameters for a particular server component.

In order to override the default values of system parameters, create or edit the file

/etc/xroad/conf.d/local.ini

Each system parameter affects a specific server component. To change the value of a system parameter, a section for the affected component must be created in the INI file. The name-value pairs of the system parameters for that component are written under the section, one pair per line.

The following format is used for the sections:

[ServerComponent]
SystemParameterName1=Value1
SystemParameterName2=Value2

For example, to configure the parameter client-http-port for the proxy component, the following lines must be added to the configuration file:

[proxy]
client-http-port=1234

Multiple parameters can be configured under the same section:

[proxy]
client-http-port=1234
server-listen-port=20000

NB! Changing the parameter values in the configuration files requires restarting of the server.

WARNING! The value of the parameter is not validated, thus care must be taken when changing the value. For example, setting the port number to a non-numeric value in the configuration will cause the system to crash.

2.2 Changing the System Parameter Values in the Central Server Database

The central server database can be accessed with the psql utility using the following command (password is defined in /etc/xroad/db.properties):

psql -U centerui -h localhost centerui_production

The default value of a system parameter can be overridden by adding the parameter name and value to the system_parameters table:

INSERT INTO system_parameters (key, value, created_at, updated_at) VALUES ('parameter_name', 'parameter_value', (now() at time zone 'utc'), (now() at time zone 'utc'));

To edit the value of a system parameter already inserted into the system_parameters table:

UPDATE system_parameters SET value = '*parameter_value*', updated_at = (now() at time zone 'utc') WHERE key = 'parameter_name';

To restore the default value of a system parameter, delete the parameter from the system_parameters table:

DELETE FROM system_parameters WHERE key = 'parameter_name';

NB! Modifying or deleting system parameters other than the ones listed in section System Parameters in the Database will cause the system to crash.

2.3 Changing the Global Configuration Generation Interval in the Central Server

In order to override the default value of the global configuration generation interval, edit the cron expression [CRON] in the file

/etc/cron.d/xroad-center

The default contents of the file are the following:

#!/bin/sh
* * * * * xroad curl http://127.0.0.1:8084/managementservice/gen_conf 2>&1 > /dev/null;

NB! Global configuration generation interval must be modified with extreme care. Misuse of the global configuration generation interval may hinder the operation of the whole X-Road instance.

The configuration generation interval must be shorter than the value of global configuration expiration interval (confExpireIntervalSeconds, see section 4.2 ), or else the configuration downloaded by the configuration clients (security servers or configuration proxies) will always expire before valid configuration becomes available. It is highly recommended that the global configuration generation interval is multiple times smaller than the global configuration expiration interval.

3 Security Server System Parameters

This chapter describes the system parameters used by the components of the X-Road security server. For instructions on how to change the parameter values, see section Changing the System Parameter Values in Configuration Files.

3.1 Common parameters : [common]

Parameter	Default value	Description

client-https-port	443 8443 (RHEL)			TCP port on which the service client's security server listens for HTTPS requests from client applications.
client-timeout	30000			Defines the time period (in milliseconds), for which the service client's security server tries to connect to the service provider's security server. When the timeout is reached, the service client's security server informs the service client's information system that a service timeout has occurred.
configuration-anchor-file	/etc/xroad/configuration-anchor.xml			Absolute file name of the configuration anchor that is used to download global configuration.
connector-host	0.0.0.0		127.0.0.1	IP address on which the service client's security server listens for connections from client applications. The value 0.0.0.0 allows listening on all IPv4 interfaces. The value 127.0.0.1 allows listening on localhost only.

ocsp-responder-listen-address	0.0.0.0			IP address on which the service provider's security server listens for requests for OCSP responses from the service client's security server. The service client's security server downloads OCSP responses from the service provider's security server while establishing a secure connection between the security servers. The value 0.0.0.0 allows listening on all IPv4 interfaces. Must match the value of proxy.server-listen-address.
ocsp-responder-port	5577			TCP port on which the service provider's security server listens for requests for OCSP responses from the service client's security server. The service client's security server downloads OCSP responses from the service provider's security server while establishing a secure connection between the security servers.
ocsp-responder-client-connect-timeout	20000			Connect timeout (in milliseconds) of the OCSP responder client. The service client's security server downloads OCSP responses from the service provider's security server while establishing a secure connection between the security servers.
ocsp-responder-client-read-timeout	30000			Read timeout (in milliseconds) of the OCSP responder client. The service client's security server downloads OCSP responses from the service provider's security server while establishing a secure connection between the security servers.
server-listen-address	0.0.0.0			IP address on which the service provider's security server listens for connections from the service client's security servers. The value 0.0.0.0 allows listening on all IPv4 interfaces.
server-listen-port	5500			TCP port on which the service provider's security server listens for connections from the service client's security server.
server-port	5500			Destination TCP port for outgoing queries in the service client's security server.
jetty-clientproxy-configuration-file	/etc/xroad/jetty/clientproxy.xml			Absolute filename of the Jetty configuration file for the service client's security server. For more information about configuring Jetty server, see https://www.eclipse.org/jetty/documentation/jetty-9/index.html.
jetty-serverproxy-configuration-file	/etc/xroad/jetty/serverproxy.xml			Absolute filename of the Jetty configuration file for the service provider's security server. For more information about configuring Jetty server, see https://www.eclipse.org/jetty/documentation/jetty-9/index.html.
jetty-ocsp-responder-configuration-file	/etc/xroad/jetty/ocsp-responder.xml			Absolute filename of the Jetty configuration file for the OCSP responder of the service provider's security server. For more information about configuring Jetty server, see https://www.eclipse.org/jetty/documentation/jetty-9/index.html.
ssl-enabled	true			If true, TLS is used for connections between the service client's and service provider's security servers.
client-tls-ciphers	See 1			TLS ciphers (comma-separated list) enabled on the client-side interfaces (for both incoming and outgoing requests). (since version 6.7)
xroad-tls-ciphers	See 2			TLS ciphers (comma-separated list in preferred order) accepted on requests between security servers, and between operational monitoring daemon and client. (since version 6.20)
client-tls-protocols	TLSv1.2			TLS protocols (comma-separated list) enabled on the client-side interfaces (for both incoming and outgoing requests). For backward compatibility TLSv1.1 is still supported on the client-side interfaces for outgoing requests (since version 6.7)
server-connector-initial-idle-time	30000			The initial idle time (in milliseconds) that unauthenticated connections are allowed to be idle before the provider security server starts closing them. Value of 0 means that an infinite idle time is allowed.
server-connector-max-idle-time	0	120000		The maximum time (in milliseconds) that connections from a service consuming security server to a service providing security server are allowed to be idle before the provider security server starts closing them. Value of 0 means that an infinite idle time is allowed. A non-zero value should allow some time for a pooled connection to be idle, if pooled connections are to be supported.
server-connector-so-linger	-1			The SO_LINGER time (in seconds) at the service providing security server end for connections between security servers. A value larger than 0 means that upon closing a connection, the system will allow SO_LINGER seconds for the transmission and acknowledgement of all data written to the peer, at which point the socket is closed gracefully. Upon reaching the linger timeout, the socket is closed forcefully, with a TCP RST. Enabling the option with a timeout of zero does a forceful close immediately. Value of -1 disables the forceful close.
server-support-clients-pooled-connections	false	true		Whether this service providing security server supports pooled connections from the service consumer side. If set to false, connections are to be closed immediately after each message. This may be a wanted approached for security servers behind load balancers.
client-connector-initial-idle-time	30000			The initial idle time (in milliseconds) that client connections are allowed to be idle before the security server starts closing them. Value of 0 means that an infinite idle time is allowed.
client-connector-max-idle-time	0			The maximum time (in milliseconds) that connections from a service consumer to the service consumer's security server are allowed to be idle before the security server starts closing them. Value of 0 means that an infinite idle time is allowed.
client-connector-so-linger	-1			The SO_LINGER time (in seconds) at the service consuming security server end for connections between a consumer and a security server. A value larger than 0 means that upon closing a connection, the system will allow SO_LINGER seconds for the transmission and acknowledgement of all data written to the peer, at which point the socket is closed gracefully. Upon reaching the linger timeout, the socket is closed forcefully, with a TCP RST. Enabling the option with a timeout of zero does a forceful close immediately. Value of -1 disables the forceful close.
client-httpclient-timeout	0			The maximum time (SO_TIMEOUT, in milliseconds) that connections from a service consuming security server to a service providing security server are allowed to wait for a response before the consumer end httpclient gives up. Value of 0 means that an infinite wait time is allowed. This does not affect idle connections.
client-httpclient-so-linger	-1			The SO_LINGER time (in seconds) at the service consuming security server end for connections between security servers. A value larger than 0 means that upon closing a connection, the system will allow SO_LINGER seconds for the transmission and acknowledgement of all data written to the peer, at which point the socket is closed gracefully. Upon reaching the linger timeout, the socket is closed forcefully, with a TCP RST. Enabling the option with a timeout of zero does a forceful close immediately. Value of -1 disables the forceful close.
client-use-idle-connection-monitor	true			Should the idle connection monitor be used to clean up idle and expired connections from the connection pool.
client-idle-connection-monitor-interval	30000			How often (in milliseconds) should the connection monitor go through the pooled connections to see if it can clean up any idle or expired connections. This option requires the connection monitor to be enabled to have any effect.
client-idle-connection-monitor-timeout	60000			The minimum time (in milliseconds) that a pooled connection must be unused (idle) before it can be removed from the pool. Note that removal from the pool also depends on how often the connection monitor runs. This option requires the connection monitor to be enabled to have any effect.
pool-total-max-connections	10000			The total maximum number of connections that are allowed in the pool.
pool-total-default-max-connections-per-route	2500			The default route specific connection maximum that is set unless a route specific connection limit is set. Due to the current implementation, this is actually the total maximum limit of connections, indepedent of what the above setting is.
pool-validate-connections-after-inactivity-of-millis	2000			When reusing a pooled connection to a service providing security server, check that the connection (the socket) is not half-closed if it has been idle for at least this many milliseconds. This method cannot detect half-open connections. Value of -1 disables the check.
pool-enable-connection-reuse	false	true		Allow pooled connections between security servers to be used more than once on the client side. The service provider end of the connections has to have the setting server-support-clients-pooled-connections=true for the pooling to work between a provider and consumer security servers.
client-use-fastest-connecting-ssl-socket-autoclose	true			On TLS connections between security servers, should the underlying TCP-layer connection (socket) be closed on the service consumer end when the TLS layer connection is terminated.
client-fastest-connecting-ssl-uri-cache-period	3600			When a service consumer's security server finds the fastest responding service providing security server, how long the result should be kept in the TLS session cache? 0 to disable.
health-check-port	0 (disabled)			The TCP port where the health check service listens to requests. Setting the port to 0 disables the health check service completely.
health-check-interface	0.0.0.0			The network interface where the health check service listens to requests. Default is all available interfaces.
actorsystem-port	5567			The (localhost) port where the proxy actorsystem binds to. Used for communicating with xroad-signer and xroad-monitor.
server-conf-cache-period	60			Number of seconds to keep selected serverconf configuration items in memory
server-conf-client-cache-size	100			Maximum number of local clients to keep cached
server-conf-service-cache-size	1000			Maximum number of services to keep cached
server-conf-acl-cache-size	100000			Maximum number of access rights to keep cached in memory.
enforce-client-is-cert-validity-period-check	false			Whether to reject a request when client information system certificate is expired or not yet valid.
backup-encryption-enabled	false			Whether to encrypt security server backup files using server's OpenPGP key.
backup-encryption-keyids				Comma-separated list of additional recipient OpenPGP key identifiers.

Note about database-properties file: Management REST API module uses the same database-properties file, but limits the configuration parameters usage:

• hibernate.dialect cannot be changed, it is fixed to a custom PostgreSQL dialect.

• out of hibernate.connection.* parameters, only url, username and password can be configured.

This in practice limits configurability to different kinds of PostgreSQL database configurations, and it is not possible to use for example MySQL as a data store for REST API module.

3.3 Proxy User Interface parameters: [proxy-ui]

Proxy-ui has been removed in version 6.24 and it's parameters are not used anymore.

proxy-ui-api parameters replace the old [proxy-ui] parameters.

3.4 Signer parameters: [signer]

Parameter	Default value	FI-package value	EE-package value	Description
ocsp-cache-path	/var/cache/xroad			Absolute path to the directory where the cached OCSP responses are stored.
enforce-token-pin-policy	false	true	true	Controls enforcing the token pin policy. When set to true, software token pin is required to be at least 10 ASCII characters from at least tree character classes (lowercase letters, uppercase letters, digits, special characters). (since version 6.7.7)
client-timeout	60000			Signing timeout in milliseconds.
device-configuration-file	/etc/xroad/signer/devices.ini			Absolute filename of the configuration file of the signature creation devices.

3.5 Anti-DOS parameters: [anti-dos]

Parameter	Default value	Description
enabled	true	Flag for enabling or disabling the AntiDOS system.

3.7 Message log add-on parameters: [message-log]

Parameter	Default value	FI-package value	EE-package value	Description
message-body-logging	true	false		Whether message body should be logged or not. If true, the messages are logged in their original form. If false, the message body is cleared of its contents (SOAP body will have an empty child element inside it; REST message body, service path and query parameters will be omitted). In addition, the SOAP header and REST HTTP headers will only have specific set of elements logged, see Note on logged X-Road message headers . As a side effect, details such as formatting and namespace labels of the xml message can be changed and new elements may be introduced for default values in SOAP header. Removal of message body is usually done for confidentiality reasons (body contains data that we do not want to have in the logs). Note that changing the message this way prevents verifying its signature with the asicverifier tool.
soap-body-logging	true	false		(deprecated, see message-body-logging)
enabled-body-logging-local-producer-subsystems				Subsystem-specific overrides for message body logging when message-body-logging = false. This parameter defines logging for local producer subsystems, that is, our subsystems that produce some service which external clients use. Comma-separated list of client identifiers for which message body logging is enabled. For example FI/ORG/1710128-9/SUBSYSTEM_A1, FI/ORG/1710128-9/SUBSYSTEM_A2 where - FI = x-road instance - ORG = member class - 1710128-9 = member code - SUBSYSTEM_A1 = subsystem code This parameter can only be used on subsystem-level, it is not possible to configure message body logging per member. If a subsystem has forward slashes “/” in for example subsystem code, those subsystems can’t be configured with this parameter.
enabled-body-logging-remote-producer-subsystems				Subsystem-specific overrides for remote producer subsystems, that is, remote subsystems that produce services which we use. Parameter is used when message-body-logging = false.
disabled-body-logging-local-producer-subsystems				Same as enabled-body-logging-local-producer-subsystems, but this parameter is used when message-body-logging = true.
disabled-body-logging-remote-producer-subsystems				Same as enabled-body-logging-remote-producer-subsystems, but this parameter is used when message-body-logging = true.
acceptable-timestamp-failure-period	14400	18000		Defines the time period (in seconds) for how long is time-stamping allowed to fail (for whatever reasons) before the message log stops accepting any more messages (and consequently the security server stops accepting requests). Set to 0 to disable this check. The value of this parameter should not be lower than the value of the central server system parameter timeStampingIntervalSeconds.
archive-interval	0 0 0/6 1/1 * ? *			CRON expression [CRON] defining the interval of archiving the time-stamped messages.
archive-max-filesize	33554432			Maximum size for archived files in bytes. Reaching the maximum value triggers file rotation.

clean-interval	0 0 0/12 1/1 * ? *			CRON expression [CRON] for deleting any time-stamped and archived records that are older than message-log.keep-records-for from the database.
hash-algo-id	SHA-512			The algorithm identifier used for hashing in the message log. Possible values are - SHA-224, - SHA-256, - SHA-384, - SHA-512.
keep-records-for	30			Number of days to keep time-stamped and archived records in the database of the security server. If a time-stamped and archived message record is older than this value, the record is deleted from the database.
timestamp-immediately	false			If true, the time-stamp is created synchronously for each request message. This is a security policy requirement to guarantee the time-stamp at the time of logging the message.
timestamp-records-limit	10000			Maximum number of message records to time-stamp in one batch. If the number of message records in a single batch exceeds 70 % of timestamp-records-limit value, a warning is logged in proxy.log.
timestamper-client-connect-timeout	20000			The timestamper client connect timeout in milliseconds. A timeout of zero is interpreted as an infinite timeout.
timestamper-client-read-timeout	60000			The timestamper client read timeout in milliseconds. A timeout of zero is interpreted as an infinite timeout.
timestamp-retry-delay	60			Time-stamp retry delay in seconds when batch time-stamping fails. After failing to batch time-stamp, the timestamper waits for the time period defined by "timestamp-retry-delay" before trying again. This is repeated until fetching a time-stamp succeeds. After successfully fetching a time-stamp, the timestamper returns to normal time-stamping schedule. If the value of "timestamp-retry-delay" is higher than the value of the central server system parameter "timeStampingIntervalSeconds", the value of "timeStampingIntervalSeconds" is used. If the value of "timestamp-retry-delay" is zero, the value of "timeStampingIntervalSeconds" is used.
archive-transaction-batch	10000			Size of transaction batch for archiving messagelog. This size is not exact because it will always make sure that last archived batch includes timestamp also (this might mean that it will go over transaction size).
max-loggable-message-body-size	10485760 (10 MiB)		20971520 (20MiB)	Maximum loggable REST message body size
truncated-body-allowed	false			If the REST message body exceeds the maximum loggable body size, truncate the body in the log (true) or reject the message (false).
clean-transaction-batch	10000			Maximun number of log records to remove in one transaction.
archive-grouping	none			Archive file grouping, one of 'none', 'member' (group by member), 'subsystem' (group by subsystem).

archive-encryption-enabled	false			If true, archive files are encrypted using OpenPGP (GnuPG)
archive-gpg-home-directory	/etc/xroad/gpghome			GPG home for archive file signing (and default encryption) keys
archive-encryption-keys-config				Configuration file for member identifier to OpenPGP key id mapping. Per-member keys can be used when grouping is by 'member' or 'subsystem' (subsystems use the member's key). See [UG-SS] for details.
archive-default-encryption-key				Default OpenPGP key id for archive encryption (if not defined, the primary encryption key is used)
messagelog-encryption-enabled	false			If true, message bodies are stored to the database in an encrypted format
messagelog-keystore				Path to the keystore containing the key used in messagelog encryption
messagelog-keystore-password				Messagelog keystore password
messagelog-key-id				Identifier of the messagelog encryption key

SOAP

The logged SOAP headers are the X-Road message headers listed in Chapter 2.2 of the X-Road Message Protocol document [PR-MESS], as well as the representedParty extension of the X-Road protocol described in the extension's XML schema. The security server targeting extension for the X-Road message protocol [PR-TARGETSS] or the Security Token Extension [PR-SECTOKEN] will not be included in the message log.

REST

The logged HTTP headers are the X-Road HTTP headers listed in Chapter 4.3 of the X-Road Message Protocol for REST document [PR-REST], including the security server targeting extension for the X-Road message protocol [PR-TARGETSS]. All other HTTP headers are excluded from the message log.

The file is deployed during X-Road installation and by default has following content (see exact cron specifications) [CRONHOW]:

#!/bin/sh
* * * * * xroad curl http://127.0.0.1:8084/managementservice/gen_conf 2>1 >/dev/null;

The parameter regulating the timing of global configuration generation is the cron expression at the start of the last line (* * * * *), which means that global configuration generation is invoked every minute by default.

Note. OpenJDK 8 on RHEL 7 supports ECDHE key agreement protocol starting from RHEL 7.3. In RHEL 7 versions prior to RHEL 7.3 only DHE cipher suites are supported.

6 Adding command line arguments

Sometimes you may need to provide command line arguments for Security Server, Central Server or Configuration Proxy, in order to override some parameters. For example if you wish to increase Java's maximum heap size, you can do it with the properties file /etc/xroad/services/local.properties. The file is also included in the backup archive file when taking a configuration backup of either Central Server or Security Server.

6.1 The configuration file

The file /etc/xroad/services/local.properties replaces the file /etc/xroad/services/local.conf starting from X-Road version 7.

The local.properties file's contents consists of key-value pairs such as XROAD_SIGNER_PARAMS=-XX:MaxMetaspaceSize=100m. Notice that you cannot use quotes in the values. If you have multiple values for one key, use space to separate the values e.g. XROAD_SIGNER_PARAMS=-Xmx100m -XX:MaxMetaspaceSize=100m. Also notice that with local.properties you can only add new parameters and override old ones – you cannot remove existing default parameters.

Example of /etc/xroad/services/local.properties with modifications that override the default Java memory parameters for Security Server:

XROAD_PROXY_PARAMS=-Xms200m -Xmx1024m

Example of /etc/xroad/services/local.properties with modifications that override the default Java memory parameters for Central Server:

XROAD_JETTY_PARAMS=-Xms200m -Xmx1024m

All possible properties to adjust in this file:

Property	Details
XROAD_PARAMS	Parameters for all processes
XROAD_SIGNER_PARAMS	Parameters for the Signer
XROAD_ADDON_PARAMS	Parameters for all addons
XROAD_CONFCLIENT_PARAMS	Parameters for the Configuration Client
XROAD_CONFPROXY_PARAMS	Parameters for the Configuration Proxy
XROAD_JETTY_PARAMS	Parameters for the Central Server
XROAD_MONITOR_PARAMS	Parameters for the Environmental Monitor
XROAD_OPMON_PARAMS	Parameters for the Operational Monitor
XROAD_PROXY_PARAMS	Parameters for the Security Server
XROAD_PROXY_UI_API_PARAMS	Parameters for the Security Server's admin API
XROAD_SIGNER_CONSOLE_PARAMS	Parameters for the Signer Console

6.2 Legacy configuration file support in X-Road v7

If you have upgraded from X-Road version 6 to version 7, you might still be using local.conf script file with legacy parameters (non XROAD_ prefixed parameters), which is considered deprecated in X-Road version 7. The legacy file local.conf will not be included in the configuration backups anymore – the new file local.properties will be included instead, therefore it is strongly recommended migrating to the new local.properties file.

The legacy file local.conf will still be supported along with the legacy parameters. It is possible for both files to exist side-by-side. In this case the values from local.properties are appended first and then the local.conf file gets executed as a script afterwards. Notice that if your local.conf script contains new XROAD_ prefixed parameters and old legacy parameters, the new XROAD_ prefixed parameters will always be preferred.
