Database variables

Important.png Note:
See following wiki pages for the syntax of access to the configuration database entries from the command line Access from the Command Line and a db command tutorial


SME Server comes with the most used parameters set as variables in its internal configuration databases. These variables are used to store values to be used in the final configuration files. Please, read the SME_Server:Documentation:Developers_Manual:Section2 to understand the template and database process.

These variables are useful to configure your system more easily, as you do not need to modify configuration files directly for most common cases. It also makes it possible to administer the server through its server-manager as the database variables are used to set and change configuration parameters. After editing, the configuration files must be regenerated and affected services need to be restarted.

For example, suppose you need to increase "memory-limit" in php.

You would simply execute these commands at the server console: 

db configuration setprop php MemoryLimit 64M
expand-template /etc/php.ini
/etc/init.d/httpd-e-smith restart

The first line changes the value for the memory limit of PHP, the second line regenerates the configuration file and the last line will reload Apache (and subsequently also PHP as this is configured as a module of Apache).


Warning.png Warning:
Database parameters are case sensitive so take great care when typing at the server shell because no error messages are given should you make a typo.


The database system is based on a flat file system, but you should never edit them directly. Instead you should use the db command. More details on using the database system can be found in the SME Server Developer's Guide.


Setting db variables to default values

Important.png Note:
Use of 'config' is a shorthand version for 'db configuration' and therefore only works with the configuration database


Any db variable that has a default value can be reset to the default by deleting the variable entirely, then re-initializing the default database values as follows: 

config delprop <key> <prop>
/etc/e-smith/events/actions/initialize-default-databases

Delete a property value

To delete the property 

db accounts delprop <key> <prop>

Reset a property value

To reset to an empty value 

db accounts setprop <key> <prop> ''


Warning.png Warning:
Database parameters are case sensitive so take great care when typing at the server shell because no error messages are given should you make a mistake.


Concept of the signal-event command

Due to the efforts of the developers, you can further simplify the commands using the signal-event proccess.

For full details see SME_Server:Documentation:Developers_Manual:Section2

Overview of database variables

The next section describes the standard variables defined on SME Server. Please update this list with new standard variables in future SME Server versions.

The tables below have three columns. The first is the variable, the second is the target variable (located in the final configuration file), and the third is the default value.

A lot of the variables can be set using the server-manager but some can not. For example the variable DomainMaster for samba is not important here, because this can be set through server-manager. On the other hand, the variable RecycleBin is important, because it is not accessible through the server-manager.

Configuration files may use database values from a single configuration key, or may use multiple keys. The latter is the case for the /etc/rc.d/init.d/masq configuration file. This file takes it values from multiple database keys such as squid and masq.

It is also possible that multiple configuration files use the same key. An example of this is the httpd-admin key. This key has a variable TCPPort which is used in multiple files (/etc/httpd/admin-conf/httpd.conf and /etc/services).

ConcurrencyLimitPerIP INSTANCES_PER_IP 12
ProcessMemoryLimit ulimitdata 128000000


Information.png Tip:
The notes on the concurrency limits noted under IMAPS also apply here. See below.


  • only for SME Server 9
Affected file: /var/service/imap/config
Variable Target Default
AllowPlainText if set to disabled, dovecot will still listen on port 143, but will only accept TLS connexions, even from the local networks enabled/disabled, default is enabled

IMAPS (imaps)

Usage 

db configuration setprop imaps variable value
signal-event email-update
Affected file: /var/service/imaps/config
Variable Target Default
ConcurrencyLimit INSTANCES 2000
ConcurrencyLimitPerIP INSTANCES_PER_IP 12
ProcessMemoryLimit ulimitdata 128000000


Information.png Tip:
You can see if you are running out of the number of available connections in your log file /var/log/dovecot/current (for sme8, it is /var/log/imap/current and /var/log/imaps/current) and look for messages like the log extract below where the ConcurrencyLimitPerIP was set to 12. A 13st connection was attempted and was denied. 
@400000005396a2d215b40d9c imap-login: Info: Maximum number of connections from user+IP exceeded (mail_max_userip_connections=12): 
user=<stephane>,  method=PLAIN, rip=90.84.144.xxx, lip=192.168.xx.15, TLS


Information.png Tip:
Mobile devices have a tendency to frequently disconnect and connect from the network. When this disconnect happens, the sessions on the server are not always immediately cleaned up (they get cleaned up after a time out of some minutes). When the email client reconnects, they create new network connections and you get into the situation that these new connections get denied because of the concurrency limit. On the mobile device this may be noted as a "Unable to connect to server" message.


Information.png Tip:
Some email clients use a separate connection per imap folder, so the concurrency limits may occur for users that have many imap folders.


Dovecot

  • Only for SME Server 9

With smeserver-dovecot installed, 4 services in the configuration DB are used

imap and imaps are used to be backward compatible with e-smith-imap (and are used to control the TCPPort of the service, and if it's accessible from local network or from the internet)

dovecot is now the main service entry in the configuration DB. It's used to control various optional features of dovecot


Usage 

db configuration setprop dovecot variable value
signal-event email-update
Affected file: /var/service/imaps/config
Variable Target Default
AdminIsMaster if enabled, the admin user will be a master user, and will be able to login as any user. To do so use user1*admin as login and the admin password to log as user1 enabled/disabled, default is disabled
FullTextIndexing will turn on or off the full text indexing. When this option is enabled, a first search in an IMAP folder will trigger indexation. Next searches will be much faster. Read this page before enabling this option enabled/disabled, default is disabled
LogActions will turn on or off extra logging (flag change, move, copy etc…). !! Warning !!: enabling this can generate a huge amount of logs enabled/disabled, default is disabled
Quotas will report the actual used space and the remaining one if the user has a quota limit enabled/disabled, default is enabled

IPTables firewall (masq)

Usage 

db configuration setprop masq variable value
signal-event remoteaccess-update
Affected file: /etc/rc.d/init.d/masq
Variable Target Default
Logging Logging most
Stealth Stealth no


Information.png Tip:
Special case is TCPPort and UDPPort from any DB key.

Any Db key named "TCPPort" or "UDPPort" affect masq file.

Currently the following keys are included in masq:

TCPPort:

httpd-admin - sshd - smtpd - ssmtpd



Additional information on customizing iptables

Create a custom-named service definition in the configuration database. 

db configuration set <servicename> service

Apply your desired firewall restrictions to any existing SME 'service' or to a custom-named service that you have created. Combine a custom-named service with port-forwarding to create customized firewall rules. 

db configuration setprop <servicename> TCPPort <portnumber>
db configuration setprop <servicename> TCPPorts <portnumbers>
db configuration setprop <servicename> UDPPort <portnumber>
db configuration setprop <servicename> UDPPorts <portnumbers>
db configuration setprop <servicename> status enabled|disabled
db configuration setprop <servicename> access public|private
db configuration setprop <servicename> AllowHosts a.b.c.d,x.y.z.0/24
db configuration setprop <servicename> DenyHosts e.f.g.h,l.m.n.0/24

Effectuate the changes you have made

Miscellaneous Other DB Variables

Important.png Note:
This is meant to be an easy place to add db variable information if you don't have time to put it into the correct section(s) above. You can find most of the template fragments affected by a given db variable if you execute: 
cd /etc/e-smith
fgrep -lR variable templ*/* | less

where variable is the name of the variable using correct capitalization

Note that any command listed here is to be executed on one line!
