About SME Server

SME Server is the leading Linux distribution for small and medium enterprises.

SME Server is freely available under the GNU General Public License and is only possible through the efforts of the SME Server community. However, the availability and quality of SME Server is dependent on meeting our expenses, such as hosting costs, server hardware, etc.


Thanks

The development team would like to thank all of those involved in this release. However, this distribution cannot continue with the current level of support. More people are required to help with bug triage and verification testing.


This release contains many new features, all released updates for SME Server 7.3 and fixes for many reported problems. Upgrades will be available by CD, the Software Installer and command line.


Upgrades

  • Always perform a backup prior to major system upgrades
  • An upgrade will preserve the existing data


Changes in this release

Installer

  • Fix grub label to keep consistent with the SME Server brand.

Mail system changes

  • Introduce a web interface to configure the pseudonym "visible" property (internal|external)
  • New feature now allows a "catch all" situation where you have the ability to redirect "@virtualdomain1.com" to user "joe".
  • Fix the "Ugly" log messages (Use of uninitialized value) when spam checking results in 0 hits.
  • Emails sent to a null address like ""@domain without the username part are now rejected.
  • qplogsumm is a optional feature that should be disabled by default.
  • A request that the log information is reduced with the default loglevel setting of 6 in qpsmtpd.
  • Support for sending mail to ISP via Secure SMTP
  • Enable the auth plugin for local lan connections
  • Migrate (remove) "ordb.net" from the RBL lists to prevent mail bouncing.
  • Remove blackhole.securitysage.com as service no longer in use.
  • Remove sbl-xbl.spamhaus.org from default lists and use a more improved list in zen.spamhaus.org.

Console

  • Improved validation will check password on first enter password screen before verifying if too simple then asking to verify and proceed to configuration of server.
  • Passwords should be validated for strength on first entry rather than waiting for the second confirmation entry.
  • The console should validate passwords using the common method, using esmith::util::validatePassword
  • The last item in the server console, "Exit from server console", is removed as it is redundant.
  • Display frames in console server-manager. When browsing server-manager through console pressing 'H' goes to http://localhost/server-manager

Backups

  • Backups now use dar which enables a backup to consist of more than 2GB of data to a workstation in any of the following supported methods:

cifs, nfs or local usb disk. It also gives the option to set how many rotating backups are required and allows to split size of backup to DVD size.

  • Removed 'restore from desktop' functionality
  • The error codes from tar are now logged, in line with flexbackup, and do not cause a backup to fail.
  • A Iomeage USB REV-drive was by default mounted in /media as a cdrom device. It is now automagically mounted as an usbdisk so it can be used as a backup device without manual intervention.
  • Set dar compression to default to gzip
  • dar backup to be less verbose in panel
  • Correct mounting for usb disks
  • no compression for ogg media files
  • Make dar use defined list of directories to backup
  • Remove obsolete smbfs backup method


Localisation

As part of a major update with translations we have added six new languages and made it much easier to add other languages in the future.

We now support the following languages in the server-manager: Danish, Dutch, English, French, Greek, German, Hungarian, Indonesian, Italian, Portuguese, Slovenian, Spanish and Swedish.

We have made major strides to assist the non-English community by using a tool called pootle. This is a web based translation tool that will allow new languages to be added and existing languages to be more easily maintained.

We have cleaned up a lot of the packages as a part of getting them towork with pootle. Another big change as part of this upgrade is the switch from ISO-8859-1 (Latin) charset to UTF-8 (Universal) charset, this will allow us to support languages that don't use latin characters (like Greek).

Other fixes include updated translations for the existing languages.

Software Installer

  • smeextras repository added, it is used for building the installer and ISO
  • The yum-update event now includes the yum-import-keys action to allow users to update yum packages and configuration without rebooting, which enables updating when there is a compatibility problem.
  • Correct yum-update-dbs action to adjust yum service properly.
  • The BaseURL property has been removed for repos with mirrorlists.
  • The message "This system is up to date." is displayed if no updates are available.

Webmail

  • Horde, imp, turbo and ingo have been updated to the latest versions
  • Support the ability to save user kronolith free/busy information to the LDAP database.
  • Servers with a custom template for 110AppRegistryHorde found webmail no longer worked.
  • The name of the webmail installation is now configurable. To use * config setprop horde Name xxxx ; signal-event email-update.

Server manager

  • The name of the log file being viewed via the Server Manager 'View log files' is now displayed as the first line.
  • Disabling the daily update check in the server-manager did not stop the check4updates task sending mail to the server administrator.
  • Server-manager > printers > add printer * now advises users to avoid certain names and descriptions as this causes printer state to be incorrect.
  • Fix the Unknown heading in server-manager after an update.
  • Fix inconsistency within the navigation.xx files which no longer adds extra spaces and newlines in panel headers.
  • The Anti-virus (ClamAV) panel text was updated to remove the word 'entire' as this could be misleading.
  • Allow server-manager to successfully create a one character user account.
  • After adding a user and trying to set password via server-manager or user-password using the ";" sign you encountered a "white screen of death". This was due to the version of perl-Object-Persistence being used.
  • Remove the last 'pleasewait' message as it is no longer needed.
  • The button to add a new user in the server-manager was missing due to a problem with the free/busy code in usermanager causing the panel to exit.

Other fixes and updates

  • Updated Samba resolves various file sharing problems
  • The length of an Ibay name is now configurable via maxIbayNameLength
  • The Samba "unix extensions" are turned off for Mac compatibility

  • Suspicious string scanning (supscan) has been disabled due to being CPU and I/O intensive and prone to producing false positives.
  • The audittool script has been updated to also identify modified events.
  • If a custom motd was used this could have been sent with the smolt data, now only the version from e-smith-release is sent.
  • The wrong URL was shown for the smolt profile, it has been updated to http://smolt.contribs.org/
  • Patch djbdns around TCP bug: http://alkemio.org/dns_transmit-bug.html
