To accomplish the upgrade to version 4.1.x the prior version 3.0.26 needs to be installed. To install the version 3.0.26 please follow the steps "Get Package List", "Get Packages" and "Install".
Please follow the steps "Accomplish Upgrade to Version 4.1.x" if the version CBS 3.0.26 is installed. Please read the release notes to the appropriate version.
The web server can grant individual rights for the use of CGI or PHP within the share options. With this update the PHP safe mode can be handled within the file share options.
This update contains a new kernel with a driver update to version 1.1.5 for Adaptec AACRAID based (PERCx) Controller.
Collax Server use the scripting language Perl and the Perl libraries. The huge number of modules included in the packet perl-modules are going to be apportioned into single perl-module packets. There are no changes resulting if using Collax server services, a system update can be run faster.
Please note: If developing and integrating an ISV application for the Collax Server Platform, handling the dependencies for building and installing needs to be modified for the single perl modules. The dependency only to the packet perl-modules could not be sufficient anymore.

For identifying unsolicited bulk email the additional filter SpamAssassin is used. With this update the version 3.2.5 will be installed and corrects the qualification of e-mails sent by Outlook(tm) as false positives.
The link monitoring tool checkes links and switches to functional links if the main link does fail. After a system reboot the start of the link monitor could lead to a CPU load of 100%. This is going to be fixed within this update patch for the link monitor.
Configuration files of Collax server are used for easy managing of one or more servers. From this update on the validation of the files has been tightened to increase the usibility Please check the imported files that were saved before version 3.0.0 via the new AJAX gui and correct the values if necessary. The gui will give the information, if any value needs to be modified.
The setting "Canonicalize sender address" can be used to rewrite internal email addresses to addresses that can be reached externally.
If you create multiple mail domains, the address is always rewritten to the first matching rewrite address. The order in which mail domains within the LDAP directory are considered for matches can change, though, and is more or less random.
You can work around this problem by configuring the email clients such that the external address is always used for outgoing e-mail.
When the authentication of users is made against a non-local database, e. g. ADS/PDC, please be aware that the user "mailadmin" does not exist on the ADS/PD, because this user is used internally in CBS. Otherwise problems will occur, e. g. during the creation of local mailboxes.
When using the web-content filter with custom lists which contain URLS and/or domains and/or expressions, it is possible that the filter is not working correctly, and doesn’t block anything. In order to fix this problem please save each list and activate the configuration.
The NTLM authentication scheme that is usually used by windows client software is now enabled when the support for windows networks has been enabled. It is no longer necessary to enable it separately.
Please note that for being able to authenticate with NTLM against a Windows 2003 Server Service Pack 1 has to be installed.
If the above error message is displayed when surfing over the web proxy and rules are used to limit the web traffic, please check the rules configured under "Settings -> Filter -> Web-Content Filter -> Rules". Load every individual rule by double-clicking the entry. If the message "Please specify at least one URL or Cobion list" is displayed, specify the respective list to be associated with this rule or enable the menu item "All". If no such error message is displayed, you can return to the list of rules by clicking "Cancel". If you changed any of the rules, activate the configuration.
To establish an initiating VPN tunnel an additional VPN link with connection method "dial-in" was always required. With this update VPN tunnel with connection method "Always" don't presume a VPN "dial-in" link anymore.
It can happen, that hylafax denies facsimiles from callers. In this case, you should deactivate fax spamlists. Please follow this description: The left menu shows Messaging/Fax/General. Deactivate 'Switch on number control'. You can save now and activate the configuration.
It is possible, that problems occur when a FritzCard-AVM-PCMCIA and another different PCMCIA-card are used at the same time. In this case please call the support hotline.
In some cases it was possible that faxes were not submitted correctly so that the header was cut or missing wholly.
If you experience these problems you should set the maximum receive rate to a value below 14.400 Bit/s. You can set this in the MODEM-Page on the GUI.
In order to be able to use the Sedlbauer-ISDN-Card for an analog connection to a provider, the following must be set in "Additional Hayes-Options" : "AT&FS14=10S15=0S18=1&E" followed by the MSN of the ISDN-Card.
The configuration used within CBS works properly with the most commonly used modems. Nevertheless, it is possible that specific modems cannot be initialized correctly. At the moment, analog links are not used as fallback by the "Link monitoring" .
The AntiVir-WebGate does not yet support HTTPS which means that HTTPS-connections are not possible in combination with AntiVir-WebGate. So at the moment HTTPS-traffic bypasses this filter.
The print service itself offers its services over the Internet Printing Protocol (IPP). This protocol is directly supported by MacOS X and most Linux distributions. Printers with Ethernet ports can be added to the queues on the Collax Business Server. These printers are also exported over the printer support of the SMB/CIFS server and can be addressed directly over IPP by Windows clients.
From update 3.0.12 on, replication logs of the MySQL database are no longer written. If you need these logs, enable the option "log-bin" in the file "/etc/mysql/my.cnf.template" by removing the comment sign preceding this option. Subsequently, run a full configuration over the web interface.
To integrate the Collax Server for authentification in a Windows server network, the SMB/CIFS service can be used. It is important, that this service has at least one policy group containing a local network.
Exporting virtual hosts via FTP is only possible with IP-based virtual hosts. Name-based virtual hosting with FTP is not possible due to limitations in the FTP protocol itself.
The initial setup of the mailboxes is in conjunction with the option "Alternative namespace". This means that you should decide which format you want to use before the mailboxes are created. When this option is enabled the folders Sent, Draft and Trash are below the folder Inbox. When this option is disabled the folders Sent, Draft and Trash are on the same level as the folder Inbox. When you change the option "Alternative namespace" after the creation of the mailboxes, the Webmailer will show up a error in the following form: "Query: CREATE "INBOX.Sent" and "Reason Given: Invalid mailbox name". The name of the folder can vary.
In order to accomplish NTLM-Authorization with an imported group, this group must be a global group on the AD-Server and must be the primary group of the user.
There are limitations in the functionality of bandwith management if used in combination with link fallback. If a main link connection fails bandwith management cannot be ensured if the connection changes to an indirect link like a VPN or route link.
It is not possible to use VPN connections with asymmetric routes if the system is both a router and an IPSec gateway.
This is because IPSec accumulates a checksum of the IP header contents. With asymmetric routing, the IP addresses of the links - over which the data is transmitted and received - do not correspond.
It is not possible to establish multiple IPSec connections for the same networks and the same two security gateways. This is due to how OpenSWAN works internally (keyword "eroutes". Those having trouble with OpenSWAN know what is meant here; a deeper analysis would go beyond the scope of these release notes).
You can set up a GRE-tunnel over the IPSec-tunnel to bypass this problem.
The encryption algorhithm SHA2 is used in VPN tunnels. In kernel 2.6 this encryption method causes errors in the service OpenSwan and the VPN tunnel crashs. For that reason this method can't be chosen for VPN links on Collax Server until it is fixed. As an alternativ the method SHA1 can be chosen. Please note that the encryption method needs to be changed and the other VPN gateway modified. The upgrade will choose SHA1 if SHA2 was setup before.
The base DN of the LDAP directory cannot be changed retroactively through the GUI. The reason for this is that not all directory data can be rebuilt from the configuration.
Although data is lost, the easier way is to delete the files in the "/var/lib/openldap/openldap-data" directory, and then recreate the directory.
To achieve that, proceed as follows:
Log on to the system as "root" .
Stop the LDAP server. You can do this either through the GUI (System -> Services) or with the "/etc/init.d/openldap stop" command.
Use "cd /var/lib/openldap/openldap-data" to change to to the database directory of the LDAP server. Verify that you are in the right path with the "pwd" command.
Delete all files in the directory with "rm *.bdb" .
Change the base DN of the directory in the GUI.
Activate the changes. You will get an array of error messages explaining that data cannot be written into the LDAP directory. When the activation is completed, the LDAP server should restart with the changed configuration.
Execute the "/usr/lib/akconfig/scripts/ldif.gen config" command to transfer the data from the system configuration into the LDAP directory.
Beware: all passwords of all users will be lost after having changed the base DN. You have to enter them again via the Admin GUI.
If a transparent web proxy is activated and the Antivir Web virus scanner is activated together with the "Show download status" option, the download no longer works properly. The download progress is displayed but does not change; after a short while, the browser displays an error message indicating that antivir.webgate cannot be found. To make the download work with the progress bar, enter the proxy in the client or disable the "Show download status" option.
After updating OXtender to version 4.2.19 when creating an appointment the created appointment is correctly displayed in creators calendar but is shifted two hours ahead in other participants' calendar.
Solution: Install OXtender 4.2.19 on one of your Windows workstations and copy the "zoneinfo" subdirectory to: C:\Programs\OPEN-XCHANGE\OXlook to the workstations where "zoneinfo" is missing.
