Please note the hardware requirements if you want to do an upgrade to version 4.1.x.
If your Collax Business Server version is below 2.0.0 please make sure that you do a backup of the intermediate Version 1.18b. To upgrade to the current version a further intermediate step to version 2.5.2, 3.0.6 and 3.0.26 will be accomplished.
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.
Spam-filter blacklists make sure that e-mails from specific addresses get a high spam score and thus will be classified as spam. The list "dsbl.org" has gone and will be removed automatically with this update. "sbl-xbl.spamhaus.org" and "ix.dnsbl.manitu.net" will come along.
Unter Policies -> Certificates -> X.509 Certificates you can create and download 'Certificate Signing Requests'.
A CSR (Certificate Signing Request) is a message which is required to get a certificate from a certification authority.
New is the possibility to export certificates in the format 'DER' which is used by some mobile devices to set up a secure connection.
Under Network -> Links -> Configuration the connections can be configured. By creating a 'VPN' Link with a 'Pre Shared Key' it is with UTF-8 support now possible to use e.g. special characters or characters of other languages in the Pre Shared Keys.
The now Bacula-based backup system has been completely overworked and can be found under System Configuration -> Backup.
New is the support of tape changers and storage libraries, the possibility of tape rotation and a direct administration of jobs and media.
With "Restore" single elements can be restored, as well as retrieving of status information of single jobs.
After a full system crash "Recovery" allows it to re-put the Collax Server into service.
Under "System and maintenance it is possible to retrieve status information of the backup system, e.g. finished or running jobs as well as administratively tasks like adding/labeling media or the managing of storage devices.
With the backup wizard plans for backups can be created step-by-step.
If you want to convert an already etablished backup to the new backup system you can do this with the backup migration wizard.
Collax Extended Backup offers the possibility to backup clients with different operating systems.
To make this possible a client-software has to be installed on the system. The software for Windows is directly downloadable over the Collax Server. The client-software for Linux and Mac can be downloaded over the Bacula Website. The required configuration file for the client-software can be directly downloaded over the Collax Server.
Also it is possible to configure a monitor access for the clients to the server. With this monitor low-level-information of the involved system components, particularly the director and the storage-daemon, can be viewed.
The optional software-modul 'Collax Mail archive' has been developed to enable companies to comply with the requirement to archive business-relevant e-mail for 10 years.
The archive can be split into several volumes whose size can be determined arbitrarily. It is possible to generate ISO files from the individual volumes and burn them on storage media. That can be found under System Operation -> E-Mail Archiving -> Archiv status.
Events stored in the systems log file can be qualified and displayed within a clearly arranged table with the Event Monitor. From this update on settings for the Event Monitor can be optimized within the form Settings -> System Operation -> Log Files -> Event Monitor
Now events can be relayed to an other Collax Server, additional events can be also be accepted from other Collax server to gain a central view of system and securityy related events.
In the form Network -> Firewall -> Port Forwarding services can be forwarded to an destination port. For the forwarding of services with multiple sub-services (e.g. multiple ports) a destination port can no longer be set from this update on. The field Destination port can be left empty and as a result the source ports with sub services are forwarede correctly.
With Mail-to-Fax it is possible to send a e-mail as a fax. If the mail-to-fax-gateway was activated and then fax globally has been deactivated, the mail-to-fax-gateway has not been deactivated too. This is fixed with this update.
The forms of the previous afbackup backup system Targets, Plans, Restore and the Backup Wizard are going to be marked with "(obsolete)" from this Collax update on. The obsolete forms still can be used coevel to the new backup system based on Bacula until the settings will have been changed.
To convert the settings of plan types HDD, Smb, Cifs, NFS or Tape the Backup Migration Wizard can be used easily. After the conversion the obsolete forms and settings are removed. Please convert to the new backup system as soon as possible.
Note: The form "Restore (obsolete)" is kept remaining for restore purposes of existing data backups.
If using CVP web filter an error regarding cvpweb.key could occur after an update. This is going to be fixed within this software update, the license file is checked after each activation.
Notification of the Collax Virus Protection had been sent by the Mailer Daemon since last update. This is fixed with this update, notifications for CVP will be sent from the local system administrator "root".
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.
In the current Version of Open-Xchange the iCal interface broken.
