Check File System

Before upgrading the server a check of the file system should be carried out. The file system check is available in the boot menu of the server. To lead the check by, a display and a keyboard must be connected to the server and afterwards a restart needs to be executed. After loading the BIOS the file system check can be selected in the boot menu. As a result the file system is checked and suitable state messages are displayed. If the file system is in order the server starts and the upgrade can be carried out. Technical questions to the file system check can be placed to your certificated Collax partner or to the support team by Collax.

Duration of Upgrade

Depending on your existing server installation up to 320 software components will be downloaded and replaced. So the total duration of the upgrade process will take between 45 minutes and 180 minutes.

New in this Version

Security: Firewall Tftp Connection Tracker

If services use undeterminable ports for the data transfer connection tracker are used for the firewall to establish and track such connections. With this update the connection tracker for the trivial file transfer protocol (tftp) can be activated in the firewall when required. Connections about this protocol can be set up and logged with it.

Add-on Software: New Version of Collax Virus Protection

The virus scanner Collax Virus Protection offers comprehensive antivirus protection for email services. Within this Collax system update the scanner is updated to the newest version.

The options for “Email disinfection”, “Damaged Email” and “Alerts” are omitted from this update on. Emails can additionally be copied to quarantine (mail queue for hold mails) if they had been cleaned or before they shall be deleted.

Attention: Please start a manual pattern update by clicking the button “Get Updates” at the bottom of the form in Settings -> Filter -> Collax Virus Protection, Tab Mail. This update is necessary to start the services successfully.

System Management: Monitoring of Services

All enabled services of the Collax servers are checked on their working mode, f.e.: running or stopped. The status is indicated in the form “System-> monitoring / evaluation-> state-> services”. If the active monitoring is switched on, the services are also tested qualitatively. The status whether the function of the service is all right, or whether problems occured during operation have appeared (Bsp: OK, WARNING, CRITICAL). Configuration -> Monitoring” is indicated in the new column “Test”.

System Management: Extension of System Information

Up to now information about CPU, RAM and hard disks were displayed as system information. From this update it is possible to gather detailed graphic information about file system, hard disks and network interfaces.

System Management: Logging of Firewall Rules

It is regulated within the Firewall matrix which network connections running thru the Collax server are permitted or are forbidden. To simplify the logging of these regulated network connections the option “Logging for the Firewall Matrix” can be set now in the form “Settings->Networking->Firewall->General->Options”. Up to now this setting needed to be activated for each single connection. The logging of permissible or forbidden connections will be applied in general on all firewall rules, explicitly or implicitly, and thereby it eases the use and the reporting of the rules.

System Management: Extended Active-Directory Integration

Up to now the integration of Collax server in Microsoft ActiveDirectory was used to authenticate the users against in the ActiveDirectory. This function is going to be extended with this software version to read user-related data from the ActiveDirectory, this data is going to be used within the Collax services to provide a full centralized user management via Microsoft ActiveDirectory. This function can be activated via Settings -> Usage Policy -> PDC/ADS -> Enable Active Directory proxy.

Hardware: iSCSI Initiator

iSCSI makes the use of the SCSI protocol on a TCP/IP network possible. From this version the function of the controller, the iSCSI initiator, is implemented in the Collax server. With the iSCSI initiator storage devices in the network (iSCSI Targets) are integrated transparent as local storage devices. To the functions of the iSCSI initiator counts the target discovery, to integrate storage devices fast on the network, as well as the possibility of the authentication to establish a reliable connection to the iSCSI-Target.

Hardware: Driver for 10GB Network Interface Cards

The driver for 10gigabit network interface cards will be implemented within kernel version 2.6.25.20. These driver support the following NICs: Chelsio 10Gb Ethernet, Chelsio Communications T3 10Gb Ethernet, Intel® 10GbE PCI Express, Intel® PRO/10GbE PCI-X, S2IO 10Gbe XFrame NIC, NetXen Multi port (110) Gigabit, Sun Neptune 10Gbit, Tehuti Networks 10G, Broadcom NetXtremeII 10Gb.
