[edit] Introduction

The following release notes provide an overview of the ClarkConnect 4.3 release. All users should read this document, but special attention should be made by users upgrading their systems to this release.

[edit] What’s New

The Office Edition and Enterprise Edition products have now merged! Unlimited mailboxes are now included in the Enterprise Edition and this includes full groupware support. The full list of changes is available in the developer change log — highlights include:

[edit] Important Notes for 3.x Users

The 3.x to 4.x versions is a major upgrade, so please review the Software Package Notes below. For the impatient:

If you have configured the ClarkConnect system via the web interface only, the configuration files will automatically be upgraded. If you have made changes via the command-line or the Webmin tool, please double check your custom configuration after an upgrade.

[edit] Upgrading

Version 4.x supports upgrades from ClarkConnect 3.0 and later. Upgrades from version 2.x (or systems originally installed with 2.x) are not supported. When you run the ClarkConnect installer, make sure you select the upgrade option (see adjacent screenshot). As with any upgrade, please backup any critical data.

In addition, users who have installed third party software packages or used the command-line apt-get tool to install software should also run the following commands:

apt-get update
apt-get dist-upgrade

[edit] Upgrading from 4.0 / 4.1 / 4.2 to 4.3

If you are upgrading from 4.0, 4.1 or 4.2 and are familiar with the Linux command-line environment, you can perform the upgrade over the Internet. Run the following commands:

apt-get update
apt-get install cc-upgradeto43
apt-get clean
apt-get update
apt-get dist-upgrade

After performing the upgrade, a reboot is required.

[edit] Known Issues

  • Blank screens on first boot with some types of hardware
  • Some legacy Dell/Megaraid RAID cards are not supported.
  • Localization is incomplete.

[edit] Deprecated Packages

The following key packages are no longer included in this version:

2.x to 3.x

  • dhcp (replaced by dnsmasq)
  • lvm (replaced by lvm2)
  • modutils (replaced by module-init-tools)
  • perl-Mail-SpamAssassin (replaced by spamassassin)
  • policy
  • pop-before-smtp (replaced by postfix)

  • privoxy (replaced by adzapper)

[edit] Software Package Notes – 4.2 to 4.3

[edit] Kolab

The kolabd service (daemon) has changed to ldapsync. This was done to avoid some confusion with Kolab Groupware. The ldapsync service does two tasks:

  • synchronizes LDAP settings for other applications
  • synchronizes mail accounts with LDAP (if the mail software is installed)

[edit] OpenVPN

If you have been experimenting with OpenVPN in previous versions (beta via , the upgrade to 4.3 may impact your settings. Please verify your configuration after performing an upgrade.

[edit] Kernel

Some Intel Gigabit network cards have changed drivers (from e1000 to e1000e). If your network cards are not detected on your first reboot, please run the kudzu hardware detection tool from the command line. The kernel upgrade from version 4.2 is optional, but you can upgrade it with the following commands:

apt-get update
apt-get install kernel

The last command will show a list of available kernels. Select your preferred kernel and install it, e.g:

apt-get install kernel#2.6.18-93.cc

[edit] Software Package Notes – 4.1 to 4.2

[edit] Content Filter (Beta)

If you installed the experimental version of the content filter in version 4.1, you must perform a re-install of the software. From the command line, run the following:

  • rpm -e cc-dansguardian-av cc-dansguardian dansguardian dansguardian-blacklists dansguardian-phraselists dansguardian-av
  • mv /etc/dansguardian-av /etc/dansguardian-av.old
  • apt-get update
  • apt-get install cc-dansguardian-av cc-dansguardian

[edit] Kernel

The kernel has been upgraded from 2.6.9 to 2.6.18. This means that you must reboot your system after the upgrade. In addition, multiprocessor (SMP) support is now included in the base Linux kernel — you no longer require the kernel-smp package. If you have more than 4 GB of memory installed, please install the special PAE kernel — apt-get update; apt-get install kernel-PAE

[edit] VPN

Both the PPTP VPN and the IPsec VPN servers have been moved in the menu system. You can now find these features under the Network configuration.

[edit] Software Package Notes – 4.0 to 4.1

[edit] Mail – Antispam

Antispam training has changed. Please review the Antispam Training in the User Guide.

[edit] Mail – SMTP

The mail server will now reject e-mail messages to invalid addresses earlier in the mail processing. This will reduce the resources required for the antivirus and antispam services. This change will be reflected in the mail server reports.

[edit] Software Package Notes – 3.x to 4.1

[edit] Backup/Restore

The backup/restore system settings now includes the user database. It is not possible to restore settings from an old release on to the current release.

[edit] Firewall

The firewall has changed to accommodate the new Hot LAN and Blocking features. Custom firewall rules configured via the command line may no longer function as expected. In addition, the advanced firewall module is no longer installed by default.

[edit] Mail – Antivirus

ClamAV is now included in ClarkConnect. Sophos antivirus is no longer supported.

[edit] Mail – Antispam

The configuration for the antispam engine has changed. Please review the configuration settings after an upgrade. You may also want to install the additional Dspam software.

[edit] Mail – POP/IMAP Server

The POP/IMAP mail server has gone through some significant changes. Please read the Migrating Mail to ClarkConnect 4.x document

[edit] User Manager

If you are upgrading from a previous version, go to the web-based administration tool to review the user manager. You may be required to perform one or more of the following actions:

  • Reset a password (important)
  • Change a user’s first and last name

In addition, the following changes have been made:

  • The Community Edition allows a maximum of 10 mailboxes.
  • Shell access is no longer an option.
  • The dual-passwords used in 3.x are no longer supported.

[edit] Webmail

The default webmail system in ClarkConnect 4.x is powered by Horde. Please review the documentation for how to access the webmail system. If you are upgrading from a previous release, you will have to install this software package after upgrading (if desired). Access to the old webmail system is still available.

[edit] Web Proxy

The web proxy server only accepts requests from the local LAN. If you have virtual LANs or other LANs behind your ClarkConnect system, you will need to edit the proxy server configuration file.

[edit] Web Proxy Reports

The web proxy and content filter reports have been replaced.
