Release Notes - ClarkConnect 3.1

[edit] Architecture

The core packages in ClarkConnect are built on the Red Hat Enterprise Linux 4 Source RPMS. However, we have made a few changes:

• We decided to put aside the udev implementation (see RHEL 4 Release Notes). The implementation is a nice feature for desktop systems, but not important for server systems.
• The MySQL package was split into two different RPMS: mysql and mysql-client.
• The distcache feature in the Apache web server was disabled.
• PPTP, firewall and peer-to-peer patches were added to the kernel.
• Legacy Megaraid support was added to the kernel (see Software Package Notes below).

[edit] What's New

Major features in 3.1 include:

• CentOS 4 core
• LAN and system backup
• Significant firewall speed improvement
• New intrusion detection reports
• New intrusion prevention features
• Peer-to-peer bandwidth shaping
• PPTP pass-through mode
• Content filter phrase list configuration

[edit] Upgrading

Version 3.x supports upgrades from ClarkConnect 1.1 and later. 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.

Some software required conversion utilities and name changes. You should double check the following after your upgrade.

• Changes to the User Manager
• Running services on your system
• Apache web server configuration
• ProFTP server settings
• Firewall rules
• PPTP usernames
• Photo Gallery configuration
• New features and modules!

In addition, users who have installed 3rd party software packages on their systems should also run the following commands in order to install legacy library support (if any):

apt-get update
apt-get dist-upgrade

[edit] Upgrading from 3.0

If you are upgrading from 3.0 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-upgradeto31
apt-get update
apt-get dist-upgrade

Important post-upgrade notes:

• A kernel upgrade is performed during the upgrade -- this is required
• A reboot is required when upgrading from 3.0 (due to a kernel upgrade)
• Any active login to the web-based administration tool will still display the old version. This does not have any impact on the operation of the system -- the version will change the next time you login.

[edit] Known Issues

• A harmless but unsightly warning will appear on systems without a floppy disk.
• Legacy Dell/Megaraid RAID cards may not be supported (see Package Notes)
• Upgrading from 3.0 to 3.1 over the network generates a warning message for the Postfix mail server.

[edit] Deprecated Packages

The following key packages are no longer included:

• 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)
• raidtools
• reiserfs-tools (replaced by reiserfs-utils)
• snortsnarf (replaced by cc-snort-report)

[edit] Software Package Notes

[edit] Dell/Megaraid RAID

Older Megaraid (Dell) RAID controller drivers were removed from the Red Hat Enterprise Linux kernel. We have re-enabled legacy driver support in ClarkConnect 3.1. Older hardware includes:

• Dell PERC (dual-channel fast/wide SCSI) RAID controller
• Dell PERC2/SC (single-channel Ultra SCSI) RAID controller
• Dell PERC2/DC (dual-channel Ultra SCSI) RAID controller
• Dell CERC (four-channel ATA/100) RAID controller
• MegaRAID 428
• MegaRAID 466
• MegaRAID Express 500
• HP NetRAID 3Si and 1M

[edit] DHCP Server

The ISC DHCP server has been replaced by the Dnsmasq DHCP server. The upgrade will save your old configuration file (/etc/dhcpd.conf) to /etc/dhcpd.old. However, any DHCP leases configured on a previous install will not be preserved.

[edit] Kernel and Firewall Upgrade

To accommodate changes to the bandwidth management tools, a kernel upgrade to version 2.6.9-19.cc or higher is necessary. The kernel upgrade is done automatically with one exception: if you have manually disabled automatic kernel upgrades from the command line, then please review the instructions here.
