An iptables based firewall for systems running the Linux 2.4 or later kernel. Very flexible configuration allows the firewall to be used in a wide variety of firewall/gateway/router and VPN environments.   A bug that was supposedly fixed in Shorewall 3.4.4 was not fixed. Furthermore, the bug is present as far back as 3.2.6.  If HIGH_ROUTE_MARKS=No, then PREROUTING and OUTPUT marking rules are behaving as if TC_EXPERT=Yes was specified in shorewall.conf. In other words, these rules are being applied even if the connection has been marked as being associated with a particular ISP.  The symptoms in this user's case were that requests through ISP1 that were port-forwarded to an SMTP server were being replied through ISP2. The reason was that there was a tcrule which selected ISP2 for all connections from the SMTP server.  Errata patches as follows:  http://www1.shorewall.net/pub/shorewall/3.2/shorewall-3.2.10/errata/patches/Shorewall/patch-3.2.10-2.diff http://www1.shorewall.net/pub/shorewall/3.4/shorewall-3.4.6/errata/patches/Shorewall/patch-3.4.6-1.diff http://www1.shorewall.net/pub/shorewall/4.0/shorewall-4.0.2/errata/patches/Shorewall-shell/patch-shell-4.0.2-2.diff  The 3.2.10 patch applies to all 3.2 releases from at least 3.2.6 onward and to 3.4 releases 3.4.0-3.4.3 (with offset). The 3.4.6 patch will also work on 3.4.4 and 3.4.5 (again, with possible offset).  It is also possible to work around the problem by adding these two rules at the beginning of your tcrules file:  CONTINUE:P      0.0.0.0/0       0.0.0.0/0       -       -       -       - !0 CONTINUE        $FW             0.0.0.0/0       -       -       -       - !0

LIVE WEBCAST(Source: Symantec)  The lynch pin of a successful Business Continuity effort is a complete Disaster Recovery (DR) capability, the ability to quickly resume IT operations at a geographically remote location when needed. Symantec recognizes these obstacles and has built flexible cluster configurations and non-disruptive DR testing capabilities into its industry leading clustering technology, Veritas Cluster Server, that will enable customers to not only have a robust and cost effective HA/DR but also test their DR plans at times convenient to the data center team and in a way that won't impact production environments.

OpenSSI Clusters for Linux Leverages HP's NonStop Clusters for Unixware and various open source technologies to provide a full, highly-available SSI (Single System Image) clustering environment for Linux. Goals include availability, scalability and manageability.New features include several CFS performance enhancements and the integration of LVS-NAT. POSIX process groups and multi-threaded applications can now atomically migrate as a group. Also, processes can migrate while holding file record locks. New commands include 'fast' and 'fastnode'. Several files have been added to /proc/cluster for dynamic modification of nodedown detection parameters. Finally, a variety of bugs have been fixed.   OpenSSI 1.1.0 is a development release, and is not necessarily suitable for production use. The Red Hat 9 version should only be used for upgrading from OpenSSI 1.0.0. New installs should be done on Fedora Core 2 or Debian.  You can find our latest release here: https://sourceforge.net/project/showfiles.php?group_id=32541&package_id=131632

(InfoWorld) - Enterprises using the network-based firewall offered by Verizon Business will now be able to control it much as they would a firewall on their own networks. The global business services unit of Verizon Communications will let customers go outside the standard templates it has offered so far and tune firewall features to meet their specific needs. The company was set to announce the change on Monday at the RSA Conference in San Francisco. As business operations spread around the world through outsourcing and mobile work, the line between the inside and outside of a corporate network becomes more complicated. For U.S.-based organizations, Verizon Business sells the Secure Gateway Network-based Firewall as an alternative to IT departments installing and maintaining their own firewalls. The service runs on modules in Cisco routers in Verizon's network core. Since it rolled out the service about 18 months ago, the carrier has given customers a choice of templates for what they want the firewall to do. For example, one template might allow only e-mail packets to come in from the Internet. But the templates don't fit every enterprise need, said Eric Sorensen, senior group manager of secure gateway services at Verizon Business. For example, an automaker that gets parts from a third party may want to let nonemployees onto its servers, but only those logging in from a certain factory and using a particular application, Sorensen said. With the Secure Gateway Network-based Firewall (custom), an IT administrator can set that kind of rule, he said. The service includes a Web-based interface for making changes in real time. The standard edition with templates is still available. Most enterprises have balked at network-based firewalls because they don't want to give up granular control over their security, said Gartner Inc. analyst Alex Winogradoff. Verizon's new hands-on feature could help break down that resistance, he said. Handing off security to service providers follows the trend of enterprises letting carriers provide and manage their networks, Winogradoff said. Keeping firewalls in many locations up to date is not easy, he said. "It's a chore that is not part of the core business that enterprises want to be in," Winogradoff said. One thing that might worry enterprises about the network-based firewall is control over periodic updates to the underlying software. An IT manager worried about a new version of software would want to be able to keep using the older version until the problem was solved, Winogradoff said. The Secure Gateway Firewall is sold as a feature on top of a Secure Gateway port. A 1.5MbpsÂ port costs an average of $200 to start and $1,000 per month. The custom firewall option would cost $140 per month. Verizon Business hopes to offer the service to customers based outside the U.S. later this year. Also at RSA, Verizon Business will announce it is extending its denial-of-service protection system to Europe. Verizon DoS Defense Mitigation, which identifies and blocks attacks that use massive amounts of incoming traffic, is now available in 11 European countries, including France, Germany, Spain and the U.K., the company said. It plans rollouts in Canada, Latin America and Asia later this year.
