Main server stable, mail backlog shrinking

A CPU overheating problem with Chebucto's main server appears to have been resolved with some re-routed ductwork carrying refrigerated air directly to the two CPUs. The main server, which sorts mail, controls user mail access, and hosts most of the Chebucto Community Net website, has been in stable use since 2003. Since last weekend it had been shutting down unexpectedly, with each reboot taking up to three hours to check and correct hard disk errors before users could login. No ready cause for the shutdowns could be found and staff and volunteers have been working around the clock, swapping out hardware, trying to diagnose the cause of the problem.

A backlog of email, 1.35 million messages at its peak early Tuesday evening (August 19, 2008), representing around one day's volume of email, is being delivered as fast as it can be processed. At the same time, a rise in incoming spam mail, a "spam storm", means more new mail for the mail scanning servers to tag and the main server to have to deliver. At current processing rates it is estimated all queued mail should be delivered by some time Thursday morning (August 21).

The main server was upgraded in early July with two new faster CPUs and more memory. While it is currently running stable, plans are to replace it with a more powerful 4 CPU Enterprise-class server sometime in the near future.

UPDATE: 8 PM, August 20, 2008: The mail queue has now dropped to just over 800,000 messages, or about 60% of a normal day's mail. Today around 1.4 days worth of mail has been processed so far - the mail processing needing to keep up with today's "spam storm" surge of junk mail as well as process the queued mail.

Chebucto Wireless update!

The Chebucto Wireless project is an ambitious design to bring secure low-cost high-speed wireless internet access to Metro residents. There has been interest in the project from community nets and other groups across Canada.

There has been zero development money from any outside source. All work on the wireless project has been in addition to the regular technical maintenance that Chebucto requires to keep operating.

The Chebucto Community Net now brings non-profit high-speed Internet to the metro Halifax area with a mesh network of wireless nodes hosted by users themselves.

Chebucto Wireless offers free public access to local metro and government websites and full Internet access to Chebucto Plus level memberships, currently $100 per year for individuals.

The areas to be served by the new wireless access will be determined by the residents of metro themselves. There's a map here.

Chebucto is looking for residents able to host wireless nodes, the cornerstone of the network, and when we get enough nodes in a neighbourhood, we can look at bringing network access where it is needed. A node sign-up form is online here.

The Chebucto Office does not recommend using the Internet Explorer web browser for any use except for accessing Microsoft's own Windows Update page. The popular web browser has been repeatedly successfully targetted by virus writers in particular seeking to break into home computers to use them for criminal purposes such as sending out spam, sending out viruses to break into other computers and being used to disrupt services on other computer systems.

After many reports about vulnerabilities for Microsoft Outlook and Outlook Express email programs, and the constant stream of user complaints about randomly altered program settings and difficulty using the program, the Chebucto Community Net Office and the Chebucto Technical Committee recommend our users do not use either Outlook or Outlook Express as their email program.

Keeping Microsoft Windows up to date is also very important. Windows XP users should have Service Pack 2 installed. All Microsoft Windows users should make a point of using Internet Explorer to visit the Microsoft Windows Update site at least once a month and download all critical updates.
