Remeber Mismatched Domains for Thunderbird (and Firefox)

Useful extension, especially for those self-sign SSL certs: rmd for thunderbird too.

95% Spam

From O’Reilly’s Radar, 95% of their incoming mail is spam: Another War We’re Not Winning: Us vs Spam.

  • 829,890 SMTP connections made to our two gateway mail servers
  • 904060 attempted message deliveries
  • 49194 messages accepted (I think this is actually a little high due to a configuration problem with our Zimbra server.)
  • 94.6% of all messages were rejected

I thought this was the most interesting comment for Paul Vixe:

every potential smtp improvement or replacement that could do anything to actually stop spam, has been systematically patented. the crap that’s left isn’t going to do any good. we’re headed for walled gardens.

If SMTP had been patented, modern email might have been still born. By extension the digital commons created with SMTP is now suffering greatly because software patents prevent better usage models.

Balancing the need of innovation against public good is hard, however 20 years+ for a software patent is just too long.

A Look at Conary

Conary: An innovative second-generation package manager

I agree with the review that all the conary jargon is very confusing.  Seems to be worth the effort though as conary might provide in the long run a good system for not just building software appliances, but a useful system for managing a large number of Linux systems.

Puppet on Ubuntu Howto

Configuration Automation & Centralized Management With Puppet on Ubuntu from HowtoForge.

Puppet seems easier to setup the cfengine, hopefully it will be as easy to use.  Using puppet to push up apt-get updates seems like a worthy task. Hopefully someone puts together a howto on the best practice for that.

VMware Tools and Windows Terminal Server

I was trying to find out how to prevent users for accessing the VMware tools in a Windows 2003 Terminal Server. Seems this is actually a security bug.

I’m running Windows Terminal Server on top of Debian with VMware Server. My solution was to add an explicit DENY permissions to the WTS_Users group I had added to the TS machine’s “Remote Desktop Users” group. I changed these permissions in the locations mentioned in the securityfocus message.
