Ubuntu 9.10 Home Encryption Performance

Filed under
Ubuntu

The home encryption feature ended up being disabled in Ubuntu 9.04 unless a special boot parameter was used, but it has now reappeared in Ubuntu 9.10.

The home encryption support offered in Ubuntu 9.10 comes with many bug fixes and usability issues compared to what was offered in Ubuntu 9.04. The change-log that details all of the work that has went into the eCryptfs package since Ubuntu 9.04 can be found on Launchpad.net. Additionally, this feature now provides AppArmor rules, enabled shell scripts for localization/translations, and now the SWAP partition is encrypted if using the home directory encryption feature. In Ubuntu 9.04 the SWAP partition was never encrypted if using the home encryption feature, which lowered the level of security that was offered and its benefits. With Ubuntu 9.10 the EXT4 file-system is being used by default, which should lead to difference performance figures from our earlier test runs. As a result we have carried out a new round of Ubuntu home directory encryption testing under an Ubuntu 9.10 development snapshot. This feature is exposed both through Ubuntu's Ubiquity installer as well as through Ubuntu's alternate install CD.

FOSS Events: LCA and systemd.conf

  • 5 great linux.conf.au talks (that aren't about Linux)
    linux.conf.au, otherwise known as LCA, is one of the world's longest-running open source events. LCA has been held in a different city around Australia and New Zealand almost every year since 1999. Despite the name, linux.conf.au is a generalist open source conference. LCA hasn't been just about Linux for a long time. Rather, the conference focuses on everything to do with open source: the software, hardware, and network protocols that underly it. LCA also has a strong track on free and open culture, exploring how open source interacts with science, government, and the law.

  • The End of Gmane?
    In 2002, I grew annoyed with not finding the obscure technical information I was looking for, so I started Gmane, the mailing list archive. All technical discussion took place on mailing lists those days, and archiving those were, at best, spotty and with horrible web interfaces. The past few weeks, the Gmane machines (and more importantly, the company I work for, who are graciously hosting the servers) have been the target of a number of distributed denial of service attacks. Our upstream have been good about helping us filter out the DDoS traffic, but it’s meant serious downtime where we’ve been completely off the Internet.
  • Pwnie Express makes IoT, Android security arsenal open source
    Pwnie Express has given the keys to software used to secure the Internet of Things (IoT) and Android software to the open-source community. The Internet of Things (IoT), the emergence of devices ranging from lighting to fridges and embedded systems which are connected to the web, has paved an avenue for cyberattackers to exploit.
  • The Software Supply Chain Is Bedeviled by Bad Open-Source Code [Ed: again, trace this back to FUD firms like Sonatype in this case]
    Open-source components play a key role in the software supply chain. By reducing the amount of code that development organizations need to write, open source enables companies to deliver software more efficiently — but not without significant risks, including defective and outdated components and security vulnerabilities.
