Infrastructure Linux News for Sep 29, 2001

  • IBM developerWorks: Improving the security of open UNIX platforms (Sep 29, 2001, 23:30)
    "Tracing modifications made to new system files with SGID/SUID flags is an extremely difficult task. But with enough experience and caution, system services and settings can be modified without changing standard file attributes (usually an administrator pays attention to the dates a file was created and modified). The following program traces changes made to all the files of a specified directory using an integrity test based on MD5 checksum, which prevents modifications from being masked."

  • DukeOfURL: Caldera OpenLinux Workstation 3.1 (Sep 29, 2001, 19:31)
    "Recently Caldera have been mired in controversy, with plans to switch from open source to a more common proprietary business model. They now have per seat licencing for their distribution, the antithesis of licensing models offered by almost every other distributor of Linux based operating systems. A stance that many postulate may hurt them in the long haul. After all, if Red Hat can pull off the new business model there isn't a reason for anyone can't. This latest release is built around KDE 2.1, and as such, contains a good many KDE development tools and the accompanying documentation. Some of the benefits being touted by Caldera include: software integration, default configurations, self hosting, secure software, system testing, and even OEM testing."

  • MachineOfTheMonth: Entertainment Software Series: DVD players for Linux and Video CD Recording (Sep 29, 2001, 15:32)
    "The real question is "Do I miss my DVD player?" The answer to that question is "I love my Linux box and the more things I can do on it, the more I love it." So sure I miss Dolby Digital 5.1 surround sound on a home theater system setup but I get more satisfaction out of watching a movie on my computer than a big home theater system. Why? Because it's open source. How? Because I compiled and installed it."

  • Linux Journal: You Can Get There from Here, Part 3 [LDAP Intro] (Sep 29, 2001, 11:29)
    "LDAP is an acronym for Lightweight Directory Access Protocol. I like to think of it as directory assistance for your network, a kind of net-enabled 411 service. With an LDAP server running on your, er, server, directory assistance will never be far away. Sound good? Strap in because this is a big topic. I'll get into some of the nittier and grittier stuff associated with LDAP later, but I know that you want to walk away from this with something that works, so this is the plan for today."

  • InfoWorld: Where the heart lies (Sep 29, 2001, 04:02)
    "Although it is true that writing open-source software is not on the same level as running into a collapsing building to save lives, it is true that electing to write open-source code is by no means a subversive activity. It is, in fact, a little slice of selflessness -- something that America applauds."
