    "With the advent of high-speed Internet links from Internet Service Providers (ISPs), it's easier for users to host services on their home computers. But what happens when your ISP connection goes down? An obvious solution is to have a redundant Internet connection from another ISP."

  • Chicago Tribune: Use Linux firewall to fend off hackers (Jan 25, 2002, 22:24)

  • EnGarde Secure Linux Security Advisory: rsync (Jan 25, 2002, 21:48)
    "There are instances where rsync does not do proper input validation, allowing an attacker to write NULL-bytes to somewhat arbitrary locations of the stack. This may potentially lead to a remote root shell."

  • Conectiva Linux Security Announcement: rsync (Jan 25, 2002, 21:46)
    "Sebastian Krahmer from SuSe did an audit on the rsync source code and found several vulneranilities regarding the use of signed integers. Some variables could receive a negative value, and this was a condition that was not expected by the program. A remote attacker could exploit this to execute commands on the rsync server."

  • Obelix versus MobiliX: Legal Response Online Now (Jan 25, 2002, 20:37)
    "The legal response (PDF, 22 pages in German) is online now . The document describes the origin of the names Obelix (from 'obelisk') and MobiliX (from 'mobil' and 'UniX'). Many well known names are used to show how widespread the suffix 'ix' is in the IT business, e.g. often UniX derivates are named by this scheme. This is followed by an analysis of the pronounciation and spelling of the words Obelix and MobiliX, and whether they can be mistaken from members of the IT business or not. As a conclusion the charge is considered void."

  • BulmaLUG: Journal File Systems under Linux (Jan 25, 2002, 19:46)

  • The Register: Net patent tax - W3C publishes new advice (Jan 25, 2002, 18:48)
    "The RAND addition was stalled after the issue blew up at the end of September, with open source developers advocating the formation of an alternative to the W3C, if royalty-bearing licenses became an option. Now, with the input of Bruce Perens and Eben Moglen, a compromise has been reached."

  • SuSE Security Announcement: rsync (Jan 25, 2002, 18:16)
    "There exist several signedness bugs within the rsync program which allow remote attackers to write 0-bytes to almost arbitrary stack-locations, therefore being able to control the programflow and obtaining a shell remotely. These bugs have been fixed."

  • WIRED: Can WINE Ferment Move to Linux? (Jan 25, 2002, 17:37)
    "'More programs fail to run under WINE than successfully run,' [CodeWeavers' Jeremy] White said. But he said that WINE 1.0 will feature a lot of 'very important internal changes,' including an easier and more efficient application installer."

  • W3C: Current Patent Practice (Jan 25, 2002, 16:39)

  • osOpinion: Debunking Mac Myths (*NIX Edition) (Jan 25, 2002, 14:56)
    "Apple is hoping that the introduction of its new iMac and digital hub suite will convince Windows folks to drop by their local Apple store and make the switch. This strategy is well and good, but I think the Apple marketing machine could and should target another segment of the population for conversion: the Linux/UNIX user."

  • Adam Wiggins: Open Source on the Business Desktop (Jan 25, 2002, 05:29)
    "My employer, TrustCommerce, has been making a slow transition to open source desktops over the past year. Today we have removed almost all proprietary software from the company desktops, and we're doing business just as well (and arguably better) than before. Surprisingly, the majority of our customers are not members of the open source community (though a good portion of them are). In fact, most of our customers have no idea what the the terms "Open Source" or "proprietary" mean, and would think we were crazy if we took Richard Stallman's suggestion and rejected the many .doc and .xls files that are sent to us each day."
