SpamAssassin false positives on DATE_IN_FUTURE_96_Q?
by Gilbert E. Detillieux 23 Feb '16

23 Feb '16

I mentioned this problem at the last round-table session, but didn't get a solution, so I thought I'd post it here, just in case anyone has any suggestions to offer. I'm still seeing a whole bunch of false positives in SpamAssassin, since an update was installed in mid-September on a CentOS 5.7 system, for a rule called DATE_IN_FUTURE_96_Q, which is only supposed to be triggered when the "Date:" header has a date that is 4 days to 4 month ahead of the date in the "Received" header that has the _smallest_ difference in date. Here are the headers from the latest e-mail I've received with this false-positive. (I've stripped out irrelevant headers, for the sake of clarity and simplicity.) From topfivestories(a)messagent.itworldcanada.com Mon Nov 14 07:50:13 2011 Received: from mail.messagent.itworldcanada.com (mail.messagent.itworldcanada.com [207.112.10.80]) by palladium.cs.umanitoba.ca (8.13.8/8.13.8) with SMTP id pAEDoAxV028594 for <gedetil(a)cs.umanitoba.ca>; Mon, 14 Nov 2011 07:50:12 -0600 Date: Mon, 14 Nov 2011 08:50:13 -0500 X-Spam-Status: No, score=-0.3 required=5.0 tests=BAYES_00,DATE_IN_FUTURE_96_Q, HTML_MESSAGE,RP_MATCHES_RCVD autolearn=no version=3.3.1 X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on palladium.cs.umanitoba.ca Note that I'm calling spamd via the spamass-milter on a system running sendmail. Note also, that in the above example, the only "Received" header was the one generated by my own server. (I've had other false positives, however, with multiple "Received" headers, all of which were within seconds of the time in the "Date" header.) Any ideas? -- Gilbert E.

Winnipeg Harvest donations from December meeting - thank you!
by athompso＠muug.mb.ca 04 Apr '12

04 Apr '12

Thanks to the generosity of our members, we were able to donate three large boxes’ worth of non-perishable food items to Winnipeg Harvest in December 2010. The text of the thank-you letter we just received (see attached) is as follows: January 5, 2011 Manitoba UNIX User Group Attn: Adam Thompson Dear Friends of Harvest, We here at Winnipeg Harvest want to thank the Manitoba UNIX User Group for your support of helping those less fortunate in our community. Over the last few months 743 pounds of food was donated to the food bank. Your donations will go into hampers that will help Winnipeg Harvest feed more than 58,000 people each month, half of those being children. On behalf of the entire team at Winnipeg Harvest, thank you for helping us fight hunger and feed hope in Manitoba. We look forward to working with you again in the future. If I can ever be of assistance, please don’t hesitate to contact me by phone at 982-3670 or by email at tori(a)winnipegharvest.org. Yours truly, Tori Webber Development Associate Winnipeg Harvest Inc. So, thanks again. See you all in another six (6) days, at our next meeting on January 11th, 2011. -Adam Thompson athompso(a)muug.mb.ca

[New security bug:] X.Org: Screen lock bypass
by Adam Thompson 27 Jan '12

27 Jan '12

Of interest to anyone running X workstations outside physically secure environments (like their basements), I should think. This announcement is from Gentoo, since everyone else appears to have embargoed their information on this temporarily. (Which in turn suggests that a major vendor is vulnerable and hasn't patched it yet.) This should only affect recent distros (e.g. Fedora 16, but not 15). There's a workaround suggested in Red Hat bugzilla #783039. Best information I can find about it until MITRE releases the CVE: http://who-t.blogspot.com/2012/01/xkb-breaking-grabs-cve-2012-0064.html.

Fwd: HotPar '12 Submission Deadline Approaching
by Gilbert E. Detillieux 24 Jan '12

24 Jan '12

FYI... -------- Original Message -------- Subject: [Board] HotPar '12 Submission Deadline Approaching Date: Sun, 22 Jan 2012 21:20:02 -0800 From: Lionel Garth Jones <lgj(a)usenix.org> To: info(a)muug.mb.ca, gedetil(a)muug.mb.ca I'm writing to remind you that the submission deadline for the 4th USENIX Workshop on Hot Topics in Parallelism (HotPar '12) is approaching. Paper registration (abstract submission) is due Tuesday, January 24, 2012, 11:59 p.m. PST. Full paper submission is due Tuesday, January 31, 2012, 11:59 p.m. PST. There will be no extension of the deadlines. http://www.usenix.org/hotpar12/cfpb HotPar '12 will bring together researchers and practitioners doing innovative work in the area of parallel computing. Multicore and multithreaded processors are pervasive, and core counts are increasing. This trend is driven by limits on energy consumption in computer systems and the poor energy performance of increasingly complex uniprocessors. Parallel architectures can potentially mitigate these problems, but larger core counts will be successful only if languages, systems, and applications can take advantage of parallel hardware. Navigating this change will require new parallel programming paradigms, new methods of application design, new structures for system software, and new models of interaction among applications, compilers, operating systems, and hardware. We request submissions of position papers that propose new directions for research or products in these areas, advocate non-traditional approaches to the problems engendered by parallelism, or potentially generate controversy and discussion. More information and submission guidelines are available at http://www.usenix.org/hotpar12/cfpb We look forward to receiving your submissions. Sincerely, Hans-J. Boehm, HP Labs Luis Ceze, University of Washington HotPar Program Co-Chairs hotpar12chairs(a)usenix.org -------------------------------------------------------------- Call for Papers 4th USENIX Workshop on Hot Topics in Parallelism (HotPar '12) June 7-8, 2012, Berkeley, CA http://www.usenix.org/hotpar12/cfpb/ Paper registration (abstract submission) due: Tuesday, January 24, 2012, 11:59 p.m. PST Paper submission due: Tuesday, January 31, 2012, 11:59 p.m. PST --------------------------------------------------------------

Please submit all work by January 23, 2012, 11:59 p.m. http://www.usenix.org/webapps12/cfpb Like the inaugural WebApps '10 and '11, WebApps '12 seeks to attract cutting-edge research that advances the state of the art, not only of novel Web applications but also of infrastructure, frameworks, tools, and techniques that support the development, analysis/testing, operation, or deployment of those applications. Possible topics include but are not limited to: * Storage for Web-scale applications * Techniques for testing and debugging * Novel strategies for fault tolerance or high availability in Web apps * The Web as an emerging platform in new application areas * Making Web apps social and integrating with social utilities, e.g., Facebook, Twitter, Google+ * HCI techniques related specifically to Web apps * Measurement, modeling, workload generation, and other tools to aid experimental research on Web apps * New and unusual app features or implementation techniques * Media delivery applications and infrastructure * Client-side libraries, toolkits, plug-ins * Server-side frameworks * Languages and language engineering advances relevant to Web app development * Deployment substrates and technologies (cloud computing, infrastructure as a service, testing as a service, etc.) WebApps '12 will consist of a single track of refereed papers and, new this year, a set of short paper demos. Papers with practical significance and/or working prototypes will be preferred over purely theoretical results. Short paper demo submissions must have a working prototype. Submitted papers must be no longer than 12 pages for regular papers and 6 pages for demo papers, including figures, tables, and references. For more details on the submission process, advice on how to prepare a competitive paper, and templates to use with LaTeX, Word, etc., authors should consult http://www.usenix.org/events/webapps12/cfp/requirements.html WebApps '12 will take place June 13-14, 2012, in Boston, MA. It is a co-located event that occurs during USENIX Federated Conferences Week, which spans June 12-15, 2012. I look forward to receiving your submissions.

simple name service
by Dan Martin 23 Jan '12

23 Jan '12

The network seems connected. I'd like to be able to refer to the machines by their names. I have up to 9 machines connected, each with a distinct manually set IP address (not counting some virtual machines in Parallels on the Mac). The machines have a variety of OSs. I may get a registered domain name, but not for about a year from now. For now I would like the simplest (read laziest) solution possible. I am hoping that there is a very simple way to run a DNS service privately on the network as opposed to changing /etc/hosts on a number of machines. Most of what I have seen makes this look more than trivial. I am running Suse (I think Suse 10) on my gateway, but hoping I could follow directions for setting up on Ubuntu at http://lani78.wordpress.com/2008/08/09/setting-up-a-dns-for-the-local-netwo… I don't want to do anything more complicated than that for the time being. Suggestions? is there a lazier way? -Dan Dan Martin GP Hospital Practitioner Computer Scientist ummar143(a)shaw.ca (204) 831-1746 answering machine always on
