Did anybody show up to last night meeting? Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

spamd
by brad May 20, 2013

May 20, 2013

Hi All, i've been getting more spam over the last couple of days. It appears spamd is not running on my ubuntu 10.04 server; however the headers of the spam messages have X-Spam-* flags. I'm not sure what might be adding the spam headers, perhaps its upstream (or clamav). I wanted to start using spam assassin, but that appears to crash when i run the following, which i dug out from the init scripts, sudo /usr/bin/perl -T -w /usr/sbin/spamd --create-prefs \ --max-children 5 --helper-home-dir --pidfile=/var/run/spamd.pid This line results in the following output: May 19 17:50:03.557 [8665] info: rules: meta test T_SUBJ_BRKN_WORDNUMS has dependency 'DKIM_SIGNED' with a zero score May 19 17:50:03.626 [8665] info: collectd: Insecure dependency in connect while running with -T switch at /usr/lib/perl/5.10/IO/Socket.pm line 114. May 19 17:50:03.726 [8665] info: spamd: server started on port 783/tcp (running version 3.3.1) May 19 17:50:03.726 [8665] info: spamd: server pid: 8665 May 19 17:50:03.729 [8665] info: spamd: server successfully spawned child process, pid 8743 May 19 17:50:03.733 [8665] info: spamd: server successfully spawned child process, pid 8744 May 19 17:50:03.736 [8665] info: prefork: child states: IS May 19 17:50:03.736 [8665] info: prefork: child states: II [1] 8665 alarm sudo /usr/bin/perl -T -w /usr/sbin/spamd --create-prefs --max-children 5 I'm not sure what 'alarm' means. I tried running it with debugging messages, none of which seemed useful. Below are the relavent heads from one spam message, X-Virus-Scanned: Ubuntu Server Edition amavisd-new at ithryn.com X-Spam-Flag: NO X-Spam-Score: 3.25 X-Spam-Level: *** X-Spam-Status: No, score=3.25 required=3.5 tests=[BAYES_50=0.8, HTML_MESSAGE=0.001, HTML_MIME_NO_HTML_TAG=0.377, MIME_HTML_ONLY=0.723, RCVD_IN_BRBL_LASTEXT=1.449, SPF_PASS=-0.1] autolearn=no Anyone have advice to get spamd running correctly? thanks, - brad

Announce: Change in tonight's WLUG meeting
by Chuck Anderson April 10, 2013

April 10, 2013

Sadly, Jim Gettys has been ill and will be unable to speak at tonight's meeting. We'll still meet and have an informal discussion and answer any Linux/FOSS support questions people have. We'll also raffle off some books and go out for pizza afterwards. I hope to reschedule Jim for a future meeting. ----- Forwarded message from Chuck Anderson <cra(a)WPI.EDU> ----- Date: Tue, 2 Apr 2013 15:02:27 -0400 From: Chuck Anderson <cra(a)WPI.EDU> To: wlug(a)wlug.org Subject: [Wlug] Announce: WLUG Meeting Wed 4/10 7PM Jim Gettys on Internet buffer bloat Precedence: list Reply-To: Worcester Linux Users Group <wlug(a)mail.wlug.org> Hi folks, The next Worcester Linux Users' Group (WLUG) meeting will be held at its regularly scheduled time: the 2nd Wednesday of the month, which is Wednesday, April 10, at 7PM. The location will be the WPI Campus Center, Mid-Centry Room 331. This month we will have Jim Gettys from Bell Labs talk about Internet buffer bloat. "Internet buffer bloat, by Jim Gettys (Bell Labs) VOIP and teleconferencing often perform much more poorly on today's Internet than the Internet of a decade ago, despite great gains in bandwidth. Lots of fiber, cheap memory, smart hardware, variability of wireless goodput, changes in web browser behaviour, changes in TCP implementations, and a focus on benchmarking Internet performance solely by bandwidth, and engineer's natural reluctance to drop packets have conspired to encourage papering over problems by adding buffers; each of which may introduce latency when filled. The mistaken quest to never drop packets has destroyed interactivity under load, and often results in actual higher packet loss, as TCP's congestion avoidance algorithms have been defeated by these buffers. The lessons of the "RED manifesto" of 1997 have been forgotten or never learned by a new generation of engineers." Wednesday, April 10, 7:00 - 10:00 PM WPI Campus Center, Mid-Centry Room 331 I will also be raffling off some more items. Afterwards, we will go out for pizza. See you there, Chuck President, Worcester Linux Users' Group http://www.wlug.org/ _______________________________________________ Wlug mailing list Wlug(a)mail.wlug.org http://mail.wlug.org/mailman/listinfo/wlug ----- End forwarded message -----
