Broadcast Radio Engineer (or facsimilie thereof!)

by Mims Research

Hello all, Not sure if I've made my request on this list or not. Sorry if it's a repeat. Is there someone here who can help a non-profit organization work on a non-commercial full power radio license project? I am on the BOD of a non-profit that is considering an application for such and we could use a bit of help. Replies off list are fine. TIA, Marie email: mimsresearch(a)gmail.com

Charcoal grilling with liquid oxygen.

by joel d

At pizza we were talking about other web videos of people doing entertaining and dangerous things. The Mythbusters' disappearing cement truck is hard to top. Here was my favorite example, this guy uses 3 to 5 gallons of liquid oxygen to start your charcoal grill. He does it in shirt sleeves with a 5 gal bucket. Don't try this at home. http://www.doeblitz.net/ghg/ Joel

Possible sendmail attack?

by Dick Goodman

I have four servers on 3 different DSL lines running RedHat 7.3 with sendmail 8.11.6 I was on vacation at the time, but mid-day (13:00) on January 9th all of them started behaving wierdly. Instead of the occassional email, perhaps 95% of all incoming emails now show in the log as follows: Jan 9 09:41:17 bach sendmail[25179]: NOQUEUE: mail5.schaeffer.com [24.106.95.27] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA Jan 11 00:02:12 bach sendmail[14018]: NOQUEUE: h11009.upc-h.chello.nl [62.194.11.9] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA Jan 11 00:10:44 bach sendmail[14127]: NOQUEUE: bay0-omc2-s35.bay0.hotmail.com [65.54.246.171] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA Jan 11 00:13:23 bach sendmail[14148]: NOQUEUE: root@localhost did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA Jan 11 00:13:50 bach sendmail[14151]: NOQUEUE: 84.95.106.53.cable.012.net.il [84.95.106.53] did notissue MAIL/EXPN/VRFY/ETRN during connection to MTA The first one is legitimate mail, the others appear to be spam Much of the 50K pieces/month of spam I get are being trapped at the server in this manner before even getting to my spam filters (a good thing), but while some legitimate email is getting through, some is being rejected with this kind of message. Does anyone (a) have any idea what's happening here (b) have any idea how to fix it. Need more info? Just ask. Dick

REMINDER: Upcoming Meeting Thurs Jan 7, 2007

by Andy Stewart

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI Everybody, This is your monthly reminder (hand generated) regarding our upcoming WLUG meeting, to be held on Thursday, January 7th, 2007, at 7:00 PM in the Access Grid Room on the WPI campus in Worcester, MA USA. Many of you have suggested some good topics in our recent email threads. I propose that this meeting be a round table discussion of those and any other topics of interest. I'll bring my new laptop for discussion as well. It is a Linux Certified LC2464T running Kubuntu. However, I hope somebody has a DVI-SVGA adapter which I can borrow for the meeting, since I don't yet have one. Since this is my first experience with a Debian type of distribution, I could offer my first impressions. More info here: http://www.linuxcertified.com/linux-laptop-lc2464t.html If the discussion runs dry, ask me if I passed my Amateur Radio technician exam (which I'm taking on Wednesday). I'm curious to see what I can do with this and Linux. I can also give an update on the kernel device driver that I'm writing for the Delcom USB I/O demo board. I am planning to do a full presentation on this sometime soon, after I get more stuff working. A couple of simple features are working right now. Perhaps I'll do this for either the February or March meeting. More info here: http://www.delcom-eng.com/productdetails.asp?productnum=802004 As always, we'll adjourn to the Tech Pizza Restaurant on Highland Street for some discussion afterwards. All are welcome to attend! See ya later, and Happy New Year!

Must one be a REAL pro? The software is basically the same, but the product goals are different. You can run any kind of installation on either, but you won't get finger-pointing support and a long lifetime from Fedora which means you'll need to upgrade the OS every year or so to keep on top of security issues and bugs that are fixed, unless you want to fix things yourself. RHEL gives you 5 or more years of support. I can give a brief update on the current events in Fedora-land if anyone is interested. There are lots of interesting things happening right now, like the merger of Core and Extras, and the opening up of Core to all Fedora contributors.

Hi again, I think a discussion of how to set up firewall, router, and QoS on a Linux box would be very useful. Using Smoothwall is easy and all, but real understanding is of course better.
