ipwhois.rfc-ignorant.org and SpamAssassin

Looking at some logs, I noticed a bunch of entries for dns queries failing to things like: lame server resolving ‘14.182.8.69.ipwhois.rfc-ignorant.org. After some digging around on Google, I found a mailing list post from rfc-ignorant.org announcing the removal of the ipwhois.rfc-ignorant.org zone.

Looking at the SpamAssassin docs, this the right line to put in your local.cf to disable this particular test:
score RCVD_IN_RFCI 0

Yay, fewer log messages to look at every day.

Printing a mirror image

If you’ve ever had the need to print a mirror image of a document (ie, text to put on a teleprompter), you know there’s no easy option in Microsoft Word to do it for you. And you’ve searched the web to find that the only choice is some rare versions of the HP DeskJet drivers that have “Mirrored Output” options. Don’t be fooled, there is another way!

If you’ve got an HP LaserJet, go download the PostScript driver for it. Install them. Then, we you go to print, in Printer Properties, Click the Advanced button. Expand the PostScript Options section and set Mirrorer Output to Yes. I’ve done this with both a 4100 and an 8150, so it’s probably fairly common among the newer LaserJets.

You are probably asking yourself how, or even why, I figured this out. Well, one of the people around here does video production and bought a low tech teleprompter set up last year. Of course, I write down how to do this, so I spent 45 minutes this afternoon figuring it out.

My brain hurts

More survey greats:

  • possibly renting out portable USB ports. this would help with the transferring of memory from one computer to the next whether it be our own in our room, the ones in the lab, or someone elses.
  • I consider the services offered excellent. No complaints. It would be nice if you had a stapler physically attached to the table so that we do not have to go searching for one after we print.
  • Provide wireless routers to every URH dorm room, so that every URH dorm room could have wireless access to the University network.

3 more days.

Quite Apropos

This article on /. links to a WaPo article on MSNBC about cell phones on campus. The stats they mention are not from the WaPo article, and they aren’t the same as what we are seeing in our survey so far.
The cell phone vs. room phone dilemma is an interesting one, 911 service and general coverage being the biggest problems.

Annual Technology Survey

We are running our annual technology survey, and the same issues that always come up are happening, just like clockwork:

  • “You don’t have application X and I need it for class Y (or just because)!”
    • 9 times out of 10, we have the application, or something very similar. SSH is a perfect example, we’ve got 2 different clients and still people are asking for it.
    • AutoCAD is another common request. We have the regular AutoCAD 2005, but we don’t have the Inventor version that requires a high end 3D video card.
  • “NetTechs are slow!” and “The NetTechs are the greatest thing since sliced bread!”
    • Both these comments can’t be true, but if person A only needed help during opening week, when we are slammed with requests, while person B needs help every other week and has a tech on the same floor…Well, you get the picture.
  • “More wireless internet in the dorms!”
    • We are working on this as fast as we can, adding hotspots to many areas this year and this summer. But, wireless will never replace the wired URHNet connection in the rooms, so don’t ask. And if you don’t know why it won’t, either do some research or ask someone who has dealt with large scale wireless deployments.
  • “The computers in the labs are slow and sucky” and “Having fast, reliable computers in an always open lab is great, keep up the good work!”
    • Similar to the nettech comments, these both can’t be true. Apparently replacing computers every 4 years isn’t often enough for all people. It’s still nice getting compliments.

And, of course, there are just the classic responses:

  • To a question about what additional programming would be nice on our in house cable channel: “More porn like girls gone wild and stuff.”
  • “you guys kick ass
    the network here at school is probably the best i’ve ever connected through. i know it kicks other school networks ass. Lastly i’m very satisfied with how fast problems get fixed if there ever are any. i like u guys u make things run”

Puzzles and Deals

Every year for Christmas gifts from Alisha’s grandparents we get a puzzle or two. For some reason, they never seem to be easy ones. This year was no different. I didn’t get a good picture of the first one, but this is probably the best one. Not too tough, but not easy. The second one was much worse. I’m not sure how much time Alisha spent on it, but quite a bit more than I did.
Cropped round puzzle
This weekend I helped Jim pick up a nearly brand new 42U Dell server rack for the school district. We don’t really have a place to put it right now, but it was such a good deal we couldn’t pass it up.

More pictures of puzzles and the rack.

And, when I got back to the house today, the garage door wouldn’t open. I assumed it was frozen down, but it wasn’t. I came inside and the light on the wall switch was blinking continously. It would open using the wall switch, but not the remote or the HomeLink transmitter in my truck. I don’t think we have a manual for it anywhere, so I went searching the web. I found a discussion area talking about Craftsman door openers with someone else describing the exact same symptoms. The reply was to press and hold the lock button for 3 seconds, the constant blink means the opener is in lock mode. I never even knew what the lock button was for. I guess you learn something every day.

squidguard & google safe search

Trying to turn on Google Safe Search for all of your clients behind your Squid+squidGuard server? Well, you aren’t the first and probably won’t be the last, but it’s not that hard, once you find the right words to plug in to Google.

You need a little patch that Eric Harrison (of MESD fame) wrote. If you are already using his recent RPMs, you already have the patch. If you are compiling from source, you’ll need to grab the source RPM from his testing area and extract the squidguard-sed.patch file. Once you’ve applied that patch to the squidGuard 1.2.0 source and recompiled, you should be able to use the following code snippets in squidGuard.conf to append “safe=strict” to all google urls:
rewrite google {
s@(google.com/search.*q=.*)@1&safe=strict@i
s@(google.com/images.*q=.*)@1&safe=strict@i
s@(google.com/groups.*q=.*)@1&safe=strict@i
s@(google.com/news.*q=.*)@1&safe=strict@i
# log google
}

and in your acl section add:
default {
# for google to be in "safe mode"
rewrite google

Then, there are fewer inappropriate pictures available via google.

Thanks to Eric’s post to K12OSN and a Louisiana library page with a full squidGuard.conf linked for examples.
