Bad Caps = Bad Motherboard = OLUG Downtime

In case you did not see it on the mailing list...

Subject: [olug] Bad Caps = Bad Motherboard = OLUG Downtime

Back in the late 1990s, a formula for a new electrolyte for capacitors was stolen from a superconductor manufacturer. It was used to make capacitors, many of which wound up in many popular motherboards. The formula was not complete, and was flawed. Over time, the 'faulty' capacitors started to exhibit behavior of producing incorrectly, or erratic voltage to the CPU (as the caps are used mostly in the voltage regulator module or VRM).

The Capacitors bulge and leak electrolyte over time. One indicator of this is the toroid choke in the VRM may show scorching or heat stress.

The motherboard from the OLUG box had such capacitors, which caused the failure last Sunday night.
Pictures can be viewed at <>

So, one thing to take away from this is when you do your regular dusting and clean out of your PCs, check the caps, choke, and board surface for any irregularities. You may save your data. You do clean out your PCs, right? If not, check your fan exits and intakes, plus your CPU heatsink.

A good resource:

But, backups are always your first line of integrity.

orkut and LJ

I'm new to LJ. I've been happy with my based blog for a while. Someone invited me to orkut. Very intresting; I lost my password. Oh well. The problem with orkut is it's closed. I can't monitor things with my agregator. LJ has nice RSS and ATOM feeds. There's even FOAF support! E.G.

BTW? Can I put HTML in here?
IrishMASMS on FOAFer

I've been lazy and not dug into the documentation for LJ. So there are many questions...

e.g. RSS feed for my friends agregation page? How can I get that?

Can I customize my FOAF?

LJ is open source. How do mere mortals submit patches? Can one do an apt-get lj-server and have their own community running in no time?

Is there PGP support for signing LJ posts?

Thanks for the clues.

p.s. I still have class on Tuesday nights, so no OLUG for me this Summer. In the Fall I'll be free on Tuesday nights..... woo woo.

PHPNuke Exploit Fixed

A small exploit in PHPNuke allowed a number of email messages to be sent coming from '' or '' advertising a executable (EXE) program, freesms.exe.
The exploit in PHPNuke was found and fixed.

Network Associates tags freesms.exe as Spyware. Please delete the message. If you did click on it and install it, please make sure you use a spyware removal tool to seek out and get rid of it.
OLUG does not send .exe or links to .exe programs (especially Windows programs)

NEbraskaCERT conference 2004 Call for Papers (CFP)

Hey Everybody,

NEbraskaCERT [] has their call for papers for this year's (August 3-5, 2004) conference up at

This year the conference planners are concentrating on Practical Security, so Linux and the BSD should be a pretty hot topic. ;)

The NEbraskaCERT conference is the Midwest's Premier security conference. Honest, really :-)

Disclaimer: I am friends with the members of the NEbraskaCERT Board of directors; have attended, assisted, and presented at past NebraskaCERT conferences and will most likely be presenting this year as well.
