In addition to Asterisk, Mark was also one of the original coders of GAIM. He's from around my neck of the woods, so I've been lucky enough to speak with him (briefly) at a few cons. He's a really cool guy.
No not exactly. The University of Alabama is several counties North of the blue line...and with the exception of the professors it leans republican. Yes Montgomery is in the middle and Auburn is in the east, but again there are caveats to that. First Montgomery is not exactly what I'd call a prosperous city. It is the capital of the state but it is poverty-striken. Also, Auburn...while a good school with a good Engineering dept...it's still mostly an agricultural school.
While most of the blue areas are located in large metro areas, this is not always the case. That blue streak that runs east-west across Alabama is an area known as the "Black Belt" and is one of the poorest most underdeveloped parts of the state.
Asside from changing the password (or WEP key) constantly and having the professor tell the students what it is each class, you could shield the classroom so that the signal doesn't travel outside of it. This of course assumes that the access point is in the classroom and that the room is small enough to electromagnetically shield economically. Depending on the size of the room (big lecture halls) you might be able to just turn the signal strength of the AP down low enough so that it can't be reached outside of the room.
I imagine this would be much like the "crime report" section of American papers, but would list the person's name also. I guess it's meant to shame the person.
Are you really looking at setting up a community with a user database and a full-fledged comment system, or do you just want a personal website? If you just need something to make posting to your personal site easy and searchable, you should try Personal Weblog. The homepage is at http://www.kyne.com.au/~mark/software/weblog.php It supports RSS feeds, CSS, Mysql, and Postgresql. It is the easiesy way to put blog support into an already designed webpage IMHO.
I attend the University of Alabama in Tuscaloosa. It's funny that two campuses in the same University system would take different approaches to security.
Here at UA, everyone gets a real IP address: there is no NAT. There is a "traffic shaper" on resnet which limits upload speeds and blocks incoming connections on some of the lower service ports (80, 25, etc). Central computing blocks incoming connections to port 25 except for mailservers, but that is just to prevent open-relay spam. Other than that, there is no firewall.
Each college has it's own labs. The arts and sciences labs are locked down one way, the engineering another way, c&ba another way, etc. In most cases students can't copy files to the hard drive or fiddle with the control panel, but other than that there is no real "lock down".
I work for one of the colleges on campus and we have been trying to get a firewall for our labs and faculty for years, but central computing won't allow it. They won't the network to be open, not for academics sake, but so that they can keep tabs on what everyone is doing. They think that if we put up a firewall it will keep THEM out too.
I'm running sendmail with Mimedefang calling spamassassin and uvscan. This server sits in front of 4 exchange servers and handles incoming and outgoing mail for about 10,000 users. Spamassassin was marking the messages as spam right off the bat. An updated dat file for uvscan came out around 11PM Monday and my cronjob auto-updated it. From around 11PM Monday to 7AM Tuesday we were averaging around 200 per hour. At about 8AM until now that has jumped to about 500 per hour. For a point of reference, we average about 400 rejected spam messages and 200 tagged-and-sent spam messages per hour. So far there has been no effect on the load of the machine at all. The big virus in September (what was the name of it again...sobig?...) had a much greater effect (although the load on the linux box was still pretty low).
We had a drive in a RAID5 container go bad at work a few years back. This was a raid controlled by an old Mylex DAC960. A guy I worked with went to replace the drive. He powered the machine down, took out the bad drive, put in a new spare, and powered the machine back up. In the controller setup he was presented with two options: rebuild and make online. Well he chose "make online" instead of rebuild. This caused the controller to render the raid volume completely useless. He chose poorly.
You could write a cgi-program that calls Etherwake. Or you could be even more savvy and write a cgi or php program that just sends out the wake-on-lan "magic packet" by itself. It's just an ethernet packet. Bear in mind thought that the webserver is going to need to be on the same network as the machine that you are trying to wake up or it won't work.
Uhm, that's not how it works. Your University shelled out a ton of cash for students to be able to have those free copies of Windows.
And if you read the article you would have seen that Redhat is also offering Universities a site licence deal: $2,500 for unlimited copies of WS. That's a hell of a lot cheaper than what your University paid for an MS site license.
I think this is leading to something big. Something big and blue...
-Now- IBM invests $50mil in Novel. Novel (Ximian Gnome) buys SUSE (KDE).
-2 years from now- Novel unifies Gnome and KDE into one monster windows-eating desktop machine. Meanwhile Redhat and Novel(SUSE) continue to make gains in the server market.
-5 years from now- IBM buys Redhat and Novell. Unifies them both into the ultimate Linux Distribution. MS finally releases Longhorn but is blown out of the water by IBM's Redhat/SUSE linux distro. IBM finally get's their revenge on Microsoft.
Agreed, but I would really like get the first warning after a very short interval. I don't run my own SMTP daemon -- is it possible to send a first warning after 30 minutes and not every thirty minutes?
I don't think this is something you can do with sendmail. I think you can only specify an interval, not whether you want just one warning or a warning every interval. Anybody have any clues?
I suppose an alternative would be to warn after 30 mins and then discard the message if not delivered after 59 mins. This would allow people to only get one message, but you would have to process your queue very frequently (like every 5 mins or so) if you wanted to actually have a half-hearted attempt to deliver the message.
I have my queuereturn set to 2 days and my queuewarn set to 12 hours.
I don't have the queuewarn set to something like 30 mins because I have a feeling my users would complain to me if they got warning messages every 30 mins.
I ran a USB mouse from his workstation, under the cube wall to under my desk. Every once and a while I would kick the mouse with my foot and would hear him scream "What the hell?!". What was great was to do it when he was talking to someone and hear him scream "did you see it move?! did you see it? I didn't touch it and it moved I swear!".
What happens when there is an exploit in something like the TCP stack that is used by the kernel that the bootable cd is using? Then your machine is exploitable everytime you want to play your game. The game company isn't going to want to press another edition that fixes the exploit and replace the old copies on the shelf with it so that your machine will be safe.

Well that doesn't do us much good since the google cache doesn't include the pics...
The car is kind of goofy looking...
Whatever man, I think it looks awesome. Fark hit the nail right on the head when they described it as the batmobile in their headline.

Does anyone know if this only affects SUN-branded java? IIRC, the version of java (and plugin) that ship with RedHat Enterprise is IBM-branded.
Just curious...

Why? Because Apple refuses to put an FM tuner in any of their music players...or because they refuse to ship an inline remote anymore...

The ISO is only 46MB, which means you could put this thing on a business-card CD and tote it around in your wallet. How cool is that!

They currently have 10 Red Hat servers (they are open to distribution change) that have not been actively maintained for a few months.
Can you give us the IP addresses of these machines?
Seriously though, make sure those babies are patched and secure before you worry about learning anything.
If you drive a diesel (beit a pickup or an auto) you are allowed to pump your own fuel. I guess technically it's not gas though...

I'd just like to point out that I predicted an IBM buyout of Novell/SUSE before anyone else did ;)
I think this is leading to something big. Something big and blue...
-Now-
IBM invests $50mil in Novel.
Novel (Ximian Gnome) buys SUSE (KDE).

Unifies them both into the ultimate Linux Distribution.
MS finally releases Longhorn but is blown out of the water by IBM's Redhat/SUSE linux distro.
