Try Gilat. Depending on where exactly these remote sites are, they may be able to use these guys. Gilat also just signed a deal with Dish Network awhile back to provide 2-way satellite internet for users, no dialing up with a phone line anymore.
Dish Network had a demo at the MN state fair this year. The guy was really hyping it up. I played around with it a little, I couldn't get anymore than what a 33.6 modem would get, and latency to the gateway was ~750ms. I don't know if the gateway was the satellite, or a ground station. The satellite is 22,000 miles above the equator, hence the high latency.
If a Gilat dish would work for you, you could just do a tunnel with ipsec over it to connect it to the other offices.
Yeah, but the throughput and seek times were slower on the ramdisk than on regular disk. If throughput and seeks were higher, I could see why the cpu would be higher.
This is something different. It has nothing to do with a Ramdisk. Apparently Redhat's next release is going to include this thing. It can run in the kernel, but can also run separate from it.
It was posted awhile back, I couldn't find the link though.
Just because it's in Ram doesn't mean it's faster. You're still putting a filesystem on it and you have the overhead of the filesystem, it still uses flock(), and if your box dies you lose your data on it.
I looked into this awhile back. Go ahead and make a 200MB ramdisk on a machine with lots of ram. Make an ext2 fs on it and run some benchmarks on it. Then run the benchmarks on your disk. In most tests, my crappy IDE disk outperformed the ramdisk (1GB of mem in the box, so I wasn't swapping). CPU was much higher when testing the ramdisk, at 100%. I think it's because there was no DMA controller being used when using the ramdisk.
Yes, it would have, but I don't think they figured out I had ipchains rules. Looks like the ADMROCKS exploit lets you execute commands remotely as the user named is running as, but doesn't explicitly give you a root shell. I guess they could've just done a "rm -rf/" and hosed the machine, but I didn't really care, I had backups of all the important stuff.
Moral of the story, never run named as root under any circumstances, and always run it chrooted. In fact, never run anything as root if possible, and chroot what you can. An attacker can break out of a chroot jail, but it'll stop most script kiddies from doing much damage.
I was thinking of switching to djbdns for my nameserver on my DSL, but now that bind 9 is out, I wouldn't mind experimenting with the 6-bone a little bit, and djbdns doesn't do IPV6 as far as I know.
I remember this. It was ADMROCKS though, not AMDROCKS. I got hit by this. I had so many friggin ipchains rules on my nameserver that they couldn't do a damn thing with it. They appended telnet onto the end of inetd.conf and added a couple of user accounts. But never added an ipchains rule to allow all, so they couldn't telnet in to do anything.
I sat and watched them play around with it for about 2 hours before I blocked their IP, upgraded bind, and chrooted it. Gotta love snort.
Why would he tell them he did it? I'm not a criminal, but if I were, I sure as hell wouldn't go telling people that I did it. Especially the people I commited the crime against. He deserves to beaten for just his shear stupidity.
Sue. Sue their pants off. I use my card for work and my company can call me in the middle of the night and say, "you're on a plane at 10 for New York", and I'd have to go. My bank takes 2 weeks to replace a card, I had to do it a couple of months ago. During that time, it was impossible for me to travel.
A large financial site should take every possible precaution to prevent such things. It's essentially the same as leaving a stack of credit receipts on the store counter and walking away for 30 minutes.
I can guarantee you that when my online store is up (if I ever get time to finish it), there will be absolutely no storing of card info at all. Even if the card numbers are "sneaker net'd" over to a box with no NIC or modem in it. None. If I stored card numbers and someone broke in and got them, I would fully expect my customers to hold me liable.
Actually, I was thinking more like a private network that standard protocols work on, like http, ftp, ssh, etc. I don't think hotline is encrypted either is it?
Maybe once I get my DSL installed at my new apt, I'll start poking around with this. Anything I do, I'll post on http://www.signal15.com once it's back up.
I've always wondered how feasable it would be to set up a LARGE virtual network on top of the internet. The problem would be making sure that only trusted people get onto it.
Once you have this large network, you'd be free to do whatever you wanted on it, with not much worry of law enforcement, government, or clueless people interfering with your work.
Think about it, multiple IPSec tunnels to different nodes, and gated running with OSPF or BGP4 for dynamic routing updates in case someone elses node goes down.
Of course, you'd be reliant upon owners of the other nodes keeping them secure. Maybe a linux distribution that is specifically for making a node for the network would be better rather than trusting each user to set up and secure his own box. Run the installer, give it an IP, and tell it where a couple of nodes are. Make extensive use of encryption, especially for authentication, an you're all set.
For an nice layer of anonymity, it would be nice if freedom.net allowed IPSec tunnels through their network. Although ssh works, and you can always do ppp over ssh.
There's endless possibilities to how this could work, but it would certainly be an interesting project.
I found college fun, and it was a good way for me to hook up with some job experience in computers. But other than that, it was a waste of money. I didn't graduate because I got hired before I graduated and the company that hired me didn't care. Most IT places are looking for people with experience and brains anyway. Just because you have a college degree or any other kind of certification doesn't mean you know jack shit.
My brother just took one of those 6 month crash course Oracle/VB/Powerbuilder thing that says they have a 99% placement rate. He doesn't have any real job experience in IT, and no one will hire him because of that. Crash course certs are usually useless anyway, but it does go to show that most place want experience above anything else.
Hi, we're Sega. We don't know who you really are, but if you stop pirating our games we'll give you stock options. Then when you go to collect on them we'll find out who you really are. Then, we'll duct tape your wrists to your ankles and our lawyers will take turns until you can no longer walk.
guy one: "how are we gonna get funding and access to test and design facilities?"
guy two: "Let's make our technology look really sweet and we'll license it out to some major corporations, including one or two with chip design and testing facilities. Then, after we get what we need out of them, we'll just try to buy back our rights with some stock from when we IPO and a relatively small cash payment compared to what we'll make on the IPO."
guy one: "Sweet, let's get drunk."
Transmeta's has had everything look very well thought out up until now, I fail to see how they would have just now "changed their minds". They're doing alot of very risky things, but it seems like it's been well planned since day one.
You can still go under "view" -> "source" and see the source to the page.
The only way to get around this is to use javascript to bring your site up in a window without the menu buttons. Even so, if someone's determined, they'll just use "lynx -dump" or wget to grab your source. The only way to really protect it is to use flash or shockwave, and that's just plain annoying.
Maybe it's time to just start whacking all of this stuff up on freenet or some other "un-censorable" information sharing technology. Paying someone an assload of money to use their book as a reference for a limited amount of time is complete BS.
Maybe someone should start up an auction site out of the country that caters to the US and sells copyrighted material (not copies, originals) since Ebay and many of the other large auction sites will not even allow auctions for software, certain books, or CD's.
Didn't NeXT make something a long time ago called the N-Cube or something similar?
I don't know if it's still there, but if you go into the CSci building at the U of MN, they have this thing thats about 2' x 2' square, and 5 feet tall. The top has a pyramid on it and it says N-cube. The doors on the sides are tinted glass and it has hundreds of blinking lights inside and it looks like it's doing many very important calculations at a blistering rate of speed. However, I asked one of the sys admins what it was, and he opened up one of the tinted doors, and what I saw completely amazed me. It was powered by cheap 2-dollar blinking christmas lights. The machine itself wasn't even plugged in, they just looped a couple of strings of blinking lights around inside of it. Apparently the machine is too slow to do anything useful but look good.
Is there wireless support yet (cdpd, richochet, omnisky, etc.)? I wanna be able to sit in the park, read slashdot, and run nmap on entire networks from the comfort of the soft grass.
If you've never had your palm or visor lock up, you're either the only one, or you haven't had it very long. I have a visor and know several people with Palm's, and we've all had our's lock up. Sometimes requiring a soft reset, where you keep all of your data... and sometimes a hard reset where you lose all of your data. Usually the lockups result from some 3rd party program that was loaded.
I need to figure out how to get them to quit clawing the sofa all to hell too. Too bad Aibo isn't faster and smarter.
Someone told me to make a great big sheet of duct tape and lay it sticky side up on the counter top, but I don't think I wanna pull that off an irate cat along with all of his fur. I gave one of 'em a bath last night and he almost killed me.
Anyone have any ideas on how I can build a little mindstorms thing that will sit on my kitchen counter and spray my cats with water when they jump up there? I know when I'm at work they jump up on the counter and dance around until they get tired and then fall asleep next to the coffee maker until they hear my car pull up, then they run to the other room and pretend they've been there all day.
Motion sensing might not work very well because people who walk by would get sprayed. Image recognition would be best, but I'm not quite sure how to go about it.

One good thing comes of using windows... If their GPS box dies, they can replace it with a Word document with a tracking pixel.

Aterm. Aterm is a highly modified rxvt that has all the goodies of Eterm. Eterm is a memory piggy. Aterm uses about the same as a regular xterm.

Anyone bother to check to see if the Word doc contained a tracking pixel???
