Infiltrator

It has happened to me before, so basically what will happen is once you Firefox has been updated to 4. Next time Firefox is started, it will advise you what extensions could not be loaded due to incompatibility. And this is what I do, in order to keep using the extensions. 1) Don't upgrade the current version of Firefox and still use it with the extensions. 2) Download the latest version of Firefox, from the portable apps website and use it. You can still use both versions of Firefox, but only one instance at the time.

I attempted decoding the string using base64 decoder, but it said something about not a valid base64 string. You could be right, it could have been encoded into base64 before being encoded into something else. The only way to verify this assumption is looking at the source code, that encoded the string.

Very interesting theory, wanna see who's gonna be the winner in the end.

I can tell you that the string was not encoded using base64 It must have be encoded in a different format, may be in ASCII code. Not sure, it could've been encoded by anything. From which website did you get those strings from?

I am going to install Proxmox and will find out for you how to change the upload size limit.

I've ran into that problem as well, it never worked for me. I searched other forums for help and it was suggested that my target machine was fully patched or not vulnerable at all. What version of XP/Vista are you using?

I've never heard of that virus either, but if you can get hold of the infected file try uploading it to http://www.virustotal.com/ For analysis, in addition you can use this website http://virusradar.com/ to search for the virus and get a technical report of what it does.

How something so simple can, really screw up your system security. Whenever I write apps in PHP, I always sanitize all the inputs, ensuring all the inputs are valid. I think its something that web application developers should practice more often, to ensure a safer web.

OK, what type of applications do you intend to build?

Interesting, I tried on another forum i am registered with and didn't quite get the same results. I would guess they have already patched up the vulnerability.

Have you tried this yourself?

When working with electricity you always have to be cautious, anything you do wrong can kill you. So its always good to take pre-cautions, don't rush and think about what you are doing and have fun.

Just adding to what Digip said about arp-poisoning. These tools can help, alert and prevent arp-poisoning. ArpWatch only alerts you of potential arp-poisoning. ArpON alerts and block the attack.

Now with my 2 or 3 years old PC, I tend to leave it on stand by, rather than leaving it switched on over night consuming electricity. The only time I leave it on, is for downloading TV shows.

I tried it once and it tasted awful. I don't know how people can take it as it is.

How To Geek wrote an article on Radiation Exposure, quite interesting read. http://www.howtogeek.com/news/understand-radiation-exposure-infographic/4016/

Ohhh, now I got what you mean! Good for you, I wish I could too

Source: http://www.karosium.com/2011/03/home-server-power-supply.html DIY Power Supply for Home Server I'm replacing my old power-hog home server with a new one based on the Intel D945GSEJT mainboard. This board is essentially a netbook platform that's been "desktopified". Among it's weirder points are that it uses the Mobile 945GSE chipset, SODIMM ram, 44PIN IDE, and that it runs off a single 12V supply. The reason I chose this board is that it consumes 13W in idle and 18W under full CPU and GPU load which is pretty much the lowest power consumption one can get with an Atom system (excluding some server-specific boards that were beyond my budget). Not wanting to use an ATX PSU I've decided to build a completely new power supply for the board. Not having to bother with all the voltages needed for ATX makes this a lot easier. I've decided to make a high-amp 12V supply, and a 5V supply capable of driving two HDDs. I bought (actually it was a swap for some things I no longer had use for) a 100VA toroidal-core transformer to start with. This type of transformer is widely used by audio amp builders for example as they're more efficient and take up less space than plate transformers. After that we have the usual bridge rectifier and smoothing capacitor combo. For the latter I'm using a single 10000uF/63V electrolytic cap, a RIFA PEH169 rated for 78000 operating hours(cca. 9 years) @85C. Since we're nowhere near the rated voltage or the temperature given for the operating hours It should probably be safe to say that this cap will outlast everything else inside the case. After rectification I get around 18Vs from this setup. For the DC regulation I decided to go with TI's power modules. The 6Amp PTN78020 for the 12v supply, and the 1.5Amp PTN78000 for the 5V one. The 5v supply is because I don't want to run more than 1 HDD off the board's internal dc-dc power supply so I'm running a couple of molex connectors from inside the PSU for 2 more. These power modules are pretty impressive. Essentially they're complete switching regulators on a piece of PCB. You just need to add some input and output capacitors (and optional ripple filtering) and you're done. They can reach up to 96% efficiency and come in 1.5/3/6 amp versions with various protections against frying themselves and whatever it is they are powering. I went with the recommended implementation from the datasheet just adding the optional output ripple filter. Low ESR electrolytics and 1uF SMD ceramics. The thing to the left of the caps is a double ferrite bead. The 1.5Amp module doesn't have the optional filter. At this point I was considering what to use for the output cap. That's why there isn't one in this picture. Ended up using the same as in the 6Amp module (470uF Low-ESR Samxon) This is how the completed PSU looks like: I've just replaced my old server with the new one powered by this PSU.

I haven't tried this before, but I think it may be possible through the use of virtual directories in Apache. Edit: Or a DNS server.

That really sucks, and that is a shame on them.

Thanks dude, will give it a shot.

From a security point of view, I think you got most covered yourself. Software: Firewall - I would use Comodo, it has quite some nice security features up its sleeve, like host intrusion prevention. Anti-Virus - I don't mind Microsoft Security Essentials, but I never had any good experience with it, so I would recommend Avast 6.0 instead it does really well in securing the system. Miscellaneous: 1) Keeping the system up to date is very important, it not only reduces your chances of being exploited but Metasploit but it make your system more secure. 2) As you suggested, I would definitely uninstall any third party software, like Adobe, Quicktime or Java too. Making your computer less vulnerable is the key to keeping it secure. 3) This one is a very important one, strong, complex and long passwords is a must. It not only dramatically increases the brute force time frame but it will slow down the attacker, for this they will need massive amount of computational power to crack the password. 4) I would also disable USB ports on the computer, just in case they try to do USB attacks on you. Offense: 1) Metasploit is very good for pen-testing, for finding weak security spots on the system. But you have to be aware that most attacks nowadays happens on the client side through browser attacks. For example, if an attacker wants to gain control of your PC, he/she could use social engineering to convince you to open an attachment, giving them access to your computer through a reverse shell. 2) Or an attacker could send you a link to a crafted website that has some kind of malware designed to penetrate into your computer, thus giving them control of your computer. So with that in mind, don't go clicking on links that you are not certain they are safe. If you have to use a Virtual machine, that way the infection is only contained to the VM itself. Software: Nmap Nessus Metasploit These are great tools, however you could use Cain and Abel to do a bit of sniffing on the network to see if you can capture passwords.

Unfortunately, Nvidia does not have plans to support Optimus on Linux system. Perhaps in the future I'd say. http://www.nvnews.net/vbulletin/showthread.php?p=2183477#post2183477 http://forum.notebookreview.com/linux-compatibility-software/473915-no-support-nvidia-optimus-linux.html

For now I would stick with IPv4, it still offers good security for your home computers, because the NAT built in features in the firewall. I know some people are already taking the plunge into the IPv6 world, but I don't see the need to rush out and implement IPv6 for now. I would wait until all these security issues have been addressed.
