Nyxem.E

Following the news over the F-Secure site, I’ve noticed that the Nyxem.E worm has been ranked as a Level 2 Alert (meaning that is only one level below the highest alert level). This guy is spreading like mad all over the world from the USA to Australia. The web counter used by the Nyxem worm now shows over 510,000 infections and keeps rising.

The ‘Nyxem.e’ is a mass-mailing worm that also tries to spread using remote shares. It also tries to disable security-related and file sharing software as well as destroys files of certain types. It is similar to the ‘Email-Worm.Win32.VB.bi’ that was found a few days ago.

The worm’s destructive payload is activated on every third day of the month and replaces the content of user’s files with a text string “DATA Error [47 0F 94 93 F4 K5]”. Among these files are: DOC, XLS, MDB, MDE, PPT, PPS, ZIP, RAR, PDF, PSD and DMP.

You can get more info on Nyxem.E here.

Dump

Dunno wich Linux distrib is the best for you? Check the Linux Distribution Chooser.

Speaking about Linux, In my daily basis I’ve been blessed to work with Window$ at full time. Sometimes I have to retrieve and edit information from several text files and logs in order to troubleshoot problems that occurr. Not having a single Linux box in our network (except the proxy), I was in need to find utilities like tail, grep and other gnu/linux utils that worked in win32. I could install Cygwin, but I rather have something native instead of an emulated environment, so I installed UnxUtils – native Win32 ports of the GNU utilities I was looking for. It works like a charm!

Other app that I call essential is UltraEdit 32. Although it’s paid software, UltraEdit has great feautures.

Skipping to another topic: Reading.

I would like to share with you two excelent pieces of tech literature. One is a free book on Asterisk provided by OReilly , the other is a tutorial on Subnets.

Ubuntu and VNC

A few weeks ago I gave [tag]Ubuntu[/tag] another chance. The update bug was corrected and now I could enjoy my Ubuntu box without losing too much time with bugs. My ULAMP (the U is from Ubuntu) box was now ready to work, the only thing missing was the remote access. I installed [tag]SSH[/tag] and explored the [tag]Remote Desktop[/tag] feature that comes with Ubuntu. [tag]VNC[/tag] based, worked well, fast and functional, but when you logoff there’s no more Remote Desktop available. I needed VNC available from the login screen, or [tag]GDM[/tag] in Gnome/Ubuntu. So here’s a quick how to:

First, disable Desktop Sharing under System -> Preferences -> Remote Desktop.

Now install x11vnc, you can do this with [tag]apt-get[/tag] or [tag]Synaptics[/tag], this package is available in the Community Maintained (Universe) repository.

Now with [tag]x11vnc[/tag] installed, you will need to create a password file:

sudo x11vnc -storepasswd yourpasswordhere /etc/x11vnc.pass

Then configure GDM to run x11vnc when at loading time:

sudo gedit /etc/X11/gdm/Init/Default

and this line to the file:

/usr/bin/x11vnc -rfbauth /etc/x11vnc.pass -o /tmp/x11vnc.log -forever -bg -rfbport 5900

(you can change the port and other parameters)

So far so good, but if you restart your pc at this stage you’ll only be able to login, then the GDM will kill your session. To avoid this we must change another file:

sudo gedit /etc/X11/gdm/gdm.conf

now search for this line :

#KillInitClients=true

And change it to this:

KillInitClients=false

Restart you PC and now you have VNC at login time. 🙂

Welcome to the FON Revolution

If you have a wireless router at home or at work, you might consider joining the [tag]FON[/tag] movement.

What is FON?
FON is a firmware update that allows you to create a WiFi hotspot at home or at your office (as long as you have a [tag]Linksys WRT54G[/tag] or WRT54GS), allowing others to safely share your connection. The bandwidth of your equipment will be controlled in such a way that you will always maintain a reasonable capacity for your own use in your local network. That limit is independent of the number of Foneros (aka FON users) that are connected to your joining point, but this is not yet implemented in this first release. But enough of tech stuff, the cool feature of FON is that you have three kinds of users, the Linus, the Bills and the Aliens.

The Linus – Inspired in Linus Torwalds and the OSS movement, this users allow full share of their connection to the other users, including the Bills and the Aliens.

The Bills – Guess who? The outline is easy: they’ll get 50% of the money generated by Aliens using Bills access points. In 2006 a billing system will be ready to begin earning money.

The Aliens – Aliens are users of the FON network that don’t have an access point and connect through Linus or Bills. Fees are 5€ for 24 hours of connection and 40€ for one month.

This project is brand new, with lots of work to accomplish, but the idea is there. This could help you pay your Internet bills or even provide you with a better and cheaper WiFi coverage than an ISP can. I hope they add new firmwares soon and include my SMC Barricade router.

PSP Web Server

I found out that the [tag]TILT-MODE-ARMY[/tag] guys developed a [tag]web server[/tag] for the [tag]PSP[/tag] and it works!

It has some nice features like serve html, images, and files, has working headers, 404 error messages and “../” safty. They’re testing the HTTP headers at this stage of development. Quite a nice project, I wonder how long does it take until someone ports [tag]Linux[/tag] to the PSP with a full [tag]Apache[/tag] install…

Edited: Found it! 😀

Nintendo unveils Wi-Fi dongle

Nintendo just announced the Wi-Fi dongle that will allow DS (and maybe Revolution) owners to play online. It’s USB and only compatible with Windows so far.

Google WiFi Catch

This one is hillarious! CNet says in this article that the Google WiFi service has a catch:

The chief difference is speed. Google’s service would apparently top out at 300 kbps. That’s about five times the speed of telephone dial-up connections, but hardly the kind of capacity needed for many high-bandwidth services and applications. So any reports about the death of traditional telecom and cable carriers would appear greatly exaggerated.

Do they know that in Portugal we still have payed 128Kb cable connections being commercialized?
