1and1 Root Server / Plesk online resources

Wednesday, May 16th, 2007

I run a Linux server which is physically located at a 1and1 Data Centre in Germany. It runs Fedora Linux and SWsoft’s Plesk management software. I’ve had it a few years and I’m happy enough with it.

Here’s a bunch of resources I’ve found to be useful whilst doing various admin tasks on this system:

Virus: I-Worm/Bagle

Saturday, December 10th, 2005

I’ve decided to start (b)logging some of the PC problems that I fix, especially the viruses and trojans and suchlike.

A client’s WindowsXP PC was brought in to me yesterday because it was behaving oddly—amongst other things I noted that:

  • The firewall wasn’t running (neither XP’s own firewall nor ZoneAlarm)—ZoneAlarm wouldn’t run even when started manually, it seemed broken or disabled
  • The anti-virus software wasn’t running (AVG)—again, this wouldn’t run properly even when started manually
  • I was unable to bring up Task Manager using the taskbar’s right-click menu
  • Hitting ctrl-alt-del merely brought up an hourglass pointer for a brief moment
  • The system was regularly showing a dialog saying ‘Connect to av2026.comex.ru’ and requesting a user password

Using a bit of software by Sysinternals called Autoruns I stopped the system from executing files ‘C:\WINDOWS\system32\anti_troj.exe’ and ‘C:\WINDOWS\system32\antiav_exe.exe’ on boot. This then allowed me to successfully re-install the broken software (AVG and ZoneAlarm) and get the system running ok again.

After re-installing AVG and updating its definition files, I scanned the system and found ‘Virus: I-Worm/Bagle’ and successfully cleaned it up. The system seemed to have no other viruses or spyware on it.

I believe the users of this PC surf exclusively with Firefox, so my theory is that the virus came as an email attachment, or it was possibly transmitted via instant messaging.

Virus and spyware removal

Firstly: know your enemy!

Basic wash cycle to clean icky Windows:-

  1. Scan and clean with CWShredder (download + homepage)
  2. Scan, clean and immunise with Spybot-S&D (download, homepage)
  3. Scan and clean with Ad-Aware (download, homepage)
  4. Scan and clean with AVG Anti-Virus (download, homepage)
  5. Immunise with SpywareBlaster (download, homepage)

…and rinse

For grime that proves harder to shift:-

For persistent problem stains, try a different angle:-

…and repeat

Firefox, extensions and plugins

On Windows PCs, it is necessary—for a number of reasons—to replace IE. I do it with these:-

Long live the NES!

Monday, May 23rd, 2005

Some years ago I programmed a few projects for the NES (Nintendo’s 8-bit games console, famed for the original Mario Bros games)—since then, things have moved on a long way in the world of games consoles…

…which is why I was so impressed when I discovered Grand Theftendo.

Grand Theftendo is a new homebrew game for the original Nintendo Entertainment System (NES). It is a tribute to Rockstar Games’ Grand Theft Auto III running on the 8 bit, 256×240 resolution, 2 bit colour x 2 bit palette, 1.79 Mhz system, written entirely in 6502 Assembly Language!

It’s truly amazing what some people will do in their spare time—he’s even written his own 6502 assembler!

WordPress plugins of choice

Friday, April 29th, 2005

I’ve been looking at various WordPress plugins for a website I’ve been building, but also with a view to using some of them here, on my own blog. During my travels, I also discovered the tremendously useful Blogging Pro page about Wordpress plugins too.

I found two plugins that I immediately liked and installed—both here and on the other site I’m developing too.

  • Favatars which enables the use of Favicons on posted comments
  • Bad Behaviour which is designed to prevent spambots from leaving comments

…and also, for this other site I’ve been working on, I am making use of a handy plugin called Customizable Post Listings.
