What's New in BitComet 0.61
Many BitTorrent leechers like to use BitComet because of its performance comparing to memory footprint comparing to the most famous Azureus. Azureus may be the best but it is so huge. Machines older than 1 year are not recommended to run Azureus. Furthermore, your physical memory should be at least 512 MB.
However, BitComet is banned by most of private trackers. Private trackers mean to tracker keeping track of upload and download ratio for controlling leechers. Most of them add a key to metadata so that the session could be identified as a known user. However, this mechanism is useless in front of BitComet. BitComet has their own tracker so every instances of BitComet can share pool of peers together in centralized fashion. In addition, DHT network makes this tracker to span on all peers.

What to do if your computer is hacked
Today, I have just found that one of my machine has been hacked by unknown intruder. That machine is Rocks 4.1 which is an extension of CentOS 4.2 Final. Actually, I didn"t know that it was hacked before notification from NOC. My NOC received the notification from eBay. I am one of the team to investigate this problem. Below steps are what I do.
- My colleage found that there were many process named `(swapd)`. Unfortunately, the executable was removed.
- So I looked for login record using `last`. I found one weird login namely `ftpd`.
- As I remember, I have never started any ftp service on this machine! There was something wrong with user ftpd.
- So I opened /etc/passwd and /etc/shadow to find more information about user ftpd.
- Sadly, it was on the last line and enabled logging in. This must be some kind of backdoor.
- Then I tried to find out more using netstat and ps. Nothing found! This is so strange because I couldn’t use netstat -p. It seemed netstat were replaced by rootkits.
- So I didn’t believe anything I saw and started to verify common executable like netstat and ps using rpm -V.
- Well, they were replaced by rootkits like I thought. So I downloaded all necessary executables from another machine.
- Next step was to see what command user ftpd had done in .bash_history. Nothing.
- So I backed to verify history of user root. Bingo! The intruder forgot to remove history of root.
- In the history, I found commands for preparing eBay phishing in 4 steps!
- Create .eBay directory in /var/www/html
- Download http://www.pishat.com/ebay.tgz and extract it in .eBay
- Download http://www.pishat.com/neptune.tar and extract it somewhere
- Run install script
Once I had the ebay.tgz, I looked into the code and found that it was a kind of phishing against eBay! At the last step, the victim’s credit card information will be sent to . Are you hacked? Don’t worry too much. If you are already hacked, you are hacked. You can change nothing. For me, this machine is just for installation testing so I will just simply reinstall it again and again.

Google of in this early morning (Bangkok time). However, Google Updater bundled with that I installed 4 days ago doesn"t notify me about software update.
Probably Google Earth for PC has been released unofficially prior to Google Pack... Otherwise, this is a bug.
