Google Wave Prototype server

Although I played with the Google Wave Prototype server quite some time ago, I decided to stop running it since I won’t be playing with it much, but as I was upgrading ejabberd today, I decided to start up the Wave server again.

If anyone else has setup the reference server and wants to test Federation with me, please send me a wave! :)

My wave server is : wave.hamzahkhan.com, and I am logged in as mhamzahkhan@wave.hamzahkhan.com.

Help BakaBT

Hello BakaBT community and people of the Internet,

We need your help! Please spread this message everywhere on the Internet.
If you have a blog, twitter or myspace or know someone with a blog, twitter or myspace copy this message verbatim!

I am writing this message right now as my community website is unreachable due to a continued DoS attack.
A DoS attack is a Denial-of-Service attack that drowns all normal traffic going to the server by sending a tremendous amount of (fake) traffic.
It is the bane of any website owner as there is very little you can do against it, other than hope the attack will stop or invest in special expensive DoS protection hardware.

The demand of the attacker is that we remove information we posted about his person a while ago on our blog after he did an earlier (simpler) attack.
We managed to dig up all sorts of interesting information thanks to another site (www.0xyg3n.com) which had also been attacked by the same ‘hacker’.

Our site has been down for 24 hours, after which the ‘hacker’ promised to stop the attack and give us 1 week to remove the message.
The attack never stopped, normal traffic was able to siphon through so the server seemed reachable. But this means he obviously can not, or will not, negotiate with us.

We have thought a while about what to do, and we have reached some conclusions:
Apparently there is something valuable in the message that we posted as the ‘hacker’ is spending a fair dime attacking our server (DoS attacks ‘sell’ for about $60 for 24 hours).
There is nothing that we can do to make him stop this attack. Yes, we could give in to his demand, but why would he stop the attack then? He sure isn’t stopping now. And then what is next? last time he asked for my resignation.

So, we have decided to fight fire with fire. Fight a distributed attack with distribution, and for this we need your help!
If you have a blog, twitter or myspace, or know someone with a blog, twitter or myspace, copy this message verbatim!
If this message is copied many times to many different sites all across the Internet no one will be able to erase it from the Internet.
What happens to our website and 6 year old community? I don’t know. It would be a shame to loose it over something so trivial.

Below is a summary of the information we found about him (please copy this as well as that is the whole idea of this message!):


I also have his home IP from the comments 77.162.16.18 [...] Anyway since then I have noticed I’ve been getting hits for people doing a search for his site 0xyG3N.info (which I’ll point out has been offline for some time) I would also just like to say that his site has nothing to do with me everything I do online is only via 0xyg3n.com [...] He also uses the username roffamaffia which I suggested he should go back to using. He also uses kyuubinyuu@hotmail.com as an alternate email to the msn one.

I also know his name which is mesut baysan he’s 15 and lives in Dongen Noord-Brabant Netherland oppps. I also have a home address but I’m not going to post that up as I’m not sure if its totally correct or not. I also have some other details that I’ll save for a later post if needed.

Cisco CCNP Lab Kit

Cisco CCNA Lab Kit

As I have pretty much completed my studies for CCNA, I decided I would build up my lab so I could “practice” for CCNP. A lot of people recommend using a simulator/emulator such as dynamips, but I don’t think that works out to be just as good as using real hardware but that’s a different matter. :)

I had originally bought my CCNA Lab Kit from the nice people at ITelligentsia so I decided I would buy the rest of my equipment from them as well.

My current lab consists of the following:

  • Cisco 1800 Series : 1x Cisco 1841 (I bought this separately from someone else)
  • Cisco 2600 Series: 1x Cisco 2610, 2x Cisco 2511XM, 1x Cisck 2621XM
  • Cisco 2500 Series: 2x Cisco 2501, 1x Cisck 2509
  • Cisco 1700 Series: 1x Cisco 1721 (I bought this separately from someone else)
  • Cisco Catalyst 3550 Series: 2x WS-C3550-24 SMI
  • Cisco Catalyst 2950 Series: 3x WS-C2950-12
  • Catalyst 2900 Series XL: 2x Cisco 2924XL
  • Cisco 2000 Series Wireless LAN Controller: AIR-WLC2006-K9
  • Cisco Aironet 1200 Series: Cisco Aironet 1231 (AIR-LAP1231G-E-K9)
  • 3x Cisco Unified IP Phone 7912G

Hopefully this should be enough to allow me to get going, although I REALLY need a new rack. My 24U rack is already full, so my UPS (4U), Server (4U) and new lab equipment are sitting on the floor, and being very difficult to get access to.

Hopefully I will be able to get two (better be prepared for CCIE Equipment too!) from work in March as we will be moving offices, and from what I can tell, they will be getting new server racks. :)

I also bought a UPS a few weeks ago, but I’ve been having some trouble with it. The UPS is a PowerWare 5119 RM 3000VA UPS. I have connected a few of my routers to it, and left it charging for over 24 hours, but when I kill the power the UPS goes into a strange state in which it seems to keep switching on and off and lighting up random lights on the front. From Googling a bit, I found that I might need to change some settings using the management serial port. Unfortunately, the UPS does not use a “standard” serial pin out, so I will have to build a cable when I have a chance to. Hopefully I will be able to sort the issue, otherwise I will have to send it back to the place I bought it from for repair. :(
