Acer Problem

Although I bought a laptop with i3 processor which support hardware DEP, Acer banned it from BIOS and don’t offer me a switch to turn it on.  I asked the support but got nothing.  It really confused me why a computer producer turned a feature of Intel CPU off regardless its speed acceleration effect.  Hope Acer will offer a new BIOS which support hardware DEP.

Another problem is that the wireless card cannot be turned on by functional keys in Ubuntu, which, however, sadly lead to network inaccessibility.  I tried to search and solve the problem but it can be predicted that I would get nothing due to Acer complex power saving system, which create these complex functional keys to turn on a device.  But thanks to these power saving systems the laptop can work without AC power up to 8hrs.  Hope ubuntu will support these new hardware although there is a pathetic prediction in my mind.
Hardware DEP is now supported in the latest Acer BIOS update.

Ubuntu could drive the wired network if the driver is manually installed and configured.

New laptop on the run

My elder brother came to my home, who, to my surprise, a student with little computer knowledge.  My father suggested me that I should buy a new laptop and send the old one to my elder brother.  I took the advice.  It is barely seen that someone’s parent offer a new laptop in regular days, not your birthday or Christmas Eve.  I started asking and asking my friends. Benny likes the laptop with Intel VT technology.  But it is embedded into every Intel i-series CPU nowadays.  I need DDR3 memory which is also supported by Intel i-series.  So I finally made the choice.  I will buy a laptop with Intel i3 CPU, ATI individual graphic card and metal shell.  I also hope it is not heavy.

So there it is!  Acer 3820TG with i3.  The price is estimated around 5500RMB.  I will buy it with Intel 80G SSD.  I heard that the laptop is really quiet.  With SSD, it will be quieter.

But Acer 3820TG is not sold yet.  I have to wait for a while.

dd-wrt is suffering

I am mad at my new router.

I tried to buy a dd-wrt based router which can use my vps pptp service.  I am assumed that it can use adsl and pptp at the same time and choose the line with the route list.  However, after the pptp connection established I cannot transfer data in the pptp tunnel.  I tried to configure dd-wrt and vps but failed.  The dd-wrt is far away from linux now as a result in the weak-functioned command line.

I am now thinking about openwrt, a pure linux-based router system as a substitute.  But all the routers I like are too expensive, which are more than 400 RMB in price.  I will make the tough decision.

P.S.  I hope my new router will fully support ipv6.  Because I am used to enjoy IPV6 life now.

VPN(L2TP) over IPV6 in Linux

I own a VPS in Rapidxen who provides me native IPV6 network.  The blog is established on the vps.

For several reasons I want to establish a VPN over IPV6 in Debian.  I searched and searched, getting more and more disappointed.  Poptop (pptpd) was written in 2007 with no ipv6 support.  Neither is xl2tpd.  After sadness and useless trying, I found a patch of xl2tpd 1.2.4 (still works with 1.2.5) written by Cheng Li, a Chinese developer.

His Article is Here:http://blog.lifetoy.org/2009/09/11/vpn-over-ipv6/

The xl2tpd can be found Here and the ipv6 patch diff can be found Here.  Patch the file and install it following the README file in doc directory.  Enjoy it!

P.S.  The patched L2TP lost some config feature such as LNC Range which, however, cannot cover the light of the patch.

Thank Seer for the Unlimited IC Card.  He did such a great work…The card is so smooth so dedicate so…  It is a masterpiece.

His website is in my blogroll.  Think&Create.

It can be used for free phone calls.  There is a button on the card which can restore the money stored to 300 RMB.  However I would rather lock it in my drawer.  ChinaTel deserve its legal profit.

It is a great toy, creating joy.
