I will sign ALL my mail with GPG (The GNU Privacy Guard) so you can check if the mail was realy send by me. When it’s not signed with my GPG key, please mail me the complete header of the mail. So I am able to do something about the spamming and virus distribution. GnuPG is a complete and free replacement for PGP. Because it does not use the patented IDEA algorithm, it can be used without any restrictions. GnuPG is a RFC2440 (OpenPGP) compliant application. All common operaiting systems and mail clients are supported. When everybody uses GPG, than we could ban spam. Just delete all mail that’s not the right key! Spread the word!

Again from /.: Anyone who has ever developed a website knows that cross-browser and cross-platform compatibility is a nightmare, mainly due to Microsoft’s willful non-compliance with the CSS2 standard. As this eWeek article points out, it seems Microsoft will continue their poor support for CSS2 even in the IE 7.0 release. This may have worked when IE was the only game in town, but now that Firefox is a serious player, it won’t help them keep market share as they think it will.

On slashdot: “According to Information Week, Firefox usage is now over 6 percent,
pulling Internet Explorer usage down below 90 percent. ‘Firefox is
currently the only browser that is increasing market share on a monthly
basis, and it is growing at the direct expense of Microsoft’s Internet
Explorer’”

I’ts so easy, but it cost me 30 minutes to find it… Start Safari, open the preferences (command - ,) and go to ‘General’.
There you have the option ‘Default web browser’. Not the most logic
place to have the configuration. I would liked it better when the
option was somewhere in the system preferences panel…

Please, take a look at a Mozilla based browser like Firefox or Netscape. There are several reasons for you why. MSIE is not RFC compliant, several normal HTML, DHTML, CSS2 and JavaScript methods don’t work or does something different than it should do when MSIE is RFC compliant. An other thing is that MSIE is loaded with bug and security issues. And we’re still waiting for Microsoft to solve those. Most of the Mozilla based browsers are GPL/open source projects. That means that the geeks and hackers can view the source and find bugs and security holes faster and solve the problem with a patch, wich can be mailed back to the project developers, so they can implement it.

We webdevelopers are now building for every site two versions of the layout, one for normal browsers and one for MSIE, just because Microsoft thinks that RFC stands for ‘Read F*ck’n Complain’… So they don’t read those…

Here’s how I got an PPP connection trough my serial port. Before I can have internet on my iPAQ (with an familiar distro installed on it…) I had to compile a new kernel on my laptop with ‘PPP filtering’ enabled. You can find it under ‘Network Devices’ in ‘make menuconfig’. For IP portforwarding you’ll have to have some more stuff in your kernel you can find here. How to build a custom Debian kernel package is here. Also installed ‘ppp’ on my laptop with:

apt-get install ppp

Before we go on, I’ve got an internal network with a NetGear router, it’s IP number is 192.168.1.1 and it’s the internal gateway and DNS server of my laptop. When you don’t have the same setup, change the 192.168.1.1 into the IP number from the gateway (or DNS) from your access-provider.

Then I made a file ‘/etc/ppp/peers/ipaq‘ on my laptop, with this content:

-detach
noauth
nocrtscts
lock
local
ms-dns 192.168.1.1
user ppp
connect '/usr/sbin/chat -v -t3 ogin--ogin: ppp'
/dev/ttyS0
115200
192.168.0.1:192.168.0.2

Then edit the ‘/etc/modules.conf‘ on the iPAQ and add these lines to it:

alias /dev/ppp          ppp_generic
alias char-major-108    ppp_generic
alias tty-ldisc-3       ppp_async
alias tty-ldisc-14      ppp_synctty

Then add to ‘/etc/modules‘

ppp_async

Now reboot your iPAQ with the command ‘reboot’. Then kill your minicom, if it’s on… and then open the ppp connection to the iPAQ from your PC, on Debian you do that with

pon ipaq

When it works you’ll see this

Serial connection established.
Using interface ppp0
Connect: ppp0 <--> /dev/ttyS0
Cannot determine ethernet address for proxy ARP
local  IP address 192.168.0.1
remote IP address 192.168.0.2

Now you can ssh to the iPAQ…

ssh root@192.168.0.2

With me the login takes a second or 10… So be patient, it’s a serial connection ;)

Now you want internet on your iPAQ trough your serial PPP connection. So when you’ve compiled IP portforwarding (see my howto) in your kernel, you do the following. Make a file ‘ipmasq.sh’ with the following contents:

#!/bin/sh
#Assuming external internet card is eth0, and IP is 192.168.1.2
# modprobe ipt_MASQUERADE;
#Uncomment line above when you didn't compile it into the kernel
iptables -F; iptables -t nat -F; iptables -t mangle -F;
iptables -t nat -A POSTROUTING -o eth0 -j SNAT --to 192.168.1.2;
echo 1 > /proc/sys/net/ipv4/ip_forward;

Make the file executeable by doing:

chmod +x ipmasq.sh

Now start it as root

./ipmasq.sh

Okay, now you should be able to ping your gateway, in my case 192.168.1.1. When you’ve got a ping the ipmasq works. Now try to ping www.google.com, that should work now to!
Now you can upgrade your distro with

/root/postinst
ipkg update
ipkg upgrade
ipkg install less
ipkg list | less
ipkg install madplay

Have fun ;)

There are some fake e-mails send with some random @daantje.nl addresses. When the email doesn’t have a known signature of mine, and it has a small attachment, just delete the message and DON’T open the attachment! Please beware, it’s some kind of virus and it uses random known from and to addresses from other infected michines. It’s not me that’s infected, but some other poor sole(s) I comunicated with.Neat way to check if you are sending mail without your knowledge, apt-get install ettercap or some other network scanner…

UPDATED 13 aug 2003! Removal tool is available for ‘Blaster’ worm! My brother and some friends just called me today, they are running Windows XP and there computer is shutting down out of the blue… They get a count down box and the computer is shutting down when it’s to 0. Now I did some research… It’s a worm named ‘blaster’. You should activate or install a firewall! Look here for more info and the worm removal tools: http://www.microsoft.com/security/incident/blast.aspI think those worms and virruses are a great thing. Why? Because I think it’s the only way to force you to think about your security and the developers about there source code, architecture and fast bug fixes! Don’t be a sheep! Think it trough when your installing or downloading something! Is it tested right? What security issues can be found at google? What is the reputation of the software? Did YOU read the manual??

I rest my case ;-)
