Lenovo with Debian

Your brand new kernel isn’t booting? Try to changes sda1 to hda1 at menu of grub. I’ve never saw this before and looked strange to me as I know that is a sata disc for sure. It works but I still trying to figure out why. Tanks a lot to João Paulo that help me to explore and fix that issue for while. Note that default kernel of debian boot with sda1 instead.

Your intel’s ethernet card isn’t working? You must go to Intel support website and take the e1000 or e1000e drivers. I’ve tested the e1000e-0.2.9.5 with kernel 2.6.22.19 for the lenovo m57 and worked pretty nice. Tanks a lot to Victor to ask for continuing steadfastly trying each of the drivers found even when they didn’t look to fit there.

I have had issues with debian too, mainly with laptops and wifi cards. But this isn’t a issue for debian, is a old issue for linux in general. That’s why I admire Ubuntu, great job about hardware support those guys are doing right now.

II Encontro de Software Livre de Pernambuco

I gave a lecture at the “II Encontro de software livre de Pernambuco“, that word by word means “Second Pernambuco’s meeting of free software”. Unfortunately I couldn’t get there before my lecture because I was working. The lecture was about Apache’s hardening. After show up how to exploit it twice (with Linux at H2HC and with Windows at uCon) I felt in a duty to find out how the best way to secure it.

uCon Security Conference I Edition at Recife

I glad to say that I was at first uCon (should I spell “micro con”?), It was just as they say in the website: “Founded in the true spirit of hacking, uCon is a totally informal conference on hacking, technology and information and telecommunication security. ” Friends “Rio de Janeiro” e “Tocatins” came from the meeting. The lectures are available for download, take a look. Great job of the The Bug! Magazine guys.

Dumb Quiz, making easier to build a quiz

That’s my new proggy, the main ideia is just makes easier to build a quiz tool. It grabs those question in a sqlite3 database embeeded as well as the asnwers. I’d so much fun doing it with python and gtk; and I’d learned a lot about software deployment making a Linux installer (RPM and DEB) as well as a Windows installer.

Note that It comes with some bugs for free, I promise I’ll fix it soon. Anyway, If you find another one, please let me know!

Sofware deploying in Unix environments

Well, software deployment is all of the activities that make a sofware system available for use. With several Linux distributions available and so many libraries versions, this can easily become a journey through madness. Be aware, work as the package maintainer isn’t that simple! But, which tools did we have to get that job done? Let start installing what we need:


aptitude install dh-make dpkg-dev

Now, you must set some required stuff and than build the package. Just that easy. But just for debian, and if you need to make package for other distribuitions? We need to proceed learning “the way of” each one? Yeah, and start to get mad again. Thinking about that I’ve been looking for some reasonable solutions. Than I find out epm and autopackage. I decide to use epm because it looks very easy to make a simple package with it. Later, I realize that it can do lot more for me…


# ls
hello  hello.list
# cat hello.list
%product Hello
%copyright 2007 by You
%vendor Vendor
%description This program prints "hello"
%version 0.1
%readme README
%license LICENSE

f 755 root sys /usr/bin/hello hello
# epm -n -f rpm hello
# epm -n -f deb hello
# ls linux-2.6-intel/
hello-0.1.deb  hello-0.1.rpm
#

Even OSX, AIX, BSD package as well as package for other computer architecture. I didn’t tried, but that’s what they say in the man page. Autopackage has some nice graphic interface, so I’ll try soon. But, at moment, epm looks great to me. Anyone knows other solutions? I also didn’t tried Alien.
