compiling ruby 1.8.6-369 on Fedora 11 x86_64

Well, i like to compile my version of ruby, to use rails, and have always done that with not trouble but this time, i got an odd behaver, after make and make install, when i run my rails apps i got a rails working however every time the apps interact with the db i got xml not html on my browser as wanted,  the reason was a bug, the work arount it is to add -fno-strict-aliasing to the configure file so it changes from CFLAGS="-g -O2" to CFLAGS="-g -O2 -fno-strict-aliasing" . Then do make and make install as usual.


Enjoy

Flashplayer on x86_64

Well as you know Adobe has not release a flashplayer for 64 bits, so for now you can use the swfdec a flash player compatible that come with almost all GNU/Linux distributions, how ever if you can used or it does not work for you, then try out the Adobe Alpha release.

To download the Alpha Adobe flash player for x86_64

http://labs.adobe.com/downloads/flashplayer10.html

or

wget http://download.macromedia.com/pub/labs/flashplayer10/libflashplayer-10.0.32.18.linux-x86_64.so.tar.gz

If it does not download maybe the have a new release so check the first link.

To install it after download

tar xvz libflashplayer-10.0.32.18.linux-x86_64.so.tar.gz

After that copy the file to

/usr/lib64/mozilla/plugins

cp libflashplayer.so /usr/lib64/mozilla/plugins

Enjoy.

Avoid ssh attacks

If you ever look at you security logs and found something like

sshd[18561]: Failed password for invalid user nagios from 69.197.163.178 port 47771 ssh2


This a brute force attack to you server, yes there are some people with scripts that can be found on the net, that just try to login to you sever using a dictionary of common used users and password, so how do we avoid this, you can install denyhosts script you can download it from http://denyhosts.sourceforge.net/ or if using Fedora just do yum install denyhosts

After installation remember to set it up to start and set it to start on the next boot.

Fedora

service denyhosts start

and

chkconfig denyhosts on

How it works, it read the secure logs of your sever and watch for the host attacking your system, and the user, then it update the info on the /etc/hosts.deny file on your system so the services will not respond to this host attack again.

How ever there are more options to secure your sever using this script, for those please read


This is cool right. Enjoy.

Giving a little .. to make something big.

Been around GNU/Linux for several years, learning, showing the advantage of Free Software, and more important enjoin my self with all this free tools, I was wandering how can we contribute to this free software community, some projects has donations links, but if you want to help out and you don't have the computer skills or the money to give away, what you could do?

Well, http://fedoraproject.org is right for you, no need of advance skills, just join, and there are many projects and ways to contribute, of course if your advance coder you can join those groups too, but more important is that is open to any one. You can join to be at events, participate on improvements, help others on the use of Free Software. Every one is welcome, programmers , sysadmins, graphic designers, people persons, translators and some other projects.

So don't miss the opportunity to give something to the community that give you lot of things for free.

Recovering files from a wipe out disk.

Well as you know you better be prepare for the worst not only with backups but also with tools to recover files, with luck we ride Linux and all those tools are free, here is the ones I just recently use:


TestDisk



You can download from here http://www.cgsecurity.org/wiki/TestDisk_Download

and

Ddrescue

You can download it from here http://ftp.gnu.org/gnu/ddrescue/

A great tutorial on how to use them is found here.

http://www.linux.com/news/enterprise/storage/8257-how-to-recover-lost-files-after-you-accidentally-wipe-your-hard-drive

Hope it help you out, it did work for me.

Welcome Fedora 11.

Well this month was the official release of Fedora 11, so lets download the Live CD after download just reboot my notebook and after a while there it was Fedora 11 working no complains no rush no problems, but since it was the first test let wait a bit more.

A week later there was a request to setup Linux on a Asus Eee PC 4G, so why not use Fedora 11 on it, well it did work with no problem there, of cource this was Gnome distribution CD and this is small machine with a Celeron 512 MB of RAM and of course 4G as hard drive, so we kick out Gnome and use Xfce, just use

yum install xfce

Later we remove gnome and install some gnome applet that we needed to work on xfce one of them Network Manager applet. By doing so we won almost 800 Mbytes of free space, of course we require Open office and it eat almos 300 Mbytes, but it was working.

So installing and configuring from the Live CD work like a charm.

Now let try to upgrade my Fedora 10 notebook to Fedora 10.

To do so we run the yum upgrade and it came to this

It downloaded the release info and installer images and after a while this is a while, you can interrupt the process because it will continue later and it will restart at the point you close it. So long waiting it ask me to reboot to continue the upgrade process did some and the upgrade was completed after a couple of hours, it really works. One thing however is it take to much time on the overall process so my recommendation will be to upgrade from a distribution DVD it will save you time.

After all upgrade my screen came nice but as always some small details, the first thing to notice was that the compiz fuzion did not work any more Ati drive was not working as before, after a lot test following procedures from the Fedora forums but nothing works, why because there is no a release form my ATI Radeon Movility 9100 IGP module on the new kernel yet. So will have to wait to be able to work with desktop effects for it.

The other thing that did not work was my ruby script language, natural i have to compile it again and works.

Eclipse, Aptana has to be installed noting new there.

The omnibook driver has to be compile again so it was compile and it works no problem there and now my CPU work cooler than ever, guest a better kernel management.

The same machine and some how it feel a little faster now, maybe me, so Thanks to the people working on Fedora 11 nice going, still will wait and see how it works with compiz.

Congrats to the Fedora Team.
