bash completion not working on Fedora

2010-06-06 1 min read Bash Fedora Linux

I had bash completion installed and after that I had made huge changes to my bashrc and also installed bashstyle. After this the bash-completion stopped working.

I had to spend a lot of time to figure out that the easiest solution was to source the bash-completion again in the end. 🙂

. /etc/bash_completion

colors in bash -- script to display all the possible colors.

2010-06-06 3 min read Bash Fedora Linux

If you wanted to have colors in the bash output (including the colors in PS1-4), don’t you keep wondering how the color code would look on the terminal. So, I wrote this small script to show the complete color codes. This is how the output would look:

$\"Bash$

And here is the script:

Security — Installing and monitoring snort logs.

2010-06-04 2 min read Fedora Linux

Snort is a very good security tool to install if you are concerned about the security of your system. I find it really useful but the problem is I keep forgetting to monitor the logs so what did I do, I installed snort and configured cron to send to logs everyday, here’s how.

On fedora, snort is available in the repository but the rules are not. So to install snort just type in the following in a terminal:

redet – build regular expression (regex) for any program.

2010-06-04 1 min read Fedora

Even if someone is a regex guru there are times that people get confused with some regular expression and want to either test it out or want to some help. Behold, redet is here. Lets start with installing redet:

sudo yum install redet

Once you are done with installation, just run it with redet. First you need to load the sample data, select your program and then enter the regex to test it out. Here are some screenshots to get you started.

On my personal <a class="zem_slink freebase/en/client" title="Client (computing)" rel="wikipedia" href="http://en.wikipedia.org/wiki/Client_%28computing%29">desktop at home, I like to see the <a class="zem_slink freebase/en/statistics" title="Statistics" rel="wikipedia" href="http://en.wikipedia.org/wiki/Statistics">statistics at least once a day, for what was installed, what was run with <a class="zem_slink freebase/en/sudo" title="Sudo" rel="homepage" href="http://www.sudo.ws/">sudo and other such details like <a class="zem_slink freebase/en/kernel" title="Kernel (computing)" rel="wikipedia" href="http://en.wikipedia.org/wiki/Kernel_%28computing%29">kernel errors.

Running this monotonously every day is quite boring, so comes to rescue is logwatch. I have <a class="zem_slink freebase/en/fedora" title="Fedora" rel="homepage" href="http://fedoraproject.org/">Fedora <a class="zem_slink freebase/en/installation" title="Installation (computer programs)" rel="wikipedia" href="http://en.wikipedia.org/wiki/Installation_%28computer_programs%29">installation so I will talk about the location with respect to that so for your distribution it might be a little different.

gdialog on F11 – Leonidas

2010-06-01 1 min read Fedora

If you are using some old application or want to install some application that was developed quite some time back with GTK GUI, then you may find the application using gdialog. gdialog is no more available and is deprecated in Fedora and same functionality is provided by zenity. But the options to call zenity are slightly different so what do you do. I did a google search and found the following script. The credit of script is not mine and credit goes to ”Mike Newman mikegtn@gnome.org”
