Logwatch on Ubuntu Desktop/Server

Logwatch is an Ubuntu modular log analyzer that runs every night and mails you the results. It can also be run from command line. The output is by service and you can limit the output to one particular service. The subscripts which are responsible for the output, mostly convert the raw log lines in structured format.
Logwatch generally ignores the time component in the output, that means, you will know that the reported event was logged in the requested range of time, but you will have to go to the raw log files to get the exact details.
Install logwatch using the following command:

sudo apt-get install logwatch

This will install all the required packages

Configuring Logwatch:

first you need to make sure you server is able to send the mails outside you can do this using postfix with SMTP server configuration.

sudo nano /usr/share/logwatch/default.conf/logwatch.conf

Change the following information:

Output = mail
Format = html
MailTo = test@gmail.com

Save and exit the file

If you want to know more available options check logcheck manpage using the following command from your terminal:

man logcheck

Now edit the 00logwatch file

sudo nano /etc/cron.daily/00logwatch

How to create your personalized Linux OS using SUSE Studio

This week, in our Linux Page (in Spanish) we uploaded a brief post about SUSE Studio an online service which allows you to create new distribution based on openSUSE 11.2. The online OS builder allows you to choose between 32 bit or 64 bit system based on SUSE, GNOME, KDE, Minimal X or text only Server. In the next menu you will be asked to choose all the software you prefer (7,876 different packages). After this, you can also choose and personalize, for example: language, keyboard, network, firewall and users. Moreover, you can personalize the boot-up and all the programs you want to automatically autostart. SUSE Studio is very interesting and allows you to create the best Linux OX for all your needs.

RepoGen: how to create and keep up-to-date your Software Sources on Ubuntu 8.04, 8.10, 9.04 and 9.10!

This week, in our Linux Page (in Spanish) we added a post about a new fantastic online service to manage and add software sources to your Sources List (System – Administration – Software Sources). Adding the right repository sources in Ubuntu is essential for a more practical and fast management of your OS. In fact, using the correct sources list you can be sure that your system is always updated and safe. RepoGen has been created for all these reasons. It also automatically compiles all the necessary GPG keys and you have just to add them (one by one) running the suggested command in the Terminal. We tested RepoGen on two different PCs running both Ubuntu 8.04 & Ubuntu 9.04 and were able to update our Software Sources in less of 15 minutes and without discovering a single problem. To conclude we strongly believe that RepoGen is an online service that can help you to save a lot of time and keep your Ubuntu always up-to-date! Strongly recommended! AddThis mp3 link
