Main Page - Caos Linux Wiki

The Caos Linux Project

Caos Linux is a community-assembled operating system specially developed with nodes, servers, and appliances in mind. Caos Linux is fast, stable, and secure, versatilely scaling from HPC clusters to web appliances. It even functions well as a lean desktop workstation. Caos Linux is up to date, RPM compatible, Intel Cluster Ready, and integrates perfectly with Perceus, Infiscale's cluster provisioning software.

Our Wiki is the instruction database for our user community. Everyday users are encouraged to create and edit instructions, descriptions, and "HowTo" walkthroughs of the installation, configuration, administration, and use of Caos Linux. Space is provided for developer collaboration as well as information on how to join in the effort.

Getting Started

15: Once booted you will be presented with the Caos NSA login prompt. Here is where you enter the default account created by the installer, that was recommended to be written down in step 12. The user name is 'admin' and the password is a randomly generated password of three numbers and four letters. Once that is entered you are fully logged into your new Caos Linux NSA system. Additional information about Caos NSA is located in the home directory. If additional system configurations need to be made or software packages added, sidekick is the best place to start. Sidekick works directly on the config files, so it can be used in addition to fully manual configuration techniques. To run sidekick enter 'sidekick' as root or 'sudo sidekick' from an admin account.

Congratulations and best wishes with your experience using Caos NSA!

5 System Configuration using Sidekick
Written for Caos Linux 2 (but looks similar to NSA Sidekick screens).

System Configuration using Sidekick

In the next part you will be greeted with the system config called Sidekick as seen below:

I suggest you go in order. Press enter to do a Hardware detect of all the hardware on your computer. Simple Right? Next is the system name. Here you can define the Domain name and hostname of your computer. After this is the Network Device Config setup as seen below:

Press enter to configure the device listed above. Enter yes for the device to be active and select dhcp if you use a router (which uses the dhcp protocol) and static if you have a static ip. Select dhcp if you don't know which one to choose. Press d after you are done. Next is setting the date and time. I found that if I probe the current time over the internet it gives me the wrong time. But as usual there is the option to specify the date and time yourself. After that is setting the timezone. This screen is pretty self explanatory, if its not, pull up a map of the world and find out where you are. hehe ;)

Network Repository is the next option. You should see URL to mirror : http://mirror.caosity.org/cAos-2

Press enter to set this as your default repository. There is no need to change this...yet. In the next screen you will be given the option of choosing which repository to use. There are three options to pick from:

stable - repository where these packages are tested to be fully working with caos

current - repository is where the packages have no bugs but are not exactly fully deemed stable

testing - repository is the testing repository where you can get the latest cutting edge software but there may be bugs in them

System Roles is the next option in sidekick where you define what you want caos to do for you. Here you define the package options you want to install as seen below:

Select the package options you would like to install by selecting them with the spacebar and when you are done press d to continue installing the packages you selected. You will need the Default at least selected.

If you get a message on the screen that says Error: failure No more mirrors to try

don't panic, thats sidekicks way of telling you that you have a faulty connection and it disconnected while it was downloading. Press enter and it'll bring you back to the sidekick main screen. Now scroll up one back up to System Roles option on sidekick and select your options again and re-try.

Now wait for it to finish and after its done it should bring you back to the sidekick main menu.

The next option on the menu is Start/Stop services. Default services are already checked but if you have a laptop i suggest apmd as well. If you are using caos as a firewall i suggest iptables and if you are running a Raid i suggest mdmonitor. I suggest everyone check the last option on that list, enable a daily run of yum.

Finished!

After that you need to set the Root password for caos. When you are done review your settings and press d to save and exit sidekick. You can always start sidekick again by typing sidekick at the prompt.

Pat yourself on the back for a job well done! now it will reboot and depending on what package options you picked in sidekick you will either be greeted with a console based user and password prompt(runlevel 3), or another GUI(graphical user interface) login screen(runlevel 5). You are now done ;) congrats!
