Handbook

Thank you for using Calculate Linux!

We have done for you the most convenient system for work using the tremendous opportunities which are incorporated in the package management system Portage. The system applies an administrative image, which collected the best software. Most programs have an open license, which allows you to install, distribute and modify the source code.

Network configuration

Configure the network Calculate Linux Desktop GNOME performs Networkmanager, in versions with the desktop KDE and XFCE using Wicd. Both programs have a graphical interface through which you can configure both wired and wireless network. When you load the program tries to raise the network interface and obtain an IP address from a DHCP server. Call the program using the icon in the upper right corner of the screen.

Network Configuration Calculate Directory Server and Calculate Linux Scratch is performed through a configuration file /etc/conf.d/net, help on setting up a network can be found in the file /usr/share/doc/openrc/net.example. After changing the settings, restart the network interface:

/etc/init.d/net.eth0 restart

Partitioning

The easiest way to install the distro - use an auto partitioning. If you plan to use the Calculate Linux in conjunction with other systems, you may need to allocate partitions on your hard drive by selecting the partition for installation.

Calculate Linux is installed in one section, a minimum capacity of 6 GB for the version with KDE and not less than 3 GB for XFCE. Recommended to use the partition in 10 GB. As a rule, need to allocate a swap partition (swap) with a size roughly equal to the amount of RAM. If the swap is already selected, then create a new one is not necessary. Good to have a separate partition for personal files (/home).

In Calculate Linux Desktop for partitioning a program Partitionmanager (a version of KDE) or Gparted (a version of XFCE). To Calculate Linux Scratch and Calculate Directory Server, use console utilities fdisk or cfdisk.

In order to view a list of available partitions, open a console as root user and type:

fdisk -l

If you have never used Linux, you need a little time trying to get used to the name of partition as sda1, sda2, ... instead of the usual c:, d:.

You can also use already prepared to share, or create it from Windows. Try to identify it correctly in Linux, based on the sequence location and size. Typically the C: drive corresponds to sda1, the D: drive, respectively sda2.

Installation

During the installation of the system meets the program Calculate. If you do not calculate the parameters, the program will ask you to specify the partition on which to install the system. Calculate can perform a partition of the disk only if you are willing to allocate the entire hard disk for the system.

To install a second hard disk partition, you can simply do:

calculate -d /dev/sda2

To install the hard drive and removing the old data:

calculate -d /dev/sda

Program expands stage4 system image and adjusts through the template files. Essentially it is the same configuration files that contain program variables. Calculate determines the type of equipment and machinery fills these variable values. You can view a list of variables following the "calculate -v". The values of variables that can change noted in the list of flag [w], variables are read-only labeled [r]. To change the values of variables, use the option --set-variable-name.

List of most frequently used options installed

--disk=/dev/sda2 - partition to install (default will be offered part sda2);

--set-format = reiserfs (ext4, ext3, ext2, xfs, jfs) - format file system;

--set-composite = on (off) - the inclusion of a composite mode;

--set-type = hdd (flash, usb-hdd) - media type, set in the case of incorrect identification.

Other options

--set-hostname = linux - computer's network name, the default 'calculate';

--set-video_resolution = 1280x1024 (1024x768, 1152x864, 1280x800, etc.) - the screen resolution, if you use the screen resolution misidentified;

--set-mbr = off - do not modify the MBR during installation;

--set-erase = off - do not format the partition before installing;

--set-march = i686 (x86_64) - set the distribution for 32 or 64-bit processor architecture, is not true for CD installation disk.

Installing on USB-Flash

When installing the system, you can specify the device USB-Flash and the system will be installed on your stick. Example:

calculate -d /dev/sdb

Note that when you install quests, conundrums will be formatted to the file system FAT32. Before installing the need to save all your data.

In this example, quests, conundrums listed as disk sdb. To know that there is a hard drive, run the command fdisk -l to see all the available devices and partitions.

If your quests, conundrums defined as ssd drive, you can add an option "--set-type=flash" - change the type of media to Flash

The first launch

After installing the CLD, CLDX and CLSG in the system are two users: root and guest. Access to the graphical session can get the user guest. Use the username guest with password guest to login.

In CLS default no graphical invitation to enter the password. After installation you can log in as root, run the graphical session tvm can use the command startx.

For root user, use the command "su". Create users described in detail on the project site.

By default, you can log into the system remotely using ssh only by root. You can add a space to other users or to replace the root user edit the options AllowUsers file /etc/ssh/sshd_config.

Update

You can update the system virtually unlimited number of times, using Portage manager install programs emerge. First update Portage and Calculate overlay by running:

eix-sync

After that, you can upgrade existing or install new versions of programs, using the program emerge.

New versions Calculate Linux come with an interval of 2-3 months. If you used the disk to install a nutshell, or have a second partition free for at least 6 GB, you can download an ISO file system in directory /usr/calculate/share/linux and run update:

calculate -d /dev/sdaX

Where instead sdaX free substitute for the installation partition.

Most of the configuration of the current system, such as user accounts, network settings, mount point, the screen resolution and others will be transferred to the new system.

Help

If your installation has any difficulties, or you want to share their impressions, visit the IRC channel #calculate (server FreeNode) user community Calculate Linux. It's enough to use Xchat icon on your desktop.
