====== Connecting ======
The cluster has the network name **kraken** (kraken.it.cas.cz).

The SSH protocol is used to communicate with the cluster. 
You must have a program (SSH client) installed on your computer that allows communication in this protocol.

The name "kraken" refers to the administrative node of the cluster, the compute nodes themselves are controlled via [[computing:cluster:fronty:start|queue system]].

\\
=== Linux ===

In Linux, an SSH client is usually included in the installation.
To log in to the server, use the command in xterminal:

  ssh -Y user@kraken
/,You can omit the -Y parameter if you don't need graphics redirection,/


=== Windows ===

In Windows, the SSH client is not part of the system, so you need to use a separate program.
The recommended programs to use are:
  * {{:computing:cluster:navody:ico_putty.png?direct |}}[[http://www.putty.org|PuTTY]] -- the most widely used client for windows. <wrap download>{{:computing:cluster:navody:putty_068_32bit.exe.zip|32bit verze}}</wrap> <wrap download>{{:computing:cluster:navody:putty_068_64bit.exe.zip|64bit verze}}</wrap>

  * {{:computing:cluster:navody:ico_kitty.png?direct |}}[[http://www.9bis.net/kitty/|KiTTY]] -- a fork of PuTTY with several extensions. <wrap download>{{:computing:cluster:navody:kitty.exe.zip|KiTTY}}</wrap>

You must have an X server installed to run graphical applications.
  * {{:computing:cluster:navody:ico_x.png?direct |}}[[http://vcxsrv.sourceforge.net|VcXsrv Windows X Server]] -- open source version of the X server available in both 32 and 64-bit versions.
    * for Windows Vista, 7, 8.1 -- <wrap download>[[http://sourceforge.net/projects/vcxsrv/files/vcxsrv/|download latest version]]</wrap>
    * for Windows XP -- <wrap download>[[http://sourceforge.net/projects/vcxsrv/files/vcxsrv/1.14.2.1/|download version 1.4.2.1]]</wrap>

  * [[:computing:cluster:pripojeni:vnejsi|outside the IT]] 


====== File transfer ======

You can use any of the following programs to conveniently transfer files between your computer and the server:

  * {{:computing:cluster:ico_scp2.png?direct |}}[[:computing:cluster:pripojeni:WinSCP]]
   
  * {{:computing:cluster:ico_far.png?direct |}}[[:computing:cluster:pripojeni:FAR manager]]
  
  * {{:computing:cluster:ico_tc.png?direct |}}[[:computing:cluster:pripojeni:TC|Total Commander]]
