< Getting started with SweGrid

Installing from package repositories

The easiest way of installing the ARC middleware is by using the available apt- and yum-repositories. Read this information for setting up the repositories:

http://download.nordugrid.org/repos-12.05.html

Installing the ARC middleware can now be done using the following commands:

 sudo yum install nordugrid-arc-client-tools

or

 sudo apt-get update
 sudo apt-get install nordugrid-arc-client-tools

Client configuration

The configuration file for ARC is located in $HOME/.arc/client.conf. A typical configuration file for SweGrid is shown below:

[common]
defaultservices=index:ARC0:ldap://index1.swegrid.se:2135/Mds-Vo-name=SweGrid,o=grid index:ARC0:ldap://index2.swegrid.se:2135/Mds-Vo-name=SweGrid,o=grid

The giis attribute sets the information system URL:s used for job brokering and information. The debug attribute sets the amount of debug messages shown when using the ARC command line tools. debug=0 turns debug messages off. timeout is the timeout value in seconds for how long the commandline tools should wait for a response from a resource before giving up.

More configuration options are available. Please check the NorduGrid ARC Client User Guide for more information.

The installation can be verified using the arcinfo command. If everything is configured correctly and you have been added to the SweGrid VO the arcinfo command you display the following output:
