 +//This page describes the procedure to set up the tools for working directly on the srm storage. You may want to consider using the staging and download services provided by Astron if you just want to retrieve data from the archive: [[http://www.lofar.org/wiki/doku.php?id=public:lta_howto]].//
 +
 +//You might also be interested in the [[public:srmclientinstallation|portable package of GRID storage access tools]], which offers the same functionality but does not require root access.//
  
 The following documentation was developed for the installation of a GRID tools and certificates on an Ubuntu 12.04 system using a bash shell (using .bashrc as a configuration script). We have not tested the installation using csh derivatives but it is to be expected that not all scripts will work. Thanks to Martin van den Akker for providing notes of his installation procedure. The following documentation was developed for the installation of a GRID tools and certificates on an Ubuntu 12.04 system using a bash shell (using .bashrc as a configuration script).

 + 
 +===== Usage ===== 
 + 
 +This creates a proxy (valid for 48 hours, increase if needed) in your home directory: 
 +<file> 
 +voms-proxy-init -valid 48:00 -voms lofar:/lofar/user -out ~/.proxy 
 +</file> 
 + 
 +You can test that everything works by copying this file from surfsara to your working directory: 
 +<file> 
 +srmcp -server_mode=passive srm://srm.grid.sara.nl/pnfs/grid.sara.nl/data/lofar/ops/fifotest/file1M file://`pwd`/file1M 
 +</file> 
 + 
 +If your firewall allows incoming connections to non-standard ports, you can try this command without the server_mode option which will enable utilization of multiple streams to increase performance. 
 + 
 +If you have the [[public:grid_srm_software_installation#globus_client_software|gridftp client software]] installed and in your path, it provides superior performance as compared to the native JAVA gridftp client that is provided by srmcp. In order to utilize this, download {{:public:lta-url-copy.sh.gz|lta-url-copy.sh.gz}}, unzip it and use the command: 
 +<file> 
 +srmcp -use_urlcopy_script=true -urlcopy=./lta-url-copy.sh -server_mode=passive srm://srm.grid.sara.nl/pnfs/grid.sara.nl/data/lofar/ops/fifotest/file1M file://`pwd`/file1M 
 +</file> 
 +**Note:** You may have to force the use of TLS, (export GLOBUS_GSSAPI_FORCE_TLS=1 or in /etc/grid-security/gsi.conf set FORCE_TLS=true) to make this work.
