 ====== GRID storage access tools installation ======
-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.
+**//:!: Several sections in this page are deprecated or obsolete. In particular, users are advised to avoid SRM clients and globus client software and instead look into using the [[https://dmc-docs.web.cern.ch/dmc-docs/gfal2/gfal2.html|gfal]] client library and command line tools. SURF provides good [[https://doc.grid.surfsara.nl/en/latest/Pages/Advanced/grid_storage.html|documentation on usage of grid storage client software]].// **

+===== 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.
