Transferring single files from Unix

1. Create a file named 'config' in the folder .shh in your home directory
2. Add the following lines to the file 'config'
   Host desydata
   ProxyCommand ssh -Y <account>@bastion.desy.de /bin/nc p3wgs6.desy.de %p
   
   Notes:
   • $<$account$>$ has to replaced by a valid account name, either a DESY staff or a beamtime account (fs******)
   • Depending on the unix system used, 'nc' might be in another location or may even have a different name, try e.g. 'which nc' or 'which netcat' to find the appropriate binary location
   • 'desydata' is an alias and can be chosen freely
3. One should now be able to transfer your data or connect from outside DESY, e.g.
   rsync -tvr $<$account$>$@desydata:$<$path_to_your_data$>$ $<$path_to_target_dir$>$
   where $<$path_to_your_data$>$ is the source directory, e.g. /pnfs/desy.de/petra3/disk/user/$<$AppID$>$... and $<$path_to_target_dir$>$ is the target directory, e.g. /mydir/
   

   Please note:

   • that one has to provide your password twice, one time to establish the tunnel and one time to log into the server
   • that the options for rsync given in the example are just for demo and do not necessarily reflect your needs.
