-You can use //fuse// (the userspace filesystem driver) to mount any remote filesystem which you have ssh access to. You can use this to access files from other systems outside of Tate Lab. For example:+The security model of Unix NFS is too weak to permit exporting it to any systems which are not part of the Physics cluster. Some alternative methods of transferring data include...

 +You can use //fuse// (the userspace filesystem driver) to mount any remote filesystem which you have ssh access to. Although this is not a high-performance solution, you can use this to access files from non-Physics linux systems. For example:
  
   mkdir ~/mnt  #create a place to put it, can be called anything you want.   mkdir ~/mnt  #create a place to put it, can be called anything you want.
