As ppelx.physics.gla.ac.uk can now be accessed directly the information below on doing a direct file copy is now redundant. The orginal script and instructions are below incase they can help in other double hop situations.
As the ppe linux machines are not directly accessible from outside copying files to the ppe systems from outside would seem to require first copying a file to login.physics.gla.ac.uk then logging into login.physics.gla.ac.uk to copy the file to the ppe systems. From a linux system this double hop can be avoided using by using a wrapper script to scp and some ssh configuration options. | ||||||||
