Problem

If you try to access CSCS systems with the ftp  protocol, you will get a message similar to the following:

ftp: connect to address ...: Connection timed out

ftp: connect: Network is unreachable

Solution

The command ftp  is not allowed to connect on CSCS systems: you should be able to use rsync, scp or sftp to transfer your data instead.
Please check the availability of these commands on your local system using the Linux command which on your terminal.
For more information on their usage, please have a look at the corresponding manual pages with the command man.

Please note that large data transfers should use the data transfer service offered by CSCS.
