Training/Transferring Data

Methods

Small to medium amounts of data

This can be carried out using a number of SFTP-styled packages such as sftp, scp, rsync, and Filezilla to name a few. Filezilla can be downloaded as a Windows application and may be more suitable for people who prefer a Windows environment, rather than the command line.

Note FTP (insecure) is disabled on viper.hull.ac.uk and SFTP (secure FTP) is the recommended method.

Large to a huge amount of data (100GB +)

To avoid excessive network congestion and the long period of time to transfer such data please raise a support ticket for further details. This may typically involve connecting a USB data drive directly to VIPER to copy the data quickly into your user area.

OneDrive to Viper

With the University using MS OneDrive, it is possible to copy files to Viper. For multiple files, zip your files up on OneDrive first (considerably easier), as shown here:

From OneDrive to Viper

Starting with the zipped file MyData.zip on OneDrive, copied previously and compressed from local storage. Click on the share icon or options for the file here (three horizontal dots) and select share. Then Click on Copy On your Viper console application, type wget and paste in the copied link and follow with -O yourfilename (otherwise Linux will name the file to the OneDrive link - argh!) And here is the received file Remember to un-share the file on OneDrive and use unzip (if required) on Linux to restore the file structure.

Universal

The following can only be performed on Windows after installing MobaXterm or PuTTY.

The example user is user1; you will need to enter your own username here:
