There is no system in place to directly access files saved when working in the Linux labs, to do so you must first connect to the externally facing server Helios, from there connect to server Ouranos and then drag the files you want back with you to your computer. This is the basic process:

1. Connect to Helios
2. Connect to Ouranos
3. Pack up the folder you want
4. Disconnect from Ouranos
5. Copy file Ouranos > Helios
6. Disconnect from Helios
7. Copy file Helios > your computer

Windows

• Open PuTTY
• Connect to Helios using the following Host Name

helios.hud.ac.uk

• Connect to Ouranos

ssh ouranos

• Find the folder you need
• Pack the folder up into a single file

tar -czf new_filename.tar.gz directory_name

• Disconnect from Ouranos

exit

• Connect to Ouranos with FTP, find and copy the file you just made from Ouranos to Helios

sftp ouranos

get new_filename.tar.gz

(Hint: While using FTP interactively, use the usual Unix commands for navigating the file structure, ls, cd etc.)

• Disconnect from Helios

exit

• Use a FTP client to copy the file you just made from Helios to your computer, I recommend FileZilla. Use the following as the host:

sftp://helios.hud.ac.uk

(Port: Leave blank)

• Extract your files, most common archiving utilities for Windows should be able to extract from TAR files.

Linux/OS X

• Open a new Terminal
• Connect to Helios with your student ID

ssh u0899999@helios.hud.ac.uk

• Connect to Ouranos

ssh ouranos

• Find the folder you need
• Pack the folder up into a single file

tar -czf new_filename.tar.gz directory_name

• Disconnect from Ouranos

exit

• Connect to Ouranos with FTP, find and copy the file you just made from Ouranos to Helios

sftp ouranos

get new_filename.tar.gz

(Hint: While using FTP interactively, use the usual Unix commands for navigating the file structure, ls, cd etc.)

• Disconnect from Helios

exit

• Connect to Helios with FTP, find and copy the file you just made from Helios to your computer

sftp u0899999@helios.hud.ac.uk

get new_filename.tar.gz

• Disconnect from Helios

exit

• Extract your files

tar -xvf new_filename.tar.gz
