=File Transfer Protocol=

You may want to transfer files between department machines and your computer. The standard way is to ''scp'' via the terminal with commands :
UPLOAD :
scp -o ProxyCommand="ssh crsid@barbican.ch.cam.ac.uk nc machinename 22" LocalPath/FileName crsid@machinename.ch.cam.ac.uk:/RemotePath
DOWNLOAD :
scp -o ProxyCommand="ssh crsid@barbican.ch.cam.ac.uk nc machinename 22" crsid@machinename.ch.cam.ac.uk:/RemotePath/FileName LocalPath

However, a more convenient way is to set up a File Transfer Protocol (FTP) between machines. It can come with a graphic user interface, where you can drag and drop files from the department machine to your computer.

==Windows FTP==

I recommend the WinSCP software. You can download it from [https://winscp.net/eng/download.php here].
Once installed, click ''New Session'', and choose ''SFTP'' protocol with :
Hostname = machinename
Port number = 22
Username = crsid
Leave 'Password' entry empty.
Then click on ''Advanced...'', ''Tunnel'' tab, check the ''Connect through SSH tunnel'' tickbox and enter:
Hostname = barbican.ch.cam.ac.uk
Port number = 22
Username = crsid
Leave 'Password' entry empty.
Click ''OK'' and click ''Save'', and finally ''Login''. Enter your admitto password twice.
You can now navigate in the directories of the remote machine on the right tab, and of your local computer on the left tab, and you can transfer files between the two with a drag and drop. Enjoy !

==Mac/Linux FTP==

You can download FileZilla for [https://filezilla-project.org/download.php?platform=osx MacOS] or [https://filezilla-project.org/download.php?platform=linux64 linux].
The problem is that FileZilla does not support tunnel ssh. To open the connection, you need to use a ssh client like puTTY.
On MacOS please follow [https://phoenixnap.com/kb/install-putty-on-mac this guide].

On Linux you can do :
sudo apt-get install -y putty
Open it by typing ''putty'' on the terminal. The interface should open.
Type the following entries :

in the ''SSH/Tunnels'' tab :
Source Port = 3111
Destination = machinename:22
local
auto
and click ''Add''. (source port can be any number > 1024)

in the ''session'' tab :
Host Name = barbican.ch.cam.ac.uk
port = 22
connection type = SSH
Enter a name for this connection in the ''saved sessions'' entry, and click ''Save''.

Now click ''Open''.
A terminal should open, type your crsid and your admitto password, you're now logged into Barbican (it's normal that it's not your machine).

Now open FileZilla, and enter :
Host = sftp://localhost
username = crsid
password = admitto password
port = 3111
and click ''Quickconnect''. (port needs to be the same as source port in puTTY).

A window will open (Unknown host key), click ''OK''. Hopefully the connection is successful.

You can now navigate in the directories of the remote machine on the right tab, and of your local computer on the left tab, and you can transfer files between the two with a drag and drop. Enjoy !
