Putty Tutorial

Logging on and transfering files for Windows Users

Generally we advise Windows Users to use Putty. Putty is what is called a "terminal programme" that you use to connect to VPAC systems from your own (desktop or laptop) computer. Putty is free and very easy to install.

Putty is available from: http://www.chiark.greenend.org.uk/~sgtatham/putty/

It probable that all you need is putty.exe, its quite small and does not need to be installed, just save it to your desktop and double click when you need it.

Configuring Putty

putty_config
Please note the image says "tango". This is the name of the old VPAC cluster. In the 'Host Name' box, enter the server you want to connect to (e.g., trifid.vpac.org) and select ssh from the 'Connection type' radio button. Its useful to enter a session name, (e.g., "Trifid") in the above case and save it so you don't need to remember the details next time.

Generally, the other Putty settings will be fine as they are. One thing you might need if you are going to be using XWindows (to display a graphical interface from VPAC on your desktop) is to turn on XForwarding. You will also need some sort of "XWindows Server" installed on your desktop, perhaps XWin32 or Exceed3D. A possible free option is XMing, http://www.straightrunning.com/XmingNotes/

When you connect, you will be asked to verify the host key when connecting for the first time when a box pops up. Say 'yes', you will only see the first time you connect to a particular machine.

Note that the public key for trifid is 19:41:15:a4:01:4a:a4:63:13:93:cd:4d:05:f4:ba:a5 .

Transferring files, winscp

WinSCP is most suited for general use and we will concentrate on it here.

WinSCP is available from: http://winscp.net

WinSCP (Windows Secure Copy) is a graphical open source SFTP (and FTP) client for MS-Windows. It uses ssh and supports SCP (secure copy). It can also provide basic file management and remote editing.

Transferring files, PSCP
If you are going to be scripting transfers or moving a large number of files, perhaps you need to investigate PSCP. PSCP is available from the same site as Putty mentioned above and is a requirement for a number of systems that rely on files being moved back and forth automatically.

Transferring files, Rsync
RSync provides a way to keep two repositories of files "in sync", one of these repositories may be on your desktop, the other your home directory at VPAC. A tutorial on using rsync as a backup tool can be found at

Rsync for MS-Windows at http://optics.ph.unimelb.edu.au/help/rsync/rsync_pc1.html
