Anonymous ftp Upload

Appropriately authorised local users are able to upload into and download from the group space while external users
will only be able to upload files into the directory, using anonymous FTP. They will not be able to view, remove or
modify the contents of the directory. The group is arranged so that the external user has no knowledge of the
directory's contents, making it a "blind" upload, therefore offering a high degree of security.

• To set up a group
  
• Connecting to ftp
  
• If you are an external user (with just write access)
  
• If you are a Local user (with read/write access)
  
• The file system
  

To set up a group

• a) Decide which local CUED users should have full access to the filespace
• b) Decide on an appropriate name for the Group (in consultation with the DPO Computer Operators)

Connecting to ftp

• - ftp ftp.eng.cam.ac.uk
• - Name - > anonymous
• - Password -> 'user email address'

If you are an external user (with just write access)

• cd /pub/upload/'<.GROUPNAME.>'
• put <.FILENAME.>

If you are a Local user (with read/write access)

cd /var/ftp/pub/upload/<.GROUPNAME.>

and then read, copy, and/or delete any files they find there.

--------------------------------------------------------------------------------------------------------------

Alternatively, people with CUED user accounts who are in the appropriate group can ftp to
ftp.eng.cam.ac.uk with their CUED username/password, and (similarly)

cd /var/ftp/pub/upload/<.GROUPNAME.>

and then download, and/or delete any files they find there.
You can access the filespace directly by logging into club and doing

cd /var/ftp........

then use Unix commands (cp, rcp, rm, etc..) as required.

Informing external users

You will need to email your external users with instructions on how to upload files and where to upload them to.
We have a preformatted email explaining the procedure for uploading and which directory is available for
external users to upload files into.

The File System

Preformatted email

Dear ########,

I have set you up so that you have access to the anonymous ftp upload facility.
This allows you to make 'blind' uploads into a CUED group directory.

They are 'blind' uploads as you have no idea as to what other files are in the group and as a result, will have no file
manipulation access.

To access the group, type 'ftp ftp.eng.cam.ac.uk' then 'anonymous' when asked for a user or a name.
Then use your 'user email address' when a password is requested.

To get to the correct directory, type
cd /pub/upload/GROUPNAME (where GROUPNAME is *********)

As already mentioned, you are unable to see, download, overwrite or delete anything in this directory.

You may only upload by
put FILENAME (where FILENAME is the name of your file)

Logout with 'bye'

This filesystem on which the upload directory resides is 2GB , and files are deleted 14 days after they're uploaded.
