You can only ftp to the following CSE hosts: pita, inferno, mangal and humus. Note: undergraduate students can only access pita and inferno.

In order to ftp to one of the allowed CSE hosts, you must go through the CSE gateway. The following is the procedure to ftp to a CSE host:

  1. Ftp to gw.cs.huji.ac.il.
  2. Login using your CSE username and your OTP password. If you were successful, the gateway will respond 230 User authenticated to proxy.
  3. Enter: user USERNAME@CSEHOST. For example: user rafa@pita. If you were successful, you will get the response: 230 User rafa logged in.
  4. Now proceed with regular ftp commands.

Graphical FTP

The best way to use FTP is from the command line. It is faster and simpler. Additionaly most graphical FTP clients can't connect to CSE since we use a gateway/proxy. However, if you really really want to use a graphical FTP client, here are some instructions.

Unix

Install gFTP, open it and do the following steps exactly (please read it once before connecting).

  1. Write the host you want to connect to (like pita, inferno or any other), your username, and your UNIX password (not OTP). Fill all this data in the right sections below the menu bar. (Do not connect yet.)
  2. On the upper menu, go to FTP -> Options, choose the FTP tab, and give the following info:
    • Proxy hostname: gw.cs.huji.ac.il
    • Port: 21
    • Proxy username: your CS username (the same from step 1)
    • Proxy server type: choose user@host from the menu
    • Proxy password: your OTP
  3. Then press OK and immediately connect by clicking the computers icon on the upper left side of the client (left to the host you wrote on step 1). This step should be done quickly before the OTP is invalidated.

Windows

You should be care of any VPN programs installed on your computer that can cause to "FTP over Gateway" disfunction.

FTP'ing with Total Commander (shareware)

Firstly, download Total Commander, file manager.
It is 'two panel' Norton Commander like file manager for windows. It works with all versions of windows - from windows 3.1 to 7. Current version is 7.50a. It takes 3.0MB and also can be installed on disk on key.

Now run it from desktop icon or from start menu. Press 1/2/3 what it asking for. You will see two panels with menu under top window bar (File, Mark, etc...).

  • Go to 'Net' -> 'Ftp Connect' (Ctrl+F)

  • Choose 'New connection...' (Alt+N)

  • Session: CSE
  • Host name: inferno
  • User name: <your user name>
  • Password: <your unix password>
  • Use firewall (proxy server), check it and click 'Change'

On new window 'Firewall settings':

  • 'Connect method -> choose 'Send command USER user@hostname'
  • 'Firewall logon' ->
  • Host name: gw.cs.huji.ac.il
  • User name: <your user name>
  • Password: <leave blank> <= that means don't write anything so it will ask every time OTP password.
  • Click 'Ok'

In window 'Connect to ftp server', choose saved session (CSE in our case), Click Connect on right side, in popup window write your OTP password and you will see on one of right or left panel your homedir and on other side - your computer files!


Good luck!
