    have you considered secure copy? It is a function of SSH (basically secure telnet). The syntax is beyond easy.

    scp [-pr] [userid@][source host:][path to file] [userid@][destination host:][path to file]


    From Unix to Unix

    You want to copy files /home/vanacker/*.html (all files in that directory that end in ".html") on CPC Unix host to your public_html subdirectory on ATN's Isis system and you are logged into talltoad already. At the talltoad unix prompt, you would enter:

    scp /home/vanacker/*.html

    You would then be prompted for your passwd for the vanacker account on Isis.

    From Unix to PC

    You want to copy a file /htdocs/fred.html on Unix host into the current directory on your desktop PC, and your userid on is "charlie". In a DOS window, you would enter:

    scp .

    Here, the "." corresponds to the present working directory in your DOS window.
    You would then be prompted for the passwd for the charlie account on

    From PC to Unix

    You want to copy a file D:\myfiles\work.ppt on your desktop PC to your home directory on statapps, the ATN statistical computing platform, and your userid on statapps is "mmouse". In a DOS window, you would enter:

    scp D:\myfiles\work.ppt

    You would then be prompted for the passwd for the mmouse account on

    You cannot transfer files over FTP using a telnet client. This is because the FTP protocol uses two connections - one for control and another for data. What you have established above is the control connection, the data connection needs to be established independently.

    Can you really not use a FTP client?

    Sounds weird.

    Slarty is correct

    ....if your interested, have a read about how Active and Passive FTP work:
