FTP Proxies
In some organizations, one may not be able to directly connect to the internet --- a proxy server may be implemented. (One can typically verify this by looking at one's connection settings in one's web browser.) This means that if one wants to connect to an FTP server outside of one's company, a special procedure needs to be used. To use FTP with a proxy server, the user would connect to their company's proxy server and then connect to an external FTP server. The implementation differs with each proxy server, so the user should ask their system administrator for specifics. However, as an example, if the proxy server accepts connections via the "USER" method, the user would do the following:
- On Windows, open a DOS "Command Prompt" under . On UNIX/Linux, use "xterm" (or whatever terminal program you like to use).
-
Change to the directory where your file(s) reside via
cd <directory>. -
Connect to your company's proxy server proxyserver via
ftp <proxyserver>. -
You will be prompted for a username. Enter username@ftpserver to
connect as username to
the external FTP site called ftpserver. For example, if
you wanted to log in anonymously on the ANSYS FTP site,
one would enter
anonymous@ftp.ansys.com. - Enter your password for the FTP server ftpserver. For anonymous logins, this would be your email address.
As noted above, there are different implementations for proxy servers, but the above is a typical method in which users would connect to external FTP sites through a proxy server.
