Connect from Linux command line to FTP server with proxy

Question

I want to connect to an FTP server from the Linux command line. The server is configured behind a proxy.

If I call:

echo $ftp_proxy 

I get a result like this:

abc.def.ghi.jkl:8080

If I call:

ftp -pn $ftp_proxy

I get a unknown host error.

How can I connect to the FTP server using the Linux command line?

Answer 1

When using an address:port and ftp, you cannot use the colon. ftp is expecting two parameters as ftp -pn host port.

Use a space instead of the colon.

example="abc.def.ghi 8080"
ftp -pn $example
