How to Download/Upload File Through a FTP Proxy Server With 'curl'

This help is for linux machines behind a FTP proxy.. (Note: Squid is not a true FTP Proxy server)

Say the proxy server is squid configured to be running on ' 192.168.0.10' Port '3128'
then some of the things we can do..

* List Files On FTP Server

curl --proxy 192.168.0.10:3128 ftp://qcd:onevision@sharethespace.com:21

* Download a file

curl -o STSServerInstaller.exe --proxy 192.168.0.10:3128 ftp://qcd:onevision@sharethespace.com:21/STSServerInstaller.exe

* Upload multiple files to the ftp server..

curl --upload-file "{rarlinux-3.6.0.tar.gz,vmlogo.xpm}" --verbose --proxy 192.168.0.10:3128 ftp://qcd:onevision@sharethespace.com:21

Note: We are uploading two files ie. rarlinux-3.6.0.tar.gz and vmlogo.xpm, similarly we can state more files, with a comma seperated list.

* We can also give the username/ password in options which is much safer than using it on the URL.

curl --upload-file "{rarlinux-3.6.0.tar.gz ,vmlogo.xpm}" --verbose --proxy 192.168.0.10:3128 -u qcd:onevision ftp://sharethespace.com:21
curl -o STSServerInstaller.exe --proxy 192.168.0.10:3128 -u qcd:onevision ftp://sharethespace.com:21/STSServerInstaller.exe
curl --proxy 192.168.0.10:3128 qcd:onevision ftp://sharethespace.com:21/path/to/file


CURL is a free GPL'ed Utility available on various platforms. in linux it comes by default.. in case its not there, please visit http://curl.haxx.se/download.html and download the version required for your platform. Windows Binary download is here

Note: The normal FTP client (Shell or ftp on dos prompt) does not work with ftp proxy servers.
