The FtpClientSocks5Proxy supports:

• SOCKS5 protocol as specified in RFC1928 spec
• SOCKS5 username/password authentication as specified RFC1929 spec

It has been tested against VSFTPD using Dante as a SOCKS proxy, both locally and against an Azure installation, where the FTP was running on a local address.

You will need to install Docker on your dev machine.

Docker commands to spin up a local copy for testing:

docker run -d --restart=always -p 9020:20 -p 9021:21 -p 9100-9110:9100-9110 -e FTP_USER=ftp -e FTP_PASS=ftp -e PASV_ADDRESS=172.18.144.1 -e PASV_MIN_PORT=9100 -e PASV_MAX_PORT=9110 -v /data/ftp:/home/vsftpd fauria/vsftpd

docker run -d -p 1080:1080 wernight/dante
