FAQs

How do I login with a FTP proxy?

Create a new instance of one of the proxy classes and then use any of the available API to control the connection.

For example code see above.

How does the SOCKS5 proxy work?

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.

How do I test a connection using a SOCKS5 proxy?

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
