Download a file from FTP via proxy with Ruby-CodePudding

I have an app running on Heroku, and I need to download a file from an FTP. But I need to do it using a fixed IP. I´m using www.quotaguard.com to have fixed IPs.

But I can´t get it working.

Does anyone has a Ruby example to download a file from an FTP via a proxy server (quotaguard).

Both the proxy server and the FTP require username and password.

I´ve tried everything, using Ruby. And also calling wget from system to initiate a download, but wget apparently doesn´t go via the proxy. Also checked many posts, but no success so far.

I´m using Ruby 2.4.5

Thanks for any comments.

We've seen a few customers do this before with the socksify gem.

require 'socksify'

proxy = URI(ENV['QUOTAGUARDSTATIC_URL'])

TCPSocket::socks_username = proxy.user
TCPSocket::socks_password = proxy.password
Socksify::proxy(proxy.hostname, 1080) do |soc|
  # do your FTP stuff in here
end

If that doesn't do it, post the errors you're seeing and we'll help get this running for you.

Thank you QuotaGuard. Socksify is not maintained and really old, we gave it a try but didn´t want to spend much time on it.

We actually managed to get this working with curl. You can call it within Heroku as well.

Here´s the command in case anyone wonders.

curl -x socks5h://socksproxyurl 'ftp://theftp/some.pdf' --user "ftp_user:ftp_pass" -o some.pdf
