YADE should support use of a proxy for FTP and SFTP protocols

Current Situation

• Proxy support is provided exclusively for the proxy protocol HTTP and the file transfer protocols WebDAV and HTTP.

Desired Situation

• Use of a proxy should be possible for the file transfer protocols FTP and SFTP too.

Resolution

• Use of a proxy
  • with the HTTP protocol is supported for the file transfer protocols WebDAV, HTTP, HTTPS, FTP and SFTP.
  • with the SOCKS4 and SOCKS5 protocols is supported for the file transfer protocols FTP and SFTP.

Parameterization

• The following parameters are added to connect to a source host via a proxy:
  • source_proxy_protocol = http|socks4|socks5
  • source_proxy_host
  • source_proxy_port
  • source_proxy_user
  • source_proxy_password
• The above parameters can be used in a similar way for connections to a target host via a proxy (by replacing the source_ prefix by target_).
