Introduction

JADE can establish connections that are routed over proxies.

However the type of authentication allowed and the protocol used for the 'main' connection have to be considered when selecting a proxy.

File Transfer Protocols and Proxy Protocols

The following proxy protocols are available:

• HTTP Proxy
• SOCKS4 Proxy
• SOCKS5 Proxy

Different Proxy protocols can be used for different file transfer protocols. For example:

• HTTP proxies can be used with the FTP, HTTP, HTTPS and WebDAV protocols.
• SOCKS4 proxies can be used with FTP, FTPS and SFTP protocols.
• SOCKS5 proxies can be used with FTP, FTPS and SFTP protocols.
• See the JADE Parameter Reference - Reusable Elements - Proxy for more detailed information.

Local or remote Proxy Connection and Authentication

colour Yellow title Remote ?

A proxy can be installed on any host in the network and is identified by its connection parameters.

Some Proxy protocols - e.g. SOCKS5 - allow authentication credentials to be specified.

Proxies connections are all configured using BasicConnection and BasicAuthentication elements - SSHAuthentication is not possible.

Specifying Proxy Connections

Connections to source hosts, jump hosts or target systems can be routed by a Proxyproxy.

• Proxies are defined for file transfer protocols and connections:
  
  • In the JADE XML configuration schema proxy elements are children of ProtocolFragments. For example,
    • the ProxyForSFTP element is a child of the SFTPFragment
    • two separate ProtocolFragments would need to be configured if it was required to define a direct connection to a server and a connection over a proxy.
• A Proxy configuration consists of:
  • a connection to the host where the Proxy proxy is located
  • and optionally credentials for authentication

File Transfer Protocols and Proxy Protocols

Different file transfer protocols, such as FTP, SFTP etc., make use of different Proxy protocols. For example:

• FTP can be used with all Proxy protocols.
• SFTP can be used with SOCKS4 and SOCKS5 Proxy protocols.
• Evidence for applicable Proxy protocols is stated with the file transfer protocols in the JADE - Reference Documentation - Parameter Reference

The following proxy protocols are available:

Local or remote Proxy Connection

A proxy can be installed on any host in the network and is identified by its connection parameters.

Proxy Authentication

Some Proxy protocols allow to specify credentials for authentication, e.g. SOCKS5.

• • , which is specified with a BasicConnection element and
  • credentials for authentication (optional), specified using a BasicAuthentication element

The XML element hierarchy used to specify a proxy for - here - an SFTP connecton are:

• SFTPFragment
  • BasicConnection
  • SSHAuthentication
  • ProxyForSFTP (optional)
    
    • SOCKS4Proxy
      • BasicConnection
        • Hostname
        • Port
    • SOCKS5Proxy
      • BasicConnection
        • Hostname
        • Port (optional)
      • BasicAuthentication
        • Account
        • Password (optional)
  • other optional elements
