Introduction
- A jump host is a server over which traffic to and from a network is channeled, see Jump Host Architecture.
- Jump hosts can be used to provide a secure method of file transfer across network boundaries by not allowing direct transfer over the boundary.
- DMZs (demilitarized zones) are a common form of jump hosts.
- JADE YADE can be used to carry out file transfer via a jump host, once a JADE YADE Client has been installed on the jump host.
- Different protocols can be used for transfer between the source host and the jump host than for the transfer between the jump host and the target host. To this end, different parameter sets are defined in the JADE YADE configuration for each part of the transfer.

Schematic Diagram
The following diagram shows schematically how files are sent via the Internet from one network with a DMZ to another network with a DMZ.
Configuration
The XML element hierarchy for the configuration of a jump host is shown below for a Copy operation with the jump host on the target side of the operation:
...
Neither configuration data nor log files are stored by JADE YADE on the jump host.
Element Restrictions
Element Use Restrictions
Only a single JumpFragment can be specified as part of a connection fragment element.
Jump hosts cannot be specified as part of AlternativeFragment elements.
Parameter Restrictions
- BasicConnection and SSHAuthentication elements must be specified for every JumpFragment. URL- and HTTPConnections and BasicAuthentication are not allowed.
- Password or Publickey authentication can be specified
- Only SFTP proxies can be used with JumpFragment elements, meaning that only proxies that use the SOCKS4 and SOCKS5 protocols can be specified.
Parameter Reference
- Follow the link for detailed information about the JumpHost element and its parameters.
