Preconditions

  • A YADE Client in the DMZ is used to send files to the internet via a DMZ as a jump server it is necessary to install the YADE client (barebone client without configuration)  on the jump server before starting the file transfer.
  • YADE Client or JobScheduler with YADE JITL Jobs on local site.
  • Configuration file with YADE profiles

Start the File Transfer

The file transfer can be started by using

  1. the local jade4dmz client from command line
  2. the job chain job_chain_jade4dmz.job_chain.xml with orders 
    • order job_chain_jade4dmz,CopyFromInternet.order.xml
    • order job_chain_jade4dmz,CopyToInternet.order.xml

The jade4dmz client is to be started with

 jade4dmz.cmd|sh <configuration file name> <section name> 

Send files to internet via DMZ

 

The process is controlled and checked by a YADE Client in the intranet.
The YADE Client is running the steps described below and as shown in the diagram.

(1) Copy data

As a first step, after checking and creating the temp-folder, the files from the local file system are copied by the YADE Client to the temporary folder in the DMZ.

(2) Start YADE Client on DMZ by SSH

The YADE Client is starting the YADE CLI on the DMZ, using SSH.

(3) Copy data to Internet

The YADE CLI on the DMZ is transferring the files to the destination site in the internet.

(4) Delete data on DMZ

After successful transfer the YADE Client is deleting the files on the DMZ using SSH.

(5) Delete data on local

If configured to do so, the files on the sending site will be deleted by the YADE Client.

Receive files from internet via DMZ

 

1) Copy data

As a first step, after checking and creating the temporary folder, the files from the remote server are copied by the YADE Client to the temporary folder in the DMZ.

(2) Start YADE Client on DMZ by SSH

The YADE Client is starting the YADE CLI on the DMZ, using SSH.

(3) Copy data to Internet

The YADE CLI on the DMZ is transferring the files to the destination site in the internal zone

(4) Delete data on DMZ

After successful transfer the YADE Client is deleting the files on the DMZ using SSH.

(5) Delete data on local

If configured to do so, the files on the receiving site will be deleted by the YADE Client.
