JCL-Specific Transparent FTP Tunneling

In this example Transparent FTP tunneling is configured per FTP JCL job using a SYSFTPD DD statement.

Do the following steps:

  1. Copy the /etc/ssh2/ssh-socks-proxy-config-example.xml configuration file to /etc/ssh2/ssh-socks-proxy-config.xml.
  2. Start the SOCKS Proxy if it is not already running.
  3. Create a new FTP configuration file EXAMPLE.SSHFTP.FTPDATA with the following contents:
    SOCKSCONFIGFILE  EXAMPLE.JCL.SOCKS.CONF
    FWFRIENDLY       TRUE
    
  4. Create a new socks configuration dataset EXAMPLE.JCL.SOCKS.CONF with the following contents:
    sockd @=127.0.0.1 0.0.0.0 0.0.0.0
    
  5. Modify your existing FTP JCL to use SOCKS by adding a SYSFTPD DD statement, for example:
    //FTP       EXEC PGM=FTP,PARM='company.example.com (EXIT=8'
    //SYSPRINT  DD  SYSOUT=*
    //SYSFTPD   DD  DSN=EXAMPLE.SSHFTP.FTPDATA,DISP=SHR
    //SYSIN     DD  *
    userid   passwd
    ascii
    get test.file 'USERID.FTP.TEST'
    quit
    /*
