Whoops sorry about that Alan. I want to make sure I keep those demerits to a 
minimum. ☺

 

 

Thanks for the information! 

 

Thank You,

(You asked a network connectivity question without providing a description 

of the network.  Two demerits.)

 

Watch out for VIPAs.  Using NETSTAT command or CHKIPADR exit, discover the 

IP address of z/OS during a successful FTP.  Is that the same IP you use 

when originating from VM?

 

If you suspect a routing problem, use traceroute on both z/OS and z/VM 

(TRACERTE) to see what's happening.
