The HiperSocket is working just fine, as demonstrated by your TCPDUMP. It's a routing problem. It's ALWAYS a routing problem. Look at the Linux guest's routing table to see where that packet is going. Ensure that z/OS and the Linux guest are using the same subnet mask and MTU size on their HiperSocket connection. When in doubt, draw your networks on a piece of paper and label them with IP addresses and subnet masks. It will quickly become apparent if you've got your virtual wires crossed.
