Yes, your network diagram is messed up. Your picture is Linux [Guest LAN] TCPIP [HiperSockets] MVS TCPIP is connected to two HiperSocket networks: one real (to MVS) and one virtual (to Linux). So TCPIP will need two HiperSocket interfaces, each with it's own IP address in each of the two networks. You have the real one (5.1.1.1), but you are missing 5.1.2.x, which is what Linux would use as its default gateway, not 5.1.1.1. You can't ping 5.1.1.1 from Linux since it isn't directly attached to the Linux guest and you don't have a reachable gateway. BTW, you can use the ifconfig command on VM to get a much better display of the VM config. As an aside, I don't recommend the use of HiperSocket Guest LANs unless it is for testing purposes. Instead, use a virtual switch without an OSA. The access controls on VSWITCHes are far better than it is for Guest LANs.
