Thanks to the help received here I'm making, (I think), good progress with getting z/tpf under z/vm talking to the outside world.
I've got the virtual nics and the guest lan defined, and according to the traces the tcpip stack appears to correctly route incoming pings to the lan, though there's no stack there yet to respond to them. I'm now enabling OSAE support on z/tpf and one of the mandatory parameters is the osa port name: "PORT-osaport specifies the name of the port on the OSA-Express card, where osaport is a 3- to 8-character alphanumeric port name. The name of the port must be the same for all hosts that have connections to the same OSA-Express card. Each network port defined on a multiport OSA-Express adapter must have a unique port name." I don't appear to be able to specify this on the DEFINE NIC or DEFINE LAN commands. Anyone know where I specify this, or if it just defaults to some standard name? Thanks, ian ... Ian S.
