Re: guestlan issues
Hello Mark,Marcy.. list.. Indeed as Marcy stated the problem was related to routing and having both my iucv and qdio interface allocated on the same ip.

Re: guestlan issues
If I remember my guestlan correctly, and looking at Marcy's post, you should not be configuring eth0 for your guestlan, it should be hsi0.

Re: guestlan issues
The hsi interface is for the Hipersockets emulation, eth can be used for QDIO.

Re: guestlan issues
I'm in junction in which I need to take a descsion between qdio to hipersocket.. qdio is leading because I've already implemented a connection and understand the configuration and basics. Is hipersockets much better ?(it sounds way cooler ...) I'm using this lan to optimize communication speed and throughput between a group of computers (typically alot of ddr, OS and package installations ) - It's a test environment. This is a second interface on all of these nodes they have a historic iucv network which I'd rather not touch to maintain a period of backward compatability. So is it worth the effort? regards Lior.
