Re: I have a question about using muti IOC

[Ralph Lange <Ralph.Lange@bessy.de>]

Am I confusing this with multiple CA Gateways on one Linux box? Stupid 
me. But it would be nice, wouldn't it?!
Dammit. I have to think...

Well ... actually we're using multiple VMware virtual machines (probably 
linked clones), which have one IP address each and run one softIOC each. 
That's the layer in-between that I was missing.

I'm sorry.
