Leonard,

It would appear that ioctl(SIOCGIFCONF) returns errno six on your 
system. This indicates "No such device or address". There are some 
subtle difference in this io control between the IP kernels in Tornado 
I and in Tornado II, but the call should be initially successful on
both OS. So I am confused. What do you see when you type ifShow on 
your system? Is there any possibility that EPICS was built against
Tornado II header files and then loaded into a Tornado I system?
I have not tried this. Perhaps there would be undefined symbols.

A quick look at the source does not indicate why your shell is hanging. 
The "exit" in the output below is probably a clue, but I don't see any
code that prints this message in R3.13. If you typed "exit" at a shell 
prompt a hung ( non-existent ) shell would certainly result.

Otherwise to help us track down the hang please use "sp iocInit" instead 
of "iocInit", and then use tt <task id> on the resulting task to
see where it is hanging. Usually the first task spawned with "sp" has 
name t1 and so you can alternatively type "tt t1". Please e-mail the output
from tt.

Thanks

Jeff
