Problems with CA

[Florian Feldbauer <florian@ep1.ruhr-uni-bochum.de>]

Hey all,

I have observed some problems with channel access in our lab.
We have a PC with three network interfaces.
On is connected to the network of our institute (->WAN)
the other two are used for local sub nets with its own DNS/DHCP...
The used OS on this PC is Fedora 20.

On one of these local sub nets I have a running EPICS IOC.
When using caget on the PC I always get a timeout error.
Only when I specify the environment variables:
    setenv EPICS_CA_AUTO_ADDR_LIST no
    setenv EPICS_CA_ADDR_LIST 192.168.1.6
caget works.

The IP addresses for the local subnet are dynamically assigned,
and I don't want to look up each time, which addresses are used....
Also I don't want to put all 256 possible addresses in the 
EPICS_CA_ADDR_LIST.

Is there a way to specify a subnet as address lsit for CA?
Or is it possible to bind all request (from Clients as well as from 
Servers) on the machine
to one specific interface?

Best regards,
Florian
