Subject:	problem with gateway and softIoc running on same server

Hi,

I want a gateway to publish PVs from 192.168.134.51:8064 which is on a private network connected to 192.171.95.112 (where a softIoc is already running) because I can’t access this private

I have the situation where I have a solaris-8 server (192.171.95.112) with two network cards. One goes to our observatory network and the other goes to a private network running a windows based softIoc (192.168.134.51). Now I need access to the PVs of the widows softIoc from other IPs on the observatory network.

I can successfully get the gateway to publish the windows softIoc PVs without any problems. However, I have a solaris softIoc running on the same server as the gateway and this is where I’m having problems. I’ve tried using different EPICS_CA_SERVER_PORTS for both IOCs but no matter what I try I can’t get the gateway to see the solaris IOC on the same IP. If I manually set my EPICS_CA_SERVER_PORT at the command line then issue a caget, it successfully returns the PV value but it reports that there’s multiple instances of the PV.

My question is: can a gateway co-exist with a softIoc in the same ip address?

If so, what do I need to do to make it happen? Using different EPICS_CA_SERVER_PORTs doesn’t seem to be it. Is this related to the fact that I can’t run multiple softIocs on the same server unless I change port numbers? In which case I’d want a gateway to interface to them as well.

Here’s my startup command run on the solaris server (128.171.95.112):

/usr/local/epics/r3.14.9/extensions/bin/solaris-sparc-gnu/gateway -debug 1 -pvlist k1lmct.pvlist -access GATEWAY.access -home $HOME -log k1lmct.log -sip "128.171.95.112" -sport 5064 -cip "192.171.95.112:8164 192.168.134.51:8064" -prefix k1:lmct:gateway&

Here’s the start of the debug output log:

PV Gateway Version 2.0.3.0 [Feb 20 2008 16:27:23]

EPICS 3.14.9 PID=13539

Thank you in advance!
