I am trying to converse with an IOC (MVME2307) that is located on a different subnet from my solaris machine running my tcl guis, is there a way in my startup script I can add a 2 way route? I am running epics 3.13.1 The vxWorks OS will need to have a route to the other subnet - either a default route or one specific to the subnet address or even the specific host (from a security point of view the fewer addresses the IOC is able to route packets to, the less chance there is of someone being able to do things to the IOC that they're not supposed to, which is why we don't give our IOCs a route to their subnet's default gateway). Look up routeAdd() and routeShow() in the vxWorks reference manual for details. Once your IOC can route IP packets to the other subnet (test that using ping from Solaris), you need to add the name or IP address of the IOC (or the address of its subnet) to the environment variable EPICS_CA_ADDR_LIST before starting your GUI tools. Your CA clients will not automatically reconnect if the IOC gets turned off for more than about 8 minutes; you will probably have to restart them in that event. - Andrew -- Podiabombastic: The tendency to shoot oneself in the foot.
