Hello All,

 

I think I am having problems with routing with the epics archiver.  When I have the archiver on a LAN and is on the same subnet as the IOCs being archived it seems to work fine but when I have archiver on a different subnet it doesn’t seem to want to archive those PVs anymore. For example

 

Same Subnet, CS Studio Picks up PVs, caget works, archiver works

192.168.10.20 Epics Archiver Computer

192.168.10.21 IOC running

 

 

Different Subnet, CS Studio picks up PVs, caget works, Archiver will not archive PVs

192.168.10.20 Epics Archiver Computer

192.168.11.21 IOC running

 

 

I have both the epics variables set in my env variables, in archappl.conf (archiver file), in settings.ini (cs studio file).  It seems odd that caget, cs studio work fine but the archiver is having an issue seeing the IOC that is on the other subnet.  Is there another environment variable I am missing that needs to be set when services are on different subnets like this?  I checked firewalls/ports/traffic it seems like the same requests are being made by cs studio/caget as the archiver but the archiver ones don’t seem to go anywhere (just keep trying to retransmit).
