Then I try with 127.255.255.255 and !IT WORKS!I run 2 IOCs without any specific epicsEnv configuration (as some of you recommended), and I open a new console and I run caget, for reach 2 different PVs from the different IOCs. caget does not find any PV. Then I configure the EPICS_CA_ADDRS_LIST=127.0.0.1 or 10.0.2.15, and it only works for the last one executed. Right. Now I check with wirshark and netstat, and I can see that both IOCs are sending beacon messages from 10.0.2.15, so I suppose that if I configure EPICS_CA_ADDR_LIST=10.0.2.255 (this is the broadcast address of that private subnet of my computer) it should work, but it doesn't. the messages are:config 1. CentOS7 (both EPICS 3.14.12.6 and 3.15.5)I have check the following in two different virtual Machines, One Fedora 26, and the other one CentOS7. In both everything works exactly the same.Dear Ralph, Michael, Mark, Kay, Dirk, et al.FIrst of all thank you again for all recommendations. I am going to try to explain which configuration does work and which doesn't.
