My next guess is that there may be a firewall running on your system. Is iptables running?
That is a common cause of the symptoms you are seeing.

They were not set. I vaguely recall having to use them for some special
case in the past, but generally have not, including on dual-NIC systems.
In that case, there was no IOC on the host, rather all were on one of the
two networks.
I have now tried
setenv EPICS_CA_AUTO_ADDR_LIST NO
with either
setenv EPICS_CA_ADDR_LIST "172.18.0.255"
or
setenv EPICS_CA_ADDR_LIST "18.229.255.255"
and caget still just times out. I made sure to kill caRepeater in case its
environment matters.
Also, can you explain what this socket is for ?
epicsdev 10u IPv4 136864 0t0 UDP asym.mit.edu:33586->172.18.0.255:ca-2
For completeness, ifconfig:
eth0 Link encap:Ethernet HWaddr 00:0C:F1:A1:C9:44
inet addr:18.229.0.31 Bcast:18.229.255.255 Mask:255.255.0.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
eth1 Link encap:Ethernet HWaddr 00:A0:C9:CC:F2:FC
inet addr:172.18.0.100 Bcast:172.18.0.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
-------
BTW, the documentation on these variables is rather lacking. The
AppDevGuide refers to the CA Ref Manual, which lists them without really
explaining what they do or how to use them in any detail.
There are more detailed descriptions of a few in base/config/CONFIG_ENV but
why would someone look there, as that file is not intended to be modified ?
The descriptions of the EPICS_CA_* variables there are also not much more
enlightening than the manuals.
