The "Operation not permitted" error indicates a firewall rule which is
blocking the multicast traffic to the mcast group used in this test
scenario (239.239.239.18).

I can reproduce the test failure by inserting the following rule on my
system:

~$ sudo iptables -I OUTPUT --dst 239.239.239.18 -j DROP

What is the firewall policy for build hosts? As it seems firewall rules
are not identical since this test passes on other build hosts without
problems.

Is there a multicast group we could use which is allowed on all build
hosts for test purposes? The other solution would be to disable the
CORBA_MIOP test ...

Note: This test *does not* need network/internet access.
