Hello,
I am a complete beginner to omniORB. I have configured
nameService to be running on the FreeBSD server
with "InitRef = NameService=corbaname::m.saper.info".
m.saper.info has an A DNS record and the AAAA DNS record
"2a01:4f8:a0:7383::".
"nameclt list" failed to connect though:

as it turns out, omni::LibcWrapper::isip6addr("2a01:4f8:a0:7383::") was returning false.
The following patch seems to fix this:

- if (seen_blank) {
- if (colons == 2)
- return 1;
- else
- return 0;
- }
return 1;
}
I am not sure if the "colons < 1" condition is proper, since
then isip6addr("2a01") is false, but isip6addr("2a01:")
is true. With "colons < 2" isip6addr("2a01:") is false,
but isip6addr("2a01:a:") is true.
There are no unit tests for this function so I am not sure
if there are no regressions there.
I also wonder if this function shouldn't accept zone indexed
addresses (fe80::3%iface) as well.
All the best,
Marcin Cieślak
