Python built on a RHEL, Fedora, or CentOS system gives bad getfqdn() Result

[tolistim]

I received an answer from another user off-forum. He received from Cox the following when he reported this:

"This is expected bahavior[sic]. The Cox Business Online DNS resolvers have NXDOMAIN redirection services that redirect any unknown host to a sponsored search page. You can opt out of this by changing your resolver from .11/.12 to .14."

I did just that, changing my resolv.conf to call .14 for the three servers and the issue is resolved.

Digging into this further, it seems that all of my non-RH systems set the nameserver to 127.0.0.1 and search to build.tolisgroup.com. This results in the proper result in all cases.

This still does not answer the oddity that the RH systems' "hostname --fqdn" and the Python "socket.getfqdn()" return different results.
