Unfortunately I am not entirely sure who is "correct" here, as I don't know the intent of socket.getfqdn(). In my case, kernelhostname is set to 'pclin281' e.g. without the dots. I believe this to be correct, but I know that this is already "controversial" as in there exists software that expects an FQDN there, and internet folklore is split about 50/50 about this necessity. Then, apparently, there is confusion about AI_CANONNAME and what it actually should do. glibc upstream does address lookups but Fedora patches this out. See this recent glibc bug for more pointers: http://sourceware.org/bugzilla/show_bug.cgi?id=15218 As mentioned in that bug, a lot of software runs on Fedora and works using that definition of AI_CANONNAME. However, switching Lib/socket.py / getfqdn from gethostbyaddr to getaddrinfo might have more implications than just fixing this case. I can try to write a patch, but is this the right direction? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue5004> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
