New submission from Daniel Frnake <dfra...@wellohorld.com>: On Linux and presumably on other POSIX-like systems, socket.getfqdn() doesn't work if a system resolves its own FQDN using DNS rather than /etc/hosts.
My system's FQDN is 'fugue.tank.wellohorld.com'. My /etc/hosts is empty except for loopback entries, and /etc/resolv.conf contains the line 'domain tank.wellohorld.com'. This is sufficient for 'hostname -f' to do the Right Thing, but socket.getfqdn() simply returns 'fugue': dfra...@fugue:~/Python-2.6.1$ hostname fugue dfra...@fugue:~/Python-2.6.1$ hostname -f fugue.tank.wellohorld.com dfra...@fugue:~/Python-2.6.1$ ./python Python 2.6.1 (r261:67515, Jan 19 2009, 13:56:59) [GCC 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import socket >>> socket.getfqdn() 'fugue' >>> dfra...@fugue:~/Python-2.6.1$ echo -e '$a\n172.17.0.120 fugue.tank.wellohorld.com fugue\n.\nwq' | sudo ed /etc/hosts 305 350 dfra...@fugue:~/Python-2.6.1$ ./python Python 2.6.1 (r261:67515, Jan 19 2009, 13:56:59) [GCC 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import socket >>> socket.getfqdn() 'fugue.tank.wellohorld.com' >>> dfra...@fugue:~/Python-2.6.1$ ---------- components: Library (Lib) messages: 80216 nosy: dfranke severity: normal status: open title: socket.getfqdn() doesn't cope properly with purely DNS-based setups type: behavior versions: Python 2.6 _______________________________________ 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
