I have two virtually identical systems, B10 and B11. One is a copy of the other apart from names and network addresses. On B10, "hostname -f" produces the hostname without the domain name, i.e. only "b10". On B11, "hostname -f" produces the hostname with the domain name, i.e. "b11.example.com". I have another few Bxx systems, all virtually identical copies of the same origin - none of them have a problem with "hostname -f". I suspect a DNS issue, but I can't put my finger on it. Any suggestions? -- Per Jessen, Zürich (5.9°C) http://www.hostsuisse.com/ - virtual servers, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

It resolves host name using gethostbyname(). It may be DNS or local hosts depending on nsswitch configuration. Отправлено с iPhone

Thanks, that helped me find it - wrong entry in /etc/hosts. Always nice with some extra pairs of eyes! -- Per Jessen, Zürich (6.2°C) http://www.dns24.ch/ - your free DNS host, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Which openSUSE? What do /etc/HOSTNAME and/or /etc/hostname actually contain? What's in /etc/hosts? What's in /etc/resolv.conf? Maybe https://bugzilla.opensuse.org/show_bug.cgi?id=872264 contains a clue if you need more, but the hostname man page suggests to me /etc/hosts on b10 needs fixing. -- "The wise are known for their understanding, and pleasant words are persuasive."

Yup, that was it. A false entry for 'b10' in /etc/hosts. -- Per Jessen, Zürich (6.2°C) http://www.hostsuisse.com/ - virtual servers, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

That's weird. On my 13.1 system, there is an /etc/HOSTNAME but no /etc/hostname (!). /etc/HOSTNAME is owned by the netcfg.noarch RPM on my system.

I stand corrected. It is indeed /etc/HOSTNAME that exists and is owned by netcfg. On Tw netcfg owns both :) -- (paka)Patrick Shanahan Plainfield, Indiana, USA @ptilopteri http://en.opensuse.org openSUSE Community Member facebook/ptilopteri http://wahoo.no-ip.org Photo Album: http://wahoo.no-ip.org/gallery2 Registered Linux User #207535 @ http://linuxcounter.net -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Not strange at all. Other linuxes hage "hostname", but SUSE* had HOSTNAME since ever, probably. Recently openSUSE has added "hostname", but the old file has not been removed because it would break applications expecting it. One is a symlink to the other. In 13.1 you need do nothing about it. - -- Cheers / Saludos, Carlos E. R.
