How do I really change the host name? (11.2)


I suspect that my old host name is still unchanged somewhere in the system after a name change. I think this because the KDE mail client complains that the certificate name doesn’t match my server name. (But the mail client still lets me accept the "wrong-name-certificate, so I can access my imaps mail.)

Where else must I change the host name except:
/etc/hosts w ipv6
Yast//Network Devices//Network Setting?

Is there an rc.conf “kind of file” somewhere that I can’t find?

Thanks in advance.

Kind regards


The server name is inside the certificate used by the IMAP server. Might be simplest to regenerate the certificate.
