Logcheck Meldungen

[Klaus Schuehler <kschuehler@schuehler.com>]

Hallo,

ich bekomme seit neuestem diese Meldungen von Logcheck.


Cron <logcheck@zauberberg>    if [ -x /usr/sbin/logcheck ]; then nice -n10 /usr/sbin/logcheck; fi
hostname: Unknown host

Der Hostname wurde aber nicht geändert. Eine entfernen mit purge und
anschl. Neuinstall brachte keine Änderung.

Dann die Meldung hier:
