This is seldom necessary - an adjusted /etc/hosts should do. We also use the "host_aliases" file, but there was no need to set up a DNS server for it to work. On the master itself it shouldn't be a problem at all, only for the nodes in case the /etc/hosts isn't copied and also NIS doesn't resolve the entries. Did you specify the FQDN in the "host_aliases" file? -- Reuti > Dan > > On Wed, 2014-01-01 at 01:08 +0100, Reuti wrote: >> Hi, >> >> Am 31.12.2013 um 21:02 schrieb Daniel R.
