In the above mentioned URL you state that: If your system is the only system (or the nameservers handle all name resolution) a single line is sufficient: Code listing 19: /etc/hosts for lonely or fully integrated PCs 127.0.0.1 localhost tux Here tux is the name of your computer. But if you follow this advice you get the following: # cat /etc/hostname lilith # cat /etc/dnsdomainname mydomain # cat /etc/hosts 127.0.0.1 localhost lilith # hostname lilith # hostname -f localhost lilith root # dnsdomainname The last two results are not wanted. Compare the following: # cat /etc/hosts 127.0.0.1 localhost # hostname lilith # hostname -f lilith.mydomain # dnsdomainname mydomain So, please change the recommendation to read only: 127.0.0.1 localhost #no hostname here; I sometimes read aliases like localhost.mydomain 192.68.0.1 tux #in case of no DNS available Reproducible: Always Steps to Reproduce: 1. Read the instructions in the handbook 2. Adopt the settings as described 3. use hostname -f and dnsdomainname Actual Results:
Updated; thanks!
