Hi all, I change the machine hostname by using follow commands
$ hostname puppet-master.domain.com $ sed -i 's/HOSTNAME=.*/HOSTNAME=puppet-master.domain.com/' /etc/sysconfig/network But when checking it. I got following output $ hostnamepuppet-master.domain.com $ hostname --long puppet-master.domain.com.novalocal $ hostname -A localhost If I add the ip-domain mapping to the /etc/hosts file, it became right. $ echo "10.0.0.10 puppet-master.domain.com puppet-master" >> /etc/hosts $ hostnamepuppet-master.domain.com $ hostname --longpuppet-master.domain.com $ hostname -Apuppet-master.domain.com I want to know why the hosts contents affect the hostname command -- Lei Zhang Blog: http://jeffrey4l.github.com twitter/weibo: @jeffrey4l
