Modifying hostname doesn't update /etc/hosts
Last modified: 2007-11-30 17:07:01 EST
From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322) Description of problem: When you go to the DNS tab and modify the hostname field, then go File->Save and restart network services the /etc/hosts file is not updated to reflect the fact that 127.0.0.1 is the new hostname. Version-Release number of selected component (if applicable): 1.2.58 How reproducible: Always Steps to Reproduce: 1. During install hostname set to "hostone" 2. After install use GUI to set hostname to "hosttwo" Actual Results: /etc/hosts still says "hostone" is the localhost instead of "hosttwo" Expected Results: /etc/hosts should say "hosttwo" is the localhost, for 127.0.0.1 Additional info:
right, /etc/hosts should be modified... but /etc/sysconfig/network is modified. In real networks the IP address should not be 127.0.0.1 anyway...
In Fedora Core 2, both /etc/sysconfig/network and /etc/hosts are not updated by system-config-network when trying to change hostname.
