Running as root: # hostname acme.dev.nul (assuming you wish to name the host: 'acme.dev.nul'), and adding or editting the "HOSTNAME=" line in: # /etc/sysconfig/network appropriately will do the trick. Some applications also want to be able to do a lookup of hostname to IP, and for that purpose, editting /etc/hosts is often done. Another and better solution to that second question is to place the server in an environment with a working forward and reverse DNS and letting the initscripts manage the matter. We just answer the question about changing a server's name here. See also the file documentation concerning the initscripts, which in the first instance handle the setting of the server name based on the values found in /etc/sysconfig/network or /etc/sysconfig/network-scripts/ifcfg-ethX: # rpm -ql initscripts | grep doc | |
