Dear All After today's updates, the command line is [psmith@unknown-00-14-85-38-2c-93 ~]$ and before it was [psmith@mypc ~]$ How can I replace unknown-00-14-85-38-2c-93 with mypc?
Looks like your ISP or local DHCP server is setting your hostname. By default dhclient asks to be assigned a new hostname.
man dhclient.confshows you can create an /etc/dhclient.conf with a "request" line that excludes host-name, that should stop it getting set.
