The hosts file can be used by the machine for it to work out what names and IP addresses are associated with each other. It has no bearing on what outside devices know of the machine. e.g. If the machine is 192.168.1.10 it can look in the hosts file for a line with that IP address, and see what names are associated with it, and presume that it's hostname is the first one listed there. Each interface has its own IP address, and you can associate a hostname with it, as well (i.e. a machine with several interfaces will have several *different* addresses). For communication beyond the machine, the machine needs to refer to itself in the same manner as other external machines are going to refer to it. e.g. If they expect it to be fileserver.example.com then the machine should be configured to be fileserver.example.com on the interface that it's using. > I set the external hostname with the gui app (system - admin - network).

(Btw, 1 of my linux units has a static lan IP - for SSH.) Most modem/routers will only have names in their internal table that belong to machines that it doled out an IP address to using DHCP, or that you configured into its DHCP server. Anything done in another way, it won't have any details about it. It depends on DHCP configuration as to whether names are sent over it, as well as IP addresses. -- (This box runs FC6, my others run FC4 & FC5, in case that's important to the thread.) Don't send private replies to my address, the mailbox is ignored. I read messages from the public lists.
