The dhcp-host option has a complex syntax, and the man page doesn't cover all the rules.
One aspect not mentioned is that the order of the arguments don't have to match what it is specified. The man page indicates: --dhcp-host=[<hwaddr>][,id:<client_id>|*][,set:<tag>][,<ipaddr>][,<hostname>][,<lease_time>][,ignore] and yet it show the example: --dhcp-host=lap,192.168.0.199 where hostname appears *before* IP address. Can any argument appear in any oder? If not, what are the rules? Generally, some of these arguments are used by Dnsmasq to identify the client making the request to see if it matches this static rule, while other arguments are used to define the static entry. The behavior of dhcp-host may be clearer if you identified which arguments fall into which of those groups. Some rather useful behaviors, such as being able to assign a host name to a MAC address, without assigning a static IP, are not covered by the man page. There should be an expanded collection of examples that cover things like this. There should be a sentence or two describing each of these options (for example, the format of lease_time is never defined, other than mentioning the special cases of 'infinite 'and 'ignore.' This would also be the place specify default values if the argument is omitted. > The special option id:* means "ignore any client-id and use MAC > addresses only." This is useful when a client presents a client-id > sometimes but not others. How is that different from specifying a mac address and no client-id? -Tom -- Tom Metro Venture Logic, Newton, MA, USA "Enterprise solutions through open source."
