question on ad-hoc n/ws


hey all.
i have a doubt (and i cant clear it up myself right now, as i only have 1 card on me).
its how ad-hoc connections work. when a cell is formed by one machine, and another one joins that particular cell, does it get the ip addr thro dhcp, or is it assigned one by the machine which first formed the cell?

so, if i want to connnect to an ad-hoc n/w, after specifying the cell's essid, would i have to get an ip addr for my machine via dhcp, or will i have gotten one when i give the cell essid thro iwconfig?

thanks.

You are talking about two different things here (or at least two different network layers).

Ad-hoc network is like you have a network hub connected to your computer and you are going to to around and connect cables to everyone elses computers in range that has the same SSID that you have. (This differs from the "managed access point" network type that is like having a building wired with jacks so that you can plug into any one of them and connect to the entire network in the building by just talking through that one connection) This act alone makes a physical connection only, but has nothing to do with talking TCP/IP.

Your TCP/IP parameters will only get autoconfigured via DHCP if you have a DCHP server somewhere on your network. Otherwise you'll have to manually configure you computer with IP address information that is compatible with the network that you are attempting to connect to.

------------

That said, if you have either some kind of wireless access point / router or Windows machine with a functioning ICS service running or a Linux machine with dhcpd running, then you probably have a DHCP server.
