* Example mote configuration with one radio interface that uses DHCP
|
|
* to configure its IP stack.
|
|
*
|
|
* The gateway systems must be configured to find what DHCP server to
|
|
* use, this can be done with an extra argument to tunslip, example:
|
|
*
|
|
* sliphost# ./tunslip 172.16.0.1 255.255.0.0 193.10.66.195
|
|
*
|
|
*
|
|
* This kernel has no application code but new modules can be uploaded
|
|
* using the codeprop program, example:
|
|
*
|
|
* datan$ ./codeprop 172.16.0.1 loadable_prg.ko
