important, it's always good to be frugal.

Specifics:
|
|
||||||
|
|
||||||
Implementation language will be C. C is universally available, very
|
|
||||||
predictable, and well accepted. dhcp clients don't have to deal with
|
|
||||||
complicated data structures or extensively with strings, so C's
|
|
||||||
largest weaknesses should not be highly apparent. On the other hand,
|
|
||||||
dhcp clients must extensively deal with the OS in a low-level fashion.
|
|
||||||
C's strongest points will therefore be used.
|
|
||||||
|
|
||||||
More practically, a program written in a compiled language other than
|
|
||||||
C will be poorly accepted by the average user. Since widespread use
|
|
||||||
is an eventual goal of ndhc, this point is very eloquent.
|
|
||||||
|
|
||||||
For now, I'm taking advantage of the existing udhcpc. With minor
|
|
||||||
modifications, it will serve quite well as the dhcp client daemon. It
|
|
||||||
is then only necessary for me to write a client request translator
|
|
||||||
and a interface change daemon. The result should be a highly modular
|
|
||||||
solution.
|
|
||||||
|
|
||||||
I'm developing on a Linux-based platform. ndhc will first be designed
|
|
||||||
to work properly on a Linux-based system. I will then make certain
|
|
||||||
that ndhc works well on a RSBAC-enabled Linux system. Afterwards, I
|
|
||||||
_may_ spend some effort porting ndhc to FreeBSD (but don't count on it). I
|
|
||||||
have no personal interest in other platforms.
