udhcp Server/Client

udhcp Server/Client is an embedded DHCP client and server that can be compiled seperately (19k and 17k respectively), or as one combined binary (29k). The server stores its lease file periodically, or by a signal (for systems with flash memory) in terms of absolute time of lease expiration, or time remaining in a lease (for systems with no clocks). The client calls helper scripts to do the work of configuring the interfaces for more flexibility. udhcp has been included in BusyBox and is no longer maintained as a separate project.

    Release Notes: There is a laundry list of minor bugfixes, including improved lease logic, a fix for occasional incorrect checksum computation on big endian hosts, improved renew behavior, improved signal handling, and a fix to config file parsing. The source now also integrates nicely with busybox; simply drop it into busybox/networking/udhcp whenever you want to sync.

            Release Notes: Install rules were added to the Makefile. Client scripts have been simplified into one script and the redundant info file removed.

Also, the server has been modified to force broadcast to broken clients that request unicast (and can't accept it).
