Dual DHCP DNS Server is a DHCP server combined with a caching DNS server that is sensitive to the names that were allocated by the DHCP server. It has built in dynamic updates, and also supports BOOTP PXE network booting and client specific options. It is self-configuring, doesn't require the creation of zone files, and uses little memory and CPU time. Either one of the two services can be turned off.
TFTP Server is a multi-threaded TFTP server, allowing any number of clients to connect simultaneously. It supports tsize, blksize, and interval options, PXE boot, and can be run standalone or as a daemon. Port ranges can be specified to work across firewalls. There is also a single port version, for situations where additional ports cannot be opened.
