/*
* This protocol definition file describes a file transfer
* system used to very quickly move NIS maps from one host to
* another. This is similar to what Sun does with their ypxfrd
* protocol, but it must be stressed that this protocol is _NOT_
* compatible with Sun's. There are a couple of reasons for this:
*
* 1) Sun's protocol is proprietary. The protocol definition is
* not freely available in any of the SunRPC source distributions,
* even though the NIS v2 protocol is.
*
* 2) The idea here is to transfer entire raw files rather than
* sending just the records. Sun uses ndbm for its NIS map files,
* while FreeBSD uses Berkeley DB. Both are hash databases, but the
* formats are incompatible, making it impossible for them to
* use each others' files. Even if FreeBSD adopted ndbm for its
* database format, FreeBSD/i386 is a little-endian OS and
* SunOS/SPARC is big-endian; ndbm is byte-order sensitive and
* not very smart about it, which means an attempt to read a
* database on a little-endian box that was created on a big-endian
* box (or vice-versa) can cause the ndbm code to eat itself.
* Luckily, Berkeley DB is able to deal with this situation in
* a more graceful manner.
*
* While the protocol is incompatible, the idea is the same: we just open
* up a TCP pipe to the client and transfer the raw map database
* from the master server to the slave. This is many times faster than
* the standard yppush/ypxfr transfer method since it saves us from
* having to recreate the map databases via the DB library each time.
* For example: creating a passwd database with 30,000 entries with yp_mkdb
* can take a couple of minutes, but to just copy the file takes only a few
* seconds.
