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. - */ - -#ifndef RPC_HDR -%#ifndef lint -%static const char rcsid[] = -% "$FreeBSD: src/include/rpcsvc/ypxfrd.x,v 1.7 1999/08/27 23:45:13 peter Exp $"; -%#endif /* not lint */ -#endif - -/* XXX cribbed from yp.x */ -const _YPMAXRECORD = 1024; -const _YPMAXDOMAIN = 64; -const _YPMAXMAP = 64; -const _YPMAXPEER = 64; - -/* Suggested default -- not necesarrily the one used. */ -const YPXFRBLOCK = 32767; - -/* - * Possible return codes from the remote server. - */ -enum xfrstat { - XFR_REQUEST_OK = 1, /* Transfer request granted */ - XFR_DENIED = 2, /* Transfer request denied */ - XFR_NOFILE = 3, /* Requested map file doesn't exist */ - XFR_ACCESS = 4, /* File exists, but I couldn't access it */ - XFR_BADDB = 5, /* File is not a hash database */ - XFR_READ_OK = 6, /* Block read successfully */ - XFR_READ_ERR = 7, /* Read error during transfer */ - XFR_DONE = 8, /* Transfer completed */ - XFR_DB_ENDIAN_MISMATCH = 9, /* Database byte order mismatch */ - XFR_DB_TYPE_MISMATCH = 10 /* Database type mismatch */ -}; - -/* - * Database type specifications.
