USING RPC/XDR ON RTEMS
======================
For the most part, programmers using RPC/XDR routines on RTEMS
can proceed as if they were to be using a POSIX/UNIX system.
The only significant changes are those to start the portmapper
and to allow use of RPC/XDR by multiple threads.
Starting the portmapper
=======================
The SUN portmapper program has been modified to run as an RTEMS
task. Applications which need the portmapper can start this
task by calling:
int rtems_rpc_start_portmapper (int priority);
The return value is an RTEMS status code.
Multi-threaded operation
========================
The RPC/XDR package has been modified to allow for multiple RTEMS
tasks to use RPC/XDR routines. If more than one task is to call
an RPC/XDR routine, the additional tasks must call:
int rtems_rpc_task_init(void);
before calling any RPC/XDR routines. For example, the portmapper
calls this routine since the portmapper uses RPC/XDR routines in
a separate thread.
The return value is an RTEMS status code.
Porting Notes
=============
Most of the FreeBSD rpc library ports to RTEMS with little
or no modification beyond that required to provide for operation
in a multitasking environment. Multitasking operation was
provided by moving all `static persistence' variables into
a single structure and using an RTEMS task variable to point
to that structure.
Some of the library, however, has not made it into the RTEMS
implementation. FreeBSD source files which have been left out include:
- Files which provide RPC to the AF_UNIX address family:
clnt_unix.c
svc_unix.c
An `ifndef __rtems__' was added to clnt_generic.c because clnt_unix.c
was omitted.
- Files which need NIS:
auth_time.c
- Files which provide DES authentication:
auth_des.c
authdes_prot.c
crypt_client.c
des_crypt.c
des_soft.c
getpublickey.c
key_call.c
key_prot_xdr.c
svc_auth_des.c
The FreeBSD xdr source compiles and runs on RTEMS without modification.

* This protocol definition exists because of the U.S. government and

* States to other countries (even though the code already exists

* Secure RPC work. The normal way around this is to break the DES
* code out into a shared library; we can then provide a dummy lib
* in the base OS and provide the real lib in the secure dist, which
* the user can install later. But we need Secure RPC for NIS+, and
* there are several system programs that use NIS+ which are statically
* linked. We would have to provide replacements for these programs
* in the secure dist, but there are a lot, and this is a pain. The
* shared lib trick won't work for these programs, and we can't change
* them once they're compiled.
*
* One solution for this problem is to do the DES encryption as a system
* call; no programs need to be changed and we can even supply the DES
* support as an LKM. But this bloats the kernel. Maybe if we have
* Secure NFS one day this will be worth it, but for now we should keep
* this mess in user space.
*
* So we have this second solution: we provide a server that does the
* DES encryption for us. In this case, the server is keyserv (we need
* it to make Secure RPC work anyway) and we use this protocol to ship
* the data back and forth between keyserv and the application.

* integer size, followed by the useful data. The answer is, when the
* server doesn't recognize the type returned it treats it as opaque data.
* And the definition for opaque data is {int size; char *data;}. In this
* way, servers and utility routines that do not understand a given type
* may still pass it around. One has to be careful in setting
* this variable accurately, it must take into account such things as
* XDR padding of structures etc. The best way to set it is to note one's
* position in the XDR encoding stream, encode the structure, look at the

% * Protocol for the local binder service, or pmap.
% *
% * Copyright (C) 1984, Sun Microsystems, Inc.
% *
% * The following procedures are supported by the protocol:
% *
% * PMAPPROC_NULL() returns ()
% * takes nothing, returns nothing
% *
% * PMAPPROC_SET(struct pmap) returns (bool_t)
% * TRUE is success, FALSE is failure. Registers the tuple
% * [prog, vers, prot, port].
% *
% * PMAPPROC_UNSET(struct pmap) returns (bool_t)
% * TRUE is success, FALSE is failure. Un-registers pair
% * [prog, vers]. prot and port are ignored.
% *
% * PMAPPROC_GETPORT(struct pmap) returns (long unsigned).
% * 0 is failure. Otherwise returns the port number where the pair
% * [prog, vers] is registered. It may lie!
% *
% * PMAPPROC_DUMP() RETURNS (struct pmaplist_ptr)
% *
% * PMAPPROC_CALLIT(unsigned, unsigned, unsigned, string<>)
% * RETURNS (port, string<>);
% * usage: encapsulatedresults = PMAPPROC_CALLIT(prog, vers, proc,
% * encapsulatedargs);
% * Calls the procedure on the local machine. If it is not registered,
% * this procedure is quite; ie it does not return error information!!!
% * This procedure only is supported on rpc/udp and calls via
% * rpc/udp. This routine only passes null authentication parameters.
% * This file has no interface to xdr routines for PMAPPROC_CALLIT.
% *
% * The service supports remote procedure calls on udp/ip or tcp/ip socket 111.

/*
* 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.

RPCSRC 4.0 7/11/89
This distribution contains Sun Microsystem's implementation of the
RPC and XDR protocols and is compatible with 4.2BSD and 4.3BSD. Also
included is complete documentation, utilities, RPC service
specification files, and demonstration services in the format used by
the RPC protocol compiler (rpcgen). See WHAT'S NEW below for
details.
NOTE ABOUT SECURE RPC:
This release of RPCSRC contains most of the code needed to implement
Secure RPC (see "DES Authentication" in the RPC Protocol Specification,
doc/rpc.rfc.ms). Due to legal considerations, we are unable to
distribute an implementation of DES, the Data Encryption Standard, which
Secure RPC requires. For this reason, all of the files, documentation, and
programs associated with Secure RPC have been placed into a separate
directory, secure_rpc. The RPC library contained in the main body of this
release *DOES NOT* support Secure RPC. See secure_rpc/README for more
details. (A DES library was posted in Volume 18 of comp.sources.unix.)
If you wish to report bugs found in this release, send mail to:
Portable ONC/NFS
Sun Microsystems, Inc

or send Email to nfsnet@sun.com (the Internet) or sun!nfsnet (Usenet).
ROADMAP
The directory hierarchy is as follows:
demo/ Various demonstration services
demo/dir Remote directory lister
demo/msg Remote console message delivery service
demo/sort Remote sort service
doc/ Documentation for RPC, XDR and NFS in "-ms" format.
etc/ Utilities (rpcinfo and portmap). portmap must be
started by root before any other RPC network services are
used. SEE BELOW FOR BUGFIX TO 4.3BSD COMPILER.
man/ Manual pages for RPC library, rpcgen, and utilities.
rpc/ The RPC and XDR library. SEE BELOW
FOR BUGFIX TO 4.2BSD COMPILER.
rpcgen/ The RPC Language compiler (for .x files)
rpcsvc/ Service definition files for various services and the
server and client code for the Remote Status service.
secure_rpc/ The files in this directory are used to build a version of
the RPC library with DES Authentication. See the README
file in that directory for more details.
BUILD INSTRUCTIONS
Makefiles can be found in all directories except for man. The
Makefile in the top directory will cause these others to be invoked
(except for in the doc, man and demo directories), in turn building the
entire release.
WARNING! THE DEFAULT INSTALLATION PROCEDURES WILL INSTALL FILES
IN /usr/include, /usr/lib, /usr/bin and /etc.
The master RPC include file, rpc/rpc.h, is used by all programs and
routines that use RPC. It includes other RPC and system include files
needed by the RPC system. PLEASE NOTE: If your system has NFS, it
may have been based on Sun's NFS Source. The include files installed
by this package may duplicate include files you will find on your NFS
system. The RPCSRC 4.0 include files are upwardly compatible to all
NFS Source include files as of the date of this distribution (not
including any new definitions or declarations added by your system
vendor). HOWEVER: Please read the comments towards the end of
rpc/rpc.h regarding rpc/netdb.h. You may need to uncomment the
inclusion of that file if the structures it defines are already
defined by your system's include files.
After making any compiler fixes that are needed (see below), at
the top directory, type:
make install
For all installations, the Makefile macro DESTDIR is prepended to the
installation path. It is defined to be null in the Makefiles, so
installations are relative to root. (You will probably need root
privileges for installing the files under the default path.) To
install the files under some other tree (e.g., /usr/local), use the
command:
make install DESTDIR=/usr/local
This will place the include files in /usr/local/usr/include, the RPC
library in /usr/local/usr/lib, rpcgen in /usr/local/usr/bin, and the
utilities in /usr/local/etc. You'll have to edit the Makefiles or
install the files by hand if you want to do anything other than this
kind of relocation of the installation tree.
The RPC library will be built and installed first. By default it is
installed in /usr/lib as "librpclib.a". The directory
/usr/include/rpc will also be created, and several header files will
be installed there. ALL RPC SERVICES INCLUDE THESE HEADER FILES.
The programs in etc/ link in routines from librpclib.a. If you change
where it is installed, be sure to edit etc/'s Makefile to reflect this.
These programs are installed in /etc. PORTMAP MUST BE RUNNING ON
YOUR SYSTEM BEFORE YOU START ANY OTHER RPC SERVICE.
rpcgen is installed in /usr/bin. This program is required to build
the demonstration services in demo and the rstat client and server in
rpcsvc/.
The rpcsvc/ directory will install its files in the directory
/usr/include/rpcsvc. The Remote Status service (rstat_svc) will be
compiled and installed in /etc. If you wish to make this service
available, you should either start this service when needed or have
it started at boot time by invoking it in your /etc/rc.local script.
(Be sure that portmap is started first!) Sun has modified its
version of inetd to automatically start RPC services. (Use "make
LIB=" when building rstat on a Sun Workstation.) The Remote Status
client (rstat) will be installed in /usr/bin. This program queries
the rstat_svc on a remote host and prints a system status summary
similar to the one printed by "uptime".
The documentation is not built during the "make install" command.
Typing "make" in the doc directory will cause all of the manuals to
be formatted using nroff into a single file. We have had a report
that certain "troff" equivalents have trouble processing the full
manual. If you have trouble, try building the manuals individually
(see the Makefile).
The demonstration services in the demo directory are not built by the
top-level "make install" command. To build these, cd to the demo
directory and enter "make". The three services will be built.
RPCGEN MUST BE INSTALLED in a path that make can find. To run the
services, start the portmap program as root and invoke the service
(you probably will want to put it in the background). rpcinfo can be
used to check that the service succeeded in getting registered with
portmap, and to ping the service (see rpcinfo's man page). You can
then use the corresponding client program to exercise the service.
To build these services on a Sun workstation, you must prevent the
Makefile from trying to link the RPC library (as these routines are
already a part of Sun's libc). Use: "make LIB=".
BUGFIX FOR 4.3BSD COMPILER
The use of a 'void *' declaration for one of the arguments in
the reply_proc() procedure in etc/rpcinfo.c will trigger a bug
in the 4.3BSD compiler. The bug is fixed by the following change to
the compiler file mip/manifest.h:
*** manifest.h.r1.1 Thu Apr 30 13:52:25 1987
--- manifest.h.r1.2 Mon Nov 23 18:58:17 1987
***************
*** 21,27 ****
/*
* Bogus type values
*/
! #define TNULL PTR /* pointer to UNDEF */
#define TVOID FTN /* function returning UNDEF (for void) */
/*
--- 21,27 ----
/*
* Bogus type values
*/
! #define TNULL INCREF(MOETY) /* pointer to MOETY -- impossible type */
#define TVOID FTN /* function returning UNDEF (for void) */
/*
If you cannot fix your compiler, change the declaration in reply_proc()
from 'void *' to 'char *'.
BUGFIX FOR 4.2BSD COMPILER
Unpatched 4.2BSD compilers complain about valid C. You can make old
compilers happy by changing some voids to ints. However, the fix to
the 4.2 VAX compiler is as follows (to mip/trees.c):
*** trees.c.r1.1 Mon May 11 13:47:58 1987
--- trees.c.r1.2 Wed Jul 2 18:28:52 1986
***************

WHAT'S NEW IN THIS RELEASE: RPCSRC 4.0
The previous release was RPCSRC 3.9. As with all previous releases,
this release is based directly on files from Sun Microsystem's
implementation.
Upgrade from RPCSRC 3.9
1) RPCSRC 4.0 upgrades RPCSRC 3.9. Improvements from SunOS 4.0 have
been integrated into this release.
Secure RPC (in the secure_rpc/ directory)
2) DES Authentication routines and programs are provided.
3) A new manual, "Secure NFS" is provided, which describes Secure RPC
and Secure NFS.
4) Skeleton routines and manual pages are provided which describe the
DES encryption procedures required by Secure RPC. HOWEVER, NO DES
ROUTINE IS PROVIDED.
New Functionality
5) rpcinfo can now be used to de-register services from the portmapper
which may have terminated abnormally.
6) A new client, rstat, is provided which queries the rstat_svc and
prints a status line similar to the one displayed by "uptime".

.Dt BINDRESVPORT 3
.Os
.Sh NAME
.Nm bindresvport ,
.Nm bindresvport_sa
.Ndbind a socket to a privileged IP port
.Sh SYNOPSIS
.Fd #include <rpc/rpc.h>
.Ft int
.Fn bindresvport "int sd" "struct sockaddr_in *sin"
.Ft int
.Fn bindresvport_sa "int sd" "struct sockaddr *sa"
.Sh DESCRIPTION
.Fn bindresvport
and
.Fn bindresvport_sa
are used to bind a socket descriptor to a privileged
.Tn IP
port, that is, a
port number in the range 0-1023.
.Pp
Only root can bind to a privileged port; this call will fail for any
other users.
.Pp
When
.Va sin
is not null,
.Va sin->sin_family
must be initialized to the address family of the socket, passed by
.Va sd .
If the value of sin->sin_port is non-zero
.Fn bindresvport
will attempt to use that specific port. If it fails, it chooses another
privileged port automatically.
.Pp
It is legal to pass null pointer to
.Va sin .
In this case, the caller cannot get the port number
.Fn bindresvport
has picked.
.Pp
Function prototype of
.Fn bindresvport
is biased to
.Dv AF_INET
socket.
.Fn bindresvport_sa
acts exactly the same, with more neutral function prototype.
Note that both functions behave exactly the same, and
both support
.Dv AF_INET6
sockets as well as
.Dv AF_INET
sockets.
.Sh RETURN VALUES
.Fn bindresvport
and
.Fn bindresvport_sa
return 0 if they are successful, otherwise \-1 is returned and
.Va errno
set to reflect the cause of the error.
.Sh ERRORS
The
.Fn bindresvport
and
.Fn bindresvport_sa
functions fail if:
.Bl -tag -width Er
.It Bq Er EBADF
.Fa sd
is not a valid descriptor.
.It Bq Er ENOTSOCK
.Fa sd
is not a socket.
.It Bq Er EADDRNOTAVAIL
The specified address is not available from the local machine.
.It Bq Er EADDRINUSE
The specified address is already in use.
.It Bq Er EINVAL
The socket is already bound to an address,
or the socket family and the family of specified address mismatch.
.It Bq Er EACCES
The requested address is protected, and the current user
has inadequate permission to access it.
.It Bq Er EFAULT
The
.Fa name
parameter is not in a valid part of the user
address space.
.It Bq Er ENOBUFS
Insufficient resources were available in the system
to perform the operation.
.It Bq Er EPFNOSUPPORT
The protocol family has not been configured into the
system, no implementation for it exists,
or address family did not match between arguments.

.IX encryption cbc_crypt "" \fLcbc_crypt\fP

.IX encryption des_setparity "" \fLdes_setparity\fP
.IX "des encryption" des_setparity "DES encryption" \fLdes_setparity\fP
.B ecb_crypt(\|)
and
.B cbc_crypt(\|)
implement the
.SM NBS
.SM DES
(Data Encryption Standard).
These routines are faster and more general purpose than
.BR crypt (3).
They also are able to utilize
.SM DES
hardware if it is available.
.B ecb_crypt(\|)
encrypts in
.SM ECB
(Electronic Code Book)
mode, which encrypts blocks of data independently.
.B cbc_crypt(\|)
encrypts in
.SM CBC
(Cipher Block Chaining)
mode, which chains together
successive blocks.
.SM CBC
mode protects against insertions, deletions and
substitutions of blocks.
Also, regularities in the clear text will
not appear in the cipher text.
.LP
Here is how to use these routines. The first parameter,
.IR key ,
is the 8-byte encryption key with parity.
To set the key's parity, which for
.SM DES
is in the low bit of each byte, use
.IR des_setparity .
The second parameter,
.IR data ,
contains the data to be encrypted or decrypted.
The
third parameter,
.IR datalen ,
is the length in bytes of
.IR data ,
which must be a multiple of 8. The fourth parameter,
.IR mode ,
is formed by
.SM OR\s0'ing
together some things. For the encryption direction 'or' in either
.SM DES_ENCRYPT
or
.SM DES_DECRYPT\s0.
For software versus hardware
encryption, 'or' in either
.SM DES_HW
or
.SM DES_SW\s0.
If
.SM DES_HW
is specified, and there is no hardware, then the encryption is performed
in software and the routine returns
.SM DESERR_NOHWDEVICE\s0.
For
.IR cbc_crypt ,
the parameter
.I ivec
is the the 8-byte initialization
vector for the chaining. It is updated to the next initialization
vector upon return.
.LP
.SH "SEE ALSO"
.BR des (1),
.BR crypt (3)
.SH DIAGNOSTICS
.PD 0
.TP 20
.SM DESERR_NONE
No error.
.TP
.SM DESERR_NOHWDEVICE
Encryption succeeded, but done in software instead of the requested hardware.
.TP
.SM DESERR_HWERR
An error occurred in the hardware or driver.
.TP
.SM DESERR_BADPARAM
Bad parameter to routine.
.PD
.LP
Given a result status
.IR stat ,
the macro
.SM DES_FAILED\c
.BR ( stat )
is false only for the first two statuses.
.SH RESTRICTIONS
These routines are not available in RPCSRC 4.0.
This information is provided to describe the DES interface expected by
Secure RPC.

.Sh NAME
.Nm getrpcent ,
.Nm getrpcbyname ,
.Nm getrpcbynumber ,
.Nm endrpcent ,
.Nm setrpcent
.Nd get RPC entry
.Sh SYNOPSIS
.Fd #include <rpc/rpc.h>
.Ft struct rpcent *
.Fn getrpcent void
.Ft struct rpcent *
.Fn getrpcbyname "char *name"
.Ft struct rpcent *
.Fn getrpcbynumber "int number"
.Ft void
.Fn setrpcent "int stayopen"
.Ft void
.Fn endrpcent void
.Sh DESCRIPTION
The
.Fn getrpcent ,
.Fn getrpcbyname ,
and
.Fn getrpcbynumber
functions each return a pointer to an object with the
following structure
containing the broken-out
fields of a line in the rpc program number data base,
.Pa /etc/rpc .
.Bd -literal
struct rpcent {
char *r_name; /* name of server for this rpc program */
char **r_aliases; /* alias list */
long r_number; /* rpc program number */
};
.Ed
.Pp
The members of this structure are:
.Bl -tag -width r_aliasesxxx
.It Fa r_name
The name of the server for this rpc program.
.It Fa r_aliases
A zero terminated list of alternate names for the rpc program.
.It Fa r_number
The rpc program number for this service.
.El
.Pp
The
.Fn getrpcent
function reads the next line of the file, opening the file if necessary.
The
.Nm getrpcent
function opens and rewinds the file. If the
.Fa stayopen
flag is non-zero,
the net data base will not be closed after each call to
.Fn getrpcent
(either directly, or indirectly through one of
the other
.Fn getrpcent
function family.
.Pp
.Fn endrpcent
closes the file.
.Pp
.Fn getrpcbyname
and
.Fn getrpcbynumber
sequentially search from the beginning
of the file until a matching rpc program name or
program number is found, or until end-of-file is encountered.
.Sh FILES
.Bl -tag -width /etc/rpc -compact
.It Pa /etc/rpc
.El
.Sh "SEE ALSO"
.Xr rpc 5 ,
.Xr rpcinfo 8 ,
.Xr ypserv 8
.Sh DIAGNOSTICS
A
.Dv NULL
pointer is returned on
.Dv EOF
or error.
.Sh BUGS
All information
is contained in a static area
so it must be copied if it is
to be saved.

.Nd get RPC port number
.Sh SYNOPSIS
.Ft int
.Fn getrpcport "char *host" "int prognum" "int versnum" "int proto"
.Sh DESCRIPTION
.Fn getrpcport
returns the port number for version
.Fa versnum
of the RPC program
.Fa prognum
running on
.Fa host
and using protocol
.Fa proto .
It returns 0 if it cannot contact the portmapper, or if
.Fa prognum
is not registered. If
.Fa prognum
is registered but not with version
.Fa versnum ,
it will still return a port number (for some version of the program)
indicating that the program is indeed registered.
The version mismatch will be detected upon the first call to the service.

.B getpublickey(netname, publickey)
.B char netname[\s-1MAXNETNAMELEN\s0+1];

.B char *passwd;
.fi
.SH DESCRIPTION
.IX "getpublickey function" "" "\fLgetpublickey()\fP function"
.IX "getsecretkey function" "" "\fLgetsecretkey()\fP function"
These routines are used to get public and secret keys from the
.SM YP
database.
.B getsecretkey(\|)
has an extra argument,
.IR passwd ,
which is used to decrypt the encrypted secret key stored in the database.
Both routines return 1 if they are successful in finding the key, 0 otherwise.
The keys are returned as
.SM NULL\s0-terminated,
hexadecimal strings.
If the password supplied to
.B getsecretkey(\|)
fails to decrypt the secret key, the routine will return 1 but the
.I secretkey
argument will be a
.SM NULL
string (``'').

.SH SYNOPSIS
.B /etc/publickey
.SH DESCRIPTION
.LP
.B /etc/publickey
is the public key database used for secure
networking.
Each entry in
the database consists of a network user
name (which may either refer to
a user or a hostname), followed by the user's
public key (in hex
notation), a colon, and then the user's
secret key encrypted with
its login password (also in hex notation).
.LP
This file is altered either by the user through the
.BR chkey (1)
command or by the system administrator through the
.BR newkey (8)
command.
The file
.B /etc/publickey
should only contain data on the NIS master machine, where it
is converted into the
.SM NIS
database
.BR publickey.byname .

.Sh DESCRIPTION
These routines are part of the
.Tn RPC
library. They implement
.Tn DES
Authentication. See
.Xr rpc 3
for further details about
.Tn RPC .
.Pp
The
.Fn authdes_create
is the first of two routines which interface to the
.Tn RPC
secure authentication system, known as
.Tn DES
authentication.
The second is
.Fn authdes_getucred ,
below.
.Pp
Note: the keyserver daemon
.Xr keyserv 8
must be running for the
.Tn DES
authentication system to work.
.Pp
.Fn Authdes_create ,
used on the client side, returns an authentication handle that
will enable the use of the secure authentication system.
The first parameter
.Fa name
is the network name, or
.Fa netname ,
of the owner of the server process.
This field usually
represents a
.Fa hostname
derived from the utility routine
.Fn host2netname ,
but could also represent a user name using
.Fn user2netname .
The second field is window on the validity of
the client credential, given in seconds. A small
window is more secure than a large one, but choosing
too small of a window will increase the frequency of
resynchronizations because of clock drift.
The third
parameter
.Fa addr
is optional. If it is
.Dv NULL ,
then the authentication system will assume
that the local clock is always in sync with the server's
clock, and will not attempt resynchronizations.
If an address
is supplied, however, then the system will use the address
for consulting the remote time service whenever
resynchronization
is required.
This parameter is usually the
address of the
.Tn RPC
server itself.
The final parameter
.Fa ckey
is also optional. If it is
.Dv NULL ,
then the authentication system will
generate a random
.Tn DES
key to be used for the encryption of credentials.
If it is supplied, however, then it will be used instead.
.Pp
.Fn Authdes_getucred ,
the second of the two
.Tn DES
authentication routines,
is used on the server side for converting a
.Tn DES
credential, which is
operating system independent, into a
.Ux
credential.
This routine differs from utility routine
.Fn netname2user
in that
.Fn authdes_getucred
pulls its information from a cache, and does not have to do a
Yellow Pages lookup every time it is called to get its information.
.Pp
.Fn Getnetname
installs the unique, operating-system independent netname of
the
caller in the fixed-length array
.Fa name .
Returns
.Dv TRUE
if it succeeds and
.Dv FALSE
if it fails.
.Pp
.Fn Host2netname
converts from a domain-specific hostname to an
operating-system independent netname.
Returns
.Dv TRUE
if it succeeds and
.Dv FALSE
if it fails.
Inverse of
.Fn netname2host .
.Pp
.Fn Key_decryptsession
is an interface to the keyserver daemon, which is associated
with
.Tn RPC Ns 's
secure authentication system (
.Tn DES
authentication).
User programs rarely need to call it, or its associated routines
.Fn key_encryptsession ,
.Fn key_gendes
and
.Fn key_setsecret .
System commands such as
.Xr login 1
and the
.Tn RPC
library are the main clients of these four routines.
.Pp
.Fn Key_decryptsession
takes a server netname and a
.Tn DES
key, and decrypts the key by
using the the public key of the the server and the secret key
associated with the effective uid of the calling process. It
is the inverse of
.Fn key_encryptsession .
.Pp
.Fn Key_encryptsession
is a keyserver interface routine.
It
takes a server netname and a des key, and encrypts
it using the public key of the the server and the secret key
associated with the effective uid of the calling process. It
is the inverse of
.Fn key_decryptsession .
.Pp
.Fn Key_gendes
is a keyserver interface routine.
It
is used to ask the keyserver for a secure conversation key.
Choosing one
.Qq random
is usually not good enough,
because
the common ways of choosing random numbers, such as using the
current time, are very easy to guess.
.Pp
.Fn Key_setsecret
is a keyserver interface routine.
It is used to set the key for
the effective
.Fa uid
of the calling process.
.Pp
.Fn Netname2host
converts from an operating-system independent netname to a
domain-specific hostname.
Returns
.Dv TRUE
if it succeeds and
.Dv FALSE
if it fails. Inverse of
.Fn host2netname .
.Pp
.Fn Netname2user
converts from an operating-system independent netname to a
domain-specific user ID.
Returns
.Dv TRUE
if it succeeds and
.Dv FALSE
if it fails.
Inverse of
.Fn user2netname .
.Pp
.Fn User2netname
converts from a domain-specific username to an operating-system
independent netname.
Returns
.Dv TRUE
if it succeeds and
.Dv FALSE
if it fails.
Inverse of
.Fn netname2user .

.LP
.B rstat_svc
is a server which returns performance statistics
obtained from the kernel.
These statistics are graphically displayed by the Sun Microsystems program,
.BR perfmeter (1).
The

.TH RTIME 3 "22 November 1987"
.SH NAME
rtime \- get remote time
.SH SYNOPSIS
.nf
.B #include <sys/types.h>
.B #include <sys/time.h>
.B #include <netinet/in.h>
.LP
.B int rtime(addrp, timep, timeout)
.B struct sockaddr_in \(**addrp;
.B struct timeval \(**timep;
.B struct timeval \(**timeout;
.fi
.SH DESCRIPTION
.B rtime(\|)
consults the Internet Time Server at the address pointed to by
.I addrp
and returns the remote time in the
.B timeval
struct pointed to by
.IR timep .
Normally, the
.SM UDP
protocol is used when consulting the Time Server.
The
.I timeout
parameter specifies how long the
routine should wait before giving
up when waiting for a reply. If
.I timeout
is specified as
.SM NULL\s0,
however, the routine will instead use
.SM TCP
and block until a reply is received from the time server.
.LP
The routine returns 0 if it is successful.
Otherwise,
it returns \-1 and
.B errno
is set to reflect the cause of the error.
.SH "SEE ALSO"

.TH XDR 3 "16 February 1988"
.SH NAME
xdr \- library routines for external data representation
.SH SYNOPSIS AND DESCRIPTION
.LP
These routines allow C programmers to describe
arbitrary data structures in a machine-independent fashion.
Data for remote procedure calls are transmitted using these
routines.
.LP
.ft B
.nf
.sp .5
xdr_array(xdrs, arrp, sizep, maxsize, elsize, elproc)
\s-1XDR\s0 *xdrs;
char **arrp;
u_int *sizep, maxsize, elsize;
xdrproc_t elproc;
.fi
.ft R
.IP
A filter primitive that translates between variable-length
arrays
and their corresponding external representations.
The
parameter
.I arrp
is the address of the pointer to the array, while
.I sizep
is the address of the element count of the array;
this element count cannot exceed
.IR maxsize .
The parameter
.I elsize
is the
.I sizeof
each of the array's elements, and
.I elproc
is an
.SM XDR
filter that translates between
the array elements' C form, and their external
representation.
This routine returns one if it succeeds, zero otherwise.
.br
.if t .ne 8
.LP
.ft B
.nf
.sp .5
xdr_bool(xdrs, bp)
\s-1XDR\s0 *xdrs;
bool_t *bp;
.fi
.ft R
.IP
A filter primitive that translates between booleans (C
integers)
and their external representations.
When encoding data, this
filter produces values of either one or zero.
This routine returns one if it succeeds, zero otherwise.
.br
.if t .ne 10
.LP
.ft B
.nf
.sp .5
xdr_bytes(xdrs, sp, sizep, maxsize)
\s-1XDR\s0 *xdrs;
char **sp;
u_int *sizep, maxsize;
.fi
.ft R
.IP
A filter primitive that translates between counted byte
strings and their external representations.
The parameter
.I sp
is the address of the string pointer.
The length of the
string is located at address
.IR sizep ;
strings cannot be longer than

This routine initializes the

The stream's data is written to a buffer of size
.IR sendsize ;
a value of zero indicates the system should use a suitable
default.
The stream's data is read from a buffer of size
.IR recvsize ;
it too can be set to a suitable default by passing a zero
value.
When a stream's output buffer is full,
.I writeit
is called. Similarly, when a stream's input buffer is empty,
.I readit
is called. The behavior of these two routines is similar to
the
system calls
.B read

except that
.I handle
is passed to the former routines as the first parameter.
Note: the

A filter primitive that translates between a discriminated C

It first
translates the discriminant of the union located at
.IR dscmp .
This discriminant is always an

Next the union located at

structures.
Each structure contains an ordered pair of
.RI [ value , proc ].
If the union's discriminant is equal to the associated
.IR value ,
then the
.I proc
is called to translate the union. The end of the
.B xdr_discrim(\|)
structure array is denoted by a routine of value
.SM NULL\s0.
If the discriminant is not found in the
