-/* (From RFC1521 and draft-ietf-dnssec-secext-03.txt)
-   The following encoding technique is taken from RFC 1521 by Borenstein
-   and Freed.  It is reproduced here in a slightly edited form for
-   convenience.
-
-   A 65-character subset of US-ASCII is used, enabling 6 bits to be
-   represented per printable character. (The extra 65th character, "=",
-   is used to signify a special processing function.)
-
-   The encoding process represents 24-bit groups of input bits as output
-   strings of 4 encoded characters. Proceeding from left to right, a
-   24-bit input group is formed by concatenating 3 8-bit input groups.
-   These 24 bits are then treated as 4 concatenated 6-bit groups, each
-   of which is translated into a single digit in the base64 alphabet.
-
-   Each 6-bit group is used as an index into an array of 64 printable
-   characters. The character referenced by the index is placed in the
-   output string.

-   Special processing is performed if fewer than 24 bits are available
-   at the end of the data being encoded.  A full encoding quantum is
-   always completed at the end of a quantity.  When fewer than 24 input
-   bits are available in an input group, zero bits are added (on the
-   right) to form an integral number of 6-bit groups.  Padding at the
-   end of the data is performed using the '=' character.
-
-   Since all base64 input is an integral number of octets, only the
-         -------------------------------------------------                       
-   following cases can arise:
-   
-       (1) the final quantum of encoding input is an integral
-           multiple of 24 bits; here, the final unit of encoded
-	   output will be an integral multiple of 4 characters
-	   with no "=" padding,
-       (2) the final quantum of encoding input is exactly 8 bits;
-           here, the final unit of encoded output will be two
-	   characters followed by two "=" padding characters, or
-       (3) the final quantum of encoding input is exactly 16 bits;
-           here, the final unit of encoded output will be three
-	   characters followed by one "=" padding character.

-.Sh DESCRIPTION
-These functions operate on ethernet addresses using an
-.Ar ether_addr
-structure, which is defined in the header file
-.Aq Pa netinet/if_ether.h :
-.Bd -literal -offset indent
-/*
- * The number of bytes in an ethernet (MAC) address.

-struct  ether_addr {
-        u_char octet[ETHER_ADDR_LEN];
-};
-.Ed
-.Pp
-The function
-.Fn ether_line
-scans
-.Ar l ,
-an
-.Tn ASCII
-string in
-.Xr ethers 5
-format and sets
-.Ar e
-to the ethernet address specified in the string and
-.Ar h
-to the hostname. This function is used to parse lines from
-.Pa /etc/ethers
-into their component parts.
-.Pp
-The
-.Fn ether_aton
-function converts an
-.Tn ASCII
-representation of an ethernet address into an
-.Ar ether_addr
-structure. Likewise,
-.Fn ether_ntoa
-converts an ethernet address specified as an
-.Ar ether_addr
-structure into an
-.Tn ASCII
-string.
-.Pp
-The
-.Fn ether_ntohost
-and
-.Fn ether_hostton
-functions map ethernet addresses to their corresponding hostnames
-as specified in the
-.Pa /etc/ethers
-database. 
-.Fn ether_ntohost
-converts from ethernet address to hostname, and
-.Fn ether_hostton
-converts from hostname to ethernet address.
-.Sh RETURN VALUES
-.Fn ether_line
-returns zero on success and non-zero if it was unable to parse
-any part of the supplied line
-.Ar l .
-It returns the extracted ethernet address in the supplied
-.Ar ether_addr
-structure
-.Ar e
-and the hostname in the supplied string
-.Ar h .
-.Pp
-On success, 
-.Fn ether_ntoa
-returns a pointer to a string containing an
-.Tn ASCII
-representation of an ethernet address. If it is unable to convert
-the supplied
-.Ar ether_addr
-structure, it returns a
-.Dv NULL
-pointer. Likewise,
-.Fn ether_aton
-returns a pointer to an
-.Ar ether_addr
-structure on success and a
-.Dv NULL
-pointer on failure.
-.Pp
-The
-.Fn ether_ntohost
-and
-.Fn ether_hostton
-functions both return zero on success or non-zero if they were
-unable to find a match in the
-.Pa /etc/ethers
-database.
-.Sh NOTES
-The user must insure that the hostname strings passed to the
-the
-.Fn ether_line ,
-.Fn ether_ntohost
-and
-.Fn ether_hostton
-functions are large enough to contain the returned hostnames.
-.Sh NIS INTERACTION
-If the
-.Pa /etc/ethers
-contains a line with a single + in it, the
-.Fn ether_ntohost
-and
-.Fn ether_hostton
-functions will attempt to consult the NIS
-.Pa ethers.byname
-and
-.Pa ethers.byaddr
-maps in addition to the data in the
-.Pa /etc/ethers
-file.
-.Sh SEE ALSO
-.Xr yp 4 ,
-.Xr ethers 5
-.Sh BUGS
-.Pp
-The
-.Fn ether_aton
-and
-.Fn ether_ntoa
-functions returns values that are stored in static memory areas
-which may be overwritten the next time they are called.
-.Sh HISTORY
-This particular implementation of the
-.Nm ethers
-library functions were written for and first appeared in
-.Fx 2.1 .

-.Sh DESCRIPTION
-The
-.Fn gethostbyname ,
-.Fn gethostbyname2
-and
-.Fn gethostbyaddr
-functions
-each return a pointer to an object with the
-following structure describing an internet host
-referenced by name or by address, respectively.
-This structure contains either the information obtained from the name server,
-.Xr named 8 ,
-or broken-out fields from a line in 
-.Pa /etc/hosts .
-If the local name server is not running these routines do a lookup in
-.Pa /etc/hosts .
-.Bd -literal
-struct	hostent {
-	char	*h_name;	/* official name of host */
-	char	**h_aliases;	/* alias list */
-	int	h_addrtype;	/* host address type */
-	int	h_length;	/* length of address */
-	char	**h_addr_list;	/* list of addresses from name server */
-};
-#define	h_addr  h_addr_list[0]	/* address, for backward compatibility */
-.Ed
-.Pp
-The members of this structure are:
-.Bl -tag -width h_addr_list
-.It Fa h_name
-Official name of the host.
-.It Fa h_aliases
-A NULL-terminated array of alternate names for the host.
-.It Fa h_addrtype
-The type of address being returned; usually
-.Dv AF_INET .
-.It Fa h_length
-The length, in bytes, of the address.
-.It Fa h_addr_list
-A NULL-terminated array of network addresses for the host.
-Host addresses are returned in network byte order.
-.It Fa h_addr
-The first address in
-.Fa h_addr_list ;
-this is for backward compatibility.
-.El
-.Pp
-When using the nameserver,
-.Fn gethostbyname
-and
-.Fn gethostbyname
-will search for the named host in the current domain and its parents
-unless the name ends in a dot.
-If the name contains no dot, and if the environment variable
-.Dq Ev HOSTALIASES
-contains the name of an alias file, the alias file will first be searched
-for an alias matching the input name.
-See
-.Xr hostname 7
-for the domain search procedure and the alias file format.
-.Pp
-The
-.Fn gethostbyname2
-function is an evolution of
-.Fn gethostbyname
-which is intended to allow lookups in address families other than
-.Dv AF_INET ,
-for example
-.Dv AF_INET6 .
-Currently the
-.Fa af
-argument must be specified as
-.Dv AF_INET
-else the function will return
-.Dv NULL
-after having set
-.Va h_errno
-to
-.Dv NETDB_INTERNAL
-.Pp
-The
-.Fn sethostent
-function
-may be used to request the use of a connected
-.Tn TCP
-socket for queries.
-If the
-.Fa stayopen
-flag is non-zero,
-this sets the option to send all queries to the name server using
-.Tn TCP
-and to retain the connection after each call to 
-.Fn gethostbyname ,
-.Fn gethostbyname2
-or
-.Fn gethostbyaddr .
-Otherwise, queries are performed using
-.Tn UDP
-datagrams.
-.Pp
-The
-.Fn endhostent
-function
-closes the
-.Tn TCP
-connection.
-.Pp
-The
-.Fn herror
-function writes a message to the diagnostic output consisting of the
-string parameter
-.Fa s ,
-the constant string ": ", and a message corresponding to the value of
-.Va h_errno .
-.Pp
-The
-.Fn hstrerror
-function returns a string which is the message text corresponding to the
-value of the
-.Fa err
-parameter.
-.Sh FILES
-.Bl -tag -width /etc/resolv.conf -compact
-.It Pa /etc/hosts
-.It Pa /etc/host.conf
-.It Pa /etc/resolv.conf
-.El
-.Sh DIAGNOSTICS
-Error return status from 
-.Fn gethostbyname ,
-.Fn gethostbyname2
-and
-.Fn gethostbyaddr
-is indicated by return of a null pointer.
-The external integer
-.Va h_errno
-may then be checked to see whether this is a temporary failure
-or an invalid or unknown host.
-The routine
-.Fn herror
-can be used to print an error message describing the failure.
-If its argument
-.Fa string
-is
-.Pf non Dv -NULL ,
-it is printed, followed by a colon and a space.
-The error message is printed with a trailing newline.
-.Pp
-The variable
-.Va h_errno
-can have the following values:
-.Bl -tag -width HOST_NOT_FOUND
-.It Dv HOST_NOT_FOUND
-No such host is known.
-.It Dv TRY_AGAIN
-This is usually a temporary error
-and means that the local server did not receive
-a response from an authoritative server.
-A retry at some later time may succeed.
-.It Dv NO_RECOVERY
-Some unexpected server failure was encountered.
-This is a non-recoverable error.
-.It Dv NO_DATA
-The requested name is valid but does not have an IP address; 
-this is not a temporary error.  
-This means that the name is known to the name server but there is no address
-associated with this name.
-Another type of request to the name server using this domain name
-will result in an answer;
-for example, a mail-forwarder may be registered for this domain.
-.El
-.Sh SEE ALSO
-.Xr resolver 3 ,
-.Xr hosts 5 ,
-.Xr hostname 7 ,
-.Xr named 8
-.Sh CAVEAT
-The
-.Fn gethostent
-function
-is defined, and
-.Fn sethostent
-and
-.Fn endhostent
-are redefined,
-when
-.Xr libc 3
-is built to use only the routines to lookup in
-.Pa /etc/hosts
-and not the name server.
-.Pp
-The
-.Fn gethostent
-function
-reads the next line of
-.Pa /etc/hosts ,
-opening the file if necessary.
-.Pp
-The
-.Fn sethostent
-function
-opens and/or rewinds the file
-.Pa /etc/hosts .
-If the
-.Fa stayopen
-argument is non-zero,
-the file will not be closed after each call to
-.Fn gethostbyname ,
-.Fn gethostbyname2
-or
-.Fn gethostbyaddr .
-.Pp
-The
-.Fn endhostent
-function
-closes the file.
-.Sh HISTORY
-The
-.Fn herror
-function appeared in 
-.Bx 4.3 .
-The
-.Fn endhostent ,
-.Fn gethostbyaddr ,
-.Fn gethostbyname ,
-.Fn gethostent ,
-and
-.Fn sethostent
-functions appeared in
-.Bx 4.2 .
-The
-.Fn gethostbyname2
-function first appeared in bind-4.9.4.
-.Sh BUGS
-These functions use static data storage;
-if the data is needed for future use, it should be
-copied before any subsequent calls overwrite it.
-Only the Internet
-address format is currently understood.

-.Sh NAME
-.Nm getnetent ,
-.Nm getnetbyaddr ,
-.Nm getnetbyname ,
-.Nm setnetent ,
-.Nm endnetent
-.Nd get network entry
-.Sh SYNOPSIS
-.Fd #include <netdb.h>
-.Ft struct netent *
-.Fn getnetent void
-.Ft struct netent *
-.Fn getnetbyname "const char *name"
-.Ft struct netent *
-.Fn getnetbyaddr "unsigned long net" "int type"
-.Ft void
-.Fn setnetent "int stayopen"
-.Ft void
-.Fn endnetent void
-.Sh DESCRIPTION
-The
-.Fn getnetent ,
-.Fn getnetbyname ,
-and
-.Fn getnetbyaddr
-functions
-each return a pointer to an object with the
-following structure
-containing the broken-out
-fields of a line in the network data base,
-.Pa /etc/networks .
-.Bd -literal -offset indent
-struct	netent {
-	char		*n_name;	/* official name of net */
-	char		**n_aliases;	/* alias list */
-	int		n_addrtype;	/* net number type */
-	unsigned long	n_net;		/* net number */
-};
-.Ed
-.Pp
-The members of this structure are:
-.Bl -tag -width n_addrtype
-.It Fa n_name
-The official name of the network.
-.It Fa n_aliases
-A zero terminated list of alternate names for the network.
-.It Fa n_addrtype
-The type of the network number returned; currently only AF_INET.
-.It Fa n_net
-The network number.  Network numbers are returned in machine byte
-order.
-.El
-.Pp
-The
-.Fn getnetent
-function
-reads the next line of the file, opening the file if necessary.
-.Pp
-The
-.Fn setnetent
-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 getnetbyname
-or
-.Fn getnetbyaddr .
-.Pp
-The
-.Fn endnetent
-function
-closes the file.
-.Pp
-The
-.Fn getnetbyname
-function
-and
-.Fn getnetbyaddr
-sequentially search from the beginning
-of the file until a matching
-net name or
-net address and type is found,
-or until
-.Dv EOF
-is encountered. The
-.Fa type
-must be
-.Dv AF_INET .
-Network numbers are supplied in host order.
-.Sh FILES
-.Bl -tag -width /etc/networks -compact
-.It Pa /etc/networks
-.El
-.Sh DIAGNOSTICS
-Null pointer
-(0) returned on
-.Dv EOF
-or error.
-.Sh SEE ALSO
-.Xr networks 5
-.Pp
-.%T RFC 1101
-.Sh HISTORY
-The
-.Fn getnetent ,
-.Fn getnetbyaddr ,
-.Fn getnetbyname ,
-.Fn setnetent ,
-and
-.Fn endnetent
-functions appeared in 
-.Bx 4.2 .
-.Sh BUGS
-The data space used by
-these functions is static; if future use requires the data, it should be
-copied before any subsequent calls to these functions overwrite it.
-Only Internet network
-numbers are currently understood.
-Expecting network numbers to fit
-in no more than 32 bits is probably
-naive.

-.Sh DESCRIPTION
-The
-.Fn getprotoent ,
-.Fn getprotobyname ,
-and
-.Fn getprotobynumber
-functions
-each return a pointer to an object with the
-following structure
-containing the broken-out
-fields of a line in the network protocol data base,
-.Pa /etc/protocols .
-.Bd -literal -offset indent
-.Pp
-struct	protoent {

-};
-.Ed
-.Pp
-The members of this structure are:
-.Bl -tag -width p_aliases
-.It Fa p_name
-The official name of the protocol.
-.It Fa p_aliases
-A zero terminated list of alternate names for the protocol.
-.It Fa p_proto
-The protocol number.

-.Pp
-The
-.Fn getprotoent
-function
-reads the next line of the file, opening the file if necessary.
-.Pp
-The
-.Fn setprotoent
-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 getprotobyname
-or
-.Fn getprotobynumber .
-.Pp
-The
-.Fn endprotoent
-function
-closes the file.
-.Pp
-The
-.Fn getprotobyname
-function
-and
-.Fn getprotobynumber
-sequentially search from the beginning
-of the file until a matching
-protocol name or
-protocol number is found,
-or until
-.Dv EOF
-is encountered.
-.Sh RETURN VALUES
-Null pointer
-(0) returned on
-.Dv EOF
-or error.
-.Sh FILES
-.Bl -tag -width /etc/protocols -compact
-.It Pa /etc/protocols
-.El
-.Sh SEE ALSO
-.Xr protocols 5
-.Sh HISTORY
-The
-.Fn getprotoent ,
-.Fn getprotobynumber ,
-.Fn getprotobyname ,
-.Fn setprotoent ,
-and
-.Fn endprotoent
-functions appeared in 
-.Bx 4.2 .
-.Sh BUGS
-These functions use a static data space;
-if the data is needed for future use, it should be
-copied before any subsequent calls overwrite it.
-Only the Internet
-protocols are currently understood.

-These functions use static data storage;

-.Sh DESCRIPTION
-The routines
-.Fn inet_aton ,
-.Fn inet_addr
-and
-.Fn inet_network
-interpret character strings representing
-numbers expressed in the Internet standard
-.Ql \&.
-notation.
-The
-.Fn inet_aton
-routine interprets the specified character string as an Internet address,
-placing the address into the structure provided.
-It returns 1 if the string was successfully interpreted,
-or 0 if the string is invalid.
-The
-.Fn inet_addr
-and
-.Fn inet_network
-functions return numbers suitable for use
-as Internet addresses and Internet network
-numbers, respectively.
-The routine
-.Fn inet_ntoa
-takes an Internet address and returns an
-.Tn ASCII
-string representing the address in
-.Ql \&.
-notation.  The routine
-.Fn inet_makeaddr
-takes an Internet network number and a local
-network address and constructs an Internet address
-from it.  The routines
-.Fn inet_netof
-and
-.Fn inet_lnaof
-break apart Internet host addresses, returning
-the network number and local network address part,
-respectively.
-.Pp
-All Internet addresses are returned in network
-order (bytes ordered from left to right).
-All network numbers and local address parts are
-returned as machine format integer values.
-.Sh INTERNET ADDRESSES
-Values specified using the
-.Ql \&.
-notation take one
-of the following forms:
-.Bd -literal -offset indent
-a.b.c.d
-a.b.c
-a.b
-a
-.Ed
-.Pp
-When four parts are specified, each is interpreted
-as a byte of data and assigned, from left to right,
-to the four bytes of an Internet address.  Note
-that when an Internet address is viewed as a 32-bit
-integer quantity on the
-.Tn VAX
-the bytes referred to
-above appear as
-.Dq Li d.c.b.a .
-That is,
-.Tn VAX
-bytes are
-ordered from right to left.
-.Pp
-When a three part address is specified, the last
-part is interpreted as a 16-bit quantity and placed
-in the right-most two bytes of the network address.
-This makes the three part address format convenient
-for specifying Class B network addresses as
-.Dq Li 128.net.host .
-.Pp
-When a two part address is supplied, the last part
-is interpreted as a 24-bit quantity and placed in
-the right most three bytes of the network address.
-This makes the two part address format convenient
-for specifying Class A network addresses as
-.Dq Li net.host .
-.Pp
-When only one part is given, the value is stored
-directly in the network address without any byte
-rearrangement.
-.Pp
-All numbers supplied as
-.Dq parts
-in a
-.Ql  \&.
-notation
-may be decimal, octal, or hexadecimal, as specified
-in the C language (i.e., a leading 0x or 0X implies
-hexadecimal; otherwise, a leading 0 implies octal;
-otherwise, the number is interpreted as decimal).
-.Pp
-The
-.Fn inet_aton
-and
-.Fn inet_ntoa
-functions are semi-deprecated in favor of the
-.Xr addr2ascii 3
-family.  However, since those functions are not yet widely implemented,
-portable programs cannot rely on their presence and will continue
-to use the
-.Xr inet 3
-functions for some time.
-.Sh DIAGNOSTICS
-The constant
-.Dv INADDR_NONE
-is returned by
-.Fn inet_addr
-and
-.Fn inet_network
-for malformed requests.
-.Sh SEE ALSO
-.Xr addr2ascii 3 ,
-.Xr gethostbyname 3 ,
-.Xr getnetent 3 ,
-.Xr hosts 5 ,
-.Xr networks 5
-.Sh HISTORY
-These
-functions appeared in 
-.Bx 4.2 .
-.Sh BUGS
-The value
-.Dv INADDR_NONE
-(0xffffffff) is a valid broadcast address, but
-.Fn inet_addr
-cannot return that value without indicating failure.
-The newer
-.Fn inet_aton
-function does not share this problem.
-The problem of host byte ordering versus network byte ordering is
-confusing.
-The string returned by
-.Fn inet_ntoa
-resides in a static memory area.
-.Pp
-Inet_addr should return a
-.Fa struct in_addr .

-.Dd June 17, 1996
-.Dt LINK_ADDR 3
-.Os BSD 4.4
-.Sh NAME
-.Nm link_addr ,
-.Nm link_ntoa
-.Nd elementary address specification routines for link level access
-.Sh SYNOPSIS
-.Fd #include <sys/types.h>
-.Fd #include <sys/socket.h>
-.Fd #include <net/if_dl.h>
-.Ft void
-.Fn link_addr "const char *addr" "struct sockaddr_dl *sdl"
-.Ft char *
-.Fn link_ntoa "const struct sockaddr_dl *sdl"
-.Sh DESCRIPTION
-The routine
-.Fn link_addr
-interprets character strings representing
-link-level addresses, returning binary information suitable
-for use in system calls.
-The routine
-.Fn link_ntoa
-takes
-a link-level
-address and returns an
-.Tn ASCII
-string representing some of the information present,
-including the link level address itself, and the interface name
-or number, if present.
-This facility is experimental and is
-still subject to change.
-.Pp
-For
-.Fn link_addr ,
-the string
-.Fa addr
-may contain
-an optional network interface identifier of the form
-.Dq "name unit-number" ,
-suitable for the first argument to
-.Xr ifconfig 8 ,
-followed in all cases by a colon and
-an interface address in the form of
-groups of hexadecimal digits
-separated by periods.
-Each group represents a byte of address;
-address bytes are filled left to right from
-low order bytes through high order bytes.
-.Pp
-.\" A regular expression may make this format clearer:
-.\" .Bd -literal -offset indent
-.\" ([a-z]+[0-9]+:)?[0-9a-f]+(\e.[0-9a-f]+)*
-.\" .Ed
-.\" .Pp
-Thus
-.Li le0:8.0.9.13.d.30
-represents an ethernet address
-to be transmitted on the first Lance ethernet interface.
-.Pp
-The direct use of these functions is deprecated in favor of the
-.Xr addr2ascii 3
-interface; however, portable programs cannot rely on the latter as it is
-not yet widely implemented.
-.Sh RETURN VALUES
-.Fn link_ntoa
-always returns a null terminated string.
-.Fn link_addr
-has no return value.
-(See
-.Sx BUGS . )
-.Sh SEE ALSO
-.Xr addr2ascii 3
-.\" .Xr iso 4
-.Sh HISTORY
-The
-.Fn link_addr
-and
-.Fn link_ntoa
-functions appeared in 
-.Bx 4.3 Reno  .
-.Sh BUGS
-The returned values for link_ntoa
-reside in a static memory area.
-.Pp
-The function
-.Fn link_addr
-should diagnose improperly formed input, and there should be an unambiguous
-way to recognize this.
-.Pp
-If the
-.Va sdl_len
-field of the link socket address
-.Fa sdl
-is 0,
-.Fn link_ntoa
-will not insert a colon before the interface address bytes.
-If this translated address is given to
-.Fn link_addr
-without inserting an initial colon,
-the latter will not interpret it correctly.

-.Sh DESCRIPTION
-The routine

-interprets character strings representing

-addresses, returning binary information suitable
-for use in system calls.
-The routine
-.Fn ns_ntoa
-takes
-.Tn XNS
-addresses and returns
-.Tn ASCII
-strings representing the address in a
-notation in common use in the Xerox Development Environment:
-.Bd -filled -offset indent
-<network number>.<host number>.<port number>
-.Ed
-.Pp
-Trailing zero fields are suppressed, and each number is printed in hexadecimal,
-in a format suitable for input to 
-.Fn ns_addr .
-Any fields lacking super-decimal digits will have a
-trailing
-.Ql H
-appended.
-.Pp
-Unfortunately, no universal standard exists for representing
-.Tn XNS
-addresses.
-An effort has been made to insure that
-.Fn ns_addr
-be compatible with most formats in common use.
-It will first separate an address into 1 to 3 fields using a single delimiter
-chosen from
-period
-.Ql \&. ,
-colon
-.Ql \&:
-or pound-sign
-.Ql \&# .
-Each field is then examined for byte separators (colon or period).
-If there are byte separators, each subfield separated is taken to be
-a small hexadecimal number, and the entirety is taken as a network-byte-ordered
-quantity to be zero extended in the high-network-order bytes.
-Next, the field is inspected for hyphens, in which case
-the field is assumed to be a number in decimal notation
-with hyphens separating the millenia.
-Next, the field is assumed to be a number:
-It is interpreted
-as hexadecimal if there is a leading
-.Ql 0x
-(as in C),
-a trailing
-.Ql H
-(as in Mesa), or there are any super-decimal digits present.
-It is interpreted as octal is there is a leading
-.Ql 0
-and there are no super-octal digits.
-Otherwise, it is converted as a decimal number.
-.Sh RETURN VALUES
-None. (See
-.Sx BUGS . )
-.Sh SEE ALSO

-.Xr networks 5
-.Sh HISTORY
-The

-.Sh BUGS
-The string returned by
-.Fn ns_ntoa
-resides in a static memory area.
-The function

-should diagnose improperly formed input, and there should be an unambiguous
-way to recognize this.

-.Dt RCMD 3
-.Os BSD 4.2
-.Sh NAME
-.Nm rcmd ,
-.Nm rresvport ,
-.Nm iruserok ,
-.Nm ruserok
-.Nd routines for returning a stream to a remote command
-.Sh SYNOPSIS
-.Fd #include <unistd.h>
-.Ft int
-.Fn rcmd "char **ahost" "int inport" "const char *locuser" "const char *remuser" "const char *cmd" "int *fd2p"
-.Ft int
-.Fn rresvport "int *port"
-.Ft int
-.Fn iruserok "u_long raddr" "int superuser" "const char *ruser" "const char *luser"
-.Ft int
-.Fn ruserok "const char *rhost" "int superuser" "const char *ruser" "const char *luser"
-.Sh DESCRIPTION
-The
-.Fn rcmd
-function
-is used by the super-user to execute a command on
-a remote machine using an authentication scheme based
-on reserved port numbers.
-The
-.Fn rresvport
-function
-returns a descriptor to a socket
-with an address in the privileged port space.
-The
-.Fn ruserok
-function
-is used by servers
-to authenticate clients requesting service with
-.Fn rcmd .
-All three functions are present in the same file and are used
-by the
-.Xr rshd 8
-server (among others).
-.Pp
-The
-.Fn rcmd
-function
-looks up the host
-.Fa *ahost
-using
-.Xr gethostbyname 3 ,
-returning \-1 if the host does not exist.
-Otherwise
-.Fa *ahost
-is set to the standard name of the host
-and a connection is established to a server
-residing at the well-known Internet port
-.Fa inport .
-.Pp
-If the connection succeeds,
-a socket in the Internet domain of type
-.Dv SOCK_STREAM
-is returned to the caller, and given to the remote
-command as 
-.Em stdin
-and
-.Em stdout .
-If
-.Fa fd2p
-is non-zero, then an auxiliary channel to a control
-process will be set up, and a descriptor for it will be placed
-in
-.Fa *fd2p .
-The control process will return diagnostic
-output from the command (unit 2) on this channel, and will also
-accept bytes on this channel as being
-.Tn UNIX
-signal numbers, to be
-forwarded to the process group of the command.
-If
-.Fa fd2p
-is 0, then the 
-.Em stderr
-(unit 2 of the remote
-command) will be made the same as the 
-.Em stdout
-and no
-provision is made for sending arbitrary signals to the remote process,
-although you may be able to get its attention by using out-of-band data.
-.Pp
-The protocol is described in detail in
-.Xr rshd 8 .
-.Pp
-The
-.Fn rresvport
-function is used to obtain a socket with a privileged
-address bound to it.  This socket is suitable for use
-by 
-.Fn rcmd
-and several other functions.  Privileged Internet ports are those
-in the range 0 to 1023.  Only the super-user
-is allowed to bind an address of this sort to a socket.
-.Pp
-The
-.Fn iruserok
-and
-.Fn ruserok
-functions take a remote host's IP address or name, as returned by the
-.Xr gethostbyname 3
-routines, two user names and a flag indicating whether the local user's
-name is that of the super-user.
-Then, if the user is
-.Em NOT
-the super-user, it checks the
-.Pa /etc/hosts.equiv
-file.
-If that lookup is not done, or is unsuccessful, the
-.Pa .rhosts
-in the local user's home directory is checked to see if the request for
-service is allowed.
-.Pp
-If this file does not exist, is not a regular file, is owned by anyone
-other than the user or the super-user, or is writable by anyone other
-than the owner, the check automatically fails.
-Zero is returned if the machine name is listed in the
-.Dq Pa hosts.equiv
-file, or the host and remote user name are found in the
-.Dq Pa .rhosts
-file; otherwise
-.Fn iruserok
-and
-.Fn ruserok
-return \-1.
-If the local domain (as obtained from
-.Xr gethostname 3 )
-is the same as the remote domain, only the machine name need be specified.
-.Pp
-The
-.Fn iruserok
-function is strongly preferred for security reasons.
-It requires trusting the local DNS at most, while the
-.Fn ruserok
-function requires trusting the entire DNS, which can be spoofed.
-.Sh DIAGNOSTICS
-The
-.Fn rcmd
-function
-returns a valid socket descriptor on success.
-It returns \-1 on error and prints a diagnostic message on the standard error.
-.Pp
-The
-.Fn rresvport
-function
-returns a valid, bound socket descriptor on success.
-It returns \-1 on error with the global value
-.Va errno
-set according to the reason for failure.
-The error code
-.Dv EAGAIN
-is overloaded to mean ``All network ports in use.''

-.Sh DESCRIPTION
-These routines are used for making, sending and interpreting
-query and reply messages with Internet domain name servers.
-.Pp
-Global configuration and state information that is used by the
-resolver routines is kept in the structure
-.Em _res .
-Most of the values have reasonable defaults and can be ignored.
-Options
-stored in
-.Em _res.options
-are defined in
-.Pa resolv.h
-and are as follows.
-Options are stored as a simple bit mask containing the bitwise ``or''
-of the options enabled.
-.Bl -tag -width RES_DEFNAMES
-.It Dv RES_INIT
-True if the initial name server address and default domain name are
-initialized (i.e.,
-.Fn res_init
-has been called).
-.It Dv RES_DEBUG
-Print debugging messages.
-.It Dv RES_AAONLY
-Accept authoritative answers only.
-With this option,
-.Fn res_send
-should continue until it finds an authoritative answer or finds an error.
-Currently this is not implemented.
-.It Dv RES_USEVC
-Use
-.Tn TCP
-connections for queries instead of
-.Tn UDP
-datagrams.
-.It Dv RES_STAYOPEN
-Used with
-.Dv RES_USEVC
-to keep the
-.Tn TCP
-connection open between
-queries.
-This is useful only in programs that regularly do many queries.
-.Tn UDP
-should be the normal mode used.
-.It Dv RES_IGNTC
-Unused currently (ignore truncation errors, i.e., don't retry with
-.Tn TCP ) .
-.It Dv RES_RECURSE
-Set the recursion-desired bit in queries.
-This is the default.
-.Pf ( Fn res_send
-does not do iterative queries and expects the name server
-to handle recursion.)
-.It Dv RES_DEFNAMES
-If set,
-.Fn res_search
-will append the default domain name to single-component names
-(those that do not contain a dot).
-This option is enabled by default.
-.It Dv RES_DNSRCH
-If this option is set,
-.Fn res_search
-will search for host names in the current domain and in parent domains; see
-.Xr hostname 7 .
-This is used by the standard host lookup routine
-.Xr gethostbyname 3 .
-This option is enabled by default.
-.It Dv RES_NOALIASES
-This option turns off the user level aliasing feature controlled by the
-.Dq Ev HOSTALIASES
-environment variable.  Network daemons should set this option.
-.El
-.Pp
-The
-.Fn res_init
-routine
-reads the configuration file (if any; see
-.Xr resolver 5 )
-to get the default domain name,
-search list and
-the Internet address of the local name server(s).
-If no server is configured, the host running
-the resolver is tried.
-The current domain name is defined by the hostname
-if not specified in the configuration file;
-it can be overridden by the environment variable
-.Ev LOCALDOMAIN .
-This environment variable may contain several blank-separated
-tokens if you wish to override the
-.Em "search list"
-on a per-process basis.  This is similar to the
-.Em search
-command in the configuration file.
-Another environment variable (
-.Dq Ev RES_OPTIONS
-can be set to
-override certain internal resolver options which are otherwise
-set by changing fields in the
-.Em _res
-structure or are inherited from the configuration file's
-.Em options
-command.  The syntax of the
-.Dq Ev RES_OPTIONS
-environment variable is explained in
-.Xr resolver 5 .
-Initialization normally occurs on the first call
-to one of the following routines.
-.Pp
-The
-.Fn res_query
-function provides an interface to the server query mechanism.
-It constructs a query, sends it to the local server,
-awaits a response, and makes preliminary checks on the reply.
-The query requests information of the specified
-.Fa type
-and
-.Fa class
-for the specified fully-qualified domain name
-.Fa dname .
-The reply message is left in the
-.Fa answer
-buffer with length
-.Fa anslen
-supplied by the caller.
-.Pp
-The
-.Fn res_search
-routine makes a query and awaits a response like
-.Fn res_query ,
-but in addition, it implements the default and search rules
-controlled by the
-.Dv RES_DEFNAMES
-and
-.Dv RES_DNSRCH
-options.
-It returns the first successful reply.
-.Pp
-The remaining routines are lower-level routines used by
-.Fn res_query .
-The
-.Fn res_mkquery
-function
-constructs a standard query message and places it in
-.Fa buf .
-It returns the size of the query, or \-1 if the query is
-larger than
-.Fa buflen .
-The query type
-.Fa op
-is usually
-.Dv QUERY ,
-but can be any of the query types defined in
-.Aq Pa arpa/nameser.h .
-The domain name for the query is given by
-.Fa dname .
-.Fa Newrr
-is currently unused but is intended for making update messages.
-.Pp
-The
-.Fn res_send
-routine
-sends a pre-formatted query and returns an answer.
-It will call
-.Fn res_init
-if
-.Dv RES_INIT
-is not set, send the query to the local name server, and
-handle timeouts and retries.
-The length of the reply message is returned, or
-\-1 if there were errors.
-.Pp
-The
-.Fn dn_comp
-function
-compresses the domain name
-.Fa exp_dn
-and stores it in
-.Fa comp_dn .
-The size of the compressed name is returned or \-1 if there were errors.
-The size of the array pointed to by
-.Fa comp_dn
-is given by
-.Fa length .
-The compression uses
-an array of pointers
-.Fa dnptrs
-to previously-compressed names in the current message.
-The first pointer points to
-to the beginning of the message and the list ends with
-.Dv NULL .
-The limit to the array is specified by
-.Fa lastdnptr .
-A side effect of
-.Fn dn_comp
-is to update the list of pointers for
-labels inserted into the message
-as the name is compressed.
-If
-.Em dnptr
-is
-.Dv NULL, names are not compressed.
-If
-.Fa lastdnptr
-is
-.Dv NULL ,
-the list of labels is not updated.
-.Pp
-The
-.Fn dn_expand
-entry
-expands the compressed domain name
-.Fa comp_dn
-to a full domain name
-The compressed name is contained in a query or reply message;
-.Fa msg
-is a pointer to the beginning of the message.
-The uncompressed name is placed in the buffer indicated by
-.Fa exp_dn
-which is of size
-.Fa length .
-The size of compressed name is returned or \-1 if there was an error.
