+.Dt RCMDSH 3
+.Os OpenBSD
+.Sh NAME
+.Nm rcmd
+.Nd return a stream to a remote command as unprivileged user
+.Sh SYNOPSIS
+.Fd #include <unistd.h>
+.Ft int
+.Fn rcmdsh "char **ahost" "int inport" "const char *locuser" "const char *remuser" "const char *cmd" "char *rshprog"
+.Sh DESCRIPTION
+The
+.Fn rcmdsh
+function
+is used by normal users to execute a command on
+a remote machine using an authentication scheme based
+on reserved port numbers using
+.Xr rshd 8
+or the value of
+.Fa rshprog
+(if non-NULL).
+.Pp
+The
+.Fn rcmdsh
+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
+.Li shell/tcp
+(or whatever port is used by
+.Fa rshprog
+).  The parameter
+.Fa inport
+is ignored; it is only included to provide an interface similar to
+.Xr rcmd 3 .
+.Pp
+If the connection succeeds,
+a socket in the
+.Tn UNIX
+domain of type
+.Dv SOCK_STREAM
+is returned to the caller, and given to the remote
+command as 
+.Em stdin
+and
+.Em stdout ,
+and
+.Em stderr .
+.Sh DIAGNOSTICS
+The
+.Fn rcmdsh
+function
+returns a valid socket descriptor on success.
+It returns \-1 on error and prints a diagnostic message on the standard error.
+.Sh SEE ALSO
+.Xr rsh 1 ,
+.Xr socketpair 2 ,
+.Xr rcmd 3 ,
+.Xr rshd 8
+.Sh BUGS
+If
+.Xr rsh 1
+gets an error a file descriptor is still returned instead of \-1.
+.Sh HISTORY
+The
+.Fn rcmdsh
+function first appeared in
+.Bx Open .
