Name
       rexec - return stream to a remote command

Syntax
       rem = rexec(ahost, inport, user, passwd, cmd, fd2p);
       char **ahost;
       u_short inport;
       char *user, *passwd, *cmd;
       int *fd2p;

Description
       The  subroutine	looks  up the host *ahost using returning -1 if the host does not exist.  For further information, see Otherwise *ahost is
       set to the standard name of the host.  If a username and password are both specified, then these are used to authenticate  to  the  foreign
       host.  If all this fails, the user is prompted for the information.

       The  port  inport specifies which well-known DARPA Internet port to use for the connection; it will normally be the value returned from the
       call ``getservbyname("exec", "tcp")''.  For further information, see The protocol for connection is described in detail in

       If the call succeeds, a socket of type SOCK_STREAM is returned to the caller and given to the remote command as stdin and stdout.  If  fd2p
       is  nonzero,  then  an auxiliary channel to a control process will be set up, and a descriptor for it will be placed in *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  UNIX
       signal  numbers, to be forwarded to the process group of the command.  If fd2p is 0, then the stderr (unit 2 of the remote command) will be
       made the same as the 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.
