    Command:

    rexec_af

    
    
    

    SYNOPSIS

           #define _BSD_SOURCE             /* See feature_test_macros(7) */
           #include <netdb.h>
    
           int rexec(char **ahost, int inport, char *user,
                     char *passwd, char *cmd, int *fd2p);
    
           int rexec_af(char **ahost, int inport, char *user,
                        char *passwd, char *cmd, int *fd2p,
                        sa_family_t af);
    
    
    

    DESCRIPTION

           This interface is obsoleted by rcmd(3).
    
           The  rexec()  function looks up the host *ahost using gethostbyname(3),
           returning -1 if the host does not exist.  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;
           otherwise  the  environment  and  then  the  .netrc file in user's home
           directory are searched for appropriate information.  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; the call getservbyname("exec", "tcp") (see  getser-
           vent(3))  will return a pointer to a structure that contains the neces-
           sary port.  The protocol for connection is described in detail in  rex-
           ecd(8).
    
           If  the  connection  succeeds,  a socket in the Internet domain 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 setup, 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.  The diagnostic  information  returned  does  not
           include  remote  authorization  failure, as the secondary connection is
           set up after authorization has been verified.  If fd2p is 0,  then  the
           stderr (unit 2 of the remote command) will be made the same as the std-
           out 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.
    
       rexec_af()
           The rexec() function works  over  IPv4  (AF_INET).   By  contrast,  the
           rexec_af()  function  provides  an  extra argument, af, that allows the
           caller to select the protocol.   This  argument  can  be  specified  as
           AF_INET,  AF_INET6, or AF_UNSPEC (to allow the implementation to select
           the protocol).
    
    
    

    VERSIONS

           The rexec_af() function was added to glibc in version 2.2.
           not enabled on many sites; see rexecd(8) for explanations.
