rusers(3RPC)                                                   RPC Library Functions                                                  rusers(3RPC)

NAME

       rusers, rnusers - return information about users on remote machines

SYNOPSIS

       cc [ flag ... ] file ... -lrpcsvc [ library ... ]
       #include <rpc/rpc.h>
       #include <rpcsvc/rusers.h>

       enum clnt_stat rusers(char *host, struct utmpidlearr *up);

       int rnusers(char *host);

PROTOCOL

       /usr/include/rpcsvc/rusers.x

DESCRIPTION

       These  routines  require  that  the rpc.rusersd(1M) daemon be configured and available on the remote system indicated by host. The rusers()
       protocol is used to retrieve information about users logged in on the remote system.

       rusers() fills the utmpidlearr structure with data about host, and returns 0 if successful. up  must  point  to  an  allocated  utmpidlearr
       structure.  If  rusers()  returns  successful  it  will  have allocated data structures within the up structure, which should be freed with
       xdr_free(3NSL) when you no longer need them:

       xdr_free(xdr_utimpidlearr, up);

       On error, the returned value can be interpreted as an  enum clnt_stat and can be displayed with clnt_perror(3NSL) or  clnt_sperrno(3NSL).

       See the header  <rpcsvc/rusers.h> for a definition of struct  utmpidlearr.

       rnusers() returns the number of users logged on to host (-1 if it cannot determine that number).

       The following  XDR routines are available in librpcsvc:

       xdr_utmpidlearr

NAME

       rpc_clnt_auth,  auth_destroy,  authnone_create,	authsys_create, authsys_create_default - library routines for client side remote procedure
       call authentication

SYNOPSIS

       void auth_destroy(AUTH *auth);

       AUTH *authnone_create	(void)

       AUTH *authsys_create(const cha r*host,  const uid_t uid, const gid_t gid,
	    const int len, const gid_t *aup_gids);

       AUTH *authsys_create_default(void)

DESCRIPTION

       These routines are part of the RPC library that allows C language programs to make procedure calls on other machines  across  the  network,
       with desired authentication.

       These routines are normally called after creating the CLIENT handle. The cl_auth field of the CLIENT structure should be initialized by the
       AUTH structure returned by some of the following routines. The client's authentication information is passed to the  server  when  the  RPC
       call is made.

       Only the NULL and the SYS style of authentication is discussed here. For the DES style authentication, please refer to secure_rpc(3NSL).

       The NULL and SYS style of authentication are safe in multithreaded applications. For the MT-level of the DES style, see its pages.

   Routines
       The following routines require that the header <rpc/rpc.h> be included (see rpc(3NSL) for the definition of the AUTH data structure).

	 #include <rpc/rpc.h>

       auth_destroy()		 A  function macro that destroys the authentication information associated with auth. Destruction usually involves
				 deallocation of private data structures. The use of auth is undefined after calling auth_destroy().

       authnone_create()	 Create and return an RPC authentication handle that passes nonusable authentication information with each  remote
				 procedure call. This is the default authentication used by RPC.

       authsys_create() 	 Create  and  return an RPC authentication handle that contains AUTH_SYS authentication information. The parameter
				 host is the name of the machine on which the information was created; uid is the  user's  user  ID;  gid  is  the
				 user's current group ID; len and aup_gids refer to a counted array of groups to which the user belongs.

       authsys_create_default	 Call authsys_create() with the appropriate parameters.
