DESCRIPTION

       Security Audit and Trailing Functionality

EXPORTS

       list_auth_users(Port) -> Users | []
       list_auth_users(Address, Port) -> Users | []
       list_auth_users(Port, Dir) -> Users | []

	      Types  Port = integer()

		     Dir = string()
		     Users = list() = [string()]

	      list_auth_users/1  ,  list_auth_users/2  and list_auth_users/3 returns a list of users that are currently authenticated. Authentica-
	      tions are stored for SecurityAuthTimeout seconds, and are then discarded.

       list_blocked_users(Address, Port) -> Users | []

	      Types  Port = integer()
		     Address = {A,B,C,D} | string() | undefined
		     Dir = string()
		     Users = list() = [string()]

	      list_blocked_users/1 , list_blocked_users/2 and list_blocked_users/3 returns a list of users that are currently blocked from access.

       block_user(User, Port, Dir, Seconds) -> true | {error, Reason}
       block_user(User, Address, Port, Dir, Seconds) -> true | {error, Reason}

	      Types  User = string()
		     Port = integer()
		     Address = {A,B,C,D} | string() | undefined
		     Dir = string()
		     Seconds = integer() | infinity
		     Reason = no_such_directory

	      block_user/4 and block_user/5 blocks the user User from the directory Dir for a specified amount of time.

       unblock_user(User, Port) -> true | {error, Reason}
       unblock_user(User, Address, Port) -> true | {error, Reason}
       unblock_user(User, Port, Dir) -> true | {error, Reason}
       unblock_user(User, Address, Port, Dir) -> true | {error, Reason}

	      Types  User = string()
		     Port = integer()
		     Address = {A,B,C,D} | string() | undefined
		     Dir = string()
		     Reason = term()

	      unblock_user/2 , unblock_user/3 and unblock_user/4 removes the user User from the list of blocked users for the Port (and Dir) spec-
	      ified.

THE SECURITYCALLBACKMODULE

       The  SecurityCallbackModule is a user written module that can receive events from the mod_security Erlang Webserver API module. This module
       only exports the function(s), event/4,5 , which are described below.

EXPORTS

       event(What, Port, Dir, Data) -> ignored
       event(What, Address, Port, Dir, Data) -> ignored

	      Types  What = atom()
		     Port = integer()
		     Address = {A,B,C,D} | string() <v>Dir = string()
		     Data = [Info]
		     Info = {Name, Value}

	      event/4 or event/4 is called whenever an event occurs in the mod_security Erlang Webserver API module ( event/4 is called if Address
	      is  undefined and event/5 otherwise). The What argument specifies the type of event that has occurred, and should be one of the fol-
	      lowing reasons; auth_fail (a failed user authentication), user_block (a user is being blocked from access) or user_unblock  (a  user
	      is being removed from the block list).

   Note:
       Note that the user_unblock event is not triggered when a user is removed from the block list explicitly using the unblock_user function.

NAME

       net_adm - Various Erlang Net Administration Routines

DESCRIPTION

       This module contains various network utility functions.

EXPORTS

       dns_hostname(Host) -> {ok, Name} | {error, Host}

	      Types  Host = atom() | string()
		     Name = string()

	      Returns the official name of Host , or {error, Host} if no such name is found. See also inet(3erl) .

       host_file() -> Hosts | {error, Reason}

	      Types  Hosts = [Host]
		     Host = atom()
		     Reason = term()

	      Reads  the  .hosts.erlang file, see the section Files below. Returns the hosts in this file as a list, or returns {error, Reason} if
	      the file could not be read. See file(3erl) for possible values of Reason .

       localhost() -> Name

	      Types  Name = string()

	      Returns the name of the local host. If Erlang was started with the -name command line flag, Name is the fully qualified name.

       names() -> {ok, [{Name, Port}]} | {error, Reason}
       names(Host) -> {ok, [{Name, Port}]} | {error, Reason}

	      Types  Name = string()
		     Port = int()
		     Reason = address | term()

	      Similar to epmd -names , see epmd(1) . Host defaults to the local host. Returns the names and associated port numbers of the  Erlang
	      nodes that epmd at the specified host has registered.

	      Returns {error, address} if epmd is not running. See inet(3erl) for other possible values of Reason .

	      (arne@dunn)1> net_adm:names().
	      {ok,[{"arne",40262}]}

       ping(Node) -> pong | pang

	      Types  Node = node()

	      Tries to set up a connection to Node . Returns pang if it fails, or pong if it is successful.

       world() -> [node()]
       world(Arg) -> [node()]

	      Types  Arg = silent | verbose

	      This  function  calls names(Host) for all hosts which are specified in the Erlang host file .hosts.erlang , collects the replies and
	      then evaluates ping(Node) on all those nodes. Returns the list of all nodes that were, successfully pinged.

	      Arg defaults to silent . If Arg == verbose , the function writes information about which nodes it is pinging to stdout.

	      This function can be useful when a node is started, and the names of the other nodes in the network are not initially known.

	      Failure: {error, Reason} if host_file() returns {error, Reason} .

       world_list(Hosts) -> [node()]
       world_list(Hosts, Arg) -> [node()]

	      Types  Hosts = [Host]
		     Host = atom()
		     Arg = silent | verbose

	      As world/0,1 , but the hosts are given as argument instead of being read from .hosts.erlang .

FILES

       The .hosts.erlang file consists of a number of host names written as Erlang terms. It is looked for in  the  current  work  directory,  the
       user's home directory, and $OTP_ROOT (the root directory of Erlang/OTP), in that order.

       The  format  of the .hosts.erlang file must be one host name per line. The host names must be within quotes as shown in the following exam-
       ple:

       ^ (new line)
