SFLWL(1)                 USER COMMANDS                   SFLWL(1)

NAME
     sflwl - Query Speak Freely Look Who's Listening client

SYNOPSIS
     sflwl [ -cdlmu ] [ -hhost[:port] ] [*]user_name ...

DESCRIPTION
     sflwl is a client program which requests contact information
     from  a server running the Speak Freely Look Who's Listening
     server (sflwld).  sflwl allows users to find one another and
     establish  Speak  Freely  conversations  even if one or both
     have dial-up Internet connections where the  host  name  and
     Internet address vary from session to session.

     Each user_name is matched against  the  E-mail  address  and
     full  user  name  of active users who have informed the Look
     Who's Listening site of their presence.   If  the  user_name
     occurs  within  either  of  these fields, the IP address and
     port on which matching users are listening are listed.   Op-
     tions allow different forms of output.

     If the user_name is preceded by an asterisk (*), only  exact
     matches with the user's E-mail address are reported.

OPTIONS
     -c        Output consists of the command  line  options  for
               sfspeaker to connect to the matching user(s).  For
               example, if you want to connect to a dial-up  user
               whose  E-mail address is smudley@internut.com, you
               can use the command:
                   sfmike -t `sflwl -c smudley@internut.com`
               to  connect  to  that  person,  as  long  as  he's
               currently connected to an Internet service provid-
               er and running Speak Freely, even you  don't  know
               the site name or IP address he's been assigned for
               the current session.

     -d        Enables debug output.

     -hhost:port
               The query is sent to the named host (and  optional
               port  number,  in  case  the  host doesn't use the
               standard port, 2076).  The -h option overrides any
               host  and  port specified by the SPEAKFREE_LWL_ASK
               and/or SPEAKFREE_LWL_TELL variables.

     -l        The list of hosts which matched the  user_name  is
               shown  in long form, including all information the
               users supplied to the Look Who's Listening server.

     -m        Shows the server status  message,  if  any.   This
               message provides information regarding the server,
               such as the World-Wide Web URL where it  publishes
               the list of active users.

     -u        Prints how-to-call information.

ENVIRONMENT VARIABLES
     If no host (and optional port number)  is  specified,  sflwl
     will    use   the   host   and   port   specified   by   the
     SPEAKFREE_LWL_ASK  environment  variable,  if  defined.   If
     SPEAKFREE_LWL_ASK  is  not  defined,  the host name is taken
     from the SPEAKFREE_LWL_TELL variable used  by  sfspeaker  to
     identify its Look Who's Listening host.

BUGS
     The number of matching items returned  is  limited  to  what
     will  fit  in a single 512 byte packet.  This is deliberate;
     users who wish to browse active  sites  should  consult  the
     HTML  file published by the Look Who's Listening site rather
     than make wild-card requests with sflwl.
