SFLWL(1)                                                 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 informa­
       tion 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  ses­
       sion.

       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.
       Options allow different forms of output.

       If the user_name is preceded by an asterisk (*), only  ex­
       act 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@inter­
                 nut.com, you can use the command:
                    sfmike -t `sflwl -c smudley@internut.com`
                 to  connect to that person, as long as he's cur­
                 rently connected to an Internet service provider
                 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 option­
                 al port number, in case the host doesn't use the
                 standard  port,  2076).  The -h option overrides
                 any  host  and  port  specified  by  the  SPEAK­
                 FREE_LWL_ASK   and/or  SPEAKFREE_LWL_TELL  vari­
                 ables.

       -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 serv­
                 er, such as the World-Wide Web URL where it pub­
                 lishes 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 SPEAK­
       FREE_LWL_ASK environment variable, if defined.  If  SPEAK­
       FREE_LWL_ASK  is  not defined, the host name is taken from
       the SPEAKFREE_LWL_TELL variable used by sfspeaker to iden­
       tify 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.
