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. Options 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 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 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.
