Command Line Syntax
The generic syntax is:
listen [ options ]
Options
The order of the options is not important. Currently available options are:-
Getting Help
- -v [ a | b | c | g | p | s | t | u ]
- Verbose mode: Gives a running commentary on the program's attempts to read data in various
ways. As the amount of verbose output is substantial, the
-v
option can now be followed
by zero, one or more of the following flags (without space) in order to differentiate the verbose
output generated:
- a: Anchor relevant information
- b: Bindings to local file system
- c: Cache trace
- g: SGML trace
- p: Protocol module information
- s: SGML/HTML relevant information
- t: Thread trace
- u: URI relevant information
The -v
option without any appended options shows all
trace messages. An example is
-vpt
showing thread and protocol trace messages
- -version
- Prints out the version number of the software, and the version number of the WWW library, and
exits.
Configuration Options
- -port <n>
- Indicates the port number to listen on. Default is 80
- -backlog <n>
- Number of connections pending in the
listen
queue
