The usual reason for asking this question is that you want to restart a server but can't because you get a message "can't bind to port". There are adb scripts to close a FIN_WAIT_2 socket, I don't understand why you're having trouble with it. HP also has a program called ndd which can close a connection. But you shouldn't have to do this. Instead you address the real problem which is that the server has a bug that should be fixed.

There are two ways to ignore FIN_WAIT_2 sockets under unix. First, a program like inetd can do the bind at boot-up time and pass off new connections to the server as they arrive. Second, the server can simply set the SO_REUSEADDR option to indicate that it would prefer to ignore them.

You must have a server that does not want to run under inetd and it doesn't set SO_REUSEADDR. Ask whoever wrote the server to fix that. It takes one line of code to set SO_REUSEADDR and then you will have no more problem.

jifty::script::server

Jifty::Script::Server(3pm)				User Contributed Perl Documentation				Jifty::Script::Server(3pm)

NAME

       Jifty::Script::Server - A standalone webserver for your Jifty application

SYNOPSIS

	   jifty server
	   jifty server --port 6666
	   jifty server --stop

DESCRIPTION

       Starts and stops Jifty's standalone web server.

   options
       --port  The port to run the server on. Overrides the port in the config file, if it is set there. The default port is 8888.

       --user USER
	       The user to become after binding to the port.  It is advised that you use this when binding to low ports, instead of running as
	       "root".	This option only works if the server is using a Net::Server subclass.

       --group GROUP
	       The group to become after binding to the port.  Like "--user", this option only works if the server is using a Net::Server
	       subclass.

       --host HOSTNAME
	       The host to bind to.  This option only works if the server is using a Net::Server subclass.

       --stop  Stops the server, if it is running.  This is accomplished by reading the PID from "var/jifty-server.pid"

       --restart
	       restart the server, if it is running. This is accomplished by killing the child pid, and let parent pid create a new one

       --sigready SIGNAL
	       Sets the signal number that should be sent to the server's parent process when the server is ready to accept connections.

       --quiet Reduces the amount of debug output sent by the server

       --dbiprof
	       Turns on DBI profiling; see DBI::ProfileDumper.

       --help  Print a brief help message and exits.

       --man   Prints the manual page and exits.

DESCRIPTION

       When you're getting started with Jifty, this is the server you want. It's lightweight and easy to work with.

METHODS

   run
       "run" takes no arguments, but starts up a Jifty server process for you.
