My first ever Kommander script that I did in an effort to learn the Kommander scripting engine/style and to have something useful.

Built with Kommander Editor 1.2

Network FIFO project is a network object that provides data transfering tunnel across network in first in/first out manner.

Simply put,

fifo server file is: monotech_fifo.pl
This script require Net::Server::NonBlocking at least 4.1(you can grab from CPAN)

% perl monotech_fifo.pl < address > < port >

and itll show up like this:

[root@WongWai monotech_fifo]# perl monotech_fifo.pl 192.168.3.52 12000
Listen on 192.168.3.52:20005
Listen on 192.168.3.52:12000

12000 is the port in which the fifo resides.
20005 is the port in which backoffice management resides.

--------------------------------------------------

port 20005 in which the management control resides can be accessed by "admin.pl"

% perl admin.pl < address >

for example

perl admin.pl 192.168.3.52

itll show something like this:

message>

where you can type some commands and press enter

the commands are:

message>readers
message>flush

(flush is the command that read all socket buffer of the admin client socket)

to show all reader in the fifo, it is very useful when some reader is connection disconnected by his ISP or readers machine hangs, the fifo will hold his connection forever (It is because the monotech_fifo.pl doesnt set SO_KEEPALIVE and TCP_KEEPALIVE which will be fixed in the future)

and

message>kill_reader[tab]< fifo name >

to kill any connection of < fifo name >

This package is heavily used by my company, so it is likely reliable.
