Skipole Network Monitor project is a simple network monitor with built in web server.

It allows the user to input host IP addresses, it then pings these hosts every five minutes and displays their status via a built-in web server, on port 8000.

So calling http://your_pc_address:8000 will display pages showing green, yellow or red host or group symbols.

Each host is pinged four times every five minutes, and symbols are displayed as:

green : if three or four pings are successfull
yellow : if only one or two are successfull
red : if all four fail

As well as hosts, group symbols are displayed, and can be opened to show hosts, or sub-groups nested within. The operator can create groups, and sub-groups via the gui.

Noname Network provides a powerful file-sharing network.

The Noname network is a gnutella-based network that features a different and more flexible protocol. The client and network currently support filesharing, but the protocol can be extended to support more features.

My Network Catalog is an indexing engine that allows Windows shares (or Samba shares) to be bound together over a local network.

My Network Catalog allows an easy centralized search of all the files available over the network.

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.
