TransData Version 1.01 Manual

TransData is an application capable of transporting data (like files or chat
text) over a network or the internet. In order to exchange files or chat, there
must be a server and at least one client that is connected to the server.
1) How to create a server
Run TransData and click "Start Server". Enter the port you wish to use (if your
computer is using a firewall, you must choose an open port which is not protected
by the firewall.). Commonly used ports are 1200, 80
(http://-port, the port your system uses for internet surfing) or 1214,
the port KaZaA uses). After entering a port, click "Start server"
If TransData says "TransData Server is bound to port xxx" then the server
is correctly running and a client can connect to it using the port xxx (replace
xxx with the port number you entered).
If TransData says "Could not bind to port xxx" the port you entered is
blocked, either by a firewall or by an application using this port. Try using
the ports 80, 1214, 1661, 1771 or review your firewall configuration to find out
which ports are open and which ports are closed.
2) How to create a client
Run TransData and click "Start Client". Enter the name you wish to use (the name
you enter will be used by the server application to identify you when you connect
to it).
Connecting the client to the server via LAN
Then, enter the ip address of the server (you might need to ask the user that
created the server for it) and the port the server set up. If the client computer
is connected to the server via LAN, then the server ip-address can be found
in the "Start/Control Panel/Network settings" on the server computer.
Another way to find out the ip address of the server is clicking "Start/run" on
the client and entering "cmd" to run the console. Enter "ping SERVERNAME" - the
ip-address will be displayed together with ping statistics (replace SERVERNAME
by the name of the computer running the server).
Connecting the client to the server via Internet (Modem, ISDN or DSL)
If the server and client should be connected via internet, it is at first necessary
to find out the ip address that is used by the server for the internet connection.
In most cases, especially when using ISDN or a Modem to connect
to the internet, the internet provider sets the ip-address, and therefore the
server every time has a different address. In that case, you can ask the server
user to visit
http://www.showmyip.com/.
This site tells the server what ip address it uses - enter this ip-address on
the TransData client to connect to it.
After entering the client name, server ip and port, click "connect". If you
get the error:
ClientCan't connect to xxx
Host refused connection
This means that either the server ip could not be found or the port is closed
(either on the client or the server) or there are too many connections to the
server. Check the server ip address and ask him to try another port.
Windows-firewalls while using an internet-connection
If a Windows-firewall is configured, it will block the ports and the TransData
connection. Therefore, an open port must exist. In order to open a port, you
can open the network settings and enter the network connections dialog. Select
the network connection you are using to access the internet, right click on
it and enter the Properties dialog. Click on the last tab to enter the extended
settings (for the firewall). If the checkbox for the firewall is checked, it
will block TransData connections. To enable connections, an open port must exist
- you can enable one by clicking "Settings" in this dialog.
Under the "Services" Tab, you can Add a new service and enable it.
Click "add", enter "TransData" as the service name, enter
"localhost" for the name or ip-address, and enter the port number
you are using for the external port number. Then, restart your internet connection,
check out the new ip-address (www.showmyip.com) and try to create a connection
using the selected port. Both server and client have to have opened the selected
port!
3) Chatting
If a connection between server and client is established, a chat message can be
transmitted by entering the message in the Chat-field and clicking "Send". Both
the client and the server can transmit messages, but the Server first has to select
the client from the client-list to whom he wants to speak. A server can talk to
all clients by clicking "Send to all clients". Client messages always go to the
server.
4) Transmitting files
Files can be sent from the server to a client and from a client to the server.
The computer receiving the file should first select a directory where incoming
files will be saved. This can be done by clicking "Choose target directory". To
send a file, select it by clicking "Choose file" and clicking "Send file". Note
that the user of the server application at first has to select the client to whom
the file should be sent to.
