Provides an easy way for users to chat while they are all connected to a LAN network. It supports file sharing, message encryption, log viewer and desktop image capture and sharing.

IP Messenger is a pop-up messenger developed for multiple platforms by Shirozu Hiroaki.
It is a simple, light program which can be installed or run directly without any installation.
The program uses the TCP over IP or UDP to connect to the network.
The program is stand-alone and does not require any client-server mechanisms for the text and file transfer.
The first step is to use the settings screen and input the user name and the group name to start using the messenger. A messenger window pops-up with the message when there is a new message.
Some useful settings available from the Tray-Icon :
By checking the "None Popup Check" the messenger window does not pop-up but the tray-icon animates.
Checking the "No Recieve Sound" mutes the alert-sounds on new messages.
Check the "Default Sealed Check" to send private and secure messages which can be read only after the user unlocks his/her messenger with a password.
Files or folders can be just dragged into the messenger screen and transfered to the intended recipient.
The program does not show the File/Folder transfer progress to the sender and hence one should be careful to keep the computer switched on while the file transfer is in progress.
The messenger can also be used to communicate via the Internet.
This feature requires an Internet gateway with a Public IP or a valid domain (FQDN)
Firewall ports need to be unblocked for such a setup, an example connection would look like.
TCP FQDN/server :ms-wbt-server client_address_port:49441 ESTABLISHED
TCP client_address_port:49441 FQDN/server :ms-wbt-server ESTABLISHED

For use in offices with a large number of users, the list of members in the messenger can be sorted based on different groups. The messages sent and received can be logged to a file when configured. URLs can be opened directly (with a double-click) from the messenger without copying/pasting them into the browser address bar. The clickable URL can also be configured to open specific programs for different kinds of URLs.
More program options can be seen by right-clicking on the active task window, such as : Display Settings - Show Group, Host, IP Address and others and the sort options.
Fix Window positions, Size settings, Font settings and File/Folder transfer.
The size of the executable program is about 156K and occupies about 4 MB of memory when running.
The program does not release memory after a file transfer, resulting in a memory leak.
