How to chat on Lan with IP Messenger (Local Network)

IP Messenger is one of the excellent tools which allows you to chat on LAN or network with other people if they are using the same software. The software can discover other users who are using it in the network and add them to the list. It displays the same name which one would have set when setting up their user profile in the software. Its an open-source, multi-platform messenger based on TCP/UDP. While there are tons of messenger services around, and you may not need it, but if you want to be off the social network and have your secret chat, this old tool still works.

  15. We have installed this s/w on all machines in LAN but it is not detecting all machines. only some machines it is showing. we have activated this on each machines.then what may be the problem?? please reply me immediately.

  16. My system shows 2 IP Addresses
    1) Main Windows XP system connected to LAN : IP starting with 10….
    2) Virtual Box Host-only Network : IP starting with 192……

    I am running windows XP system and i have a Sun VirtualBox installed on my system.

    My IPMsg on Windows is detecting VirtualBox IP instead of Windows XP IP-Address. Thus I am not able to see other system on my LAN.

    Can you please help me as how can i edit settings of IPMsg to detect Windows XP IP-adress ??


  17. Further to my above question, here i am adding a little more information :

    I seem to have nailed down the problem, but don’t know exactly how to resolve it for ipmsg.

    Since i have virtual box installed on my windows xp, so my system has now 2 networks. 1) Normal LAN network and 2)Network of VirtualBox.

    Both the networks have different IP Addresses
    Now ipmsg is detecting IPAddress of my VirtualBox Network and hence it is not able to detect other systems on my LAN network.

    Now can somebody help me to configure ipmsg such that it detect my LAN network rather than my VirtualBox Network ??

    Currently one work around is – i have to disable my VirtualBox network in order to make ipmsg work on my LAN Network

    I would be thankful if someone help me configure ipmsg to detect particular network only while there are more than 1 network connections on a system.

    Thank you,

  29. how to chat with another member with another IP address for example and

  30. IP msg is really great!
    But i hope to have one that can be used for Vista business and Windows 7

  31. If you have Virtual Host installed and your IPMSG is taking th Virtual Host IP address as the primary IP. Then you need to disable the Virtual Host network.

    This can be done from ‘My Network Places’ and disable the Virtual Host network. This should solve the problem.
