Security and Firewall

ShixxNOTE 6.net is multi thread client (you can create note, write text and send note to others) and server (one program thread is always listening and waiting on default program port "2000" for incoming note) application. If you have program installed and you can send and receive note(s) normally then everything is OK, but if you have problems with communication, then check your firewall settings. Firewall programs like Zone Alarm or Windows Firewall will block all traffic for programs which are not in list.

For example if you install ShixxNOTE 6.net and you have Zone Alarm installed also, you will get message "ShixxNOTE is trying to act as server 127.0.0.0 will you allow it ?". This is normal, because ShixxNOTE is really server, so if you want to receive note(s) from others you must allow ShixxNOTE to act like server.

If you have Windows Firewall on, and you are having problems with sending or receiving note(s), you must open TCP port "2000" and name it for example "ShixxNOTE Port". If you block that port ShixxNOTE will not work properly, sending and receiving of note(s) will be blocked. If you ever get this dialog bellow you must click button "Unblock", then ShixxNOTE program will work properly and you don't need to open port manually.

Windows Firewall dialog on Windows XP where you must click Unblock button to enable sending and receiving notes If you don't know how to change network settings ask your network administrator for help. If some other application is using port "2000" you can change ShixxNOTE port on "Network Settings" dialog (right mouse click on ShixxNOTE tray icon located in your task bar and select "Settings" option).

In "Network Settings" dialog change port to some other if you need. But then all other computers in your LAN or Intranet which have program installed must do the same (change port to new one) to receive note(s).

If you have any problem or question regarding this article please write me on mail admin@shixxnote.com
