Windows Firewall Issue

Hello,

Many times my customers write me after they have purchased program. Common reason is that some computers can send and receive note and some computer(s) can only send or only receive note. I always reply to my customers and write them to make sure that Windows Firewall settings are correct, meaning that ShixxNOTE program have opened default port 2000 for communication. So you can open default port 2000 or gave permission to ShixxNOTE program in Windows Firewall settings. This is always happening because when customer install program on a computer and then start program for the first time, Windows Firewall dialog prompts and they doesn’t know what to click on it.

So now I will put Windows Firewall images and what customer or simple 30-days trial user must click when program is installed and started first time on the computer. If you install program on Windows XP then you will get this dialog where you must click on the Unblock button like on an image below.

If you are installing ShixxNOTE on Windows 7 or Windows 10 you will get again Windows Firewall dialog where you must click on Allow Access button like on an image below.

If you do this at the program first start up you will have no problems later with sending or receiving notes.

Kind regards,

Windows Firewall and ShixxNOTE

If you have Windows Firewall activated on your computer and it is “On”, after ShixxNOTE program first start you will probably get Windows Security Alert dialog. If you have Windows 7 installed then you will get dialog (first picture above) asking you to allow access to ShixxNOTE program ; if you have Windows XP then dialog (second picture) will appear asking you to unblock program (check the picture above). This is normal because ShixxNOTE is multi-thread client/server application (LAN messenger). You can send note and receive notes to others in your LAN. For sending and receiving notes ShixxNOTE program communication port must be open. So if you get this dialog you have to click on Unblock or Allow access button to enable sending and receiving note(s) feature. After you click Allow access (Windows Vista/7) or Unblock (Windows XP) ShixxNOTE program will be added in Windows Firewall – Exceptions dialog and will work properly in your network.

If you have Windows 7 installed then you can open Windows Firewall with Advanced Security dialog and if you allowed access to program you will get dialog like picture bellow.

Windows 7 Firewall Advanced Settings

If you click Cancel or Keep Blocking button then you will not be able to receive notes from others. Because Windows Firewall will block incoming note data for ShixxNOTE program.

Also you can always open ShixxNOTE communication port “2000” manually in “Local area connections” – “Advanced tab”. If you don’t know how write me and I will help you.If you have any problems with sending or receiving notes in program, check your firewall settings first. If you didn’t fix the problem ask your network administrator to help you.

And finally write me if you have any problem regarding sending and receiving notes, or any other problems with program.

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.

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).
