ConnectionType in Maple

The Maple interface connects to the kernel over a localhost connection. Normally, there is no problem. However, sometimes it is necessary to specify how Maple makes this connection.

1. Open a file manager, such as Windows Explorer or File Explorer (or Finder on Macintosh, or Files on Linux).

2. Locate the Maple initialization file. It is usually found here:

   C:\Users\%USERNAME%\AppData\Roaming\Maple\2019\Maple.ini (Windows)
   
   //Users/$USER/Library/Preferences/Maple/2019/Maple preferences (Macintosh)
   
   //home/$USER/.maple/2019/maplerc (Linux)

3. Open the file with the text editor of your choice. Just in case, you may want to run the program with administrative privileges.

4. Directly below the line starting "[Options]", add the following:

   ConnectionType=0
   

5. Save the file and test Maple.

6. If the problem still occurs, try "=1" instead of "=0". If this doesn't work, try "=2". If the problem still occurs, please contact support@maplesoft.com.

Note: If you don't have a "Maple.ini" (or similar preferences file, which is generated the first time Maple starts), you can create one yourself, with the same path and name as above, having the following content:

[Options]
ConnectionType=0
