Have you read the readmefile included in the source?
To start with you should rename all xxxx-dist.dat to xxxx.dat
Next thing is to copy lincardemu.dat to lincardemu.rc
Now make the necessary changes to your configuration in lincardemu.rc
After you are done you can try to start lce again....
cd into your lincardemu directory and type:
./lincardemu -r
-r means readonly-mode so that your conax.dat won´t be overwritten.
When starting without "-f lincardemu.dat" LCE will use lincardemu.rc as config file.
the lce window should pop up and you should see some startup and connection to the cardserver if you entered those details.
When you have the program running correctly it is time to install screen and a startscript soo you can run LCE as a service at startup.....very stable!
Are you using raspberry pi or TP-link wr703n or some other router?
Best regards
