Configuring the server

The isCOBOL Client listener requires that an isCOBOL Server has been started and is listening on the UNIX server machine. See Usage of isCOBOL Server for information about how to start the isCOBOL Server.

In addition, on the UNIX server machine the following environment variable must be set:

ISCOBOL_DISPLAY=X

This configuration assumes that the server machine has the program "xauth" installed; this program is installed on all the UNIX/Linux machines that have an X interface.

Note: In order for the above settings to work correctly, other X11 services must be turned off. Otherwise you may experience unexpected behaviors.

If the X interface it’s not present, save the following script in the file $HOME/.ssh/rc

if read proto cookie && [ -n "$DISPLAY" ] then dispnum=`echo $DISPLAY | sed 's/\(.*\:\)\([0-9]*\)\(.*\)/\2/'` echo unix:$dispnum $proto $cookie > $HOME/.iscobol_xauth_$dispnum fi
