I have an observation. It appears that the vshell.conf file now must be copied/moved from "/usr/local/vshell" to "/etc" folder otherwise an ugly error appears when trying to use the /vshell application. The error states: Unable to open '' file!
The "error" is due to a modification done in the /usr/local/vshell/constants.inc.php file that now requires to have this file in the /etc folder
// Switch to use external configuration file by Tony Yarusso, 30 March 2011
$ini_array = parse_ini_file("/etc/vshell.conf");
Once the vshell.conf is copied to the folder /etc, the /vshell application works like a charm. Unfortunately, it is not documented since it was done very recently
