Hi, thanx for your answer.
the program I want to call is a biological one (I am studying biology), that can be installed and ran locally on a UNIX machine.
I have installed it as root user and I have checked that it can also be ran in my home directory, without having to call it from the full path.
However, I tried calling it like /usr/local/bin/hmmpfam (hmmpfam is the name of the program), but again no luck.
What I can only think about has to do with Apache. I mean that, the documents I use are stored in /srv/www/htdocs.
I think that when you ran something in your webserver, this is executed as wwwrun user, right?
do you think I must somehow grant privileges to this user specifically ?
(I just want to note that the html or other files in the htdocs/ directory are functioning correctly. Only that problem with the external program is not executed...)
