When I run this script on the server: > test.cgi, the test.txt file is
created. However when I use a browser as a client to execute the script, it
prints the $! OS_ERROR "Permission denied" and the test.txt file is not
created.
A key concept is that web servers typically run under a dedicated
username/ UID. For example, on Debian 5.0.3:
2009-10-10 11:05:31 dpchr...@p43400e ~
$ grep www-data /etc/passwd
www-data:x:33:33:www-data:/var/www:/bin/sh
If you don't care about security, you could grant world-write access to
your cgi-bin directory. If you have root access, another option could
be to configure the web server to run as your login UID.
If you do care about security, things get more complicated. If you just
want a simple test case to verify that you can run CGI scripts, a
"hello, world!" Perl/ CGI script follows FWIW.
HTH,
