Serve the pages up with a small script that uses special, internal identifiers for each page. Why does the Minus World exist? On the other hand /home/mst3k is not accessible to the web server.

can only access publicly available file) for security. The default --suexec-userdir setting is public_html. The /var file system doesn't need to be large enough to accomodate web space (not a problem on most modern systems, but a headache in the old days). No local data should be owned by apache - the whole point of the apache user is to ensure that CGI scripts and the server in general have no special privileges
The umask is specified as a three-digit octal number indicating which permission bits should not be set; see the description of the umask(1) command for more details. But Linux gives us a way of controlling the resource allocation of each process, the parent process only has to set a new limit before starting the new process. In order to be as secure as possible, suexec is very careful about file permissions and ownership. I also recommend the newer fastcgi_ispcp.conf - since RC3 http://www.isp-control.net/ispcp/browser/trunk/configs/apache/fastcgi2.conf but this should not be the problem.
I strongly suggest that you test these permission settings on your web site. However, for it to work in .htaccess you'll need privileges. I've used AllowOverride all, but some lesser privileges may work. The only other approach I can think of is to abuse suEXEC's mod_userdir integration and somehow rewrite the requests to a user directory, but this is unlikely to work well.
This is correct: [anubis ~]$ id uid=54089(mst3k) gid=100(users) groups=48(apache),100(users),56410(cowboy) [anubis ~]$ Additional notes on suexec security ----------------------------------- As far as I know, your system is more secure if every user has Make the change via webmin or # the usermod command. Think VERY CAREFULLY about any checks you turn off and how their absense may be abused. | I want the script to run a | 'apache' which is what the web So what we did was to add chroot support to SuExec.
Do not use the page file name since hackers will substitute their own file name instead. navigate to this website You should not need # to edit this code for different users. If suexec is invoked by any other user, it assumes it's some sort of probing attempt and fails to execute (after logging the user mismatch). So SuExec does several checks before executing a script.

Common "exposures" with Perl CGI are: - backticks which exist to run commands and return stdout from those commands - the system() function which exists to run commands which will not We have currently implemented the following resource limits: CPU time limitations (RLIMIT_CPU) Maximum memory allocation by a process (RLIMIT_AS) Maximum size of files that a process may create (RLIMIT_FSIZE) Maximum number For an _internal_ web server (not internet facing) it may be sensible to turn off a lot of these checks - at my work place we have several of them disabled
I thought about this for a while. I cannot think of a reason that your scripts ever need to write a file in web accessible areas. share|improve this answer answered May 10 '12 at 23:47 mgorven 22.4k43790 Thanks mgorven. Document root is usally /var/www/html and is also web accessible.

If # you rewrite all requests (including those with a ~ then you'll have # a redirect loop.

You want CGI scripts to run with very few privileges, a bare minimum. Connect with top rated Experts 21 Experts available now in Live! The user apache should not have a login (and by default will not) and does not have a home directory. Simply disable suexec and force all CGI scripts to run as user apache (or in some configurations user "www").
