Thanks Blowtorch

Thanks for the reply Blowtorch,

I am still not clear about the answer though... Lets say someone broke into my garage and the files were not chmod'ed 666 or 777, (all files are 644 right now) are you saying that all they can do is look around and read files? But if the files were 666 or 777 they could do whatever they want to?

Are you also saying that it's possible to gain access to public_html (for instance) but not the root directories?

Ok, regarding my partner, he is not computer savvy but he knows a little HTML, SnippetMaster allows users to "edit LIVE html in the page" from their browser, you can define "snippet" areas within a page that are editable, there are different user levels where you can set different rights/areas that they can edit (it's actually very cool!) The user doesn't need to know; how to use FTP, how to upload or how to do other backend tasks, they just log-in and edit parts of a live page in a WYSIWYG editor within their browser. I use a lot of SSI, PHP, JS and CGI code on our web site and it's possible he could really mess things up if he has upload access.

Lastly, let me ask a question, should I absolutely not chmod 666 or 777 my .shtml and .html files? I guess I could chmod only the base html files that I include via SSI but that means a LOT more work for me...

Happy Holidays!

runit-init

runit-init(8)						      System Manager's Manual						     runit-init(8)

NAME

       init - a UNIX process no 1

SYNOPSIS

       init [ 0 | 6 ]

DESCRIPTION

       runit-init is the first process the kernel starts.  If runit-init is started as process no 1, it runs and replaces itself with runit(8).

       If runit-init is started while the system is up, it must be either called as init 0 or init 6:

       init 0 tells  the  Unix	process  no 1 to shutdown and halt the system.	To signal runit(8) the system halt request, runit-init removes all
	      permissions of the file /etc/runit/reboot (chmod 0), and sets the execute by owner permission of the file  /etc/runit/stopit  (chmod
	      100).  Then a CONT signal is sent to runit(8).

       init 6 tells  the  Unix	process no 1 to shutdown and reboot the system.  To signal runit(8) the system reboot request, runit-init sets the
	      execute by owner permission of the files /etc/runit/reboot and /etc/runit/stopit	(chmod	100).  Then  a	CONT  signal  is  sent	to
	      runit(8).

EXIT CODES

       runit-init returns 111 on error, 0 in all other cases.
