Hello I have read countless tutorials on the web about the issue of chmod on Unix-like computers.
Basicly you can set the permissions of a file or directory (by chmod'ing it) to control who can read, write and execute it.
A good explanation of this is here: http://www.phpdebutant.com/articles/CHMOD-777.php
What always seems to be lacking from any tutorial on chmod, that i have found, is exactly WHO is the 'user', 'group' or 'world'. (Or at least there are conflicting defintions.)
I have a website, which sits on the World Wide Web.
If i am right in believing many of these chmod articles - if i chmod 777 a file in the publicly accessable part of my server's file system (below my web root), this would mean that the World (or sometimes called 'All') can read, write and execute that file.
So, if i chmod a directory below my web root - does this mean that ANYONE can just upload files to it? or does 'World' in the chmod sense actually mean - anyone who has access to the inner workings of the machine that the file sits on?
So, in a chmod-sense who is World?
The reason why i'm trying to find this out is because i am about to use a dedicated server, which means that the only person who has access to the machine is me.
Therefore, should i worry about chmoding something to 777 in my document root, bearing in mind that i will be the only person who can FTP to the machine, login to the command shell, etc.?
I would appreciate any helpful definitive answers.
Notes about this question. Pre-empting some answers... In the tutorial i linked-to above it says that World includes websurfers. Yet, i find documentation of various PHP applications (which seem to be have been running well for years without problems) telling me to chmod 777 web-browsable folders as part of the installation process (and not saying to un-chmod it away from 777 after). See: http://fudforum.org/doc/d/manual.html#install.wizard.step1
So this kind of thing only confuses me more!

According to this article, MS Word does not support "custom" fonts which have been manipulated by a font program. I have a font I created in FontForge that I would like to use in MS Word. Does anyone know how Word can tell that a font is "custom" and if there is any way to override this? (I have Word 2004 for Mac.) -- 72.140.146.246 01:11, 19 October 2006 (UTC)
Firefox saves form information and makes suggestions when I type in a form field. The suggestions come in a kind of drop-down list. I know how to clear this list altogether, but what I want to do is clear some items from the list but not others. It's possible to do this in IE by highlighting the item and pressing Delete, but this doesn't work in Firefox. Any idea as to whether this can be done? Many thanks. -- Richardrj talk email 08:58, 19 October 2006 (UTC)
…what suggestions to put on the list? Sometimes, it seems to me that it is showing things I entered into other forms on a nearby page. — Bromskloss 10:20, 19 October 2006 (UTC)

Is there any program that could convert .wmv ( Windows Media Video) to .mov ( QuickTime)? I have a .wmv file, but I want to put it into my iTunes library, and iTunes isn't compatible with .wmv nor able to convert it like it can .wma. Any suggestions? — Akrabbim talk 15:18, 19 October 2006 (UTC)
Do Spybot and Ad-Aware do the same basic things? It seems to me that they do but I'm not sure... Dismas| (talk) 17:18, 19 October 2006 (UTC)
According to a PC World (no link sorry) article, it is best if you use them together. They do not interfere with each other. -- inky 07:18, 20 October 2006 (UTC)
On a website with frames you can have a menu.html for every page, and so if you want to change the menu you just change menu.html and it instantly updates on all "pages". However, without frames the menu is in the HTML for every page and so if you want to change the menu on every page you have to go through all the pages laboriously changing the menu. A friend of mine asked if there was a better way to do this, i.e. having a centralised menu that can be changed and updates on all pages immediately (using PHP or something?) and I honestly didn't know. So... is there? Sum0 18:21, 19 October 2006 (UTC)
Hi :-) I'd quite like to install Rockbox onto my iPod (4th generation, colour), but my iPod is HFS+ formatted, and I've been told that Rockbox only works on FAT32 iPods. I don't have a Windows computer handy, so is there any way I can FAT32 format my iPod with either Mac OS X Tiger or Ubuntu 6.06? Surely formatting it as an ordinary disk would stop the iPod firmware from working properly, and I the iPod updater (I think it's integrated into iTunes now) will only format iPods as HFS+. I think. Thanks :-) -- Saxsux 18:51, 19 October 2006 (UTC)
Hi all! I found nowhere else in the Net but here to ask this. I'm trying to download a 2.80 GB file through Azureus (from torrent.to). I was a few days ago at 180 Mb, but every few minutes, the file starts decreasing to less than that! I'm currently at... 2 Mb!!! Azureus says that it has discarded 24.XX MB, and Hash fails: 867 (1.67 GB)!! What am I doing wrong? Is it an Azureus problem? Is it a tracker problem? I'd already deleted a 1.38 GB file with the same problem... and I was at 80% already T-T! I have DHT disabled, but I have already downloaded other GB-size files before with the same configuration... Please HELP! Kreachure 23:45, 19 October 2006 (UTC)
Er, I don't quite get the difference between "downloaded total" and "complete"... the total size of the file is 2.80 Gb, and as of right now (*sobs*), it says: Downloaded: 0 Mb (24.87 Mb discarded)! (the discarded size seems to reset everytime I restart it, ao it might have discarded more before.) And, Hash fails: 898 (1.75 Gb)!!! I've had it going for about three days now (at 17k Down speed average)! Oh, by the way, there are 25 seeds, and 55 peers for the file right now... Do you think I should forget about this file for good? Or is there a way to check, uh, that CRC32 thingie you talk about? Again, if there is a better place to ask this, then please tell me. Thanks! Kreachure 04:05, 20 October 2006 (UTC)
Well, I think I'll try finding another torrent for the same thing, and see what happens. Thanks for trying to come up with a problem concerning the ISP or the router, but the Azureus settings are too technical for me to dare tinker around with them (and the wiki doesn't get friendlier either...) ! If the problem pops up again, I'll be more concise then. Thanks again, anyway!
