[PHP] Users, groups, and permissions
I am using a Quadra Hosting Multi Domain (http://www.quadrahosting.com.au/) to host five different domains. As site owner I have FTP access to the root directory, and to everything underneath it. There is no domain directly attached to the root. Each domain has its own directory tree under the root directory, and I have a separate directory Engine containing the PHP code for all the sites. Each domain directory has a series of data files defining the various pages, optionally some configuration files, and a very short program index.php, which sets up a few user variables, and then passes control to the main program in Engine (by including it). The Engine processes a set of parameters, and from these generates the actual page which is passed to the user. The data files are almost entirely simple text files, and I do not use a database. The permissions are currently as they were set up by the provider. All directories in the system have permissions drwxr-xr-x, and all other files rw-r--r-- (when I read them as site owner -- I don't know if they are somehow changed when I access the site by downloading a page from one of the domains). I can load and run any of the files in Engine by including them into Index.php, and I can include images anywhere in the domain in the current page. I can also download them directly by quoting their full path. I can also show pages defined by data files in Engine, but I can neither show nor download images in Engine. I haven't tried accessing pages in other domains. As the permissions for group and others are the same for all directories, and all files, I don't understand how I can download images in the current domain, but not in Engine. Is it possible to reset the permissions so that different values are seen from different domains, and how can I tell which group I am actually in when I access a particular domain? Also is it possible to temporarily include a user in group, if they are not already there? Clancy. (The PHP manual has been down all day, and Google is not particularly helpful for this type of thing unless you already know the terminology, so I have largely been floundering in the dark. And when you look up 'user permissions' most books immediately assume database.) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Also protect >against SQL injection attacks by sanitizing your data and so forth. Thank you for your thoughtful suggestions. I totally agree. If someone goes sniffing, or the like, they might be able to get somewhat limited access to the domain. On the other hand if they can crack the FTP, and get into the master server, they can download the whole site. >Finally, view it as your responsibility to never store anything personal >or identifying (or in fact anything) on the client side in a cookie - >one simple key (session_id) in the cookie and everything on the safe >secure server is the way to go. I have thought of storing customising information for a particular user in a cookie, but it would simply consist of a set of parameter values. As they would be processed in exactly the same way as if they had been entered as parameters they would presumably represent no more, or less, threat than the parameters which are essential to the operation of the site (and which can readily be read, or bookmarked -- or, on reflection, experimented with). -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

BUT you have told me to use sessions, and sessions use a Cookie! If the Cookie I use contains random data, the only difference in security is in the time that it remains valid.

We have given you advice that you should NOT use Cookies in any fashion
to secure your site, but you remain steadfast that you know better --
so, what else can we say other than good luck.
tedd
These are my basic guidelines - what I like to do.
It may not be the best thing for every type od web site.
1) I have a user database that has username and a password hash. The
password itself is never stored.
The password hash is sha1sum(strtolower($username) . $salt . $password)
The salt is something like 5dgudsdgh5673g and should be stored as a
private variable in your user authentication class.
The reason I have the username there to is because some passwords are
very popular, using the username when generating the hash ensures that
two users with identical password will have different hashes. This is
important if an sql injection attack ever manages to get a dump of your
user database.
You should protect against sql injection by using prepared statements
for any database query that involves user submitted data (such as
username and password) but you still want to make sure that hashes are
unique, and you do that by adding the username to the salt.
When a user successfully logs in, the unique id of the user is then
stored as a session variable.
For administrative tasks, in addition to requiring that the user be
logged in to an account with admin privileges, all administrative tasks
are in a directory that is protected by apache authentication.
So to get to those kind of pages, the user has to have a
username/password that is stored in a .htpasswd file for Apache to let
them in AND they have to be logged in as a user that has been
authenticated as an administrative user.
I personally do all login via https so that username/password combos are
never sent plain text. That's more expensive because you need to
purchase a SSL certificate. You can use self-signed but it is better to
use an SSL certificate from a certificate authority.
For session security, I have the following directives set in my php.ini
file:
session.use_only_cookies = 1
- That prevents the session id from being sent via get.
session.cookie_lifetime = 0
- That instructs the browser to delete the cookie when the browsing
session ends.
session.cookie_httponly = 1
- That theoretically denies access to the cookie from scripting
languages. I say theoretically because when testing my site for XSS
security, I was initially able to get some XSS attacks to display my
session id (tested in firefox 2 w/o noscript - noscript blocked it even
with the domain allowed), so they were getting it somehow.
Since I have secure login which is a different domain from main domain,
in my web app itself I set
if (file_exists('/srv/path/DEVEL')) {
ini_set("session.cookie_domain",".mydomain.devel");
} else {
ini_set("session.cookie_domain",".mydomain.org");
}
That way, secure.mydomain.org (which is used for login) uses the same
session variable as www.mydomain.org (used for rest of site) so that
when the user logs in, the session variable that specifies the user on
the non secure domain gets updated when the user logs in on the secure
domain.
There are several good php books that discuss session security and php
web applications. I don't remember which books I used when learning my
technique, but it would be a good idea to buy or borrow some recent
books on php web application design.

In that case storing only the row id is will reduce the memory. If you are loading full row objects, it will take a lot of memory. But if you just load the row id values, it will significantly decrease the memory amount. Besides, You can load row ids in a chunk by chunk basis. if you have 10 millions of rows to process. load 1 rows as a chunk. process them then load the next chunk. This will significantly reduce memory usage. A good algorithm can solve your problem anytime. ;-) -- Shiplu Mokaddim My talks, http://talk.cmyweb.net Follow me, http://twitter.com/shiplu SUST Programmers, http://groups.google.com/group/p2psust Innovation distinguishes bet ... ...

[PHP] memory efficient hash table extension? like lchash ...
All, I'm loading millions of records into a backend PHP cli script that I need to build a hash index from to optimize key lookups for data that I'm importing into a MySQL database. The problem is that storing this data in a PHP array is not very memory efficient and my millions of records are consuming about 4-6 GB of ram. I have tried using some external key/value storage solutions like MemcacheDB, MongoDB, and straight MySQL, but none of these are fast enough for what I'm trying to do. Then I found the "lchash" extension for PHP and it looks like exactly what I want. It's a c-lib hash which is accessed from PHP. Using it would be slightly slower than using straight PHP arrays, but would be much more memory efficient since not all data needs to be stored as PHP zvals, etc. Problem is that the lchash extension can't ben installed in my PHP 5.3 build because "pecl install lchash" fails with a message about invalid checksum on the README file. Apparently this extension has been neglected and abandoned and hasn't been updated since 2005. Is there something like lchash that *is* being maintained? What would you all suggest? -- Dante -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

It appears the problem here is that your sessions are timing out too quickly, two simple approaches would be to boost the session lifetime to last longer OR create a quick (ajax) request every X minutes to keep the user logged in when inactive (which they may not want). To answer your specific questions though - what can be done to make this process more secure - no matter what approach you take, when working via http and needing logged in / secure functionality; you need the client to identify themselves with a key of some sort - no matter how you make the key it's always going to be passed via http (GET/POST/COOKIE) - if some "hacker" passes the same key then your system is going to think it's the original user and give them access. To make it trickier you can store information such as the users IP address, user agent string etc in session and compare it on each request; if it changes log the user out and destroy the session data - however your never going to protect against the most common form of "hacking", a nosy co-worker / person in the same house having a nosey while the user is at the toilet / making a brew. This is why many sites re-request password confirmation for potentially sensitive actions like transferring money, changing personal details and so forth (and send email confirmations to tell the user what changed - just in case). It must be pointed out though that non of this is worth even considering if you have sensitive ports (like ftp/ssh/mysql) open to the outside world as it's these back doors people will use to hack the whole server, not just one users personal account on a single site.

CacheMaxFileSize 128000
*CacheMinFileSize 100*
I commented that part, restarted Apache and bingo Instantly I had an 304
header.
What do I think the problem was? Whenever Apache received a request, it
handled it directly from _his_ cache and simply omitted what PHP was telling
him to do. The weird thing was that the class entered the 304 header part,
but Apache always ended up sending an 200 OK header and then the CSS. In
first place it shouldn't have sended the CSS because when I entered the 304
part, it should have died. It simply couldn't send any other output. (And
that was why I sniffered, if it shouldn't send the CSS; he must have been
send some kind of error, but my surprise was really big when I saw that the
raw data was just plain CSS, no other data was present).
Why was Apache then sending a 304 whenever the data was under the 100 byte
limit? Because he didn't have it in his cache and was obeying what PHP told
him to do. (This configuration created a cache whenever the file size is
between the 100 and 128000 bytes).
Anyway... now I will be publishing the class soon on phpclasses.org under
the BSD license. I'll work now on documentation and code cleanup but
whenever it is ready I will leave the link in this same list (if it is
allowed) xD
Greetings, a lot of thanks to Richard for his code and Rene for his
suggestion to take a look at Apache and good night :P (Despite being 7AM xD)

I doubt it will return the values in the order you have shown.

this call to next_result() seems strange.

the bit where you actually RTM or source?
you seem to be assuming what the fetch_array() call does,
not being able to tell exactly what kind of object $db
is I'll hazard a guess that fetch_array() is a wrapper method
for mysql_fetch_array() - you'd want mysql_fetch_assoc()
instead, and you'll need to loop to fetch all the rows.
maybe try something like:
echo "";
while ($yRow = $years->fetch_assoc())
print_r($yRow);
echo "";
