I strongly disagree with that.
Consider the following code (assuming $foo is 'external' variable):

1: if ($foo=='yes') transfer_money_to_me();

2: if ($_GET['foo']=='yes']) transfer_money_to_me();

Why (2) is safer than (1)? Answer: It is *not*.

As Rasmus has correctly pointed out, the usage of "register_globals=off"
per se cannot be considered a security measure. If you don't initialize
and/or check *all* user-supported variables, you're dead. It's as simple
as that. Is it annoying? Maybe. Is it necessary? *yes*

Anyway, IIRC the whole issue of register_globals started when some guy
presented a paper named "A Study in Scarlet". A whole lot of issues
where presented in that paper, which in my opinion, have been blown
quite out of perspective. register_globals is one of them.

Oh boy, this is starting to look like an urban myth : "-Hey do you know
that register_globals=on is bad? - Really? -Yeah, and you know what? It
allows the bad boys do vil things".

Re: [PHP] File download doesn't work with SSL

2002-10-07 Thread Rouvas Stathis


John,

problem is broken HTTP/1.1 implementation of Internet Exploder.
Make your server downgrade to HHTP/1.0.
e.g. for apache:




#
# The following directives modify normal HTTP response behavior.
# The first directive disables keepalive for Netscape 2.x and
browsers that
# spoof it. There are known problems with these browser
implementations.
# The second directive is for Microsoft Internet Explorer 4.0b2
# which has a broken HTTP/1.1 implementation and does not properly
# support keepalive when it is used on 301 or 302 (redirect)
responses.
#
BrowserMatch "Mozilla/2" nokeepalive
BrowserMatch "MSIE" nokeepalive downgrade-1.0 force-response-1.0

#
# The following directive disables HTTP/1.1 responses to browsers
which
# are in violation of the HTTP/1.0 spec by not being able to grok a
# basic 1.1 response.
#
BrowserMatch "RealPlayer 4\.0" force-response-1.0
BrowserMatch "Java/1\.0" force-response-1.0
BrowserMatch "JDK/1\.0" force-response-1.0




copy BrowserMatch line in SSL virtual server section too.

Re: [PHP] Need a Linux Guru!

2002-09-08 Thread Rouvas Stathis


Hi,

cd /etc/rc.d
locate the scripts reflecting the services you need to start at boot
do insserv for each script.
e.g.
insserv apache

That way, next time it boots these services will start.
Another way is to use the runtime-level editor of YaST2.

Yes, you could do that. But then again, what happens if you have to use
a piece of code that someone else has written that did not take the new
habbit into account? A number of interesting questions arise when you
have to operate that code alogn with newer one. Oh well, I guess
everything must change. After all, managing change is what we humans do,

It's just that I don't see any security value in superglobals. If
someone does not know enough, he/she will make the same mistake with or
without superglobals (from security's point of view).
As far as "lazy programming", please refer to my previous post.

Preventing namespace pollution...now you convince me.

I used the term "lazy programming" without explaining what I meant,
hence the misunderstanding. I refer to "lazy programming" in the sense
of not properly and thoroughly checking user input, or as I believe, any
input from external to you code sources. If you don't do that I don't
believe that anything will save you. Promoting superglobals as a
security enhanchment, no I don't buy that.

No, it isn't! For anything that breaks old functionality, 'forever' is

No it doesn't. It just provides another excuse for lazy programming.
Nothing will save a lazy programmer or one that doesn't understand basic

Re: [PHP] where i get .so [dll] file of linux ?

2002-03-29 Thread Rouvas Stathis


I always recompile PHP when I need a new module, but searching the
mailling list archives I found the following post by Rasmus that says
dl() in *nix is possible. Well, if Rasmus says it can be done, he is
propably true:-)

Exactly.  When you do ./configure --with-foo=shared; make
then modules/foo.so will appear magically and you can dl() that or load
it
using "extension=foo.so" in your php.ini.  You don't have to recompile
PHP.

Re: [PHP] Loading Images

2002-03-28 Thread Rouvas Stathis


As long as preventing users to download a picture you display, my .02Eu
opinion is that is is a fruitless task. A determined user will _always_
find a way to store the picture you send him. After all, you do send
data to him, therefore the data can be manipulated at will:-)

As far as some code to do it, see attached souce.
In the attached source, modify directories as needed.
Invoke with : php -q gif2function.php > test.php
Then point your browser to test.php.

warning: Select a dir with few images. If yopu want to know what happens
when you overdo it, goto
http://helios.mm.di.uoa.gr/~rouvas/giflib.php> to see what happened
to me!

In Linux you don't use dl(). Instead, you compile PHP with the modules
you need and they are there when you call them.

Re: AW: [PHP] Oracle question

2001-07-10 Thread Rouvas Stathis


PL/SQL code for an Oracle trigger that will auto-increment specified
field:


create or replace trigger 
before insert on 
for each row
begin
   if :new. is null then
  select .nextval into :new. from dual;
   end if;
end;

You have to create a sequence first. Example:

CREATE SEQUENCE 
 INCREMENT BY 1
 START WITH -99
 MAXVALUE 99
 MINVALUE -9
 CYCLE CACHE 5 ORDER;

Of course, replace values in  as needed.

If you use the aboce code verbatim, you will a field incrementing from
-9... until 9 and then it will begin all over again.

I do not use the CVS version, mainly because I do not know how to handle
CVS :-)
These are the lines from $PHPHOME/Zend/zend_alloc.c that I have.

It is indeed strange, since in the sources I have (downloaded about a
week ago), I already have the exact source that the patch presents
(without the lines prefixed with +).
I'm looking at $PHPHOME/Zend/zend_alloc.c file.

Am I to suppose that there is no need to patch anything?

Sure, if it works why bother? Still, isn't it nice the way configuration

Hi,

Been trying to compile PHP.4.0.6 with --with-zlib directive and failing.
Using --with-zlib-dir, however succeeds.

Does anyone knows the difference between the two ?

Also, in a related problem, if I try with --enable-xslt I get the
following results:

checking for XML support... yes
checking external libexpat install dir... no
checking whether to enable xslt support... yes
checking whether to enable the XSLT Sablotron backend... no
checking libexpat dir for Sablotron XSL support... no
configure: error: not found. Please re-install the  distribution

Do you experience any other sort of problems other than those warnings?
I mean, is anything wrong with the data? Normally, nothing should be
wrong.

I have seen the same messages (especially the "service handle not
intitialized" one) in my server too.
I have traced it to attemtps to close an already closed connection, as
in

$cone = OciLogon(...);
...stuff...
OciLogout($cone);
...stuff...
OciLogout($cone);

Other than filling the logs, there doesn't seem to be any other problem.
In my apps, everything works as it should.
I tend to simply ignore them:-)

Yes, I understand this.
But in my test case below, I never requested more than 50 connections to
oracle.
The problem is there even if you request 20 connections, provided that
you run the test script in quick succession and do not wait for the
oracle connections to die.

That is, if you:


while [-f file]; do
  ab -n 100 -c 20 
done


after a while you will get failed requests.

MaxClients 150, ensures that I do not run out of Apache childs and that
the failed requests are indeed due to ora conditions.

Thank you for your prompt reply.
I read your suggestion about MaxClients in Apache conf.
Since this is something I haven't thought before, I'll take it into
consideration first and then I will supply you a test case as you
requested.
I will do so in the forthcoming weekend.
Please, read below for my comments on your other points.

I am not aware of the internals, but the displayed behaviour when using
OciPLogon is exactly the same with the one displayed when you "forget"
to OciLogout.
I assume that a new connection is made, since I cannot find another
explanation for the number of open connections to increase.
I measure open connections doing "ps -elf | grep oracle | grep tnslsnr".

I don't think so. All connections to Oracle will close if left by

Test case (PHP script)
This code is typical of the way I handle connections to Oracle (except
that I use OciLogon instead of OciPLogon)

The above code runs in a separate window ("test-w") using the following
command:
ab -n 1000 -c 50 http://aspasia.mm.di.uoa.gr/~rouvas/testora.php

In another window (lets call it "monitor") the following runs in bash:

while [ -f afiedt.buf ]; do 
  echo -n httpd: `ps -elf | grep httpd | wc -l`;
  echo -en " "oracle: `ps -elf | grep oracle | wc -l`;
  uptime;
done

At the beginning, monitor displays something like:

httpd: 6 oracle: 15  1:50am  up 8 days,  5:38,  8 users,  load average:
1.33, 1.95, 3.49

>From now on, I will refer to "httpd: 6" and "oracle: 17" parts of the
above message as "httpd-counter" and "oracle-counter" respectively.

Let the test begin!

Everything is happening on the same machine.
Since I have not recorded all number I will show only significant ones,
that is those that caused troubles. The rest will be displayed as dashes
("-").

ab -n n1   -c n2   httpd-counter oracle-counter  Failed requests
  500 10-  -   0
  500 20-  -   0
  900 50- ~52  0 
The last did not cause any troubles, but... it took a long time for
these oracle processes to die.
So, I rerun the last invocation (900,50) three times serially, i.e. I
waited for the previous one to finish before I fired the next one.
  900 50- ~48  0
  900 50  ~67 many
  900 50  ~65 many
Next I fired up the following from three different windows
simultaneously (almost)

ab -n 1000 -c 50 

In the first run: http-counter: -
  oracle-counter  : (below 50)
  failed requests : (none)

I waited until http-counter:7 and oracle-counter:17 and rerun the three
simultaneous invocations.

httpd-counter   : -
oracle-counter  : 52
failed-requests : (none)

Without waiting, I fired the three invocations again.
httpd-counter  : 75 (max)
oracle-counter : 82 (max)
failed-requests: 550 (test-w-1), 544 (test-w-2) and 493 9 9(test-w-3)

After more runs (and to make a long story short), I observed that no
matter what the concurrency level or the number of requests to the ab
were, if oracle-counter reached about 55, no more requests would be
served.
That, of course, is consistent with the number of Oracle cursors
available.
What is not consistence, hence I think that OciPlogon is unsuitable in
its current implementation, is that while it proved extremely difficult
to run out of connections within a *single* invocation of my test script
with ab, it was trivial to do so when either (a) you invoke ab without
waiting enough time for the oracle-counter (number of Oracle processes)
to decrease or (b) you do parallel invocations.

Of course, (b) is to be expected. But I didn't expect (a).
If a small number of concurrency(10) is used, (a) is rather difficult to
achieve.
Almost any number bigger than that will raise the problem.

I would expect, that in (a) (serial invocations), PHP to reuse existing
connections and the oracle-counter to remain relatively constant.
Instead, it gradually increases, untill it reaches about 55, which in my
case, is the upper limit.

In real world scenarios, you don't have control over what is happening,
so you quickly run out of connections.

In favor of OciPLogon, I have to state that while with OciLogon I got 3
requests/second (max), using OciPlogon got me an impressive 42
requests/second (when no failed requests where observed).

My interpretation:
While PHP is running is doing a very good job of reusing active
connections.
When it is unloaded/stopped it "forgets" some of them and starts opening
some new ones.
That behaviour may be caused by Apache as some clients that were
originally spawned to handle the load, gradually die without killing the
oracle connections that have been associated with them. When a new
request is made, if an existing Apache client is able to handle it, the
connections associated with it are re-used. If a new one is spawned,
then a new set of connections is made.
Hence, the gradual increase of the oracle-counter.

About the same behaviour is observed when you "forget" to OciLogout,
which is to be expected.

PHP/Ora without persistent connections are fine and rock solid even
under heavy load.
PHP/Ora with persitent connections does not work.
Explanation.
Using OciPlogon you connect to Ora and everything is fine.
Then you issue an OciLogout and you terminate your connection as fas as
PHP is concerned. Unfortunately, the connection to Oracle is not closed,
as a "ps -ef | grep oracle" can tell you.
Next time PHP is called, OciPlogon requests (and gets) a new connection
to Oracle without using the old one or closing it. Then OciLogout is
called and you are now left with two open connections to Oracle.
The connections PHP opens will timeout eventually and close "by
themselves".
Now, if you are testing on a personal machine or your machine has enough
resources, this problem (that I call "lingering connections") may pass
unnoticed.
The moment you get more than about 10 hits, those "lingering
connections" will add up and pretty soon you will (a) run out of Ora
cursors or (b) run out of resources.
When that moment comes you will not be able to connect to Ora anymore,
untill some of those connections die, which of course is dependant on
the timeout.
Now in development server with 1GB of RAM
(Solaris/Ora.8.0.4.EE/PHP.4.0.3.pl1) the "lingering connections"
phenomenon rarely manifestated itself. In fact it was so rare that I
almost always suspected my code doing something nasty.
When it was moved into production (in a Suse
Linux.2.2.14/PHP.4.0.3.pl1/Ora.8.0.5.EE) with only 128MB of RAM, upon
the first test run it blew into my face.
After changing all OciPlogon into plain OciLogon, all problems
dissapeared.

This has happened with other applications that I have experimented with.
The "lingering connections" problem is with us at least since PHP.3.0.12
(which the first version of PHP I tried).

That's why I say that PHP/Ora with *persistent* connection do not play
well with each other.

I hoped I cleared the issue.
I really hope that this problem is resolved, since I expect an increase
in performance when the penalty for making a new connection is avoided.

Unfortunately, you are not doing anything wrong.
Persistent connections and PHP/Ora do not play well with each other.
I suggest that that you use plain OciLogon.

you can have access to everything, using the following construct:

window.document.forms[i].elements[j].name and
window.document.forms[i].elements[j].value

so, for example :






the first input text can be accessed as
window.document.forms[0].element[1] while the second can be accessed as
window.doucment.forms[0].elements[2]

In httpd.conf, in the  block for the site:



ForceType appllication/x-http-php



In a php program file, named ThisIsAProgram in the DocumentRoot of the

   }

Hit this URL:

http://whatever.site.com/ThisIsAProgram/these/directories/are/not/real


You should get:

Params[ 0 ] = 
Params[ 1 ] = these
Params[ 2 ] = directories
Params[ 3 ] = are
Params[ 4 ] = not
Params[ 5 ] = real

 

If you can't or don't want to do the  thing, you can name the
file ThisIsAProgram.php  (or .php3) and call it:


http://whatever.site.com/ThisIsAProgram.php/these/directories/are/not/re

But I think it is pretty cool to make the program name look like just
another directory in the tree, so I usually use .

Goto SquirrelMail  and search for the

If I remember correctly it has to do with IE not implementing correctly

Re: [PHP] PHP/Oracle mod

2001-02-13 Thread Rouvas Stathis


>From your mail, I understand that you cannot proceed past the
compilation step.
I've seen the same on previous versions of PHP for Linux, but now this
is solved.
Maybe the Solaris version didn't got the same fixes...
Anyway, PHP will look at ORACLE_HOME for the required libraries which
has now different semantics for Oracle.
Now(Ora.8i.later) ORACLE_BASE points to old (Ora.8.0.xx) ORACLE_HOME.
The new ORACLE_HOME should be $ORACLE_BASE/product/8.1.6 (or whatever
version you have).
Hope this helps.

Re: [PHP] What is "foo"?

And don't forget "goo". "foo" and "goo" go together:-)

Re: [PHP] Shared Memory with Yast-installed mod_php4 from SuSE.

2001-01-23 Thread Rouvas Stathis


Hit Thomas,

you need to recompile PHP with the options you want (as a shared apache
module) and then replace libphp4.so on /usr/lib/apache/ with your own
version.
A good thing is to keep SuSE's version as a backup:-)
Don't forget to restart apache afterwards. (/etc/rc.d/apache stop;
/etc/rc.d/apache start)

A SuSE.6.4 user.

Re: [PHP] Accessing Common Log Format (CLF) info.

You don't need to hach into anything.
Apache has builtin pipe redirection support.
Search for "rotatelog" in Apache docs.
