[PHP] Checking Client's Cipher Strength with IIS

[Ed Gorski]

Hello, 

I have a question who's answer has been bugging me for a while.  What I need
to do is write a script that detects if a browser is using 128-bit
encryption when connecting to our website.  While this is easy for most (I
have the script working for them), a real problem for me has come up with
clients that run IE on Windows 2K without 128-bit support (ie 40-bit or 56
instead).  Do any of you fine ladies and gentlemen know how to detect a
browser's cipher strength using PHP (or any other web language)?  I am
running PHP 4.3.1 on IIS 5.0 on a Windows 2000 server.  I have tried using
some server vars (namely HTTPS_KEYSIZE) but that reports incorrect data with
the win2k/IE/56-bit configuration I mentioned above.

Any help is appreciated and thanks in advance,

Ed

RE: [PHP] php session not persisting

[Ed Gorski]

Do you have cookies enabled on your browser?  If not then you will need to
make sure that you compile or change your php.ini to reflect that (ie with
trans-sid).

It's best to state the specific version of PHP you're using rather than just

'latest' (as it could mean different things to different people at different

times).

If you're using PHP > 4.1.0 then you ought to be using $_SESSION for all
your 
session needs -- see manual for examples.

Couple of clarifications Dale:

Is this an internal intranet server?  Can it be?
Do you have admin rights to the server?
What's OS and Server are you running?

I have the following scenario:

I have this timeclock program that my employees access by logging into and
the program pretty much allows them to clock-in and clock-out. The problem
is that I noticed some of the employees were clocking-in and clocking-out
from their home. The main problem is that the machine at work that the
employees use to access this program does not have a static ip address. Is
there any way to access the mac address in php.

Any ideas?

thanks,
Dale

RE: [PHP] Registered sessions.

[Ed Gorski]

You need to append the session name and id to the header location everytime
you redirect that way.  So your header redirect should read:

header('Location: researchpapers2.php?'.session_name().'='.session_id());

When you have normal links to other pages you don't have to do this but on
header redirects like the one above you do.

Hope this helps,

Hi, 

I have a php page that validates if a username and password are valid. if
they are the php page registers and assignes a session variable a value.
Then straight after that it automatically calls then next php page using the

 header("Location: researchpapers2.php"); command. My question is: does the
session variable still get passed to the researchpapers2.php page, with the
header command? because it doesnt seem to receive a session variable. any
advice as to where i am going wrong???

thanx Angelo.

RE: [PHP] Sessions and headers

[Ed Gorski]

Well you are partly right Chris.  But the client automatically sends the
cookie with the HTTP request.  IE your request for a cookie doesn't send a
separate request header to the client.

You might want to check to see if you are accidentally outputting something
else after you call session_start() (or before).  I did something similar to
what you are describing.  I have the user log on, the php creates a file and
prompts them to download.  On the download page I check the session before I
output anything and it works fine for me.  Can you paste a bit of the
non-functioning source code so that we can see the problem more clearly?

Subject: [PHP] Sessions and headers


When using PHP sessions, if the user's browser supports
cookies, PHP sets the session id as a cookie (so far as I
understand it).  So when trying to use the session ID in a 
script, a cookie request is sent to the browser to get the ID
and assigns it to the internal variable $PHPSESSID (again,
so far as I understand it).
My problem is this and I'm hoping someone has come up
with a workaround...
When I try to use the Header() function call (which I do alot
to set the content type such as PDF, doc, xl, etc), I'm getting
errors opening up the file due to previous headers already 
having been sent - namely, the header call to get the cookie
value.
This problem prevents me from using sessions in scripts I
write to output and open up Word, Acrobat, Excel, etc. and 
I am finding that to be an increasing problem as it requires
that I come up with a different way to access the session
data and open the script up to vulnerabilities.
I've tried using ob_start() and ob_end_clean() before and
after the session calls hoping that it might somehow solve
my problem but it doesn't.
Has anyone else come up against this problem?  Have you
found a workaround other than come up with a different way
to do the same thing as code you already have and use to
access session data?

thnx,
Chris

> What errors, exactly? Can you show some examples?

The errors are not PHP.  They are from the browser trying to open the 
data being sent from the server (the HTML or binary data) in the appropriate
program.  eg, Acrobat for PDF, Word for DOC, Excel for XL.
For this particular case, I'm using the following header call:

header( "Content-Type: application/pdf" );

and I'm following it up with PDF binary data.  As everyone well knows, this
will cause Acrobat to start up and the data displayed therein.  Well, if any
headers are sent to the browser prior to the above header() call, the app 
fails to load up and your browser gives you an error.  In this case, the
error
I am getting is as follows:

"Internet explorer cannot download YOURFILENAME
Internet Explorer was not able to open this Internet site.  The requested 
site is either unavailable or cannot be found.  Please try again later."

The offending function call that causes all this grief is "session_start()".
When I comment out the call to session_start(), the PDF opens up just
fine.  When I leave the function call in, I get the above error.
(And a quick note, I have trans-sid enabled)
Since you need session_start() to start or resume a session and since
that function call messes with any subsequent header() calls, I've not
been able to use sessions in scripts that output data to Word, Acrobat,
Excel, etc. and I need to do something about that.

It's a browser error I'm getting.  And I get this problem on all browsers.

Try including "session_cache_limiter('public');" before your

No the parser sees the ?> after a // because it needs to see when to quit

No, if you use /* ? */ as a comment the parser will skip right over

 From my experience the PHP parser acts much like the HTML parser in the

RE: [PHP] Intermediate "Searching..." screen.

[Ed Gorski]

Well if you just wanted to do a simple redirect like the one you describe 
just use meta tags in the 



If you use the method that Scott details (I would try to avoid that one 
though), create an HTML "Searching..." page with this meta tag.  In the 
"searchPage.php" file have a redirect to another page after the search is 
completethis technique is REALLY useful if you have a page call a 
script that takes a long time to execute but doesn't really return anything 
to the page (ie send a bunch of e-mails, calculate averages and store in a 
db, etc).

Re: [PHP] Thread safe

[Ed Gorski]

Yeah but if you get a higher load of users that can get REALLY uglyif 
it is strictly an update (editing of an already existing element) then 
locking that record should be fine but if it's an insert or delete you 
shouldn't lock the table.

Re: [PHP] .php extension

Yeah one of the simple tricks to mask that you use php is to make the 
extention that the PHP Parser looks for (ie name it page.foo) or whatever 
and have:

AddType application/x-httpd-php .foo

RE: [PHP] PHP new super globals or something else??

Well you should be using $_GET, $_POST and $_SESSION and turn 
register-globlals off as of PHP 4.2.1.I think you need to keep 
track-vars on for these arrays to be initialized.

Yes you really need to indicate what version of php you are using, what 
server you are using and what db you are using if you ever need to ask for

SQL SERVER
mssql_connect()

Inside php.ini there is a setting to turn "Magic Quotes" on or off.turn 
them off and you won't have this problem.  If you don't have access to the

Re: [PHP] sessions and 'normal practice'

[Ed Gorski]

1. This is done for users that don't use cookies.  Believe it or not but 
there are people out there that are afraid of cookies and automatically 
turn them off.  Without  appending the sessionid to the end of the URL, 
sessions won't work for these people.  Now how does your host append to the 
end of each URL?  Do they do it manually in the code or do they use the 
SID?  An easy way to test for this is to fire up a browser with cookies 
enabled and see if the sessionid gets appended to  each url.  If so tell 
them to use the SID constant.  Let me know and I can help you further

Re: [PHP] sessions and 'normal practice'

[Ed Gorski]

Well that must mean that they are using session_name() and session_id().  I 
really don't know why they are using that (considering it'll add 
unnecessary overhead of calling session_name(),session_id() twice).  My 
guess is that they don't have a clue about the SID constant that 
automatically gets generated as "PHPSESSIONID=dsfgsdgsdfgsgsdfg" if the 
browser does not accept cookies and is empty otherwise.  I bet they are a 
bunch of asp developers ;-)

Re: [PHP] your philosophy on php-design

well just have the "add to basket" link on index.php call add_to_basket.php 
which doesn't print out anything and redirect back to 
index.php?type=itemAdded when finished.

On index.php you can check for $_GET['type'] and generate the appropriate 
table.
