Comment on PHP Web Services - Authentication Based on Client’s IP by dimuthu

Hi Nabeel,
Thanks for the note.
I think I got what you are pointing out. Server possibly determine the source IP from the header of the IP packet, which can be easily regenerated with a fake source IP by some attacker.
Here I was answering to the problem asked in the forum http://wso2.org/forum/thread/4609, http://wso2.org/forum/thread/4659. I will mention your note in there too.

Thanks
Dimuthu

Comment on PHP Web Services - Authentication Based on Client’s IP by Nabeel

This comment is not directly related what you are pointing out in this entry. However, it may serve as a precautionary measure. In the absent of filtering at routers/firewalls, this method is vulnerable to IP spoofing attacks. Therefore, in such situations IP based authentication should not be used as a replacement to other authentication methods, such as WS-Sec username-token, but rather as a complement if the operation being protected is very sensitive.

Comment on XPath in SimpleXML by dimuthu

dimuthu — Mon, 22 Dec 2008 03:32:59 +0000

Hi vsp,
I think PHP still doesn’t have the full support for xpath 2.0 functions. Please try out ‘contains’ function instead of ‘matches’.

myxml->xpath(”//*[contains(@class,'classnm')]“)

Thanks

Does simplexml xpath support string functions described

I am trying to use them on attribute ‘class’
but they do not seem to work

for example
myxml->xpath(”//*[matches(@class,'classnm')]“)

does not work, PHP complains

Message: SimpleXMLElement::xpath() [simplexmlelement.xpath]: xmlXPathCompOpEval: function matches not found
