Windows Server uses uses TCP syn cookies to protect itself from syn-flooding attacks.
Is it known, how the operating system (Windows Server 2008 R2 and Windows Server 2012) calculates the syn cookie? If so, how is the calculation done?
One of my clients is running an Exchange Server 2010 in their company. On this server, a public address book folder is stored, which can be accessed and edited by various people.
Now, since there is a problem with the integrity of the contact records, they asked for a solution to enforce some rules when contacts are created. For example the first name, company name and phone number fields have to be filled.
Since I am only moderately experienced with Exchange (I'm a developer) I'm asking for your help: Is there a way to set such a kind of constraint in Exchange? If not, could it be possible to enforce this rules on client side (with a custom outlook plugin or a macro)?
thanks for any help, Emi
I am currently testing a new Mindtouch installation on a Debian web server.
When using the Math-extension (a extension which uses LaTeX to convert mathematical formulas into .png images and shows them on the web-page), I simply receive no output from the math extension (not even an error message).
I was digging deeper into the problem, I noticed that the following HTML code is send from the server to the client where the image of the formula should be:
<img src="local://7c81b24bae6310e118b6b59b095eff15/deki/services/default/17/images/07adeb54-461a-d4c1-f66a-a69d14e29c2f.png" />
I have no idea what the problem could be here, since there are also no indications of any errors in the access, error or deki-api log. The error is also not reproducible on my local system with the same configuration steps done.
with best regards, emiswelt
EDIT:
As advised, I searched through the mindtouch forums, and woha, here is the solution: http://forums.developer.mindtouch.com/showthread.php?t=8112&highlight=math+local
I am currently configuring Quagga. Quagga is an routing suite for Linux. I was suggested to use --disable-zebra when configuring Quagga (./configure --disable-zebra). Does anyone exactly know what this command does?
