• How do I clone an OpenLDAP database

  - by elzapp

  I know this is more like a serverfault question than a stackoverflow question, but since serverfault isn't up yet, here I go: I'm supposed to move an application from one redhat server to another, and without very good knowledge of the internal workings of the application, how would I move the OpenLDAP database from the one machine to the other, with schemas and all. What files would I need to copy over? I believe the setup is pretty standard.

• On linux, how to check if port is in listen state without trying to connect.

  - by Daniel

  Hi, How do I check with C if a port on my local machine (if required by passing an IP or interface, too), is in listen state? I don't want to connect to this port for checking because I don't want to irritate the service behind this port. I want to use this to add the missing net.tcp.listen item to Zabbix.

  - by Spines

  If I call new Date() it will get the current time for the machine my app is running on. I'm assuming that the machines on the Google App Engine do not all have their time synchronized.

• PHP - Problem using file_get_contents

  - by shyam

  I have a problem while using the file_get_contents function. I am using it to get a response from a different web server, but it's not returning anything (shown as empty string using var_dump). Also, the problem is only while calling this specific server, because I got result when I used Google's address; and it's working fine in my local machine. I've tried cUrl too - but same result.

• Best way to send floating point numbers from .NET to Java and back

  - by Evgeny

  I'm writing a .NET application that will make an RPC call to a Java application (via a message queue). The data sent in both directions will be large arrays of floating-point numbers. What is the best way to serialize them to send them across the wire? I'd like something more compact than text, but architecture-independent as the server may not be an x86 machine. The Java application can be changed as needed.

• How can I gain root access on a Mac OS X system without wiping the OS?

  - by Richard T

  My father died recently and I've inherited his Mac. I'd love to put it to use in my own life, but I don't want to wipe its brains out just so I can reconfigure it to use in my network, etc. His old files are historically important to me—I trust you can understand my desire to keep them. I can log in as I had an account on the machine before he passed, but that's about it.

• How to determine whether or not a video format is supported

  - by Tal Even-Tov

  Hi, I've had to write an application that lists and plays tutorial videos along with accompanying text. It works well but since the videos are added by the user I need a way of checking to see whether or not a video can be played on the machine. I'm not sure whether or not there is an easy way to try test the file (and catch errors) or if I need to start looking at codecs installed. Does anybody have any experience with this?
