+== 1.1 Installation, new version == #new
+The installation procedures have been significantly streamlined (e.g. to use apt). It is described in the [http://noxrepo.org/noxwiki/index.php/NOX_Installation NOX wiki], but it will be repeated here for completeness. 
+
+=== Base system ===
+NOX was built on an Ubuntu 10.10 server install with the following additions:
+ * packages: openssh-server ckermit git chromium-browser xinit icewm
+ * additional Ethernet interface (for !OpenFlow channel)
+ * no LVM 
+
+The switch is a NEC IP880/S3640 with !OpenFlow v 1.0 enabled firmware.  
+
+=== The process ===
+1. as root:
+{{{
+cd /etc/apt/sources.list.d
+sudo wget http://openflowswitch.org/downloads/debian/nox.list
+sudo apt-get update
+sudo apt-get install nox-dependencies
+}}} 
+
+2. add the following to the end of `/usr/lib/python2.6/dist-packages/twisted/internet/base.py`, before `__all__ = []` :
+{{{
+    def _handleSigchld(self, signum, frame,_threadSupport=platform.supportsThreads()):
+        from twisted.internet.process import reapAllProcesses
+        if _threadSupport:
+            self.callFromThread(reapAllProcesses)
+        else:
+            self.callLater(0, reapAllProcesses)
+}}}
+This is to make pyoxidereactor.py happy - it assumes that Python takes care of signal handling, which, in the newer versions, does not. The tabs should match with the rest of the file since Python is quite picky.

+3. download and build:
+{{{
+git clone git://noxrepo.org/nox
+cd nox
+./boot.sh
+mkdir build/
+cd build/
+../configure
+make -j 5
+}}}
+The install was done in /opt in this case.
