MiniEdit 2.2.0.1

UPDATE: You will not be able to run this specific version against the latest Mininet 2.2. There was a change in Mininet that removed a class that MiniEdit referenced. But there is good news. MiniEdit 2.2.0.1 has been included in the Mininet 2.2 distribution and has this bug fixed in it. So if you want MiniEdit that was released with Mininet 2.2, grab it from the link below.

Out with another update. As I mentioned in my last post, I’m going to start using new functions in Mininet that are not backward compatible with Mininet 2.1.0 or older. So to use this version, you will need to have the latest version of Mininet from GITHUB.

• Support TCP or SSL for remote controller
• Some UI layout changes in the host and switch properties.
• Support new Mininet HostWithPrivateDirs class. Allows you to mount private directories for each host which can also be mounted over an existing directory like /var/tmp or an application directory like /etc/httpd.  Another example is available in Mininet in https://github.com/mininet/mininet/blob/master/examples/bind.py.
• Replace custom code to set OF protocols with new Mininet OVSSwitch parameter. Below is an example of the new usage in Mininet.

s2 = net.addSwitch( 's2', protocols='OpenFlow13' )
or
s2 = net.addSwitch( 's2', protocols='OpenFlow13,OpenFlow11' )

MiniEdit 2.1.0.9

It’s been a little while since I published an update.  Here are a few enhancements and bug fixes.

• Export Script fixes
  • Link class was not getting set properly for TCLink
  • Now also exports the sFlow and NetFlow configuration you setup in MiniEdit
• Fix loading saved MiniEdit topologies JSON parsing problem.  Now parses properly back into Python
• Improve importTopo to support TCLink. Note that MiniEdit does not support all the TCLink parameters at this time.
  sudo ./miniedit-2.1.0.9.py –custom mytopo.py –topo mytopo –link tc
• Hosts and OF Switches now have text field for user defined shell command/script to run during node startup and shutdown.
  • Start and Stop commands are on the Host and OF switch properties.
  • The Start command is run after all nodes have started(net.start()).
  • The Stop command is the first thing run before the nodes are stopped (net.stop())

This will probably be the last release I make using the Mininet 2.1.0 code base.  My next release will be realigned to use the latest code from Mininet to pick up new features introduced after 2.1.0.

Hope everyone enjoys and is having a good summer so far.
