- invoke ofdatapath with --fail=closed (no controller = no connectivity!)
- stop hosts before switches before the controller
- this seems slightly more sensible
- it's the reverse of the startup order
- fix retry() so it kind of works (it's actually helpful I think!)
Not sure if I want nox_core -v in nox.py - it's useful for debugging.
ripcordtest.py (and grid.py) still depend on routing, which I haven't been
able to test yet.
Unfortunately, I can't test this at the moment since nox seems not to
be able to find the routing module.
Added/renamed examples: grid.py, tree1024.py
Added -v flag to nox arguments, so we have some chance of figuring
out why nox is dying, as it generally is.
Network may now be used with custom controllers.
An example of doing this is in nox.py, which instantiates at TreeNet
using a custom Controller, NoxController, that runs nox_core rather
than the reference controller.
low-level primitives.
The "nox.py" example attempts to use nox as a controller rather than
controller(8).
More edits for INSTALL and README, and refinements for sshd and xterm
examples.
Fixed xterm.py (and cleanup) to clean up screen sessions.
Cleaned up sshd.py (though interface is still in flux.)
Added 1024-node network example (treenet1024.py).
Added example showing multiple tests on a single network (multitest.py).
Renamed examples to make them easier to type!
(It also adds a route from the root namespace to the data network via
the first OpenFlow switch, so when you ssh in you go through OpenFlow!)
Modified Network() to optionally decouple starting the network, running
tests, and stopping the network. This allows multiple tests to be run
(or additional modifications to be made to the network before actually
starting the switches and controller.)
Still tweaking xterms - it sort of works but the screen sessions are not
cleaned up, which leads to nasty garbage.
