Bob Lantz 2ceb57915a Merge branch 'cdburkard-patches/test_walkthrough' 2014-10-07 16:11:03 -07:00
Bob Lantz 61c144b9f6 Minor fixes to wireshark test 2014-10-07 16:08:57 -07:00
lantz 8537e8d9fa Merge pull request #404 from cdburkard/patches/default_cli 
use node.pexec() to update IP address of intf instead of node.cmd()
 2014-10-07 14:27:46 -07:00
Bob Lantz 098bede0ec Wait for controller shutdown. 
Unfortunately, this can slow things down a bit - perhaps
100-200 ms in the case of ovs-controller, but I am hoping that
it may help slightly with #399.

Bob Lantz ded25a9ef8 disableNtpd: wait 1 second and print out date just to be sure 2014-10-01 14:42:43 -07:00
Bob Lantz 1bae1aab03 Turn of ntpd and set date manually before tests 
This should fix the problem where we see the first test
taking negative time, as well as possibly other issues
with performance tests which may be sensitive to changes
in wall clock time.

Fixes #398

 2014-09-29 17:41:07 -07:00
Bob Lantz ec26c7492d Install vconfig in VM for VLAN example 
This should help with #393 although it doesn't solve
the root issue of the example failing silently when
vconfig is missing.

Bob Lantz 61760eabc5 Make sure we 'sudo kill' our sudo pexpect process in close(). 
This should more reliably shut down pexpect subprocesses when
build.py exits before completion.

 2014-09-23 14:09:02 -07:00
Bob Lantz f603052b35 Install coloring rules regardless of plugin. Also don't clobber. 2014-09-23 14:01:40 -07:00
Bob Lantz 47be38e63c Don't install lua plugin for wireshark 1.12+ 
Apparently there is a conflict where the lua plugin
conflicts with the built-in dissector for openflow
that is included with 1.12 and up. For now, we will
just not install the plugin. This should fix the
14.10 VM build.

Additionally, I have added a handy function,
version_ge, which compares version numbers in
canonical x.y.z format. Thanks to stackoverflow for
pointing out the incredibly useful sort -V option!
 2014-09-23 13:45:20 -07:00
Bob Lantz 9ca775cba3 Switch to loxigen-built openflow.lua wireshark plugin 
The older wireshark dissectors were not well-maintained
and were a pain to build. They also added tons of extra junk
into our VM images! The ones built into the current
wireshark are deficient for 1.3. The solution for the
future is almost certainly to go with the lua-based plugin,
since it is architecture-independent and should be much
easier to maintain and upgrade.

Bob Lantz c265deedef Cluster edition prototype: remote nodes and links. 
We add a new experimental feature to allow Mininet to run across
a cluster of machines. This is currently implemented via a set
mix-in classes that provide remote nodes that are implemented
via a connection to a remote shell, and remote links which are
tunnels across servers. In this preliminary implementation,
both control and data connections are made via ssh, but this
could change in the future.

A MininetCluster class is provided which allows existing code
to be used with minimal modification - all that is required is
to provide a list of servers to use. A customizable placement
algorithm may also be specified. An experimental CLI subclass
is also provided to make it easier to examine node placement;
status and links commands can also check whether nodes and
tunnels are still running.

Although this is an experimental feature, it does include a
--cluster option to make it convenient to start up a Mininet
simulation over a cluster, and a script to assist with setting
up the prerequisite authentication via ssh key pairs.

The cluster feature is preliminary and missing some obvious
important features, such as parallel startup and multiple tunnel
types, which we hope to add in the future.

Bob Lantz b85943dc0a chdir() to correct path after calling chroot()
