apply ANS group patches.

Patches allow to use specific per-link delay distributions, and to assign deterministic IP address to TCIntf interfaces.
Patches also add a "deb" target to the Makefile in order to create the debian package.

Add error message to shed light on why this sometimes fails

Only use 80 hosts for linearbandwidth.py for now

In the long run, we should debug the performance issues
with kvm and Ubuntu 15. For now, however, we're relaxing
the constraints.

Closes #594

5dc15aea 01/26/2016 11:40 PM Bob Lantz

Tolerate slow startup/lost pings for now

In the long run we should troubleshoot the performance issue
on kvm/Ubuntu15, but for now we are relaxing the constraint.

Closes #593

Use ifconfig for interface verification.

Previously we were using both ip link and ifconfig - not only is
this inconsistent and redundant, but it also broke when newer
ip link changed the reported names of certain interfacs to
"h1-eth0@36:".

Fixes #592

vm_clean: delete keys from from /etc/ssh/ before shipping vm

It's a bad idea for all Mininet VMs to share the same SSH keys.
Certainly users can regenerate their own keys, but it's better
if we don't ship a key and simply regenerate it on boot.

Collect all server output in iperf()

This still isn't ideal - this was breaking UDP iperf, which
can take a bit of time to print its output after you control-c it.

5365831d 01/22/2016 01:07 AM Bob Lantz

Use 0% loss when testing examples/simpleperf.py

Also clarified the code in test_simpleperf.py.

Fix UDP iperf.

c0793cb5 01/21/2016 01:33 AM Bob Lantz

Add "run" alias for "use" and integrate build/test options

Keeping "use" for now even though it seems harder to remember
than "run". And the build/test options are probably much
clearer being inline in the help.

327af97c 01/21/2016 01:32 AM Bob Lantz

Try to fix iperf race condition

This is more complicated than it should be. We are also relying on
the fact that waitOutput should eat extra prompts most of the time.
Still not perfect - it's hard to get this exactly right, and we
should try to make it easier!...

b78b99b6 01/20/2016 09:33 PM Bob Lantz

monitor() should return on timeout; docstring changes

It appears that read() has been blocking for some time,
so for now it makes sense to change the documentation to
match the functionality!

It's not entirely clear if monitor() expects this functionality....

I'm not sure whether we really need to turn off ip_forward before
flushing iptables, but it might possibly be useful to avoid certain
unexpected behavior.

Enable NAT to use all interfaces.

Also put the net.ipv4.ip_forward option back to what it was before on exit,
rather than always setting back to 0.

Simply use class names as option help

The justification for this is that 1) the options are
already documented in the API documentation and 2) the
class names are fairly self-explanatory, so adding short
descriptions doesn't add much.

In the future, however, we could add a short description...
