* rc.local: /usr/bin/bash -> /bin/bash
bash is (and should be) located in /bin
this may have caused ubuntu 18.04 to not execute
/etc/rc.local and regenerate ssh keys
* fix bootAndRun()
This helps with virtualenv although it can open
up another security hole if you end up using an
unexpected python interpreter.
Overall it seems to make sense to err on the side
of usability but it's good to be aware of security.
However, for the remaining utility scripts that require
python 2, we explicitly note this with #!/usr/bin/python2.
This means that 'mn' will run be default in python3.
For python2, run
sudo python2 `which mn`
Also:
- change mn execution line to /usr/bin/python
(install seems to change it to python2 or python3)
- don't install python-is-python3 package
In certain cases, dp0 and its interfaces were not
being cleaned up, probably due to scratchnet.py being
killed before it terminated. This in turn caused the
natnet test to fail.
Ubuntu 20.04 fixes:
- fixes sshd test
- speeds up examples/{treeping64,tree1024}.py
- debugging hacks/output for testLinkChange
- removes cfs from examples/popen.py
- improves nat in nodelib (netplan fixes?)
- makes some tests executable
- waits for switches to connect in tests to
avoid race conditions
-- adds mn -w option and wait CLI command
Changes:
- REMOVES default "-v" argument for Controller()
and adds verbose(=False) option; avoiding logging
makes it faster
- CHANGES waitConnected to wait for 5 seconds
as documented; we may wish to implement an argument
to -w to set this timeout
Issues?
- There may still be an issue with the ovs-netplan-clean
service causing the boot to hang ;-(
* Install correctly on Ubuntu 20.04
Main changes are to avoid pulling in python2 by mistake, and then to make sure to install only python3 packages.
Also: Add net-tools which is needed to get ifconfig on newer Ubuntu releases.
(admin note: there are still a couple of remaining 20.04 issues but this is helpful)
