* re-organized imports according to pep8
* fixed all remaining pep8 issues
* moved common config into setup.cfg, additionally test `tests`
* removed --select=X -- the errors selected where by default not in
flake8's --ignore list so effectively had no effect
* update .travis.yml to reflect changes in tox.ini
* make travis just use tox in order to avoid code duplaction
* replace py.test with pytest
* fixed .travis.yml
* try different pypy toxenv
* hopefully fixed testenv for pypy
* added pypy basepython, removed unused python2.6
* install dev package before testing (fixes missing coverage)
* fixed empty exception pass blocks with noqa
* Added dummy log message on empty try-except-pass blocks to make dodacy happy :(
* Replaced Exception with BaseException
There's a known issue that makes sshuttle crash if there are too
many routes on the remote host (that don't fit in 64KB). This patch
requests the routes only if auto-nets is specified on the command
line.
When I starting sshuttle with option `--seed-hosts example.com`, got the following error:
```
hostwatch: Starting hostwatch with Python version 3.5.2

It seems like the list of hosts is not properly decoded on the server side. This is an attempt to fix that.
While with AF_INET sockaddr is a 2-tuple composed by (address, port),
with AF_INET6 it is a 4-tuple with (address, port, flow info, scope id).
We were always passing a 2-tuple to socket.connect which would fail whenever
the address was, for instance, a link-local IPv6 address that needs a scope id.
With this change we now use getaddrinfo to correctly compute the full tuple.
Fixes#156.
netstat outputs some headers in BSD (that the Linux version does not)
that are not tabular and were breaking our 'split line into columns
and get nth column' logic. We now skip such headers.
Should fix#141.
`netstat` has been deprecated for some time and some distros might
start shipping without it in the near future. This commit adds support
for `ip route` and uses it when available.
AF_INET is the same constant on Linux and BSD but AF_INET6
is different. As the client and server can be running on
different platforms we can not just set the socket family
to what comes in the wire.
A possible implementation for the change requested in #94, so that seed
hosts can be used without auto hosts. In this scenario only the
specified hosts (or ips) will be looked up (or rev looked up).
It is often the case that the user has no administrative control over
the server that is being used. As such it is important to support as
many versions as possible, at least on the remote server end. These
fixes will allow sshuttle to be used with servers that have only
python 2.4 or python 2.6 installed while hopefully not breaking the
compatibility with 2.7 and 3.5.
This is the error message that this commit fixes:
TypeError: sequence item 142: expected a bytes-like object, str found
Complete what 1c46f25e started, more or less.
