This should fix an issue introduced in #117 where when no subnets are
given via file (-s file) the variable is None instead of an empty list
and the concatenation with the subnets given as positional parameters
fails.
By just splitting at spaces, multi-word arguments are torn apart even if
quoted. In case of custom ssh-cmd, this makes it practically impossible
to set certian options through `ssh -o`.
shlex splits arguments like a shell and e.g. respects quotes.
This should fix#116. Handling this while still having the positional
arguments and -s both write to the same list turned out to be more
complicated than it's worth so each writes to their own variable and we
merge them at the end.
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).
We shouldn't come up with a fatal error because of a ENETUNREACH when
trying to contact the DNS server. Although this error shouldn't happen
either.
Fixes#89.
Sometime ago I was in python mode and incorrectly indented a line of the
shell script with spaces instead of tabs. Shame on me. This should bring
things back to their natural order.
Previously the sshuttle shell script would pass the python to use as the
first argument of the command. The new run script no longer does this.
Instead we can obtain the python being used via sys.executable.
Fixes#88.
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.
When passing multiple subnet files, e.g., by using -s/--subnets
multiple times or by using it together with subnets passed as positional
arguments append the content from all sources instead of only using the
subnets from the last source. This makes the behaviour of -s/--subnets
consistent with -x/--exclude.
This allows disabling all client tests using a conftest.py file, if for
example #56 gets merged and the server supports more python versions
then the server.
The server side tests are very incomplete.
In situations where 2.7 is available and some unsupported 3.x is the
system's default we should probably fallback to 2.7 instead of the
default (that might be e.g. 3.4). This might fix#78.
