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.
Just because we may have found IPv6 DNS servers from /etc/resolv.conf
doesn't mean we should force IPv6 support.
Instead we should disable the IPv6 DNS servers if IPv6 is disabled.
Note: this will also result in any IPv6 servers specified on the command
line being silently ignored too.
Specifying an IPv6 subnet will still require IPv6 support.
Closes#74
In some cases (see #43) it seems that some network configurations may
end up setting a skip on lo. As sshuttle adds rules that rely on
filtering/translating packets on lo, this causes problem. This fix
overrides the skip and makes the rules be applied again.
Should fix at least some of the problems reported on #43.
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.
Wew were trying to allocate an IPv6 socket even though we weren't using
IPv6, causing failures on systems without IPv6 support available.
This change means a number of methods on MultiListener, e.g. setsockopt,
should not be called until after the bind call.
Closes#68
