The list of subnets to route over VPN and the list of subnets to
exclude are parsed in option.py parse_subnetport(). Hostnames or IP
addresses are supported. If a hostname was provided, only the first IP
address was considered. This could result in some traffic not
traversing the VPN that the user might expect should traverse it from
the arguments passed to sshuttle.
This patch makes the function handle all of the IPs if a hostname is
provided. If a user provides a hostname with a CIDR mask, problems can
occur and we warn the user about the issue.
If the user includes a hostname with both an IPv4 and an IPv6 address,
and the underlying method doesn't support IPv6, then this patch will
cause sshuttle to fail. I plan to provide a future patch where failure
won't occur if the only place IPv6 addresses appear is in the exclude
list. In that case it should be safe to ignore the IPv6 address.
This patch also changes parse_ipport() which is used by the --to-ns
option. If the user provides a hostname here, we just use the first IP
from the hostname and warn the user that only one is being used.
Some bug reports include verbose sshuttle output but lack the version
that is being used. Including the sshuttle version in the output may
make it easier to handle future bug reports.
Improve detection of when the ssh process exits in both daemon and
foreground modes. Previously, sshuttle could infinite loop with 100%
cpu usage if the ssh process died. On machines that use suspend, the
ssh connection might not resume after wakeup. Now, this situation is
detected and sshuttle exits. The fix involves changing the return
value we check for when we call poll() and using a psutil function to
detect when the process exits if we are running sshuttle as a daemon.
Python2 ignores the byte string qualification (b’foo’) but falls over for the combination rb for this regexp. Switching the qualification to br appears to fix this and works in both python2 and python3.
Fixes #469. We replace python3 exclusive code with a check for python3 and a compatibility fix. Note that the switch from os.set_nonblocking to fcntl.fcntl in 98d052d (fixing #503) also fixes python2 compatibility.

* Make hostwatch locale-independent
See #377: hostwatch used to call netstat and parse the result,
without setting the locale.
The problem is converting the binary output to a unicode string,
as the locale may be utf-8, latin-1, or literally anything.
Setting the locale to C avoids this issue, as netstat's source
strings to not use non-ASCII characters.
* Break line, check all other invocations
This commit resolves#297, allowing the buffers used in the latency control to be changed with a command line option ‘--latency-buffer-size’.
We do this by changing a module variable in ssnet.py (similar to the MAX_CHANNEL variable) which seems to be the simplest code change without extensive hacking.
Documentation is also updated.
The changes in a765aa32 removed a more complex pieced of code for parsing which sudo command to use. The %(eb)s no longer refers to any variable and is directly printed to the command line.
%(eb)s is now replaced with ‘sudo’.
Regression was introduced in #337 that is skipping all local traffic,
including DNS. This change makes UDP port 53 (DNS) LOCAL traffic to be
treated as special case.
Fixes#357
