* Add support to run inside Linux namespace **Motivation:** In a specific use case, we use sshuttle to provide access to private networks from multiple sites to a specific host. The sites may contain networks that overlap each other, so each site is accessed inside a different namespace that provides process-level network isolation and prevents network overlap. **Objective:** This commit just adds a convenient way of spawning multiple sshuttle instances inside different namespaces from a single process, by passing the namespace's name though the variable --namespace. The result is the same as calling `ip netns exec $NAMESPACE sshuttle ...` * Add the argument --namespace-pid The argument '--namespace-pid' allows sshuttle to attach to the same net namespace used by a running process. * PEP-8 compliance * Add comment * Make --namespace and --namespace-pid mutually exclusive. * Prevent UnicodeDecodeError parsing iptables rule with comments If one or more iptables rule contains a comment with a non-unicode character, an UnicodeDecodeError would be raised.
sshuttle: where transparent proxy meets VPN meets ssh
=====================================================
As far as I know, sshuttle is the only program that solves the following
common case:
- Your client machine (or router) is Linux, FreeBSD, MacOS or Windows.
- You have access to a remote network via ssh.
- You don't necessarily have admin access on the remote network.
- The remote network has no VPN, or only stupid/complex VPN
protocols (IPsec, PPTP, etc). Or maybe you *are* the
admin and you just got frustrated with the awful state of
VPN tools.
- You don't want to create an ssh port forward for every
single host/port on the remote network.
- You hate openssh's port forwarding because it's randomly
slow and/or stupid.
- You can't use openssh's PermitTunnel feature because
it's disabled by default on openssh servers; plus it does
TCP-over-TCP, which has `terrible performance`_.
