From the man page of dnsmasq:
--local-service
Accept DNS queries only from hosts whose address is on a local subnet,
ie a subnet for which an interface exists on the server. This option only
has effect if there are no --interface, --except-interface, --listen-address
or --auth-server options. It is intended to be set as a default on installation,
to allow unconfigured installations to be useful but also safe from being
used for DNS amplification attacks.
- Letting dnsmasq additionally listen on a specific VPN interface when Pi-hole is
listening on the physical interface only may be more secure than letting dnsmasq
listen on all interfaces, however, dnsmasq will stop listening on the physical
interface (breaking LAN resolution) if the user changes the listening behavior
at a later time.
For the target audience of PiVPN, it is more likely that users will set the
listening behavior to all when deciding to use Pi-hole via VPN (which is suggested
in the Pi-hole guide and most guides on the web), instead of digging into
configuration file.
This option is safe if the Raspberry Pi is inside the local network and the user
has not forwarded port 53 on their router, which is unlikely as they are installing
PiVPN precisely to avoid doing that.
- Renamed '--i_do_not_follow_recommendations' to '--skip-space-check', since
the argument actually skips the space check.
- Obtain the unattended configuration dynamically, by looking at the argument
next to '--unattended', instead of looking at the second argument, which
was a too fragile parsing.
- Because of the previous one, figuring out when no argument has been passed
to '--unattended' doesn't seem trivial, because the next argument could be
an undocumented flag as well, which would be intepreted as a filename.
- /usr/local/src, when cloning the git repository
- /opt (this one was already taken into account but I had accidentally
removed the mkdir command in the previous commit).
- Allow using 'pivpn vpn -u' to directly uninstall VPN 'vpn'
- Also allow using 'pivpn -u' with two VPNs (will present a dialog).
- During uninstall, ask which VPN to remove only if there are two VPNs
- PiVPN git repo will be downloaded to '/usr/local/src/pivpn'. All scripts
in /opt/pivpn, the main pivpn script and the bash completion file,
are now just symbolic links. Resolves issue #695.
- Remove unused call to updateWireGuard().
remove refs to /etc/pivpn/setupVars in selfcheck and debug scripts
tidy indenting
on install, check if symlink already exists before making one to avoid error
uninstall indicates which vpns are available for uninstall
selfcheck checks both protocols if both present
install - additional text in reconfigure saying 2nd protocol can be added
change to use pivpn ovpn instaed of pivpn opv when dual protocols exist
