Information of Latest updates

This file has the objective of describing the major changes for each merge from test to master in a similar way as a patch release notes.

Everytime Test branch is merged into master, a new entry should be created with the date and changes being merged.

Nov 4th 2020

• Official support for Ubuntu Server 20.04 on Raspberry Pi (32-bit and 64-bit).
• Handle special characters better when managing OpenVPN clients.
• Show expired OpenVPN certificates as such when using 'pivpn -l'.
• Improved OpenVPN and WireGuard availability detection.
• Reload WireGuard instead of restarting so it doesn't kick existing clients.

Jul 24th 2020

• Added ability to remove client by index. For example, when the user is presented with '2) phone' he can remove the client by typing either '2' or 'phone'.
• Added ability to remove a client non-interactively with 'pivpn -r phone -y'.
• When choosing to use Pi-hole, do not whitelist the specific VPN interface. Instead, use Pi-hole's built-in command 'pihole -a -i local' to allow listening from on the VPN interface. DNS resolution on the LAN shouldn't break anymore in some circumstances if the user changes Pi-hole's listening behavior after installing PiVPN.

Jun 9th 2020

• Dual VPN mode, use both WireGuard and OpenVPN by running the installer script over an existing installation.
• Generate a unique pre-shared key for each client as per the WireGuard protocol to improve post-quantum resistance.
• Added the ability to regenerate the .ovpn config when the client template changes (issue #281). Use 'pivpn -a -o'.
• Added the '--show-unsupported-nics' argument to the install script for those who need PiVPN on virtual servers where the available network interfaces may not be detected reliably (issue #994).
• Clone the git repo to '/usr/local/src/pivpn' and replace all other locations with symlinks (issue #695).
• Simplified the OpenVPN installation flow by moving some settings behind a "customize" dialog.
• Temporarily disable 'pivpn -up' until a proper update strategy is defined. See this commit for more information.

Mar 17th 2020

• Switch to Bullseye repository on Debian/Raspbian. The bullseye repository is less likely to offer broken packages and it's also supported by Raspbian, meaning there is no need to manually compile WireGuard on older Raspberry Pis.
• Adding a PPA on Ubuntu requires 'software-properties-common' with may not be installed on servers.
• Avoid IPv6 leak by routing IPv6 through WireGuard.
• Download OpenVPN key via HTTPS if retrieving via keyserver fails.
• Show connected clients data rates with dotted decimal notation using 'pivpn -c -b'. It's useful because the human readable format does not offer enough precision to tell if a client is sending very little data.
• Use 'apt-cache policy' to decide whether we need a repository or not.
• Use lowest APT pin priority that allows package upgrades (more information on pull request #963 and #983).

Feb 17th 2020

• When offering to use Pi-hole, identify VPN clients via clientname.pivpn using a dedicated hosts file. Clients can now be resolved by their names and also show up in the Pi-hole dashboard.
• Decide whether to tell dnsmasq to listen on the VPN interface depending on the user settings. The default Pi-hole listening behavior is Listen only on interface whatever, which means dnsmasq needs to know the additional VPN interface. However, if the user has Listen on all interfaces or Listen on all interfaces, permit all origins, then, there is no need to add the interface (self-explanatory).
• Set static IPs by default when using OpenVPN.
• Restrict access to automatic backups (.tar.gz) of /etc/wireguard and /etc/openvpn to root.
• Drop libmnl-dev requirement on armv6l as it's not required anymore to build wireguard-tools.
• Require apt-transport-https on Ubuntu < Bionic and Debian < Buster as those older version have APT without HTTPS repositories support and the script uses them.
• Import OpenVPN PGP key from keyserver as it should be more secure than downloading from the website since we specifically tell the keyserver which key we want, referring to its fingerprint.

Jan 31th 2020

• More validation of user input
• Check if package installation is successful
• Detect netmask when setting a static IP
• Avoid adding repositories if they already exist
• Switch DH params from 2ton.com.au to RFC 7919
• Using 'install' to copy files into place
• Move the self check to a different script and use it for both OpenVPN and WireGuard
• Add 'pivpn -wg' to update WireGuard on older Raspberry Pis

Jan 20th 2020

• Allow setting DHCP reservation preference with --unattended
• Flip condition check on $dhcpReserv: first check if empty, and if not, check if it's not 1. Doing it the other way (first check if not 1) would give a shell error if $dhcpReserv was empty.
• Prepend 'pivpn-' to unstable repo files to limit naming conflicts
• Update variables inside unattended examples
• Remove openvpn logging setting when uninstalling the package
• Run 'apt-get update' after removing the WireGuard PPA

Jan 18th 2020

Distro Support, Bug Fixes, Unattended install

Tested and added Support on Debian 9 tested and added support on Ubuntu 16.04 & 18.08

• Fixed wireguard not installing, added pkg cache update after adding ppa
• added kernel headers to dependencies as its requred for wireguard-dkms unattended install
• When user is provided and doest exist, it will create one without password set
• Use metapackage to install kernel headers on Ubuntu

Jan 8th 2020

Updates and improvements Issue #871: fix backup script

install.sh installScripts function: update script not being copied over to /opt therefore update funcion was probably broken. changed script to copy all .sh scripts from .pivpn/scripts directory.

Issue #871: fix backup script I was probably very drunk when i first wrote this backup script. fixed it, now works with new code refactoring, loads vars from setupVars Added backup for wireguard Moved script to global pivpnscripts. Added backup script to bash-completion Added backup script to pivpn script

update.sh Commented the update from master branch to avoid users trying to update test from master.

Updated LatestChages.md

Jan 7th 2020

Changes for FR #897 Support For DHCP IP Reservation

Main:

• added If statement to skipp SetStaticIPv4 if dhcpRserv=1

getStaticIPv4Settings:

• Added Whiptail asking if user wants to use DHCP reservation Settings, this will add dhcpReserv and skip setStaticIPv4 while still logging everything. ConfigExample files:
• Added staticReserv=0 to config examples. so it can be used with Unattended install
  • 0 means static ip will be setup.
  • 1 means DHCP Reservation will be used and no chage will be made to the interfaces

Updated LatestChanges

Jan 6th 2020

  • Messages and titles could cause confusion to users and specially developers
• Moved Funcions Comment to correct place.
• DistroCheck Function:
  • Moved up before other functions so it better refflects the order they are called.
  • changed Case identation to make it easier to read.
  • Added info to # compatibility Comment, Removed unecessary comments
  • added break to exit out of case, easier to understand that the script should move on.
• Added Shellcheck ignores,
• chooseinterface Function:
  • Changed function Logic and cleaned it up
  • Fixed Issue #906
  • Added exit code if no interfaces are found

Jan 2nd 2020

• Fix mv command when copying the DH parameters to final destination

Dec 30th 2019

• Fix paths inside the update script
• Use the wireguard script for WireGuard as well
• Updated the README in accordance to changes in the test branch

Dec 29th 2019

• Handle running the install script over an existing installation (as the script already did before branching to test-wireguard), providing:
  • Update, downloads latest scripts from git repo
  • Repair, reinstall PiVPN while keeping existing settings
  • Reconfigure, start over overwriting the existing settings
• Tag iptables rules as an attempt to make sure that the uninstall script only removes PiVPN rules
• Change the armv6l installation to reflect the split of WireGuard snapshots into wireguard-linux-compat and wireguard-tools

Dec 27th 2019

• When suggesting to use Pi-hole, use the VPN server IP instead of the LAN IP to allow DNS resolution even if the user does not route the local network through the tunnel.
• Format listCONF in a similar way as listOVPN
• Specifically look for a free octet in the last word of clients.txt and not just any word. Necessary otherwhise public keys starting with a number will match against an octet. Example: if line is 'name 5abcdefgh 4', then looking for ' 5' will match but '5$' will not (correctly).
• 'pivpn -c' will show the Connected Clients List for WireGuard too

Dec 10th 2019

• Use dedicated openvpn user and group for increased security
• Added basic safeguards to avoid wrecking /etc/ufw/before.rules
• Applied some Shellcheck suggested changes.
• Added safeguards to rm -rf when downloading the git repo.
• Use more variables instead of hardcoding data
• Add local resolver as DNS option

Dec 3rd 2019

• Better client stats formatting

Dec 2nd 2019

• Properly avoid pulling unwanted packages from unstable repo:
  • Currently apt pulls all packages from the unstable repo because the script intendation created the file 'limit-unstable' with tabs in it. Fixed using printf to create a multiline file.

• Accept debug fixes using just the enter key

Nov 25th 2019 - On Master

• Changed pivpn command exit codes from 1 to 0
  • exit code 1 means general error hence should not be used for exiting successfully
• added backup script to backup openvpn and pivpn generated certificates
• added update script to update /opt/pivpn scripts, -t | --test | test update from test branch
• Fixed hostname length issue #831
  • the script now checks for hostname length right at the beginning and prompts for a new one.
  • HOST_NAME to host_name, as best practice variables with capitals, should be used by system variables only.
• fixed ubuntu 18.04 being detected as not supported OS, now fully supported and tested.
• changed how scripts are copied to /opt/pivpn, it hat a lot of long repetitive lines, now it copies all *.sh files making it easier to manage when adding new scripts/features
• Changed how supported OS are presented when maybeOS_Support() is called.

Nov 19th 2019

• Added Ubuntu Bionic support

Nov 16th 2019

• Removed persist-key and persist-tun from the client config.
• Reverted keepalive setting on the server to smaller values.
• See @TinCanTech's posts for the reasons of the above two: #864 (comment)
• Copied validDomain() function from the test branch.
• Removed 1024 bit certificate options, since on Buster OpenVPN does not start with such small certificates (It's related to OpenSSL 1.1.1).

• Fixed the issues with special characters in OVPN12 files.

Oct 17th 2019

• Allow subdomain in custom DNS search list.
• Unified PiVPN configuration into the single /etc/pivpn/setupVars.conf file.
• Functions that ask the user for the port, protocol, dns, domain don't apply the setting anymore, they only save the variable on disk. Settings are applied in confOpenVPN, confOVPN, confWireGuard.
