Qubes-Whonix style] }} Physical isolation requires: * {{Other_Platforms}} * Also refer to Physical Isolation [[#Security and Support Status|Security and Support Status]]. == First Time Users == {{Default_Passwords}} {{First_Time_User}} == Technical Introduction == The default {{project_name_short}} configuration consists of two virtual machines (VMs) running on the same physical host. This means any exploits targeting the VM implementation or the host can still break out of the torified client VM and expose the IP address of a user. Further, any malware running on the host has full control over all VMs. To protect against these attacks a different approach is required -- physical isolation. In this configuration the gateway system is installed on separate hardware, which drastically reduces the [https://en.wikipedia.org/wiki/Trusted_computing_base trusted computing base (TCB)] by more than half. The following instructions describe how to install and configure two computers and set up an isolated point to point network between them. Alternatively an ordinary, completely isolated, LAN behind the {{project_name_gateway_long}} can be set up. This way one computer acts as the client ({{project_name_workstation_long}}), while the other is the proxy ({{project_name_gateway_long}}) which transparently routes all the {{project_name_workstation_long}} traffic via Tor. The {{project_name_gateway_short}} on its own physical device can be run either directly on hardware or inside a VM. Both options have distinct advantages and disadvantages, but using an additional VM for the {{project_name_gateway_short}} is unrecommended. In contrast, the {{project_name_workstation_short}} should always be installed in a VM because this will hide hardware serial numbers. Also read the wiki entry recommending [[Whonix-Workstation_Security#VM_Snapshots|use of multiple VM Snapshots]] for better security. In this configuration the host operating system(s) should only be used for downloading operating system updates, hosting {{project_name_gateway_short}} or {{project_name_workstation_short}} and nothing else. The configuration is also more secure if the physical systems are exclusively used for hosting {{project_name_short}}, or if storage devices are separated for {{project_name_short}} and non-{{project_name_short}} use cases. The reason is this avoids any potential infection of the {{project_name_short}} hard drive by another operating system. = Warnings = Please note the following warnings about physical isolation: * This configuration is less tested than VM builds. More rigorous testing by the {{project_name_short}} community is required. * These instructions are difficult to comprehend for non-technical Linux users. * [[Dev/Build Anonymity|Build Anonymity]] has not been considered for this wiki chapter. This refers to staying anonymous while building {{project_name_short}} from source code. Since building {{project_name_short}} requires a unique selection of software to be downloaded, the ISP can likely guess that a user is building {{project_name_short}}. * It is essential to read the [[Dev/Build_Documentation/VM|warnings]] in the [[Dev/Build Documentation‏‎|latest build instructions for VM images]]. Some of these apply to physical isolation such as {{Code2|Don't add private files to {{project_name_short}} source code folder!}} and {{Code2|Check if the OpenPGP public keys are still up to date}}. * This chapter currently lacks detail concerning {{project_name_gateway_short}} and {{project_name_workstation_short}} MAC addresses, see: ** [[Protocol-Leak-Protection and Fingerprinting-Protection|Protocol Leak and Fingerprinting Protection‎]] ** [[MAC_Address#Using_Personal_Computers_in_a_Public_Network|{{project_name_short}} in public networks / MAC Address]]

Alternatively, an existing computer that is already in use can be utilized for {{project_name_gateway_short}}. To offer some isolation, all internal and external drives should be disconnected, with boots occuring from an eSATA, USB or another internal drive into a clean environment. For non-anonymous use, the physical arrangement can be used as is without any modification. This includes the use of a non-anonymous home (dial-up) Internet router, without any changes. In contrast anonymous use requires: # {{project_name_gateway_short}} # an anonymous 3G/4G/5G modem or an anonymous WiFi adapter (see below) # {{project_name_workstation_short}} In terms of the specific hardware used for {{project_name_gateway_short}}, various devices are feasible and it does not have to be a big desktop computer or ordinary server. Alternatives include:
* smartphone Due to the lack of an ethernet interface this is a difficult configuration and beyond the scope of the {{project_name_short}} documentation. However, as a tip some (after market) firmwares support USB-host. This makes it possible to plug USB devices into your phone, such as an USB ethernet card. For example, some rooted Android smartphones can [https://web.archive.org/web/20210622003453/http://android.galoula.com/en/LinuxInstall/ install] Debian Linux. * [https://en.wikipedia.org/wiki/Ultra-mobile_PC ultra-mobile personal computer (UMPC)] * pad or tablet * notebook or netbook * formerly a [https://en.wikipedia.org/wiki/Raspberry_Pi Raspberry Pi] A contributor or maintainer is required, see: [https://forums.whonix.org/t/whonix-raspberry-pi/723 Whonix - Raspberry Pi] development thread. * router For example, something like [https://openwrt.org/ OpenWRT]. * [https://en.wikipedia.org/wiki/Set-top_box set-top box] * and other suitable devices
How to utilize devices like a Linux server is beyond the scope of this chapter and better resources already exist on the Internet. Similarly for {{project_name_workstation_short}}, a device that is suitable should be chosen. = Pre-installation Prerequisites = {{mbox | type = notice | image = [[File:Ambox_notice.png|40px|alt=Info]] | text = {{Pre_Install_Advice}} }} == Prerequisites == Physical isolation has several prerequisites: # System requirements: Available hardware must meet the [[System Requirements|minimum specifications]]. # {{project_name_gateway_short}}: A device with at least two network adapters -- at least one of them ethernet The other one may be either an [[Essential_Host_Security#Anonymous_Mobile_Modems|Anonymous Mobile Modem]], an [[Essential_Host_Security#Anonymous_WiFi_Adapters|Anonymous WiFi Adapter]], or another ethernet or WiFi device connected to the modem/router. -- capable of running Linux. The {{project_name_gateway_short}} will run Debian. Theoretically any operating system that supports iptables or pf (packet filter) could be used. Advanced users who do not want to utilize Debian need to edit the source code. This is easy for Debian derivatives, but much more difficult for other distributions such as *BSD. In any case, the operating system choice does not really matter because this system is only used for running Tor. A cheap plug computer like the Raspberry Pi, or the hardware used by Torouter would be sufficient. # {{project_name_workstation_short}}: A device connected via ethernet to the {{project_name_gateway_short}}. It must only have this one NIC and no other network connectivity! It must also be connected by wire. If wire connections are not configured, isolation and security is significantly weakened. If the {{project_name_workstation_short}} were infected, it could jump onto another network and start leaking information. This will be the torified client system or {{project_name_workstation_short}} and it must be capable of running Debian. Any operating system can be used, but this is not recommended! If this advice is ignored, read the following [https://gitlab.torproject.org/legacy/trac/-/wikis/doc/TransparentProxyLeaks Transparent Proxy Leaks] warning, especially for Windows. # VM client: It is recommended to use a VM as the client, namely the same {{project_name_workstation_short}} that most "normal" (non-physical isolation) {{project_name_short}} users rely upon. Either [[Download]] the image or build it from source code. A generic VM image cannot leak identifying hardware serial numbers or unique software fingerprints via software updates. This ensures the VM client has the latest security features and most secure configurations, for example stream isolation to protect against identity correlation through circuit sharing, HexChat IRC hardening, {{project_name_short}} protocol leak protection and fingerprinting protection, and so on. # Host build environment: The build environment must have a working Internet connection to Debian mirrors. # Virtual console: Although optional, it is also useful to know how to open a second [[Desktop#Virtual_Consoles|virtual console]]. == Host Preparation == {{Box|text= '''1.'''

It is simpler to change these files later on after building {{project_name_short}}. }} Most configuration files work well inside VMs and on hardware. Minor issues such as deactivating powersaving, passwordless reboot, shutdown and so on are only recommended for VMs. They can be easily commented out by putting a hash # in front of them. Since they are marked, use grep to locate them.
grep -r VMONLY* *
=== Run Build Script === It is recommended to create a log of the build process by redirecting all the output to a log file. Be aware that by doing so no build progress will appear on the screen -- instead a text log file will be created in the home folder.
./derivative-maker --flavor whonix-gateway-xfce --target root --build >> ~/log-phyiso 2>&1
To optionally watch the progress, open a second [[Desktop#Virtual_Consoles|virtual console]] and type.
tail -f ~/log-phyiso
Use the following command to avoid creating a log of the build process; the build progress will then appear on screen. Note this is unrecommended because if anything goes wrong during the build, it is harder to pinpoint the exact error without a log file.
./derivative-maker --flavor whonix-gateway --target root --build
=== Final Steps === {{mbox | type = notice | image = [[File:Ambox_notice.png|40px|alt=Info]] | text = This is untested since [https://phabricator.whonix.org/T347 use /etc/network/interfaces.d instead of /etc/network/interfaces] was implemented; see footnote.

Normally it should not conflict with /etc/network/interfaces. If it does, consider: * removing source-directory /etc/network/interfaces.d from /etc/network/interfaces (if there are no other files in the /etc/network/interfaces.d folder); or * moving /etc/network/interfaces.d/30_non-qubes-whonix out of the way.

[[#Get_the_Source_Code|Get the source code]]. '''2.''' Build {{project_name_gateway_short}}. Run this command inside the {{project_name_short}} source folder. {{CodeSelect|code= sudo ./derivative-maker --target raw --flavor whonix-gateway-rpi --build --arch arm64 --kernel linux-image-arm64 --headers linux-headers-arm64 }} '''3.''' Burn the image to a micro SD card. After a successful build, burn the whonix_gw_rpi.img image to a micro SD card using gnome-disk-utility. # Within gnome-disk-utility select the SD card. # At the top panel select "options" (next to the poweroff button). # Click "restore disk image" and choose the respective file. # Click "start restoring" and wait until it is finished. # Put the SD card into the RPI3, attach an HDMI monitor, an USB-ethernet adapter as well as a keyboard and boot it. '''4.''' Configure interfaces. After login, run. {{CodeSelect|code= sudoedit /etc/network/interfaces.d/30_non-qubes-whonix }} Change the address and the gateway of eth0 corresponding to the local network / upstream router. As an example, our ISP router uses 192.168.0.1/24 for the internal network. In this case the eth0 settings would look like the following: {{CodeSelect|code= auto eth0 iface eth0 inet static address 192.168.0.11 netmask 255.255.255.0 gateway 192.168.0.1 }} '''5.''' Set up network cables. By default eth0 is the native ethernet connection of the RPI3. Hence, connect a network cable from there to the router. eth1 is the USB-ethernet adapter which should also be connected via cable to the computer running {{project_name_workstation_short}}. '''6.''' Manually set the time. The RPI3 lacks a real time clock, so it is necessary to manually set the current UTC date and time. Example: {{CodeSelect|code= sudo date -s "10 JUL 2021 17:00:00" }} '''7.''' Connect to the Tor network. Restart the networking service. {{CodeSelect|code= sudo service networking restart }} Restart the Tor service. {{CodeSelect|code= sudo service tor restart }} Note: Depending on the hypervisor it is necessary to change network settings on {{project_name_workstation_short}} in order to connect it to {{project_name_gateway_short}} (see next section). }} == Unrecommended: In a VM == {{mbox | image = [[File:Ambox_warning_pn.svg.png|40px]] | text = This configuration is entirely untested. }} {{Box|text= '''1.'''

It can be any operating system that is capable of running VirtualBox, but be aware of [https://gitlab.torproject.org/legacy/trac/-/wikis/doc/TransparentProxyLeaks Transparent Proxy Leaks]. Windows or other commercial proprietary systems are not recommended. # [[Download]] the {{project_name_workstation_short}} image. Or [[Dev/Build Documentation|build it]] from source code. # If the physical network between {{project_name_gateway_short}} and a router uses 10.152.152.* then review and edit all shell scripts and switch the internal network to something else!

If the physical network between {{project_name_gateway_short}} and a router uses 10.152.152.*, then review and edit all /etc/network/interfaces. === NAT vs Bridging === In the default {{project_name_short}} VirtualBox image, the network adapter setting for Adapter 1 (eth0) is set to internal network and will therefore not work out of the box. There are two ways to fix this: NAT (recommended) or using a bridged network (unrecommended). ==== Recommended: NAT ==== To use NAT, edit /etc/network/interfaces in {{project_name_workstation_short}} to utilize either DHCP (easier, shown in the example below) or a static IP for VirtualBox NAT.
sudoedit /etc/network/interfaces
Replace it with.

## /etc/network/interfaces in a VM
## when using Physical Isolation.

## end of /etc/network/interfaces
==== Unrecommended: Bridged Network ==== {{mbox | image = [[File:Ambox_warning_pn.svg.png|40px]] | text = This is untested. }} If bridged networking is configured, then everything should work by default. At least it should work, although it is untested by developers. The reason is {{project_name_workstation_short}} can see the MAC address of whatever network adapter it is connected to. For this reason it is recommended to change the MAC address for both the Workstation host and the {{project_name_gateway_short}}; see [[MAC_Address#Changing_MAC_Addresses|Changing MAC Addresses]]. ==== Macvtap on KVM ==== Change the network source of the ethernet nic to "macvtap" and the source mode to "passthrough". Be aware that you cannot use networking on the host anymore. ==== Attach a USB-ethernet Adapter to the VM ==== Remove the network adapter from the VM and instead attach a USB-ethernet adapter to the host and redirect it to the VM. == Unrecommended: On Hardware == Installing {{project_name_workstation_short}} on hardware without using a VM is recommended against, because hardware serials are visible to {{project_name_workstation_short}}. The instructions are very similar, if not identical, to those in the How-to: Install {{project_name_gateway_short}} - [[#Recommended:_On_Hardware|Recommended: On Hardware]] section.
