Installation

This guide is written for Ubuntu. For other Linux flavors, adapt commands where needed.

(1) Allow Root Login

We'll ensure that the root user can login.

1. Configure your root user password:

sudo passwd

See this page for more information on the root user.

(2) Enable Process Isolation

We'll ensure that non-root users are unable to see the project-tanya service.

1. Switch to the root user:

su

2. Install dependencies:

apt install -y vim

3. Open /etc/fstab with vim:

vim /etc/fstab

4. Add the following line:

proc /proc proc defaults,nosuid,nodev,noexec,relatime,hidepid=1 0 0

5. Reboot your system:

reboot

6. Check that your non-root user cannot see root processes:

ps aux

See this page for more information on process isolation.

(3) Disable Process Tracing

We'll ensure that non-root users cannot use ptrace capabilities.

1. Switch to the root user:

su

2. Open /etc/sysctl.d/10-ptrace.conf with vim:

vim /etc/sysctl.d/10-ptrace.conf

3. Change the kernel.yama.ptrace_scope value to 2:

kernel.yama.ptrace_scope = 2

4. Reboot your system:

reboot

5. Check that the ptrace_scope is set to 2:

sysctl kernel.yama.ptrace_scope

See this page for more information on process tracing.

(4) Install .NET

We'll ensure that project-tanya can be compiled with .NET.

1. Switch to the root user:

su

2. Add the Microsoft package repositories:

• See https://docs.microsoft.com/en-us/dotnet/core/install/linux.
• Be sure to carefully follow instructions for your Linux flavor.

3. Install .NET 6.0:

apt update && apt install -y dotnet-sdk-6.0

(5) Build Service

We'll build project-tanya, so we can register it as a service:

1. Switch to root user:

su

2. Open the /root directory:

cd ~

3. Install dependencies:

apt install -y git

4. Clone this repository:

git clone https://github.com/XRadius/project-tanya

5. Open the project-tanya directory:

cd ~/project-tanya

6. Enable execution of the build script:

chmod +x service-build.sh

8. Run the build script:

./service-build.sh

(6) Install Service

We'll install project-tanya as a service:

1. Open the bin directory:

cd ~/project-tanya/bin

2. Run the installation script and follow the instructions:

./service-install.sh

Once you've followed these instructions, project-tanya is ready for use!
