Build instructions

Install dependencies

Install golang and configure go. Git clone this repo in ~/gocode/src/github.com/kushaldas/unoon.

Install go dependences:

In fedora: sudo dnf install libpcap-devel redis

Start redis service:

sudo systemctl start redis

Install python dependencies:

In Fedora: sudo dnf install python3-qt5 python3-redis python3-yaml python3-psutil audit

Build

Build the go portion with:

go build github.com/kushaldas/unoon/cmd/unoon

Setting up audit rules

Put the following in the /etc/audit/rules.d/audit.rules file.

## First rule - delete all
-D

## Increase the buffers to survive stress events.
## Make this bigger for busy systems
-b 8192

## This determine how long to wait in burst of events
--backlog_wait_time 0

## Set failure mode to syslog
-f 1

-a exit,always -F arch=b64 -S connect,listen,bind -k unoon_network
-a always,exit -F arch=b64 -S exit,exit_group -k unoon_exit

Remember as this tool is in the development stage, we will keep changing and adding a lot more rules in the coming days.

In future we may add rules in a different way, but for now, we will use auditd itself.

$ sudo systemctl start auditd
$ sudo systemctl status auditd
$ sudo systemctl stop auditd
$ sudo auditctl -l
-a always,exit -F arch=b64 -S connect,bind,listen -F key=unoon_network
-a always,exit -F arch=b64 -S exit,exit_group -F key=unoon_exit

On Fedora you may have to use the service command.

$ sudo service auditd restart
$ sudo service auditd stop

The last command should show you output as shown above.

configuration

You should run the redis server along with a password for production, and you can provide the same using the following format in /etc/unoon/unoon.yml file. You should atleast write the standard username who will receive the desktop notifications.

If the file does not exist, it will assume no password is required, and it will also try to find the user with uid 1000.

---
user: "kdas"
server: "localhost:6379"
password: "yourpassword"
db:     0

Start

Start the backend:

sudo ./unoon

You can pass a different interface name with -device flag to the unoon executable.

Next, create the database directory and also the sqlite database.

sudo mkdir /var/lib/unoon
sudo python3 ./desktop/udesktop/db.py

Start the frontend:

sudo python3 ./desktop/udesktop/second.py
