UFW UncomplicatedFirewall

sudo ufw allow ssh

sudo ufw enable

sudo ufw allow 8000/tcp

Allow specific ip address for client of the web server:

sudo ufw allow from 188.12.139.142 to any port 8000

Allow a range of ip addresses for all the ports:

sudo ufw allow from 192.168.0.0/24

Then disallow all the others:

sudo ufw default deny incoming

Verifica porte

Il comando ss può mostrare le porte che stanno ascoltando le connessioni e le reti da cui accetta tali connessioni. È un’alternativa moderna al vecchio comando netstat. Esegui il seguente comando per visualizzare le porte aperte:

sudo ss -ltn

View UFW logs and status

tac /var/log/ufw.log | head -n 20

To see the status:

sudo ufw status verbose

With priority:

sudo ufw status numbered

You should see something like:

sudo ufw status verbose
Status: active
Logging: on (low)
Default: deny (incoming), allow (outgoing), deny (routed)
New profiles: skip

Log Rotation

To use logrotate for managing your logs, you need to create a configuration file for logrotate. Here's a step-by-step plan:

1. Create a new logrotate configuration file, e.g., /etc/logrotate.d/uvicorn. In this file, specify the path to your log files, the rotation interval, the number of backups to keep, and any other options you want to use.

/home/user/projects/wl-semsearch-poc/*.log {
    daily
    rotate 7
    compress
    missingok
    notifempty
    create 0644 user group
}

This configuration will rotate the log files daily, keep 7 days of backups, compress rotated files, and create new log files with the specified permissions and ownership if they don't exist.

Finally, ensure that logrotate is run daily by the cron daemon, you can add a cron job manually with crontab -e and adding the following line:

crontab -e

@daily /usr/sbin/logrotate /etc/logrotate.conf

This will run logrotate daily using the main configuration file /etc/logrotate.conf, which includes all files in the /etc/logrotate.d directory.
