Proxy for Niche Scraper

Fail2Ban is a security tool that analyzes log files for malicious patterns and bans IP addresses that show suspicious activity. Although Fail2Ban is primarily designed to work with TCP-based protocols like SSH, HTTP, and MySQL, it can be configured to work with UDP-based protocols, including UDP flood attacks.

To use Fail2Ban to protect your server from UDP flood attacks, follow these steps:

1. Install Fail2Ban:

sudo apt-get update
sudo apt-get install fail2ban

2. Create a custom UDP log file:

Create a log file to store the UDP flood attack data. This log file should be located in the /var/log/ directory, and it should have the appropriate permissions. For example, you can create a log file named udp-flood.log:

sudo touch /var/log/udp-flood.log
sudo chown syslog:adm /var/log/udp-flood.log
sudo chmod 640 /var/log/udp-flood.log

3. Configure Fail2Ban to monitor the UDP log file:

Create a new filter file for UDP flood attacks, for example, /etc/fail2ban/filter.d/udp-flood.conf:

[Definition]
failregex = ^.*UDP.*Flood.*
ignoreregex =

Replace HOST with the actual hostname or IP address of your server, and with the IP address of the attacking host.

Next, create a new action file for UDP flood attacks, for example, /etc/fail2ban/action.d/udp-flood.conf:

[Definition]
actionstart =
actionstop =
actioncheck =
actionban = iptables -I INPUT -s  -j DROP; iptables-save
actionunban = iptables -D INPUT -s  -j DROP; iptables-save

Replace IP with the IP address of the banned host.

Finally, create a new jail configuration file for UDP flood attacks, for example, /etc/fail2ban/jail.d/udp-flood.local.conf:

[udp-flood]
enabled = true
port = 
logpath = /var/log/udp-flood.log
maxretry = 3
findtime = 300
bantime = 1800
action = udp-flood

Replace UDP_PORT with the UDP port you want to monitor.

Reload Fail2Ban configuration:

sudo systemctl reload fail2ban

Enter the settings using the gear icon (home screen) and click on it. Under "Wireless Networks", click on "Wi-Fi" and then click on "WiredSSID" and select "Change Network". Check the "Advanced" checkbox, and then select "Manual" for the proxy server. Click "Save" and close the settings.

Incoming and outgoing Internet speeds are important indicators of proxy performance because they directly influence the speed of downloading the required information. The value of the ping is important for estimating the speed - the lower the value, the better. You can find out the real speed of your proxy server with the help of proxy checker.

The term "public" should be understood to mean open proxy servers. That is, they can be used by all users without exception. They can be insecure and are often quite overloaded, so the connection speed or response time when using public proxies can be very slow.

In Windows 10 you need to go to "Settings", go to "Network and Internet", open the tab "Proxy" and make the necessary settings for the connection (under "Manual", the item should also be made active).
