Hi there, I can help you with security audit and automation of the firewall setup to block fraudulent / DDoS type of behavior. I'll need to have ssh access to your Ubuntu box and will use iptables to set it up.

Hello, Nice meet you! I have read your project requirements and then I am sure I can complete that project. I can help you. Thank you.

ok i understood your requirement but I have few doubts, text me so I can clear all my doubts right away, I can help you and i am ready for work. Thank you.

I am a freelancer and my working ground is based on system operation. Like, it could be Linux,AWS and other technical support. I can do anything that is related to my job. Also I have a handful experiences on this ground as I have been roaming here for around 3 long years.

This can be done with an api, I have 8+ year experience in Linux and troubleshooting. Worked in 3+ years in data centre.

I have experience in making automation scripts which manipulate IP tables. I am bidding 30 USD. Great offer for the following : I have a dedicated server (OVH) with Ubuntu 20.04 running a website via NGINX and a service using TCP/IP protocol on a specific port. One script or program to monitor the amount of traffic to the port your service is on. This program shall record and track the amount of traffic from each IP. There have been situations in the past where I have identified high bandwidth consumption coming from certain IPs/hosts, basically an attempted DDOS attack, which was interrupted by blocking the addresses/ASN. I have a formula for deciding what a DOS or DDOS attack looks like and this program shall block the IP for a while. Only some IPs which are abusive shall be blocked. For some time and then longer until they stop bugging the site. Also they shall not be blcoked permanently. Only dynamically as needed. I would like to automate, if possible, this checking of IPs with high bandwidth consumption and block them automatically. I shall be automating the blocking and unblocking. I can do more, but that is not really required for your case and it shall increase the complexity. Maybe implement some system to avoid other possible network problems as well. You can inform me what you think those are or I can find and suggest after seeing the traffic. If you want to pay more than the bid after the work is done, you are welcome. Regards, Khawar Nehal

I have 20+ years of experience working with Linux and opensource software. I have been deploying and managing servers and infrastructure for large scale telecom operators. I have extensive experience with high availability web-applications with multi-tier deployments. I can configure different rate limits for your application in NGINX. This will automatically throttle or drop requests from clients making connections over defined limits. NGINX also support putting restrictions using GEO IP locations if you want to block traffic from certain countries. I can also do it using IPTABLES which will put hard limit on connections per second per client.

Hi sir You can use limit to blocking an IP by number of request per second. Please contact to me if you want do it. Thank you
