Ubuntu 18.04 Firewall update program. We have a mail server that is constantly being probed by people trying to login. I intend to setup a counter on the auth server. When the ip has failed x times i will enter the ip address in a table. You will write a script that takes the entry from the table and adds it to the block list on the firewall. You will poll the table every few minutes (config option) You will either block all access to the ip or a specific post if it is defined in the table.

Hello, Actually there are already developed and widely used open-source software to perform your requests -- basically to block brute-force probing IPs either for permanently or temporary based on a time setting. Since these software work automatically based on your configuration you dont have to manually work on any IP and/or deal with false/positive alerts. Whats more that these security tools are not suitable for SMTP only but we can configure it for SSH, FTP etc. services too. Fail2ban and CSF firewall are the 2 good examples of these security tools. I can implement both of them on your server and based on your feedbacks we can proceed with one of them. If you dont like any of them and would like to develop/own a custom solution we can discuss the details of the requirement and i can do my best to implement that solution too. I am simply a professional Linux admin with more than 14 years of experiences and i am a reliable/hardworking guy with perfect communication skills. Kindly review my previously completed projects and ratings to review my experiences. Thank you for your interests and time in advance and hope to hear from you too, Regards, Pardus.
