Log in or register, to view the original The module is designed to monitor the open ports on the list of assigned IP notifications of the responsible person in case of incorrect port state (it must be opened and at the time of verification it has been closed or vice versa it must be closed and at the time of verification it has been opened).Functional requirements for the module.The module must provide regular checking of the port status for a specific IP list and a set of ports for the assigned IP.Requirements for the implementation platform.The module must represent a micro-service implemented on Symfony (or pure php).For its correct operation, the following components must be installed:PHP 7 or higherMYSQLRedisphp-fpmnginxopensslThe module must work properly with the Unix/Linux OS.System architecture needs.The database must include the following tables with the following set of columns: List of IP addresses (IP) StolbetsType DescriptionidintAutoIncrementisActivetinyintMarker should check IP or not (1 - check, 0 - no)titlestringIP address noteipstringIP-addressportRageintid lines with a port set from the port set table List of ports (ports) StolbetsType DescriptionidintAutoIncrementopenPortsstringList of open ports that should be checked.Options indicationSimple list through the closed (1,2,3 should check the ports 1, 2 and 3) port range (1-5 should check all ports from 1 to 5) Also conditions can be combined for example 1.2,5-10 - indicates that you should check the first, second and ports from the fifth to the tenthclosedPortsstringList of closed ports that should be checked.Options indicationSimple list through the seventh (1,2,3 should check the ports 1, 2 and 3) port range (1-5 should check all ports from 1 to 5) Also conditions can be combined for example 1.2,5-10 - indicates that it should check the first, second and ports from the fifth to the ten One time every 10 minutes the system starts a crown task, which pulls out the IP address tables of the lines in which isActive = 1 and checks the port set on the list from the linked table (ports are pulled by the IP.portRange = ports.id criterion).If, as a result of the verification, any of the ports does not meet the condition of openness or closure to the e-mail in the system must be sent a letter with the indication of the domain and the deadline of expiry (this sending is not required).Check the port for opening can be trying to open the socket (fsockopen($ip, $port, $errNum, $errStr, 1);) if the port is closed, then when the socket is tortured the socket will jump out Exception, which can be considered as the closure of the port.In case of successful opening, you should not forget to close it.
