  • We have below questions on this :
    1) How many maximum sockets Connections are possible for a particular port onthe Redhat Server?
    2) Is there a kernel parameter which can be modified socket connections for a particular port to extend the number of socket connections for a particular User or a program?
    3) what is the command to monitor the activity carried out on a particular network Port and network sockets related to a process port?
    4) If Process XYZ is using a particular port 12344 , is there a forceful way by which another program ABC can interfere with Process XYZ and start using the port 12345 forcefully?
