Description of problem: The ss command's -K | --kill option can be used to forcibly close sockets. This is very useful for scripting failover in a high-availability setting. In particular, it can be used to reset the server end of TCP connections so failback will work if a client reconnects using the same source socket. Other Linux distributions such as Debian and Ubuntu enable this kernel option. Version-Release number of selected component (if applicable): all How reproducible: This is wishlist, so always. Steps to Reproduce: 1. ssh 127.0.0.1 2. Try "ss -tanH --kill state established src 127.0.0.1:22" If this worked then it would print the connection(s) that were closed. Can see connection(s) still exist with above command but without --kill option. Actual results: Does not close connection(s) and print details Expected results: Closes connection(s) and prints details Additional info: Kernel config says # CONFIG_INET_DIAG_DESTROY is not set This is the case on RHEL 8 and 9.
