I’m trying to run port knocking work on a CSF on a small VPS, i setup this:
1 - the result of csf first test ok
2 -
TCP_IN = “53,80” TCP_OUT = “53,80,113,443” UDP_IN = “53” UDP_OUT = “53,113,123” PORTKNOCKING = “3000;TCP;30;1000;1001;1002;1003” //dummy ports 3 - after csf -r
4 - after restarted the vps
5 - tryed to use knockd on pc to knock the server
knock -v 0.0.0.0 1000 1001 1002 1003 //dummy ip 6 - and less than 20 seconds use
ssh myuser@0.0.0.0 -p 3000 //dummy ip but cant connect, i never did it before, like a printf(“HelloWorld”); for me. If someone could help me i will be really glad.
