i discovered in my redhat server a openssh port open in port 1945 or somethin like that. now i filter the port with iptables but i want to do more. how can i close the port??
It depends on what starts it. As for me, i'd suggest you to check xinetd.
how can i get info about who did this and which program or prosses is using this port? how can i get any inpho about the attacker??
Try and see log files! First of all /var/log/messages, then the logs produced by sshd, and so on. I do not know so much iptables, i prefere PF under openbsd... but i suppose that iptables supports log files! at the very least, you'd know something about the IP...
thanx
