If I perform port scanning against a standard CentOS-7/RHEL-7 server or desktop, where do I see the logs? I have searched the /var/log directory but did not see any port scan related logs.
NB: I used
# nmap -p 1-65000 target-ip-address
There is no firewall between Kali linux (scanner machine) and CentOS-7 server (target machine). The two are connected by a switch, and belong to the same subnet, and same vlan. I can ping target machine, and I can see open ports too. But I need the logs. I can't see them, on the CentOS server side.
