To instruct Nmap to scan UDP ports instead of TCP ports (the –p switch specifies ports 80, 130, and 255 in this example): nmap –sU –p 80,130,255 192.168.0.1. Run a fast scan on the target system, but bypass host discovery. (Host discovery uses ping, but many server firewalls do not respond to ping requests. This option forces the test
Known SSL/TLS ports; All ports; Identify certificates expiring within x days: 60: Identifies SSL and TLS certificates that are within the specified number of days of expiring. Enumerate all SSL ciphers: True: When enabled, Nessus ignores the list of ciphers advertised by SSL/TLS services and enumerates them by attempting to establish Common Port Numbers. Description.

For example: common network ports we use in our day to day tasks include 80 for HTTP-web-based browsing in plain text, and 443 for HTTPS-web-based encrypted web pages. To summarize, a port can be defined as a logical form to identify system processes or different network services that are used to establish local or network-based communications.
The ports designated for the purpose described are 49152–65535. You can pick any ports you want in this, the ephemeral range. No one can request a port assignment from this range. For easy of use, I would start at 50,000 and increment by one as needed for each additional port. I am trying to do an audit of SSL enabled ports/services running on our Linux RHEL 5.3 servers .

TCP Outbound Checks Metrics RPC N/A: RMS only uses these ports for outbound connections. Thus, no INBOUND firewall rule changes are necessary. If the firewall is configured to block outbound ports/connections, then these ports need to be added to the allowed outbound port list. Cheat Sheet of Commonly Used Port Numbers for Linux System Administrator. Port Number is most common thing for every system admin working with the Linux operating system.
