Re: Finding TNS listener ports

Bala, the solution is a tool called "nmap", very popular among the network administrators:

root_at_umajor:/home/mgogala# nmap ora19c Starting Nmap 7.80 ( https://nmap.org ) at 2020-07-29 14:58 EDT Nmap scan report for ora19c (192.168.2.53) Host is up (0.00034s latency).
rDNS record for 192.168.2.53: ora19c.home.com Not shown: 997 closed ports
PORT     STATE SERVICE
22/tcp   open  ssh
111/tcp  open  rpcbind
_*1521/tcp open  oracle*_
MAC Address: 08:00:27:6B:DB:70 (Oracle VirtualBox virtual NIC)

Nmap done: 1 IP address (1 host up) scanned in 0.36 seconds

I am sure that your network administrator will gladly allow you to install nmap.
