21 port is enabled in CSF but showing closed

Post by Khalequzzaman »

Hello,

21 port is enabled on my server but when I run the command:

Code: Select all

[root@server1 ~]# nmap -p 21,22,80,443 x.x.x.x

Starting Nmap 6.40 ( http://nmap.org ) at 2020-03-22 12:22 +0530
Nmap scan report for server1.xxxxxxxxxx.com (x.x.x.x)
Host is up (0.000079s latency).
PORT    STATE  SERVICE
21/tcp  closed ftp
22/tcp  open   ssh
80/tcp  open   http
443/tcp open   https

Nmap done: 1 IP address (1 host up) scanned in 0.07 seconds
[root@server1 ~]#
Anyone know how can I fix the issue?

Regards,
Khalequzzaman
