[Proftpd-user] Removing Port Scan Info

Hello everyone,

I just did a port scan of my proftpd server and here is what it came back
with.

PORT     STATE    SERVICE       VERSION
2222/tcp open     ssh           ProFTPD mod_sftp (protocol 2.0)
2223/tcp filtered rockwell-csp2
Warning: OSScan results may be unreliable because we could not find at least
1 open and 1 closed port
Device type: general purpose
Running: Linux 4.X|5.X
OS CPE: cpe:/o:linux:linux_kernel:4 cpe:/o:linux:linux_kernel:5
OS details: Linux 4.15 - 5.6, Linux 5.0 - 5.4
Uptime guess: 17.077 days (since Mon Jul 12 18:25:28 2021)

Is there any way to change or remove the version Information (ProFTPD
mod_sftp (protocol 2.0)) ?

Kinda helps a wanabe hacker.

Thanks for your thoughts.
Brad
