Disable SSH version info on Telnet

Question

I need to disable SSH information while telnet to SSH port in CentOS.

telnet 192.168.10.192 22
Trying 192.168.10.192...
Connected to 192.168.10.192.
Escape character is '^]'.
SSH-2.0-OpenSSH_6.4

Please help!

Well, you can disable telnet on the server or change the port. — Orphans, Jan 31 '17 at 08:59
No he is connecting to the ssh server on port 22 not to a telnet server. — Uwe Burger, Feb 03 '17 at 09:29

Providing the protocol version is part of the SSH handshake, as can be seen here: https://www.rfc-editor.org/rfc/rfc4253#section-4.2 It cannot be disabled.

You can't. It is a part of the Protocol. SSH won't work without it. – mzhaase Feb 08 '17 at 10:20
