When I opened ftp command prompt and typed
open mydomain.com, it gave me the following and I think that this is a security vulnerable.
connected to mydomain.com. 220----- Welcome to Pure-FTPd [privsep] [TLS] ----- 220- you are user number 1 of 50 allowed. 220- local time is now 13:18. Server port: 21 220- IPv6 connections are also welcome on this server. 220 you will be disconnected after 15 minutes of inactivity. user <mydomain.com:<none>>:
However, when I tried another websites like
open stackexchange.com, it returned nothing.
Can anyone tell me how to apply more security on ftp connections on my server?
