I realize this is probably only relevant to about 3 of the readers, but I’m posting this so I don’t forget how to do it myself! In my efforts to ban the completely insecure FTP protocol from my life entirely, I’ve decided to disable the FTP service running on the How-To Geek server, which is running the CentOS operating system.
For whatever reason, I couldn’t find a place in plesk to do this, and I just despise everything about plesk anyway… so I took the manual approach.
First, look in your /etc/xinetd.d/ directory and see if there’s a file named psa_ftp in there. If not, you might have to make this change in your /etc/xinetd.conf file.
Open up the file as root, and look for the following section:
disable = yes
socket_type = stream
protocol = tcp
wait = no
user = root
instances = UNLIMITED
server = /usr/sbin/in.proftpd
server_args = -c /etc/proftpd.conf
Change the disable = no line to disable = yes as shown above.
Run the following command to restart xinetd
Good to go!
