Seems like the my only security hole left to plug is ftp. How do I set Vmin to only allow SFTP connections?
close port 21
inform users through the sent email to use port 22 when you create a domain
ya, I guess that would do it.
thanks for all of your help today ronald.
Ok so how does one close port 21? I’m a bit familiar with the Linux Firewall under Webmin. But am no expert
is it as simple as adding a rule to the IP tables
DROP
Destination TCP or UDP port -> equals -> 21
?
i see a lot of other settings there I do not understand, so I don’t want to shoot my server in the foot. 
I can also as our
I use this:
-A INPUT -p tcp -m tcp --dport ftp -j DROP
not sure if udp needs to be blocked too.
You can set that in the webmin/Linux Firewall module.
Create a new rule.
Action to Take - drop
Network Protocall = TCP
Destination TCP or UDP port enter ftp where you would normally enter a single port number
click save.
click apply configuration
I do not use ftp.
I only use sftp on port 22 and this works for me…
