DirectAdmin Knowledge Base and Support

DirectAdmin is a web panel for a simple administration of both virtual and dedicated servers. DirectAdmin is faster, safe and more powerful than any other CP. And we know how to customize and support it.

ProFTPD cannot support both FTPS and SFTP for the same host

| 00:02:50 12.12.2022

After an upgrade of ProFTPD to the version 1.3.8 one can see the error: 

mod_sftp/1.1.1: Server 'ProFTPd': cannot support both FTPS (TLSEngine on) and SFTP (SFTPEngine on) for the same host

Here is a guide on how to fix it on a server with DirectAdmin.

IMPORTANT: The steps below will disable FTPs on your server, forcing you to use sFTP with your FTP-credentials. Do not follow the steps, if you're not sure to understand all the consequences.

perl -pi -e 's/TLSEngine.*/TLSEngine off/' /etc/proftpd.conf

And restart proftpd:

systemctl restart proftpd

Copy the updated file to a "custombuild" folder to let the changes to survive future updates:

mkdir -p /usr/local/directadmin/custombuild/custom/proftpd/conf/
\cp -p /etc/proftpd.conf /usr/local/directadmin/custombuild/custom/proftpd/conf/

That's it.

Another solution: sFTP with FTPs

It's expected that ProFTPd on a server is already compiled with a support of sFTP and there is a file /etc/proftpd.sftp.conf existing on the server.

If you still need sFTP with FTPs on the same server, then you might install an updated config from the link: 

In order to install the updated config from Poralix's GitHub repository on a Directadmin server run the following commands as root:

mkdir -p /usr/local/directadmin/custombuild/custom/proftpd/conf/
cd /usr/local/directadmin/custombuild/custom/proftpd/conf/
wget -O proftpd.conf

and then re-install proftpd:

cd /usr/local/directadmin/custombuild/
./build proftpd

Have fun!
