Description

I would like to install FTPS/SSL on my two server instances.

• Server1 - Port 21 is setup for internal users
  
• Server2 - Port 2121 is setup for external users
  

I want to install FTPS/SSL on both servers. Does this mean I need 2 certificates 1 for each server? Is the certificate specific to each server? Can the one certificate work for both servers? If I setup the certificate for server "Server2 - Port 2121" can the same certificate be used on server "Server1- Port 21"?

Resolution

Yes, you can use the same SSL/TLS certificate for both server instances, Server1 and Server2. Titan FTP Server will store the certificate in a local certificate folder or in the DB depending on which version of Titan you are running. Simply import the certificate into each server instance using the Certificate Management utility in the administration console and the certificate will be available for use on the server.

Most importantly though is that certificates are attached to a domain name, meaning that a certificate might be valid for server1.mydomain.com or server2.mydomain.com. It's important to make sure your certificate subject name matches the domain/host name to which your client software will be connecting or they will receive a security warning. One way around this would be to purchase a wildcard certificate from your certificate vendor and have the certificate issued for *.mydomain.com, or purchase a SAN certificate valid for both server1.mydomain.com and server2.mydomain.com
