Need help securing my FTPS server

post #1 of 11
Thread Starter 
Hi, I just managed to set up my own SFTP server. While the server worked quite well, but when I ran ShieldsUp! from GRC - I got this error:




Is there anyway to remedy this, or should I just leave it alone?

Thanks. wink.gif

This is just an assumption but I think that this security check is complaining in general about the fact that there is a FTP server running on that machine.
Maybe it didn't recognize that it is SFTP or you didn't disable the option of FTP without SHH?

edit: just to be sure: a FTP connection that is not using the SSH tunnel, other than SFTP, is considered insecure because it sends login data in plain text, iirc.

I used FTP over TLS connection - would that be enough?

I'm not sure tbh. Maybe someone with more knowledge can tell.
I just did a quick search and Wikipedia refers to FTP with SSL/TLS as FTPS, not SFTP which is used for FTP with/over SSH. Maybe that will help you while looking things up.

Looks like that site is just checking default ports, I bet if you changed it from 21 it wouldn't say that. What OS is the FTP server on? If it's Linux just use SSH, you would connect over port 22 with SSH login info.

Windows 8.1 Pro.

Also another question - it seems like my FTPS server won't work unless I use Teamviewer (a remote PC application) to connect to the machine. confused.gif

If you want to be able to access from the outside, the port has to be open.

VPN clients/services allow you to get in(on a different port, but still something) and act like you are locally on the network. This may be why you need to use team viewer first.

I am no expert in this, but in general you would have to use a non standard port if you wanted to void common attacks(I am not sure how common attacks are on FTP servers anyway).

You are connecting to your public ip right?

Something is clearly responding on 21.

If you have other computers, shut off the one with FTP and see if 21 is still open.

I have not used FTP in years, but web servers like Apache and some game servers want to know your public address(but in general virtual server or port forwarding on a router should mostly fix this issue.). I think TeamSpeak would know both(all on its own) as well, but it has been a while so I can not be 100% sure.
