Hello. I think in this case, as he is using proftpd, that what he is using is FTP over TLS, not SSH based SFTP. To answer the original question: FTP over TLS is safe as long as: - you enforce everyone using it (i.e. not allowing to fallback to non- encrypted connections), configuration for that i

Hmm … I used the word “secure” and now, “upon reflection”, I think it’s the wrong word. Instead of thinking about it as … “is it secure”? Maybe we should think about it as … “has anybody broken the encryption yet?” Then … for the choices that aren’t “broken“ yet, maybe we think about those as

You guys are confusing Ruud. Bottom line … FTP is not encrypted. Yes, you can use SFTP (aka FTP over SSH) but then pay attention to what you are doing … you’re creating access for ONE service, “SFTP”, thru your Firewall. What about all the other services (WWW? NFS? SAMBA? LDAP? And yes, Gopher?

Not exactly true - you can use an VPN tunnel based on TLS and run FTP through the tunnel. I also have no point :) On 3/16/2022 12:36 PM, Tuomo Soini wrote: There is no way to do FTP with TLS/SSL completely secure way. __
