My shopping list includes: - remove ftp(1) - remove ftpd(8) - remove telnet(1) - remove telnetd(8) - remove ftp:// and http:// from libfetch. This is 2021 and we should all use https://. - replace DNS lookups with DoH and/or DoT. Why let your ISP see your DNS traffic? > > I'm happy to make a port for it if anyone needs it. Comments? I've started working on splitting ftp and ftpd into an external git repo. The problem I've encountered is that though only ftp and ftpd are left the resultant repo is still 1.2 GB. If my last attempt fails, there is a choice between a 1.2 GB repo and burning ftp forever then the choice is clear: burn it forever. Adding the following as an option: Also note that the tnftp ports are the NetBSD ftp and ftpd. The FreeBSD ftp and ftpd are simply copies of tnftp and tnfpd. Would it make more sense to share our customizations with NetBSD and we simply reply on NetBSD for the client and server in our ports? This last option might be simpler than creating a port. Personally, I'd suggest we remove the ftpd server *AND* ftp client and rely on ports. Having worked on UNIX, Internet security, and firewalls over the last 3/5 of my almost 50 year career, I have lamented the existence of the FTP protocol back in 1995 and I hate the FTP protocol with greater a passion today. Let's simply remove all vestiges of FTP from the base system, including libfetch, sooner than later. We don't need it now that we have HTTPS and POST; and sftp. I think we should make it our goal to remove any and all unencrypted protocols from FreeBSD by 2025. -- Cheers, Cy Schubert <Cy.Schubert@cschubert.com> FreeBSD UNIX: <cy@FreeBSD.org> Web: https://FreeBSD.org NTP: <cy@nwtime.org> Web: https://nwtime.org The need of the many outweighs the greed of the few.
