FTP Must Die
FTP is definitely outdated, and there are better uses in many circumstances. But I find some of these criticisms a bit odd.The client listening was largely solved by 'passive' mode, and just about every server and client supports this now.The firewall and NAT interaction is awkward, but most modern firewalls can deal with this automatically (as long as there's no SSL involved)And yes, the RFC is 20 years old. But so are many RFCs for long-established veteran protocols that we use all over the net.In many cases I'd be happy to see FTP replaced (all those anonymous FTP servers may as well be HTTP now), but it's really not that bad.
