scp is sort of a secure form of ftp. All the transactions are done via strong encryption, so passwords and such can't be picked up by packet sniffers. Telnet is replaced by ssh in the same way. > By the way, is there anyone out there who actually has OS X's built-in > FTP sharing working on a computer that's behind a cable/DSL router, > regardless of brand? I connect to my G4 machine at home all the time by ftp. It sits behind a Netgear router and port 21 is forwarded to the G4. Here's an example session done from my office via the command line so you can see what's going on. > math> ftp lml.homedns.org > Connected to lml.homedns.org (12.220.171.30). > 220 192.168.0.2 FTP server (lukemftpd 1.1) ready. > Name (lml.homedns.org:lee): lee > 331 Password required for lee. > Password: > 230- > Welcome to Darwin! > 230 User lee logged in. > Remote system type is UNIX. > Using binary mode to transfer files. > ftp> quit > 221- > Data traffic for this session was 0 bytes in 0 files. > Total traffic for this session was 283 bytes in 0 transfers. > 221 Thank you for using the FTP service on 192.168.0.2. You can use telnet to debug many of the standard services. If you telnet into the right port, you can see the negotiation.
