I'm looking to add SFTP support to my Objective-C / Cocoa program
using libcurl and I thought I'd get it working using the command line
first to get a feel for what the curl opts would be.

I'm on Mac OS X 10.4.8 and using the version of curl that came
bundled with the OS.

khans$ curl --version
curl 7.13.1 (powerpc-apple-darwin8.0) libcurl/7.13.1 OpenSSL/0.9.7l
zlib/1.2.3
Protocols: ftp gopher telnet dict ldap http file https ftps
Features: IPv6 Largefile NTLM SSL libz

connecting to an FTP server using curl works flawlessly

khans$ curl -u khans:<snipped> ftp://192.168.0.4

however connecting to the same host using SFTP doesn't work

khans$ curl -u khans:<snipped> sftp://192.168.0.4
curl: (1) Unsupported protocol: sftp

khans$ curl -u khans:<snipped> ftps://192.168.0.4
curl: (7) couldn't connect to host

khans$ curl -v -u khans:<snipped> ftps://192.168.0.4

What am I missing here?

thanks!
