wfinger: WebFinger and command-line finger combined

WebFinger is a new protocol for mapping email addresses to public profile information. Despite being named after the classic finger protocol, there isn’t a version of the Unix finger command that supports the WebFinger protocol. So to fill this gap, I’ve cobbled together wfinger – the traditional finger command with WebFinger support.

  • Binary: wfinger.zip (Mac OS X 10.6 Universal Binary)
  • Demo CGI Gateway:

    Or: curl http://wfinger.habilis.net/user@example.com

Example (using web-fingerling Blaine Cook):

% ./wfinger romeda@gmail.com

[gmail.com - web finger]

The WebFinger-based output of wfinger is mainly fields extracted from the user’s profile using the hCard micro-format. To add some color, wfinger will also display the user’s latest tweet, if a Twitter account is detected. When WebFinger information can’t be found, wfinger falls back to using the traditional finger code/protocol. Thus, it still works with those who have keep the finger-protocol flame alive throughout the dark ages, like bzs and alexis at The World and Panix.

I also added code to look for a new “https://habilis.net/hfinger” relationship in account XRDs. The “hfinger” stand for HTTP Finger, and hfinger URLs should point to HTTP finger gateways that return text/plain finger output. This allows fingerd-like output to be tunneled via WebFinger resource discovery. You can see this in action by wfingering my account (chuck@habilis.net). This will be useful for people who just want traditional finger output, but are on systems that don’t allow port 79 access.

I hope wfinger will generate some interest in the WebFinger protocol amongst the command-linerati and grumpy grey-beard sysadmins, who run the internet. Share and Enjoy!
