Actually, discussions of John the Ripper are only appropriate here if
they pertain to usage of John on Owl.  But since you've already posted
the question...

You're barking up the wrong tree.  The hash you have looks like it
might be a raw MD5 hash represented in hex.  John does not support raw
MD5 hashes, it only supports a higher-level algorithm (originally
developed for FreeBSD, but now also used by other Unix-like systems
and Cisco IOS) that uses MD5 as an underlying cryptographic primitive.

You may want to try out MDcrack instead, see
