Sorry to reply to my own mail.

Just browsing through the logs you sent, and I see that 'hostname' should be
working fine. However, you are using v1.1.5 which is very old. I would
strongly suggest upgrading to v1.2.4. It is a huge improvement over the old
v1.1 series (which is not being maintained anymore).
