Hi Gabriel,
just run the programm with
$ strace <your_binary>
and look at the output. (If you have no idea, mail the strace-output)
Regards
Hauke

Did you install in a non-default location, so that the libunbound shared library is not in the
dynamic loader's path?
I am running an ubuntu, fresh installed, no zone configured yet.
did you install from apt-get? Or did you compile it yourself? If from a package, then
pehraps the unbound-host does not depend on a unbound-libs package? (I am not sure how
debian/ubuntu packaged things, I just know about the fedora packaging method)
It's very likely an install problem, so you should tell us in more detail what you did.

Hi Gabriel,
Can you do ldd /usr/bin/unbound-host
Is libunbound.so.0 installed? (that would be a packager error)
perhaps ld.so has not updated its caches yet. A reboot fixes that I
think; or run ldconfig as root.
Otherwise it may have been installed in a directory which is not
searched by default by ld.so ; see man ld.so (but that would also be a
package error, I do not expect that for ubuntu).
Best regards,
Wouter

i'm guessing that you installed from source? (the unbound-host package in ubuntu
should have a dependency on the libunbound0 package)
By default, the unbound library is installed in /usr/local/lib if you do 'make
install'. However, I think that Ubuntu does not have this in its default paths
to look for libraries.
You can test this by entering
LD_LIBRARY_PATH=/usr/local/lib unbound-host
on the command line.
If so, you could either add /usr/local/lib to your standard LD_LIBRARY_PATH
configuration, or tell the build scripts to install it in /usr, by doing
./configure --prefix=/usr
make
sudo make install
In this case the library should be installed in the same location where the
libunbound0 package would put it.
Hope this helps,
Jelte

Description: reimplementation of the 'host' command
This package provides the 'unbound-host' program that is bundled with the
Unbound domain name server. This version differs from the one provided in the
package called host, which is from NIKHEF, and bind9-host, which is from ISC,
and has a similar but different set of features/options.

Yup. And if you are not using packaged unbound, what is your reason
behind your decision?

Hauke, sorry, but this doesn't make a sense at all. In case of dynamic
library missing, the program stops before doing anything at all (apart
from searching for a dynamic libraries).
And here libunbound.so.0 is missing, which you don't have to use strace at all.
Usefull tool in this case would be:
ldd <binary>
which prints dynamic libraries mappings.
But as many before said - it's likely problem of installation of
library to place where linux dynamic linker is not aware of it (ie.
/usr/local/lib).

On this note...
I'm a new unbound user and very happy with it so far. It's currently
serving recursive DNS to about 10,000 customers.
However, originally I installed the Debian Lenny .deb of unbound,
basically to try and keep maintaining unbound a lot easier.
Which was fine, everything worked very well. But the .deb was rather
old, I think it was 1.0.x from memory. This meant it lacked the
unbound-control tools as I believe they were introduced in 1.1.x . So,
due to this have since changed to running a source compiled unbound
(latest version). Everything works very well.
So, not a complaint or anything. Just a bit of feedback on why I'm
running a compiled from source unbound.
I especially liked the fine tuning unbound tutorial on the unbound
website. Was very useful.
Cheers
Dave
