Alas, the only official documentation and tutorials are those included 
with the source, and the dtn-interest archives.

There is a slightly out-of-date installation guide on my website here:
http://www.melissaho.com/research/dtn/demo

The caveats/tricks you should know are:
1. Download the BerkeleyDB source and compile it with --enable-cxx:
cd build_unix
../dist/configure --enable-cxx
make
make install (as root)
2. Download tclreadline source and install it. This will give you access 
to the dtnd command line help, and in general make it easier to use/test 
dtn. One of the hooks for processing bundles is to specify a tcl command 
to run on bundles that are received. http://tclreadline.sourceforge.net
3. By default, dtnd is initialized with the conf file ./daemon/dtn.conf. 
This is a tcl file - where you can load the appropriate test functions, 
and do any node/route initializations necessary.
4. You may need to specify your LD_LIBRARY _PATH in order to run dtnd 
successfully:
export LD_LIBRARY_PATH=/usr/local/BerkeleyDB4.2/lib

For the dtnd options run it with the --help option:
./daemon/dtnd --help

After you first compile DTN2, you will need to initialize the database:
./daemon/dtnd --init-db

Then to clear the database and run dtn you can use the tidy option:
./daemon/dtnd -t

Read the error messages if it doesn't run successfully - in general, 
Mike has done a pretty good job of putting in informative enough error 
messages for you to be able to fix whatever configuration issues come up.

As another side note, I just did a fresh checkout and build on a fedora 
core 3 machine - and realized that I was missing tcl.h since I didn't 
have tcl-devel installed.

Also - we haven't tested DTN2 on solaris - your best bet (while we're 
still in the early stages) is to do development on Fedora.
