Does the directory you specified to raidfile-config have write 
permissions for the user you're running bbstored under?

This probably means that it can't find the configuration file.

You need to look for RaidFileException.h (for RaidFile exceptions, and 
so on) which will tell you what the codes mean.

The release versions don't include the necessary symbols for gdb to 
work properly.

Did bbstored-config not work?

Shouldn't that be domain.com-cert.pem ? clientCA.pem is the certificate 
used to validate incoming client connections.

I use the unit tests in debug mode, generally. Although in this case, 
just running in debug mode would be helpful -- you can use gdb, and 
exceptions give much more information.

1/2 -- can't open file
2/8 -- raid file system encountered an os error

Firstly... let's try using the standard code but pointing it at 
different directories.

Start again from the distribution archive (without your modifications) 
and build a new version.

Use the installation scripts as described in the documentation, but 
whereever they say "/etc/box", put "/home/plalonde/etc/box"

Use the bbstored-certs script to generate a certification authority. 
Sign the CSR generated with bbstored-config. (Make sure you follow 
instructions for both of them).

Edit the bbstored.conf file to remove the "User = plalonde" line, and 
change the "PidFile = /var/run/bbstored.pid" to be a file somewhere you 
have permission to write. (I suspect this is the problem which is 
stopping this working.) "domain.com" needs to be the actual hostname of 
the machine, or "localhost" for testing locally.

Start it up with

	bbstored /home/plalonde/etc/box/bbstored.conf

When you use bbstoredaccounts, do something like

	bbstoredaccount -c /home/plalonde/etc/box/bbstored.conf info 1

Both of these variations specify an alternative configuration file -- I 
need this facility to be able to run them in the tests.


If this doesn't help, then build and use the debug versions. To build a 
debug bbstored, do

	cd bin/bbstored
	make

(make defaults to debug version in the module directories)

Then use the bbstored exe from debug/bin/bbstored to test things. You 
should get more helpful error messages.
