I have setup a software in linux ...and want to give the server to
the client .
But the problem is that ...if the client copy my hdd ...then i will
lose a large amount of money .
It is not in php so i cannot encode it

It has some conf files that can be read by any editors(ie,vim).
I want a way so that ...even if they copy my hdd they cant read or
change the configuration.
Is there any other solution ? and wat is the best software(opensource)
that can do the job .

My os is debian4/centos4.5/5.

Please help. Thanks .
