Please Gudie How I can install and configure stun sever in mandrake(Linux)
ok, whatever you say ! 
did you bother searching for this ? sourceforge.net/projects/stun/ would be a good place to start. as for guidance on installing/configuration, shouldn’t you be asking the people that support it ?
this is the Asterisk users forum, it doesn’t follow that support for every application on every OS is available here. hopefully someone will be along to help you, but i think you could start by helping yourself and reading a few pages first.
