can you make a unix socket secure?

[Karl Hakimian - staff]

I need to know how to secure a unix socket. That is I need to be able to tell
who is connecting to it so that I can close the socket if I don't want to talk
to a particular person. How is this done? With inet sockets you can check to
make sure that the socket was opened on a reserved port is there anything like
this for unix sockets?

Please reply with email. If this is not a dumb question and people are interested
I will post a summery. Thanks
