.rpc_door, what is that?

[James Kelty <james () TUNA ORG>]

Hello,

Yesterday I was wondering around on one of my systems when I noticed
something I hadn't seen in the /tmp filesystem before.
Does anyone know what a directory called .rpc_door would be doing in the
/tmp filesystem?  There are also three subdirectories with a capitol
"D" for file type. What is the capitol "D" for?

I am including a typescript file from the system.

Just incase you wanted to know, this system is Solaris 7 running on x86.

Thanks!
