Advanced Unix material?

[John Antypas]

Does anyone out there know of an answer to tthis?  I have been working with
Unix (BSD aand Sys V) for some time now and am quite comfortable with it.
I am quite comfortable with C as well.  Where does one go to get the advanced
material on Unix? (protocals, sockets, i-nodes, etc.).  I am tired of seeing
Unix materials teaching me C again.
