RE: determining the host from which a file IO request originated in a file system filter

Not sure that gets me what I’m looking for - the name of the host on which the IO originated. I think I’m going to have to look upstream a bit, if I decide to pursue this. Perhaps to the CIFS implementation…

(Must’ve missed the original question)
How about the user name itself? \Domain\Server\Share - that gives the Server
name, which is enough.

Anyway, taking identification a step further, in the case of file IO
coming in through the file server, should it be possible to determine
the remote host from which a particular file IO originated? IIRC, all
remote calls would come in in the context of the SRV service (or
something like that) so that was a clue that it was coming in through a
non-local user. Should it be possible to determine the network address of the host
on which the file request was initiated? Or would I need to filter some at some
higher level - up in user land, somewhere?
