Sure. In its current incarnation it's a Python script using a pcap
module I found in some package that I can no longer identify.... It's
also quite tied to my current file structure, though some of that also
has to do with the earlier assumptions I made about filehandles.
The biggest challenge for general usage is the inode -> pathname
translation. In my case there are currently about 900 files I can look
up before the packet capture starts, and cache those inode numbers. A
general utility will require a different solution, starting with the
existing method of snooping getattr and other calls. Any other
suggestions on how I can generically convert inodes to pathnames without
massive overhead?
Once I have my current code doing what I want I'll clean it up and post
it here so it can be hacked into a useful tool.
