Thanks, unfortunately I lose the ability to access mime type with that function.  Therefore I think I'll stick with file_sniff.  Get errors saying f$info$mime_type isn’t present.  I’ll keep playing with it when I can.  Thanks again for Bro, incredible tool to have.

Hi Brian,

you should be able to just use the event file_over_new_connection, which
includes the connection record. With that, you don't have to loop over
complex data structures and can just use Site::is_local_addr.

This would probably look similar to:

event file_over_new_connection(f: fa_file, c: connection, is_orig: bool)
    if ( is_orig && Site::is_local_addr(c$id$orig_h) )
                Files::add_analyzer(f, Files::ANALYZER_EXTRACT);

I hope this helps,
