Can some one please explain me the meaning of 'SMB Trans2 ' request and
response.
SMB's "transaction" mechanism is used to implement requests and
responses that could transfer more data than the limited amounts some
mechanisms over which SMB is sent allow in a single packet.
Several different types of operations, including the operations that
scan directories and return information about the files and
subdirectories in that directory, use the "transaction" mechanism. The
directory-scanning operations are probably the most frequently seen
operations that use the "trans2" request, and:
Subcommand: QUERY_FILE_INFO (0x0007)
...that's probably what the Trans2 request you sent is (you'll probably
see "find first" or "find next" (perhaps all capitalized, and perhaps
with underscores or nothing between "find" and "first" or "next") in the
dissection of those requests.
If the time between the request and the response is large, this might be
a problem with the server - scanning a large directory might be slow.
What operating system is the server running and, if it's some flavor of
UN*X (commercial UN*X including Mac OS X, Linux, some flavor of BSD), is
it using Samba and, if so, what version of Samba is it using?
