Wireshark-users: [Wireshark-users] MySQL packets showing "unknown/invalid protocol"

Hi,

I am using Wireshark to try to analyze some MySQL database traffic on a
remote network behind a firewall.  I have used tcpdump to get a file
which I then open in Wireshark for analysis.

I'm using Wireshark 0.99.4 (downloaded and installed yesterday) and
MySQL 5.0.24.

In the request packets from the client, I can drill down to MySQL
Protocol > Command and see, for example, "SELECT * FROM foo".  In the
response packets, however, no data is displayed - I've pasted an example
below.

Is the MySQL protocol ... plugin, I guess ... unfinished?  Did MySQL
change their API in version 5?  I haven't tried installing a 4.x version
locally and sniffing that traffic.  Might I have used some tcpdump flag
that's changing my data enough that Wireshark doesn't understand it?

I have searched all the wireshark docs I can find, and googled
unsuccessfully for "wireshark mysql" and variations.  Any ideas on this,
or suggestions for further research are much appreciated.

Thanks,
Rachel
