Apple hasnât shipped Samba as part of OS X since 10.6, quite a few years ago now.  In 10.7, they switched to an internally-developed SMB server.

The build of Wireshark on the machine Iâm using right now has about 1,700 protocol dissectors, which covers pretty much every protocol youâve ever heard of, and hundreds you havenât.

The trick is, dissecting the packets is only useful if the protocol is human readable (SMB isnât) or you know the protocol (I donât) or youâre lucky and happen to see something you can make sense of.  I was hoping not to have to rely on blind luck.

I guess Iâm not seeing what values to pass to CreateFile() because I get an error with the values Iâm trying here.  Iâve put my fleshed-out test program here:

Its complaint is:

  Bad handle: The filename, directory name, or volume label syntax is incorrect.

I double-checked, and P: is still mapped.
