Metasploit Framework

Msf::Exploit::Remote::SMB::Client#smb_open

the default chunk size of 48000 for OpenFile is not compatible when signing is enabled (and with some nt4 implementations)
cause it looks like MS windows refuse to sign big packet and send STATUS_ACCESS_DENIED
fd.chunk_size = 500 is better
