HP CIFS Client A.02.02 Administrator's Guide

Introduction to the HP CIFS Client
HP CIFS Client Features
Chapter 118
In order to provide HP CIFS Client AutoFS support, AutoFS 2.3 must be
installed and configured on the system. For detailed information on
installing and configuring AutoFS, please refer to “Configuring and
Administering AutoFS” in NFS Services Administrator’s Guide on
HP-UX at http://www.docs.hp.com.
NOTE Automounting a CIFS filesystem using the HP ONC+ AutoFS service is
only supported on HP-UX release 11i v1 and v2. If you have the HP-UX
11i v1 system, you must install the ONC software package, Enhanced
AutoFS, available at http://software.hp.com to enable the AutoFS 2.3
support. AutoFS doesn’t support HP CIFS Client on HP-UX release 11.0.
Support for Internationalized Clients
The CIFS Client is designed to work with a variety of internationalized
clients and servers. It can use Unicode to transmit multi-byte characters
on the network, or any of several character encoding tables located in
/etc/opt/cifsclient/unitables. See the README file in that directory for
an index of the tables.
NTLM, NTLMv2 Password Encryption
NTLM is a challenge-response protocol. The server sends a challenge key
to the client which the client returns to the server encrypted with the
user’s password. The server performs the same encryption and verifies
that the client’s request matches. No semblance of the user’s password is
transmitted over the network. The CIFS Client supports NTLM and
NTLMv2. NTLM verison 2 (NTLMv2) uses the same challenge-response
protocol, but it provides more sophisticated encryption algorithms than
NTLM, and hence better password protection.
Packet Signing
The purpose of CIFS packet signatures is prevention of man-in-the
middle attacks: the client and server are mutually assured of the other’s
identity by requiring a unique signature on each SMB packet.
