NCP Packet Signature Options
Because the packet signature process consumes CPU resources and slows
performance both for the client and the NetWare server, NCP Packet Signature
is optional.
Several signature options are available, ranging from never signing NCP
packets to always signing NCP packets. NetWare servers and Novell clients
each have four settable signature levels.
The signature options for servers and clients combine to determine the level
of NCP Packet Signature on the network.
You can choose the packet signature level that best meets both your system
performance needs and network security requirements.
NOTE: Some combinations of server and client packet signature levels can slow
performance. However, low-CPU-demand systems might not show any
performance degradation.
Effective Packet Signature
The NCP Packet Signature levels for the server and the client interact to create
the effective packet signature for the network. Some combinations of server
and client levels do not allow logging in.
The following figure shows the interactive relationship between the server
packet signature levels and the client signature levels.
