Server Operating System Administration Guide
To determine the server's current signature level, enter the following
command at the System Console prompt or view the setting using
NetWare Remote Manager:
SET NCP Packet Signature Option
To set a server's packet signature level, enter the following command at
the System Console prompt or change the setting using NetWare Remote
Manager:
SET NCP Packet Signature Option = number
Replace number with 0, 1, 2, or 3. The default is 1.
For example:
SET NCP Packet Signature Option = 2
Number Explanation
0 Server does not sign packets (regardless of the client level).
1 Server signs packets only if the client requests it (client level is 2 or
higher).
2 Server signs packets if the client is capable of signing (client level is
1 or higher).
3 Server signs packets and requires all clients to sign packets or
logging in will fail.
To ensure that the signature level is set each time the server is brought up, you
can add this SET parameter command to your STARTUP.NCF file
You can also use the SET parameter command to change the signature level
from a lower to a higher level or use NetWare Remote Manager.
You cannot change from a higher to a lower level unless you first reboot the
server. For example, if the current signature level is 2, you can't set the
signature level to 1 by using the SET command at the console. To change the
signature level from 2 to 1, you must add the SET command to the
STARTUP.NCF file and then restart the server:
