Troubleshooting NCP Packet Signature
This section describes some solutions to problems that might be associated
with using NCP packet signature.
Client Workstations Are Not Signing Packets
Client Workstations Cannot Log In
Problem Client workstations are not signing NCP packets.
Solution The SECURITY.VLM file is not loading. Ensure the signature
level on the client workstation is not set to 0.
SECURITY.VLM loads by default when the client signature
level is set to 1, 2 or 3.
Use the VLM /V4 command line parameter when
loading the VLM software to display load time
information.
Problem Client workstations cannot log in.
Solution Make sure the packet signature levels on the server and the
client workstation are correct. See “Effective Packet Signature
Levels”.
Note that the following situations do not allow logging in:
• Server packet signature = 3, client workstation signature = 0
• Server packet signature = 0, client workstation signature = 3
• The LOGIN utility is an older version that doesn’t support
packet signature
• The NetWare DOS Requester or the shell is an older version
that doesn’t support packet signature
