|
|
| |
NetWare Services |
| NWP, the NetWare protocol multiplexor, handles each particular | |
NWP.VLM |
| network implementation through these child VLM programs: | |
|
| • BIND.VLM for NetWare 2 and NetWare 3™ bindery servers | |
|
| • NDS.VLM for NetWare 4™ NetWare Directory Services™ | |
|
|
| servers |
|
| • PNW.VLM for Personal NetWare™ (NetWare desktop) servers | |
|
| The NWP services also include logins and logouts, broadcast | |
|
| messages, and establishing and destroying connections. | |
|
|
| |
Security Services |
| RSA (Rivest, Shamir, and Adleman, developers of this particular | |
RSA.VLM |
| public key encryption system) provides | |
|
| authentication for the workstation. | |
|
| NetWare uses this encryption system to strengthen user | |
|
| authentication and access control functions. | |
|
|
| |
File Services |
| FIO, the file input/output module, is a | |
FIO.VLM |
| implements a basic | |
|
| noncached read/write, burst | |
|
| internet packet read/write. | |
|
| The Packet Burst™ protocol in FIO.VLM is based on Open Data- | |
|
| Link Interface interconnectivity strategy and is referred to as PBODI. | |
|
| This functionality allows users to choose performance over memory | |
|
| use and vice versa. | |
|
|
| |
Print Services |
| The PRINT module provides printing services using the FIO module | |
PRINT.VLM |
| for its file writes. Print redirection is handled in the following ways, | |
|
| depending on entries in the NET.CFG file: | |
|
| • | Noncached |
|
| • | Cached |
|
| • Via Packet Burst protocol to the server | |
|
| • Via File Services (FIO) | |
