Figure 12-2 illustrates that OES 2 and NetWare 6.5 servers can freely interchange time
synchronization information because NetWare 6.5 includes the following:

A TIMESYNC NLM that both consumes and provides NTP time packets in addition to
Timesync packets.

An XNTPD NLM that can provide Timesync packets in addition to offering standard NTP
functionality.
NOTE: Although NetWare includes two time synchronization modules, only one can be loaded at a
time.
Figure 12-2 NTP Packet Compatibilities with All OES Time Synchronization Modules
Compatibility with Earlier Versions of NetWare
Earlier versions of NetWare (version 4.2 through version 6.0) do not include an NTP time module.
Their time synchronization options are, therefore, more limited.
NetWare 5.1 and 6.0 Servers
Figure 12-3 illustrates that although NetWare 5.1 and 6.0 do not include an NTP time module, they
can consume and deliver NTP time packets.

NetWare 5.0 and 4.2 Servers
Figure 12-4 illustrates that NetWare 4.2 and 5.0 servers can only consume and provide Timesync
packets.
