I have nearly finished filling out the MIB tree for SNMP. What gaps
are left involve data I do not know how to get:<br>
<br>
* Time Resolution (not to be confused with Time <i>Precision</i>,
which is one of the first entries I implemented)<br>
<br>
* Time Distance<br>
<br>
* Validation for the TestSet sequence. According to the RFC this is
one of the most complicated parts of an agent to get right.
Currently it is setup to be failsafe, which we can get away with for
now because the NTP MIB only has two writable entries, and simple
ones at that.<br>
<br>
* Check if ntpd configuration changed. The description listed in the
RFC is: "The notification to be sent when the NTP configuration has
changed, e.g., when the system connected to the Internet and was
assigned a new IP address by the ISPs DHCP server.". But I do not
know the full extent of what to check, or how to do so.<br>
<br>
There are other issues, but they mostly have to do with refactoring
and robustifying the code. The ones I am listing here require input
from someone else.<br>
