Agreed. I think this can and should be accomplished by plugging together<br>
three components:<br>
<br>
(1) the Mode 6 Python client code I wrote to replace ntpq with.<br>
<br>
(2) The Python SNMP library<br>
<br>
(3) The Python socketserver library<br>
<br>
I don't think this will be difficult - I'd actually be surprised if a<br>
basic SNMP daemon made from these pieces runs much over 100 LOC and<br>
I'm pretty sure I could write and test it in a day. Data flow: when<br>
you access an SNMP resource at the daemon, this gets translated to a<br>
Mode 6 query, with the response updating the MIB and posted back to<br>
your SNMP client.<br>

<br>
There's an SNMP trap feature. I could speculate further but I don't think<br>
there's much point to doing so before we have evidence of some user demand.<br>
