NTPv4 : findexistingpeer() considers mode.
Hi Experts,
Could you please help me in understanding the difference between the
findexistingpeer() in NTPv3 and NTPv4. In NTPv4 the findexistingpeer()
additionally check the mode too. Why is this so ? This could allow
two different associations for a same server with different mode, right
?
Could you please explain the reason for this change, if any ?
Thanks,
Arul Kumar C

Arul,
This was a deliberate choice to avoid interaction between misconfigured
conditions. Consider what happens if some perp configures peer and
client associations with the same server. Formerly, this was really bad
news; now it actually works, even if ill advised.
