Hello,

Some time ago I reported a bug in the implementation of
AutoKey+IFF, in ntp ver 4.2.4p8.
The error is intermittent and has been observed a in the long
run of ntpd, that is within 2 - 10 days.

When the error happens, ntpd keeps on running but authenticated
server is rejected:

 ntpq -p
     remote           refid      st t when poll reach   delay   offset 
jitter
====================================================
 neptune         .CRYP.          16 u   6d   16    0    0.000    0.000 
0.000
*ntp2.tp.pl      .ATOM.           1 u   15   64  377    2.522    0.008 
0.088

 ntpq -c associations
ind assID status  conf reach auth condition  last_event cnt
===========================================
  1 60684  e0fe   yes   yes   ok     reject             15
  2 60685  9614   yes   yes  none  sys.peer   reachable  1

Client synchronizes successfully to the another server which is
in the configuration file.
Server with the authentication is not used any more, "reject"
status seems to be permanent (unless ntpd is restarted).

The only hint is in cryptostats logfile:
 ...ntpkey_IFFkey_xxx.tpnet.pl.3479706582 mod 384
 ...error 10e opcode 82070000 ts 3505303563 fs 3479706582

What is a meaning of error 10e opcode?
Has someone encountered such a problem in the longer run?

I appreciate your help.
Jacek
