Hi All,
I've been playing with NTP authentication between three routers, one as
master the other two as clients but one of the clients has been
configured with a bad key.
Now I have set debug ntp auth and packet to check out what happens .
Now what i see is that the server attempts to use key 1 but doesn't say
success or fail but when it replies to the client who is using the bad
key it doesn't send it using a key.
Is this the masters way of saying authentication failed but here's my
time anyway?
BTW it's only been 10 minutes so they haven't synched yet at all.......
