NTP Times 2

[Almin]

Hi All,

How can I get this NTP stuff to work. I took a position for some guy that has previously configured this and left if broken.

ntp logging
ntp authentication-key 2 md5 04753F363B345E400C0B09 7
ntp authenticate
ntp trusted-key 2
ntp source FastEthernet0/0
ntp update-calendar
ntp server 63.241.206.60 key 2 prefer
ntp server 63.241.206.61 key 2
ntp server 108.61.73.244
end

c1841_TACACS_2#                 sh ntp status
Clock is unsynchronized, stratum 16, no reference clock
nominal freq is 250.0000 Hz, actual freq is 250.0000 Hz, precision is 2**24
reference time is 00000000.00000000 (00:00:00.000 UTC Mon Jan 1 1900)
clock offset is 0.0000 msec, root delay is 0.00 msec
root dispersion is 62.36 msec, peer dispersion is 0.00 msec
loopfilter state is 'FSET' (Drift set from file), drift is 0.000000000 s/s
system poll interval is 64, never updated.

c1841_TACACS_2#sh clock
14:58:21.971 UTC Tue May 1 2012
c1841_TACACS_2#

when I do show ntp status I get (00:00:00.000 UTC Mon Jan 1 1900) and this is the reason that I cant authenticate this perticualr device with our Cert router. We dont have our own ntp server so im not sure how to go about this?

Does anyone know how to fix this issue?
Thanks

you need to verify that the NTP servers listed there a) are still in existence, and b) use the same authentication key that is configured.

Those are some public NTP servers, how can I figure out what the authentication for those will be?

Thanks

If they are public then its unlikely they use authentication.

You will have to do a little troubleshooting using ping and traceroute and see if those devices are still valid and where they are .
