NTP on Pix 501

[pdpmail]

Purely lab purposes - Pix 501 and 6.3 OS - What is best way to setup NTP on a Pix 501 ? Can I use an Dell XP PC clock as a time source - and how do I do this ? (I have an XP PC linked to Internet getting time check once a day from Atomic clock). Thanks in advance for guidance - Peter pdpmail@aol.com

I have found 2 ways :

Method 1

-------------

[no] ntp authenticate

[no] ntp authentication-key number md5 value

ntp server ip_address [key number] source if_name [prefer]

no ntp server ip_address

[no] ntp trusted-key number

clear ntp

show ntp

show ntp associations [detail]

show ntp status

Method 2

------------

!Find a external NTP source a.b.c.d

ntp server source outside

ntp server source outside

replace w/ the IP address of the NTP source.
