NTPDATE - Help please

[Court Campbell]

Have a network admin open udp port 123 to the server(2) where you are going to get time from. Also, have you thought about using a local server on your same network for time?

[Court Campbell]

That should have been server(s).

I discover what happen.
There is a firewall blocking any external site that i try to ping:

[root@lab1 ~]# ping www.uol.com.br
PING www.uol.com.br (200.221.2.45) 56(84) bytes of data.
From router-virtual.sao-paulo.axalto.com (172.27.109.3) icmp_seq=1 Packet filtered
From router-virtual.sao-paulo.axalto.com (172.27.109.3) icmp_seq=2 Packet filtered

They tell to me that i can't enter in any external site.

Is there anything i can do to solve this problem ??

Or just who have access to this firewall can do something??

thanks!

what local server?
i have problem with the host and the vmwares, the time is always different.
So, my idea is configure a ntpdate in host, and the vmwares get the same time.

>> what local server?

Umm, a server that you have available to pull time from. Prefereably the vmware host at this point.

>> i have problem with the host and the vmwares, the time is always different.

If I remember corecctly there is an option in vmware guests to get their time from the host.

>> So, my idea is configure a ntpdate in host, and the vmwares get the same time.

You wouldn't configure ntpdate. You would setup and configure ntpd.

Hm... do you know where is this option?

>>>You wouldn't configure ntpdate. You would setup and configure ntpd.

It's been awhile, but I would start here:

Hi,

If you can't get out to the real world to interrogate an NTP server, you either need to find one that already exists on the internal network, or configure one of your machines to be an NTP server.

You might find that your network people have got NTP running on your routers or firewalls, that you can point your machines at.

If not, then you need to make one of your machines the master NTP server, and then point all of the other machines at it. It doesn't really matter to VMware if the real time isn't used, just that all the machines have the same time...

Hope this helps,

Regards,

Rob
