NTPDATE - Help please

what is lab1? Is it a guest or the host? And is this esx server?

>>>what is lab1? Is it a guest or the host? And is this esx server?

lab1 is the host.

no... is a HP DL 380 server with Red Hat.

[BiancaP.]

i am sorry.... i have vmware server

[Court Campbell]

on lab1, check that that the firewall isn't creating the issue. you can run

# service iptables status

to see if it is running, if so run

# service iptables stop

If you want to run the firewall you will need to edit the firewall rules to allow udp port 123 outbound. And then run "service iptables save". Otherwise you can turn off the firewall at next reboot by running

# chkconfig iptbales off

But, I'll leave that decision to you.

[Court Campbell]

I've been looking through the responses and I am curious if you have your network properties setup on lab1 correctly. Maybe you fat fingered the netmask, or gateway, or something. You might start there next if the firewall is not the issue.

Thank you!! =)

>> If you want to run the firewall you will need to edit the firewall rules to allow udp port 123 outbound

How can I do this??
I don't know...

I think the second thing you mencioned is ok:

I don't create rules that often, so I usually end up googling for examples. Here is just one of many you can test out.

Also, you can install and use firestarter. That may actually be easier.

in regards to your thanks, is your issue resolved?

[Court Campbell]

I will say that I find it interesting that you have both eth0 and eth1 set to use the same ip address.

[BiancaP.]

I put the rule:
iptables -A INPUT -s 172.27.109.56 -p udp --dport 123 -j ACCEPT

And try again... but i get the same problem... =/

I discover that ntptime dind't work too:

[root@lab1 ~]# ntptime

Do you have both ports eth0 and eth1 connected to your network? If so, I would suggest disbling one of them and getting rid of the duplicate ip configuration. I more think that is the issue than anything else at this point.
