checking clock value on Meeting Place Express

Hi guys,

Is there a way to check the value of the system clock, and whether it is synchronized with NTP?

I configured NTP with "net" CLI command, with root privilege of course. Then I rebooted the appliance. However, on the Cisco Wiki, I found no indication of a CLI command to check the result.

any idea?

Hi Wass,

You can use "ntpq -p" command to check if you MPX is synchronized with NTP server (you need to be logged in as root to MPX CLI in order to run this command.

"date" will show the current date and time on the MPX server.

Re: checking clock value on Meeting Place Express

thanks Natasa for the input. Problem solved.

I'd like to share what I did. Here's the output from the MPX CLI:

[root@TNSVMPCS01A6 root]# date

Wed Nov 30 08:57:24 CET 2011

[root@TNSVMPCS01A6 root]#

[root@TNSVMPCS01A6 root]#

[root@TNSVMPCS01A6 root]# ntpq -p

     remote           refid      st t when poll reach   delay   offset  jitter

==============================================================================

*10.100.254.1    CHU_AUDIO(1)     8 u   51   64   77    1.857  8734905   0.922

LOCAL(0)        LOCAL(0)        10 l   56   64   77    0.000    0.000   0.004

[root@TNSVMPCS01A6 root]#

As you can see, MPX "seems" to synchronize its time with 10.100.254.1- which is the NTP server. However, "date" command shows a wrong date.

Here's a "debug ntp packet" issued on the NTP server:

I had to reboot MPX and wait a couple of minutes to see it synchronized:

[mpxadmin@TNSVMPCS01A6 mpxadmin]$

[mpxadmin@TNSVMPCS01A6 mpxadmin]$ date

Wed Nov 30 09:11:37 CET 2011

[mpxadmin@TNSVMPCS01A6 mpxadmin]$

[mpxadmin@TNSVMPCS01A6 mpxadmin]$

[mpxadmin@TNSVMPCS01A6 mpxadmin]$

[mpxadmin@TNSVMPCS01A6 mpxadmin]$

[mpxadmin@TNSVMPCS01A6 mpxadmin]$ date

Thu Dec  1 09:31:51 CET 2011

[mpxadmin@TNSVMPCS01A6 mpxadmin]$

Hi Wass,

It shouldn't take that long to sync. Could you please try the following:

- Login as root and stop MPX application: "mpx_sys stop"

- With "net" command make sure that NTP server is set correctly

- Verify that ntp deamon is running: "ps -ax | grep -i ntpd"

- Stop the ntp deamon: "/etc/init.d/ntpd stop"

- Manually sync time with NTP server: "/usr/sbin/ntpdate -s ntp-source-ip"

- Start ntp deamon: "/etc/init.d/ntpd start"

- Reboot the server: "reboot"

- After the server is up, check if the date/time is correct: "date"

- Verify that ntpd will start after a reboot: "/sbin/chkconfig --list ntpd"

You should see:

ntpd            0:off   1:off   2:on   3:on    4:on   5:on    6:off

- If they are all set to off, then set ntpd to start during startup "/sbin/chkconfig ntpd on"

HTH,

Natasa
