System time is one hour ahead of ntp server :AIX

Problem : System time is one hour ahead even ntp sync is proper.

Observation: I stoped the ntp client and set the time manually using date command .The moment i do an ntpdate to the time server system time jumps to one hour ahead.All other ntp clients were fine and were showing proper time.So this should be a problem with this particular client.

Client OS details: AIX 7.1

From the problematic client:

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

bash-4.2# date

Mon Mar 17 19:51:33 IST 2014           =>Time showing 19:51 which was 1 hour ahead that of  ntp server.

bash-4.2# date 031718512014             =>Set time manually.

Mon Mar 17 18:51:33 IST 2014          

bash-4.2# ntpdate  192.168.1.100             where 192.168.1.100 is my ntp server.

17 Mar 19:51:34 ntpdate[12386500]: adjust time server 192.168.1.100 offset  3600.479108

Please notice time is getting set to one hour ahead.

bash-4.2#date

Mon Mar 17 19:51:35 IST 2014

IST  word at the date command output gave an impression that Time zone is IST(GMT+5:30). But it was not true when checked the time zone.

bash-4.2# echo $TZ

IST-5:30IST

So changed the time zone to Asia/Kolkata(GMT+5:30) using smitty and restarted the system to effect the new Time zone.

smitty-->System Environments-->Change / Show Date and Time-->Change Time Zone Using System Defined Values-->Select Asia/Kolkata from the list-->Enter-->Enter -->Exit (F10)

Then took a reboot.

bash-4.2# shutdown -Fr

Once the system is back everything will be fine.

An event was unable to invoke any of the subscribers:virtual router

Problem: Error message while starting Virtual Router "An event was unable to invoke any of the subscribers"

Reason: The problem happens when the Virtual Router isn't closed properly (ie when your connection disconnects or your computer locks up and needs to be restarted). The shared internet connection still has a lock on the share Virtual Router created, and so it can't create a new one.

In my case i have two  internet connections earlier i was using a data card which was shared and virtual router was using it .once the laptop woke up from hiberation i tried to connect via lan connection ,as the lock from data card was still there i ot into this issue.

Solution:
In Windows 7

Go to your Network and Sharing center -->Change adapter settings. Select the Internet adapter whose Internet connection you share with other devices.

Go to Internet Sharing. Break the lock on the old share by setting the adapter to share its connection with something else (whatever you have handy; network adapter, wireless, anything). You'll get a warning about the old share still being in effect. Break the old share, click OK until the settings for your adapter closes.

Open up your adapter's settings again, and remove the shared connection you just created. Keep clicking OK to close the adapter's settings.

Start up Virtual router again, and enjoy.

This isn't a problem specific to Virtual router, any similar app you try won't be able to create a share until you break the old one that Virtual router had.
