Working with three timezone

Working in a company with a client in another timezone is a challenge. I’ve scheduled a migration of a service from one of my clients and miss schedule!

The results of the meeting we decided to migrate on Tuesday at 22:00 with timezone PST. And on the day Tuesday at 12 pm WIB, so I was ready to migrate client service. After I’ve been waiting for, the client is not online, it turns out Tuesday at 12 pm WIB is equal to Monday 10 pm PST.

So the correct time is Wednesday at 12 pm WIB. So here’s a tips. Put your clients timezone on your computer. Here’s a screenshot of 3 timezone on my office computer.

How to allow Named/bind9 to write to other directory that blocked by Apparmor

My slave dns server returned error while I tried to add another domain, below example of the error.

kernel: [1239217.411031] type=1503 audit(1309700303.423:12381):
operation="mknod" pid=1692 parent=1 profile="/usr/sbin/named"
requested_mask="c::" denied_mask="c::" fsuid=109 ouid=109

That’s because named aren’t allowed to write to directory /etc/bind/db/in. To solve this issue, open apparmor profile of named (/etc/apparmor.d/usr.sbin.named), add this line right after ‘/etc/bind/** r,‘ :

/etc/bind/db/** rw,

Restart the apparmor and then restart named.
