Wesley's Tool-Box

Moving to the new home in Naju will be completed on November 25, 2014, and that includes moving the server equipment as well. As such, the website will be offline on that day, but I will try to minimize the downtime if possible. I hope the internet connection will be good.

Seeing that there weren't much show-stopping problems with OS X Yosemite 10.10.0, I decided to proceed with updating my Mac mini server's OS from OS X Mavericks 10.9.5. Experiences with the Mountain Lion - Mavericks update helped in getting the web server back up running again relatively quickly. The downtime was only about 2 hours. Not much of a drama to write about.

One problem I noticed is that MySQL does not automatically start on reboot, and it seems to be a known problem. I'll have to remember to manually restart it when I have to reboot the server.

I've reported about the server losing connection after a bit of idling time yesterday, and the culprit was the power management settings. Surprisingly, my Mac mini was set to go into power saving mode just ten minutes after idling. I'm not sure what kept it up before, but it certainly isn't kept awake now. So I set the setting to never go fall asleep. Now the connection doesn't drop.

I thought this was the end of troubles, but it turns out that the server now takes a long time to respond after several minutes of idling. Once it responds, subsequent pages load just fine. I haven't found out why this was the case, but I know it's not a DNS lookup issue because there's no delay while there is network activity on the Mac.

So I devised a way to work around this issue by automatically causing a small network activity every minute. After opening Terminal:

crontab -e

[Press "i"]

00-59 * * * * /sbin/ping -c 1 -n google.com > /dev/null/

[Press "Esc" button]
[Press "!wq"]

And that's it. Once this is done, the system starts doing a ping once every minute silently. So far, it's working nicely and the website loads fine regardless of idling time.
