As always, googling found the answer to my problem, and to save myself having to look for it again, I figured I’d document it here.

Open a terminal window and:

hdiutil convert /path/to/mac_image_file.dmg -format UDTO -o /path/to/standard_image.iso

How to use a Netgear WGR614 wireless router as a bridge

WGR614The short answer, don’t plug your uplink into the internet slot, instead plug it into one of the four internal ports. This page on Netgear’s web site does a so-so job explaining, but the diagram is pretty good.

Before you do this, make sure you’ve configured the LAN IP of your WGR614 to be a member of your IP network, preferably with a Static IP rather than as a DHCP client, so you can find the device later should you want to admin its setup.  Technically though, that’s not really necessary as a network bridge will simply pass the traffic regardless if it is addressable or not!  This can make your Access Point very secure by only being addressable on another logical IP network (although security through obscurity is probably not the only thing you should rely on).  Also, don’t forget to deactivate the built-in DHCP server, unless you actually want to use it in which case make sure your DHCP scope is consistent with your existing network and doesn’t overlap with the scopes of other DHCP servers… but if you’ve read this far and know what I’m talking about, you probably knew that.  We can simply ignore the WAN setup since it’s not at all used.

If you’re at all curious why I did this, here’s the full story…

Some thoughts drinking wine

To my friends who enjoy a glass of wine, and those who don’t.

As Ben Franklin said:
In wine there is wisdom,
In beer there is freedom,
In water there is bacteria.

In a number of carefully controlled trials, Scientists have demonstrated that if we drink  1 liter of water each day, At the end of the year we would have absorbed more than 1 kilo of Escherichia coli, (E. Coli) -the same bacteria found in feces.

In other words, we are consuming 1 kilo of poop.

However, we do NOT run that risk when drinking wine & beer (or tequila, rum, whiskey or other liquor) Because alcohol has to go through a purification process Of boiling, filtering and/or fermenting.

Remember:
Water = Poop,
Wine = Health.
Therefore, it’s better to drink wine and talk stupid,
Than to drink water and be full of sh!t.

There is no need to thank me for this valuable information: I’m doing it as a public service!

Disconnecting from a stale NFS

While monkeying around with my little test lab, I swapped one NFS server out and put a new one in. I expected mounts to be flaky and need to be reconnected. However, when I got on the Linux machines that had the swapped filesystems mounted, I got all kinds of errors like “cannot stat” etc.

The key to fixing this is first and foremost to cd /. and get out of that folder. Then run lsof. You might want to try lsof |grep foldername of the mount point. Then you can kill -HUP the process ID and voila! Done!

I struggled with this issue for the millionth time and figured I’d document it myself rather than having to troll the internet to find the answer (which I found here).
