fedora livecd-creator unmount issues

mkhan — Wed, 14 Apr 2010 19:02:49 +0000

While building with livecd-tools (livecd-creator) in Fedora 12, I ran into an issue where it will error out b/c it is unable to unmount. It returns a error message including:

umount: /var/tmp/imgcreate-eNHsQm/install_root: device is busy.
        (In some cases useful info about processes that use

I have managed to work around this by reviewing a couple of issues logged in bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=501334

ESXi console / cli

mkhan — Mon, 01 Mar 2010 08:28:33 +0000

ESXi has a console. Easy to google and find instructions on how to access it.

It is also possible to enable SSH server to allow remote login to the console.

You can then register vms, format partitions as vmfs and perform other operations using vim-cmd, vmkfstools, or esxcfg-* commands.

Nokia N810 Wimax Edition

mkhan — Sun, 03 Jan 2010 23:37:47 +0000

The Nokia N810 Wimax Edition is a neat little device.

It runs a linux-based OS called maemo, and is able to connect via various means including Wimax and Wifi.

It runs a firefox-based browser and has a built in google talk and SIP client. It is also possible to install Skype. This means you can have a handheld device w/ relatively inexpensive Wimax service and be able to make calls to landline/cell phones using VOIP.

I procured this device for a fraction of its original MSRP via e-bay and was able to connect to Clear Wimax service in the Austin area. I am getting speeds of around 4mpbs down and .5 to 1 mpbs up on this device.

I intend to poke around and see if I can make the device a wifix hotspot for the Wimax connection, usb/bluetooth tethering, etc.

Thus far two issues I have seen with the device and/or the service:

Clear service is not as widespread as 3G in Austin… Within my house, some areas are great, others are spotty. I experienced the same driving around town.
The device doesn’t seem to seamlessly transition between Wimax towers like my 3G devices do.. It will lose signal and drop the internet connection, prior to picking up another tower. Until this is addressed, it will not be possible to maintain a VOIP phone conversation while driving.

cygwin in windows domain environments

when you log into cygwin you will be prompted to generate an /etc/passwd and /etc/group file… however in large domain enivornments with tons of users and groups, this can take a long time or even hang.. here is a procedure to get this to work:
