Often SAN/iSCSI storage is zoned between multiple Linux systems to be used for migrating data, high-availability, etc.
What I commonly see, however, is the tendency to try to mount this storage on all systems, at the same time — this is a no-no. In fact, it’s not enough to just not [...]

Amazon EC2 now offers Micro Instances
September 9, 2010 – 9:02 am
I am pleased to find that Amazon’s EC2 service now offers a “Micro” sized instance. According to Amazon:
“Micro instances provide 613 MB of memory and support 32-bit and 64-bit platforms on both Linux and Windows. Micro instance pricing for On-Demand instances starts at $0.02 per hour for Linux and $0.03 per hour for Windows.”
This puts [...]
Determining if your kernel and hardware is 32bit or 64bit
June 13, 2009 – 11:07 am
I’m often asked by end-users, developers, and fellow system administrators, how to determine if the installed OS is 32bit or 64bit. I’m also asked if the hardware is capable of 64 bit, 32 bit, or both. Here is how to tel by OS:
HPUX
# getconf KERNEL_BITS
64
This will tell you if your currently running kernel is 64 [...]
Ubuntu 9.04 Release Candidate now Available.
April 21, 2009 – 7:12 pm
I’m a big fan of Ubuntu and I’m excited for the new 9.04 RC release. Keep in mind this is a “for testing only” release. Currently I run Ubuntu 8.10 for my main desktop in my home/office. I’m generally late to upgrade and prefer to play with new releases in a Virtual Environment (or, [...]
COTD: fuser - identify processes using files or sockets
April 20, 2009 – 7:44 am
Today’s Command Of The Day is the “fuser” command.
Have you ever wanted to unmounted an NFS share, or local filesystem and couldn’t because it was in use? The same applies to CD/DVD’s, PenDrives, etc. Generally, you receive a message similar to the following:
# umount /dev/sdc1
umount: /media/disk: device is busy.
The fuser has many options. The ones [...]
Firefox 3.0.7 Available
March 5, 2009 – 5:35 pm
Firefox 3.0.7 is available for Solaris according to BlogFinger.
Does anyone remember Internet Explorer and Outlook Express on Solaris Sparc around 1998 or so? It was neat running IE on a Sparc workstation and OE was great for reading USENET. It’s too bad Microsoft discontinued support for it. Fortunately, we now have a great browser called [...]
Linux.com domain sold
March 5, 2009 – 5:25 pm
Computer world reports that the domain Linux.com has been sold by SourceForge to the Linux Foundation. The Linux Foundation has posted a press release with their intentions.
I’m still kicking myself for not going domain-registering-overboard back in the early 90’s registering all the big company domains before the big companies did.
Back in those days you could [...]
One-Third of Dell Netbooks running Linux
February 24, 2009 – 12:10 pm
Laptop Magazine reports that one third of Dell’s Inspiron Mini 9s that have been sold are running Linux. I’m still up in the air about what netbook I’m going to go with — but it will definitely be running Linux/UNIX.
I’d really like to see a Dell Latitude line of netbooks. Inspiron, to me, just screams [...]
