With so many use cases and potential buyers, the vendors too often try to be everything to everyone. The result is a class of products that suffers from an identity crisis — so-called business storage solutions that are overloaded with consumer features and missing the ease and simplicity that business users require.

I found the below snippet to be interesting.
Connecting the NAS boxes to your network should be done via a wired Ethernet cable, and each NAS in this roundup should get two Gigabit Ethernet connections. Strictly speaking, you need only one of these links, but by using both, you gain much greater flexibility. You should use them in a fail-over configuration, which means that if one of your Ethernet cables loses signal, the other will take over. You should also “bond” the two connections together to increase throughput or to balance the network load.
Also.
NAS shoot-out: Everything else but the kitchen sink
All of the NAS boxes in this roundup have the flexibility to do more than merely store your data. These features are too numerous to review in detail, but they include such things as the ability to collect images from IP video surveillance cameras, mobile apps that allow you to access your data from iPhones, iPads, and Android devices, and multimedia servers that provide access to photos, music, and video.In addition to the built-in features, you can generally install software packages that extend the functionality. Typical add-on modules include BitTorrent downloaders, email servers, and content management and blog publishing applications.
SpinRite v6.0 achieves complete operating system independence by incorporating the FreeDOS operating system. This allows it to be used on any and all Intel/AMD PC systems. As you can see from the Windows screen image above, SpinRite 6.0 can create a bootable diskette or generate a standard, CD-R burnable ISO file to create a “SpinRite boot CD”. A bootable SpinRite can also be “installed” into any other motherboard bootable devices, such as USB flashdrives for easy, portable booting and use.

I wonder how this differs from just running Knoppix and mounting the “dead” hard drive.

Cherokee includes a web admin interface for configuring the server. To get that running you need to start it up on your server and then use SSH tunnelling to view in a local browser. So on your server run the following to start the Cherokee Admin deamon:
cherokee-admin -b &Then on your local machine, setup the SSH tunnel as follows:
ssh-L 9090:localhost:9090 mysite.com -NNow, navigate to http://localhost:9090 and log in using the username and password shown in the output on your server console. You should be greeted with the Cherokee Admin home screen!

Previously, Abhijeet has highlighted three awesome sites where you can create your own social network easily. However, if you are one of those who wants more control of the site, including the branding, the domain name, the features, the design, the community rule, or even the database, the best way is to install and run a social networking software on your server.
While there are plenty of scripts (both free and paid) that you can use to run your own social network, there are only a few that are stable, good and easy to use.
For SATA drives, occasional transmission problems are expected even on otherwise pretty healthy systems. No need to worry about it too much unless the problem repeats itself a lot.

This error occurred on the drive using the hot swap cage. I wonder if perhaps the circuitry on the cage is iffy. The circuit board on that cage is about the simplest board that can be designed — it just maps wires from one pin connector to another — that’s it.
Perhaps the centos install is OK after all. It’s intermittent which is bad. Looks like it might pay to use higher quality hot swap cages. Tomorrow I’ll try another brand and investigate this further. Here’s another pertinent point. I’m seeing this exact same error.

That’s your drive reporting that it saw transmission error on the wire.
if u are running shadowed passwords it might be theres no entry for this user. make a backup of /etc/shadow, delete /etc/shadow and convert /etc/passwd using pwconvert.same goes for /etc/groups.
via Authentication Token Manipulation Error.
I got this error when logging in as root into a system that I think was badly installed (by me). Anyway, this fixed that problem. I found it interesting that this came up #1 on the google search and it’s an entry dated May 2001.
Note: The linux command pwconv replaced pwconvert sometime during these last ten years.
Note2: Here’s a more modern (3 years old) explanation tmhat I found useful.
Note3: I still had to do a complete reinstall since a lot of things went haywire. I probably shouldn’t have been playing with hot swapping while the install was in progress.
Update:I don’t think the kernel likes this motherboard. Second install failed. Have to resort to compiling a kernel by hand. What started out as a simple hour long task will now take all night.

I got confused between two Centos VMs. I had thought one Centos VM that I have running DNS was Centos 5.4 and the new one was Centos 5.6. When I saw that they both used a 2.6.18.* kernel I got confused. Fedora Core is using 2.6.35 and greater. This led me to check the distro version upon which I didn’t get it out of uname -a or dmesg. Searching the intertubes and I got the above answer. Apparently the VM I thought was 5.4 is really 5.5.
It is interesting that Centos, which tracks RHEL, doesn’t make too many radical changes to the kernel.
Update: It should be noted that I wouldn’t have noticed the kernel versions had I not tried to compile and install my own kernel.
