I just read Leadership and self-deception : getting out of the box and I am sure I will have to read it a few more times to have it sink in, but I like what I got out of it so far. I like that it goes beyond “don’t be selfish” to talk about the ways that a mindset can color our perceptions of other people. It hit pretty close to home for me and I am glad to have found it.
It amazes me the amount of incorrect information that is put on user forums. There are always mistakes and I have seen some posts where people realize and correct their errors. Primarily though, I see people ranting about “the correct way” when that way is not based in product knowledge, but rather on “it seemed to work”.
This reminds me of the time I went to the pet store to buy some activated charcoal after my dog ate some wild mushrooms. The box I was given was regular charcoal, but the employee assured me that it was the same thing because she had used it and her dog did not die.
Just because “it seems to work” does not mean that what you did was correct.
For the past 10 years I have been doing system administration and have benefited greatly from search engines and forums, but I have not provided much content. I am trying to correct this by creating this blog and participating in online forums.
Time will tell if I can keep it up.
I needed a way to allow our admins responsible for patching to include VMware Tools updates during a patch cycle. You can easily update via Virtual Center, but this requires multiple interfaces and it can be difficult to pick all of the same servers without making a mistake. I fired up Process Explorer and watched what VMware did with their existing tools update process. This is pretty cool since it does not require a network connection and your Tools install is up to date without needing to maintain a repository.
“C:\Program Files\VMware\VMware Tools\VMwareToolsUpgrader.exe” -p “/s /v\”/qn /L*v C:\Windows\Temp\ToolsUpgrade.log\””
It is interesting to read about more formal approaches to system administrator education. I have been reading “Master Education Programmes in Network and System Administration” from the LISA 07 proceedings. The authors’ approach is an interesting one, but I wonder what we do for all of the administrators already “in the wild”? A training vs. education mentality and the difficulty of adult education make introduction of a program like this very difficult.
The program also seems to be self-selecting. How can we set the standard so these types of skills will become more mainstream instead of a small number capable of formal analysis? Are employers going to see the value in this becoming mainstream and be willing to pay for the advanced level system administrators?
I was looking into Cisco Discovery Protocol details and read that you can negotiate POE using CDP packets. Could a malicious trojan forge some CDP packets and energize the POE link to the PCs nic?
I am new to blogging, but I figured that creating an online persona is a good thing.
