Show SCSI / HBA modules in ESXi 6.5 with file and version information
Posted by jpluimers on 2019/05/02
A small script I made: Show SCSI / HBA modules in ESXi 6.5 with file and version information:
MODULES=`esxcfg-scsidevs --hbas | awk 'FNR > 0 {print $2}'`
for MODULE in $MODULES ; do
# echo "Probing $MODULE"
vmkload_mod --showinfo $MODULE | grep 'file: \|Version'
done
The script is based on ideas from [WayBack] Determining Network/Storage firmware and driver version in ESXi 4.x and later (1027206) | VMware KB
It works in at least ESXi 6.5 where it shows this on one of my systems:
input file: /usr/lib/vmware/vmkmod/lsi_msgpt3 Version: 12.00.02.00-11vmw.650.0.0.4564106 input file: /usr/lib/vmware/vmkmod/vmw_ahci Version: 1.0.0-39vmw.650.1.26.5969303 input file: /usr/lib/vmware/vmkmod/vmw_ahci Version: 1.0.0-39vmw.650.1.26.5969303 input file: /usr/lib/vmware/vmkmod/vmw_ahci Version: 1.0.0-39vmw.650.1.26.5969303 input file: /usr/lib/vmware/vmkmod/lsi_mr3 Version: 6.910.18.00-1vmw.650.0.0.4564106 input file: /usr/lib/vmware/vmkmod/megaraid_sas Version: Version 6.603.55.00.2vmw, Build: 4564106, Interface: 9.2 Built on: Oct 26 2016 input file: /usr/lib/vmware/vmkmod/vmkusb Version: 0.1-1vmw.650.1.26.5969303

bash – aliasing cd to pushd – is it a good idea? – Unix & Linux Stack Exchange
Posted by jpluimers on 2019/04/30
On my research list: [WayBack] bash – aliasing cd to pushd – is it a good idea? – Unix & Linux Stack Exchange
It has a nice discussion on complements to pushd/popd/cd/dirs including a very nice set of navd scripts that eases the navigation of the directory stack.
I found it because the ESXi busybox does not have pushd and popd and a cd won’t work from inside a shell script: [WayBack] linux – Why doesn’t “cd” work in a bash shell script? – Stack Overflow
It also made me find out that the ESXi busybox does support cd - to go to the previous directory. More info on that cd syntax is at [WayBack] bash – Difference between “cd -” and “cd ~-” – Unix & Linux Stack Exchange

Firefox 29 and up: “The connection has timed out”
Posted by jpluimers on 2019/04/24
A few years ago, Firefox changed the default “network.http.response.timeout” value from zero to 300 seconds (5 minutes).
Display style systems that show refreshing web pages, this can be a problem as when the connection to the web-server is unavailable for more than 5 minutes, then the page will show “The connection has timed out” and stop refreshing.
The solution – apart from fixing each and every connection problem – is to either restore the value or make it very long:
network.http.response.timeout=0network.http.response.timeout=30000
Changing this works similarly like in A way to skip the Firefox “Well, this is embarrassing” during a sudden reboot « The Wiert Corner – irregular stream of stuff:
- Open Firefox
- Type

This might void your warranty!

I accept the risk!- Search for

Lesson learned: do not copy/paste code from the `Visual` WordPress.com editor…
Posted by jpluimers on 2019/04/16
[WayBack] Lesson learned: do not copy/paste code from the Visual WordPress.com editor; copy from the Text editor or the Preview… – Jeroen Wiert Pluimers – Google+.
Note: likely the HTML below got rendered badly by WordPress.com, so the gist below has the same text as a MarkDown file.
Ever wonder why copy-pasting code from your WordPress.com post fails?
The first statement fails, but the second works:
[root@linux:/etc] # useradd --create-home --shell /bin/false autossh24
useradd: unrecognized option '--shell /bin/false'
...
[root@linux:/etc] # useradd --create-home --shell /bin/false autossh24
[root@linux:/etc] #
The reason is that the first is copied from the Visual WordPress.com editor that renders this HTML inserting which is a different unicode characer (0x00A0) than a normal space (0x0020):
<blockquote><p><code data-mce-selected="1"># <strong>useradd --create-home --shell /bin/false autossh24</strong></code></p></blockquote>
However, the the second copied from the Text WordPress.com editor succeeds because it has all regular spaces:
<blockquote><code># <strong>useradd --create-home --shell /bin/false autossh24</strong></code></blockquote>
Luckily the Preview render is correct:
<blockquote><p><code># <strong>useradd --create-home --shell /bin/false autossh24</strong></code></p></blockquote>
Lesson learned: do not copy/paste code from the Visual WordPress.com editor; copy from the Text editor or the Preview.

mail-filters/Makefile at master · fumiyas/mail-filters
Posted by jpluimers on 2019/04/15
Cool tool if you use Postfix: mail-filters/Makefile at master · fumiyas/mail-filters.
You set it up like this:
cd /etc/postfix
wget https://raw.githubusercontent.com/fumiyas/mail-filters/master/postfix/Makefile
Then each time you change your postfix configuration:
cd /etc/postfix
make
In that directory, it will (re)generate a Makefile.postmapbased on the lines with hash in main.cf, then make each .db file from the source hash file.
After that you have to manually restart postfix, which depends on your Linux flavour.
Similar solutions:
- [WayBack] Using “make” for Postfix file maintenance
- [WayBack] Postfix Makefiles – Web and dedicated hosting tutorials by Anchor
(also does a reload on one specific flavour) - [WayBack] HSC – Brève – Makefile for postfix configuration
(also does a reload on one specific flavour)

Some links and notes as I want to learn about JavaScript in bookmarklets
Posted by jpluimers on 2019/04/11
I wrote about bookmarklets before, but more from a usage perspective, not from a programmers one.
From what I understand now is that:
- bookmarklets are basically a special form of URI
- you can use JavaScript in them, but must make sure you do not interfere with existing JavaScript on the page
javascript:(function(){ window.open('https://wiert.me/'); })();
- the URI has limits so,
- browsers can have length restrictions (some around 500 characters) forcing you to put the actual script on-line as externalised bookmarklet (which won’t work on body-less pages)
- you will have to encode special characters (and URI decode them before beautifying existing JavaScript bookmarklets)
My first tries will likely be:

Python Data Science Handbook | Python Data Science Handbook
Posted by jpluimers on 2019/03/21
Cool stuff: [WayBack] Python Data Science Handbook | Python Data Science Handbook.
Based on that I learned a lot of things on book publishing:
- The book itself is on GitHub: jakevdp/PythonDataScienceHandbook: Jupyter Notebooks for the Python Data Science Handbook
- [WayBack] IPython (a command shell for interactive computing) has a spin-off Project Jupyter, a computational notebook interface [WayBack] that besides Python, also supports Julia, R, Haskell and Ruby.
It has:- a GitHub repository too: Carreau/jupyter-book
- a book on itself [WayBack] Jupyter · GitBook
- an interactive web-site to try the notebooks: [WayBack] Project Jupyter | Home
The Jupyter Notebook is a web-based interactive computing platform. The notebook combines live code, equations, narrative text, visualizations, interactive dashboards and other media.
