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 [WayBackDetermining 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:

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: [WayBackbash – 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: [WayBacklinux – 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=0
  • network.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 about:config in the addressbar
  • Confirm the
    This might void your warranty!
    by clicking
    I accept the risk!
  • Search for network.http.response.timeout
  • Double click it so the value changes from the default value 0 to the user set value 0

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&nbsp;/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:
