If you send console output via email (like, say the output of jekyll build as part of a SVN post-commit hook script) if there are ANSI control characters in the string (e.g. colour codes) this can break things. In this case the mail command (Debian 9 default exim) was only sending text up to the first ANSI code, which meant that the jekyll build error messages (which are yellow and red) were missing.

The default terminal shell in macOS Catalina has changed from bash to zsh. Unfortunately it seems the Anaconda installer doesn’t know about this yet. To fix the install copy the section of code added by Anaconda from
~/.bash_profile
to
~/.zshrc
See this post for example.
When trying to query FlexNet licenses using lmutil or similar from systems with a different DNS suffix, make sure that the license file server name contains the FDQN for the SERVER line. If not you can find that lmutils complains that the lmgrd process is not running, even though you can run the actual program with the appropriate license.
For example, with a line in the licence file like
SERVER servername 4eca3b4b8326 1055

In the previous post on this subject we used code from Technische Universität Kaiserslautern to monitor our GPUs using OMD checkmk (now checkmk raw). With some new RTX2080s installed this broke, as the nvidia-smi check doesn’t report anything for ECC errors (rather than 0, as previous cards did). The solution was to remove the ECC checking completely.
The new scripts are:
On the client system in /usr/lib/check_mk_agent/local/ (or plugins/)
nvidia-smi
if which nvidia-smi >/dev/null; then
echo '<<<nvidia_smi>>>'
nvidia-smi -q -x > /tmp/.check_mk_nvidia_smi
cards=$(xml_grep --text_only 'nvidia_smi_log/attached_gpus' /tmp/.check_mk_nvidia_smi | tr -d ' ')
IFS=$'\n' names=($(xml_grep --text_only 'nvidia_smi_log/gpu/product_name' /tmp/.check_mk_nvidia_smi | tr -d ' '))
IFS=$'\n' fan_speed=($(xml_grep --text_only 'nvidia_smi_log/gpu/fan_speed' /tmp/.check_mk_nvidia_smi | tr -d ' '))
IFS=$'\n' gpu_utilization=($(xml_grep --text_only 'nvidia_smi_log/gpu/utilization/gpu_util' /tmp/.check_mk_nvidia_smi | tr -d ' '))
IFS=$'\n' mem_utilization=($(xml_grep --text_only 'nvidia_smi_log/gpu/utilization/memory_util' /tmp/.check_mk_nvidia_smi | tr -d ' '))
IFS=$'\n' temperature=($(xml_grep --text_only 'nvidia_smi_log/gpu/temperature/gpu_temp' /tmp/.check_mk_nvidia_smi | tr -d ' '))
IFS=$'\n' power_draw=($(xml_grep --text_only 'nvidia_smi_log/gpu/power_readings/power_draw' /tmp/.check_mk_nvidia_smi | tr -d ' '))
IFS=$'\n' power_limit=($(xml_grep --text_only 'nvidia_smi_log/gpu/power_readings/power_limit' /tmp/.check_mk_nvidia_smi | tr -d ' '))
for i in $(seq 1 $cards) ; do
index=$(($i - 1))
fan_speed[$index]=${fan_speed[$index]/\%/}
gpu_utilization[$index]=${gpu_utilization[$index]/\%/}
mem_utilization[$index]=${mem_utilization[$index]/\%/}
temperature[$index]=${temperature[$index]/C/}
power_draw[$index]=${power_draw[$index]/W/}
power_limit[$index]=${power_limit[$index]/W/}
echo "$index ${names[$index]} ${fan_speed[$index]} ${gpu_utilization[$index]} ${mem_utilization[$index]} ${temperature[$index]} ${power_draw[$index]} ${power_limit[$index]}"

Don’t forget to make it executable! You also need xml_grep installed.

Windows driver – IJ Network tool does allow you to input IP address eventually (Mac version does not). Conveniently our print server was on the same subnet as the printer, so it found it straight away. Driver can be installed on Server 2012 and shared, but cannot be shared as a LPD queue (as Canon don’t use a standard IP port).
Printer does function as an IPP printer, and LPD (if enabled).
