Toolbx is a tool for Linux, which allows the use of interactive command line environments for software development and troubleshooting the host operating system, without having to install software on the host. It is built on top of Podman and other standard container technologies from OCI.

Toolbx environments have seamless access to the user’s home directory, the Wayland and X11 sockets, networking (including Avahi), removable devices (like USB sticks), systemd journal, SSH agent, D-Bus, ulimits, /dev and the udev database, etc..

Awesome!

You can configure an alarm to run a script or a command in the vSphere Web Client when the alarm is triggered.

Use the alarm environment variables to define complex scripts and attach them to multiple alarms or inventory objects. For example, you can write a script that enters the following trouble ticket information into an external system when an alarm is triggered:

• Alarm name
• Object on which the alarm was triggered
• Event that triggered the alarm
• Alarm trigger values

When you write the script, include the following environment variables in the script:

• VMWARE_ALARM_NAME
• VMWARE_ALARM_TARGET_NAME
• VMWARE_ALARM_EVENTDESCRIPTION
• VMWARE_ALARM_ALARMVALUE

You can attach the script to any alarm on any object without changing the script.

The script runs on the vCenter Server machine, and it runs even if you close the vSphere Web Client.

There are lots of command lines which can be used with the Google Chrome browser. Some change behavior of features, others are for debugging or experimenting. This page lists the available switches including their conditions and descriptions. Last automated update occurred on 2020-08-12.

Click is a Python package for creating beautiful command line interfaces in a composable way with as little code as necessary. It's the "Command Line Interface Creation Kit". It's highly configurable but comes with sensible defaults out of the box.

It aims to make the process of writing command line tools quick and fun while also preventing any frustration caused by the inability to implement an intended CLI API.

Click in three points:

• Arbitrary nesting of commands
• Automatic help page generation
• Supports lazy loading of subcommands at runtime

Isn't it awesome how optparse and argparse generate help messages based on your code?!

Hell no! You know what's awesome? It's when the option parser is generated based on the beautiful help message that you write yourself! This way you don't need to write this stupid repeatable parser-code, and instead can write only the help message--the way you want it.

SSLyze is a Python tool that can analyze the SSL configuration of a server by connecting to it. It is designed to be fast and comprehensive, and should help organizations and testers identify misconfigurations affecting their SSL servers.

Key features include:

• Multi-processed and multi-threaded scanning (it's fast)
• SSL 2.0/3.0 and TLS 1.0/1.1/1.2 compatibility
• Performance testing: session resumption and TLS tickets support
• Security testing: weak cipher suites, insecure renegotiation, CRIME, Heartbleed and more
• Server certificate validation and revocation checking through OCSP stapling
• Support for StartTLS handshakes on SMTP, XMPP, LDAP, POP, IMAP, RDP and FTP
• Support for client certificates when scanning servers that perform mutual authentication
• XML output to further process the scan results
• And much more !

While you can use the database client to check the status of your cluster, the individual nodes and the health of replication, you may find it counterproductive to log into the client on each node to run these checks. Galera Cluster provides a notification script and interface for customization, allowing you to automate the monitoring process for your cluster.

How do I get exit status of process that's piped to another (for e.g. 'netstat -tulpn | grep nginx') on a Linux or Unix-like system using a bash shell?

In the fall of 2013, thinking about text utilities got me thinking in turn about how my writing habits depend on the Linux command line. This seems like a good hook for explaining some tools I use every day, so now I’m writing a short, haphazard book.

This isn’t a book about system administration, writing complex software, or becoming a wizard. I am not a wizard, and I don’t subscribe to the idea that wizardry is required to use these tools. In fact, I barely know what I’m doing most of the time. I still get some stuff done.

This is a work in progress. It probably gets some stuff wrong.
