Taming the Terminal – Bart Busschots: Recent Episodes
None
In the previous instalment we learned how to use the tmux as a replacement for the screen command which has been deprecated on RedHat Enterprise Linux (and hence CentOS too). In this instalment we’ll take TMUX to the next level, making use of the fact that a single TMUX session can contain arbitrarily many windows, […]
Since we covered the screen command in instalment 36, it has been deprecated in Red Enterprise Linux 8, and the official advice from Red Hat is to transition to the tmux command. Having been a fan of screen for years, I was skeptical, but I shouldn't have been — tmux can do everything screen can, […]
Since we covered SSH in parts 29 & 30, Apple have changed how their desktop OS deals with the passphrases protecting SSH identities (key pairs). This provides us a good opportunity to have a look at the SSH Agent in general, and, how things have changed on the Mac in particular. The good news is […]
The previous 13 instalments in this series related to networking, but we’re going to change tack completely for this instalment, and look at two un-reltaed, but very useful terminal commands – screen, and cron. screen is a utility that allows for the creation of persistent virtual terminal sessions that you can disconnect from without terminating, […]
The previous instalment we introduced the HTTP protocol. In this instalment we’ll look at three terminal commands which make use of the HTTP protocol. We’ll start by browsing from the terminal, and then move on to a pair of very similar commands for making HTTP requests from the terminal. These two commands can do many […]
In the previous instalment we finished a five-part series on SSH. Before moving on, lets take a moment to step back and look at the big-picture. The five SSH instalments are all part of the now long-running series on networking. We have been working our way through the networking stack since instalment 23. We started […]
This is the final SSH instalment. So far we’ve learned how to securely execute terminal commands on remote computers, how to securely copy files across the network using SSH, how to add both security and convenience to both those operations with SSH key pairs, and how to tunnel just about anything through SSH. In this […]
This is the fourth SSH instalment. So far we’ve learned how to securely execute terminal commands on remote computers, how to securely copy files across the network using SSH, and how to add both security and convenience to both those operations with SSH key pairs. As we saw in the previous instalment, SSH’s ability to […]
In Part 29 of n we learned how to use SSH to execute commands on a remote computer. In the previous instalment we learned how to add security and convenience to SSH connections using SSH key-pairs. The most important thing SSH provides is an encrypted connection between two computers. As we’ve seen, that encrypted connection […]
In the previous instalment we saw how we can use SSH to execute a single command on a remote computer, or, to get a command shell on a remote computer. We also saw how SSH uses host keys to protect us from man-in-the-middle (MITM) attacks. In this instalment we’re going to look at how we […]
