rants and (hopefully) useful info
While we all know how to add tasks using crontab -e or check current tasks using crontab -l, doing things this way can sometimes be a bit inconvenient (eg. if you’re mid-script). Adding via CLI can be done in the CentOS implementation like this … echo “* * * * * \$HOME/path/to/scriptOrApp.sh” >> /var/spool/cron/USERNAME; ……
This is a LINUX version guide, based 99.99% on “Dr. Duh’s outstanding post on the topic”. I have read many such HowTo’s, and this one is, by far, the best I’ve seen (for my needs/preferences). The screens in his article contain the actual screens you’ll see when you run the commands needed. For me, that…
I am an absolute novice on the cyber security front, so I make no claim more than that about my ability. There are a lot of articles that claim/say “you don’t need an anti-virus system if you are running linux”. Maybe they’re right – maybe it’s just foolish optimism. Even so, much better to have…
There are a few cases where you might want to keep your old version of PHP for compatibility, or preference, but also need a newer or cutting edge version for a particular app (eg. Nextcloud [howto/whyto post to follow]). Fear not – this CAN be done. Here’s my marginally modified version of the post from…
Maybe I did it wrong, but the way my various LANs and systems are set up, I can’t always get to a few of my endpoints without a 2 step process of doing an SSH to 1 “server”, and then from there, doing a 2nd SSH to the desired endpoint. eg. If the remote endpoint…
Once you have set up your ssh keys on the remote host (the server), and also on the local client (your PC), you can connect without (necessarily) having to input a password. To make this secure, the 2 connecting machines need to establish that you’re an OK person on both sides by exchanging keys which…
There are MANY such guides on the internet – this one is probably not any different or better than those. You should read the man-page for SSH-keygen. THE best resource/book that I have read on the topic is SSH Mastery – Michael W Lucas. His books are generally some of the best on each topic…
Unless you think it would be wise to actually create a TXT file that lists all of your logins/usernames/passwords, and post it on a public forum or social media site like FB, you really SHOULD be using a password manager. For a brief moment (back then), I actually believed that the slight scramble on my…
There are literally hundreds of HOWTO’s on the net – each having good points and bad, each showing “better” ways to do things. They are incredibly useful…IF/ONCE you know what it is you’d like to achieve. What I have found though, is that by the time I know for sure what I want to achieve,…
