My personal workstation desktop can get a little cluttered. Regardless, I had open centos.org. I'm not sure when that happened, but I must have come across itsomehow and just saved it to look into later. Well later finally occured and I did some checking. I guess centOS isn't dead and I found this nice description of the ecosystem: --- Fedora is RedHat's play area. All new, crazy ideas are tested on Fedora before deciding if they are going to be added to RHEL or not. This is the reason why Fedora has a short and dynamic lifecycle, with every new release there is something novel coming up. CentOS is a stripped down, community supported version of RHEL. You can say that Fedora is (almost) a superset of RHEL, which in turn is a superset of CentOS. --- I know we used to have some centOS fans on the list and this info claified some things for me, so I decided to post it. I have a new, well used, system coming in a few days. I'm thinking that perhaps centOS may suit my needs and personality better. I'm considering installing it.

Security and Updates

by Gary

Today I received, via email, a security warning from my ISP, who is ATT. They were advising me that my system was being attacked and that the attack was based on an OpenSSH vulnerability. After reading some CVE and Red Hat pages, it turns out I'm at risk because I updated my bastion server. My other systems, which the bastion server front ends for, aren't affected because the version of OpenSSH is too OLD. What a pain. This happens all the time, whether I get notified or not. Newer versions of software are NOT more secure. In fact, they become LESS secure as developers try to incorporate more functionalty and edge uses. And, in this case, because someone made a mistake. The whole world is on this upgrade/update treadmill and it gets you nothing. IMHO you are delusional if you think it does. I have to get on it because I HAVE to upgrade browsers. You can only do this independently from an OS upgrade for so long. Fortunately the exploit is very difficut to exploit beyond causing a "system crash". It takes a lot of "resources" and thousands of attempts. Which is probably how ATT noticed it. I can't determine if, or ask ATT, to just block the attack. I can't respond to the email. It seems like blocking the attack would be nice. Fortunately, my network is on the slow side and the exploit probably can't be feasibly involked. This is why I resist upgrading/updating. It is a waste of A LOT OF TIME. Better to have a version and just patch vulnerabilities that apply to you and forget the rest. The recommended fix is to set the logingracetime=0 for the sshd server. I'm trying to determine how this will affect password based authentication with long passwords over slow/bad networks, my situation. It seems like it might. I'm seriously considering just downreving the OS on the bastion server. It doesn't really need that much functionality and never runs a browser. And, although I wouldn't like it, I'm not sure what they could do by executing arbitrary code there. They would have to be able to ssh somewhere useful. I can see from the logs that I'm being hit every 3 sec or so. All different IP's, must be a botnet.

user field libre office (windows vs linux)

by Brian E. Lavender

Can someone check a user field in libre office and check if they see a difference between the way it looks in the Writer doc in Windows vs Linux? Ctrl-F2 Variables User variable Name: fizz Value: [fizz] In Windows, it shows "User field fizz=[Fizz]" In Linux, it shows "[fizz]" Can someone check for me and let me know?

Poking Fedora 41 gently with a stick, are odd versions still bad juju? Feeling like I should wait for 42.
