@scottalanmiller said in How to Install PHP 7.3 on Ubuntu 18.04:

I hate having to do this, but sometimes it has to be done. Here is how to get this middling PHP version onto this old version of Ubuntu.

sudo add-apt-repository ppa:ondrej/php sudo apt update

I'm not sure that is the proper way to do it.
ppa are personal repositories - meaning someone put it together.

I think Ubuntu has offical backports, just like Debian.
In that case it would be better to get a the "newer" php version from the backport repository instead.

UPDATE.
It looks like the ondrej/php repository is actually maintained by a Debian developer, Ondřej Surý. He is one of the package maintainers for the official debian and ubuntu php packages.

@scottalanmiller I have tried to connect via virtualbox before but after the windows and linux setups the screen would just turn black so i resorted to qemu and followed your discussion but now it wont connect on ubuntu

@Pete-S said in MariaDB Package Issues While Updating from CentOS 7 to CentOS 8:

But nobody in their right mind...

...uses LTS releases. So we have to accept we are working from a crippled situation anytime that this comes up. It means we are already dealing with politics over function. So knowing that, it should explain why we have to deal with what we have to deal with. Would have been super fast to do a fresh install.

But you'd not do a fresh install of CentOS 8 or Streams if it wasn't for politics. We'd be putting in Fedora, Ubuntu, or OpenSuse. So not getting to do a fresh install is just one artefact of many when doing what's best for the application platform isn't what drives decision making.

@Pete-S said in Run ls as another user?:

What's the easiest way to run ls as the apache user (which you can't login as)?

su -u apache ls

Did you mean sudo or su?

Because you can't do su apache . You get "This account is currently not available.".

I know the -u apache is needed to run a command as a user from su or sudo. I'm thinking the issue might be with the apache account being set to nologin in /etc/passwd. Just be sure to change the shell entry in passwd back when you finish up.

-u is the user for either, but sudo is a loginless command and su uses login. To use su like you are thinking, you also need -c to make it a single command. Both will work, but only sudo will work for a non-login user like this without the -c

@Pete-S said in Notification mail in linux?:

Or is email perhaps not a good way to get notifications when there is a problem?

Maybe email in this manner is old-skool and it would be better to use something else?
Like external log server, system monitoring (Zabbix) perhaps?

Yeah I would use SIEM. Then you'd create and manage your alerts from there. You could send to email, slack, etc.

You can use postfix for alerting as JB mentioned. I use postfix on the my personal servers because I don't manage enough to justify a SIEM.

I thought that SIEM was only used for security monitoring. What SIEMs for example are we talking about for this type of application?

@DustinB3403 said in Oracle Linux Installation and performance seems insanely bad:

@Obsolesce CentOS as a product is dead, the alternatives are RHEL or CentOS Stream.

CentOS Stream is a totally different thing. Not what people consider alternatives. It is an alternative in the same way that Ubuntu or Windows is.

The real alternatives that are drop in replacements that work exactly the same and cost the same are Oracle Linux, AlamLinux and Rocky Linux.

Thanks, guys. It's actually the most logical solution that the ssh client side decides what keyboard layout to use.

So maybe I was mistaken then or it was something else that was off. I'll give it try with some different settings to verify how it works.

@scottalanmiller said in New to Linux Administration: RHEL-Based or Debian-Based OS:

I agree, both is the obvious choice. But to truly answer the question, I'd focus on Ubuntu (not Debian) and then RHEL. Debian is great, but it is Ubuntu specifically that has the market.

Yes, almost the same is never the same as exactly the same.

@gotwf said in SAMIT: IBM Is Killing Off CentOS:

@scottalanmiller Yes. This I know. But this isn't bare metal but rather SmartOS hypervisor in a Triton datacenter. So I presume all is atop ZFS. I never delved deeper so honestly do not know.

Hopefully not, as ZFS isn't all that fast. But you need XFS touching WiredTiger... what's lower in the stack isn't what it is concerned with. You still control your own filesystem regardless of what the datacenter may or may not use elsewhere.

@Dashrender said in Best practice security updates linux servers?:

saying Well - Johnny is just better employee than you, so I choose to pay him more, that isn't going to make people happy, it will likely make them less happy...

You are looking at it from the employer's perspective. Of course it doesn't help the employer. It helps the employee when they can see what X work is worth. If employee 1 makes X for a job, and employee 2 wants to know their own value, they have something to go on. If you don't know what others are paid you have almost nothing to go on.

Remember on Spiceworks when loads of people would claim that $65K was the IT industry cap? Imagine if people (and companies) were able to repeat that without anyone speaking up! People would surmise that if $65K is the top for a CIO, that a system admin must cap out at $50K and a helpdesk tech at $9/hr!

But in the real world, we know that CIOs make well into the seven figure range, admins can get well into the multiple six figures. Even good help desk leads can hit six figures. If we didn't have others to compare against, it's easy to see people misunderstanding the scope of the industry by an order of magnitude.

@EddieJennings

Impressive work Eddie!

Thanks :)

Honestly the best thing in my opinion is put k3os on it and run the stuff in a single node Kubernetes cluster. You'll get experience with k8s and the applications use very little resources when deployed this way.

I use it in pfsense router. It works against script kiddies, bots/botnets, at least partially. It's just another layer of security. And like it was mentioned before, it reduces log noise, with almost no effort.
