@gjacobse the article is a little misleading. Linux doesn't provide DNS services. So Linux can't be the issue. Any given Linux distro might have one or more default DNS server options, so Ubuntu or RHEL might have this issue, but Linux itself cannot.

In the article, you have to dig before they mention BIND, a DNS server, as being a problem with this issue. BIND is certainly the de facto standard on Linux and represents a problem for the community and ecosystem, but the article presents it in very much a click bait sort of way.

And then it appears to describe the issue as a protocol issue, not an implementation issue and seems to feel that the issue is just that the protocol used for DNS was insecure.

API and a script

@pete-s said in Shift + PgUp/PgDn in terminal?:

When you use Shift + PgUp/PgDn on a linux console you can scroll the screen buffer.

Where does this behavior come from? Is it the shell, a utility on the server, is it the console client, is it the ssh client?

It's not working for me using ssh (on windows) and I realized I have no clue where to start looking...

Probably specific to the config of your terminal program, unless you’re truly talking about the console itself.

I had to alter some key bindings in Gnome Terminal to get the desired behavior from the weechat key bindings.

You were right. I was trying out Windows Terminal and running ssh inside. And shift+pgup/dn didn't work as expected.

I looked at the Windows Terminal keybindings and the default was not what I wanted.

So I added this under "actions" in the settings.json file:

// Scrollback { "command": "scrollDown", "keys": "shift+down" }, { "command": "scrollDownPage", "keys": "shift+pgdn" }, { "command": "scrollUp", "keys": "shift+up" }, { "command": "scrollUpPage", "keys": "shift+pgup" },

The added bonus is that shift+pgup/dn now also works with cmd.exe and PowerShell.

@stuartjordan said in Managing Publicly hosted Linux Servers through Cockpit:

Cockpit looks nice and all that, but the version I tried didn't seem to have as many features or as much control like webmin does.

Tried Cockpit on Ubuntu? If so, you probably been using a old version because the only distro that I know that always has the latest version is Fedora.

Yep I'm a Debian/Ubuntu guy. I could probably add the repository for the latest version to try out if it does have more features. I'm normally straight up do everything through cli but wanted to try it out. then I tried webmin out which I haven't touched in over 8 years. They have defiantly improve things on their panel.

@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.

@travisdh1 said in Run ls as apache user?:

@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

@IRJ said in Notification mail in linux?:

@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.
