If you are installing ta-lib for Python and get this error then you can normally solve it by manually getting the ta-lib source files and compiling.
tar -zxvf ta-lib-0.4.0-src.tar.gz
cd ta-lib;./configure;make;make install
Collecting ta-lib

How To Install Wazuh Server / Quickest Installation
Wazuh (forked from the well known OSSEC project) is a full SIEM (Security Information Event Management) that works extremely well with the platforms it natively supports as an "Agent", which allows you to do scans of everything such as all processes running, CVE vulnerability check, incident reporting etc...
Prerequisites:
A lot of issues with Wazuh seem to be caused by i........

This is only really necessary in the case you don't want DHCP. If you are dealing with an encrypted LUKS server on the internet, you will often want to have a static IP so you know which IP to connect to (or if you have a semi-static IP assigned by DHCP).
SET IP Address by /etc/initramfs-tools/initramfs.conf
IP Address=192.168.1.27
Gateway=192.168.1.1
Subnet Mask: 255.255.255.0
Hostname=myhome.com
IP=192.1........
In this case I am executing using "python3" but what you find in cases like this can be surprising.
The most common issues are that someone has a module for python 2 "pip" and doesn't realize they need "pip3" to install it for python3, but this is not one of those cases.
ModuleNotFoundError: No module named 'bs4'
OKmaybe we didn't install it for python3?

I do not understand why heartbeat would try to communicate with another system not considered part of the node:
heartbeat: [8280]: WARN: string2msg_ll: node [otherbox.com] failed authentication

ResourceManager[31705]: CRIT: Resource STOP failure. Reboot required!
This happened on a cluster Iam running with heartbeat for no particular reason that I can figure out.
The box ended up rebooting itself for some reason. It was not a big deal in the sense that the other servers in the cluster kept running but it would be nice to find the cause of this.........
It really seems that 4.4.4 is not ready or stable for the i717 yet and this makes sense since it takes a lot of work/development and testing to get the factory stock ROMs working well. In the end I used the 4.1.2 based Blackstra BlackJelly because it was fast, stable and just works and feels great. The aftermarket support is great but many devs are focussed on adding features and customization that most of us don't want or need rather than getting things smooth and stable.........

Iused the slightly older "304.117" version and it worked.
With the newest version Icouldn't get X to start and kept getting these errors in messages/dmesg.

I dread updating the kernel and rebooting to find the Ubuntu graphics aren't working and you have to manually intervene. This is usually because Ubuntu for whatever reason didn't update the drivers you need (eg. the manually compiled Nvidia Kernel driver that MUST be recompiled for each and every kernel update unfortunately).
The most common reason may be that "linux-source" hasn't been installed automatically on my system. I tried to manually reinstall the........
I've only used it on Centos, soI thought I'd make a quick Debian guide:
Install the DRBD Package

Building dependency tree
Reading state information... Done
The following packages were automatically installed and are no longer required:
libswfdec-0.8-0
Use 'apt-get autoremove' to remove them.

heartbeat is stopped for some reason
Anyway hnode2 was active and the services are running fine but I see heartbeat has been stopped somehow.

A VPS Server I had just wasn't working right, code that I migrated there just wasn't working. For example, it kept telling me the connection to the database was unsuccessful, halfway through iterating through results it already had.
Then I realized it wasn't my code. Ichecked my /proc/user_beancounters and found this:

There's a lot of information and guides on OCFS2 for RHELand Centos Linux but the package setup and configuration is slightly different and this has thrown some people off.
Installing OC2FS
You should install the following packages to get started:
apt-get install ocfs2-tools ocfs2console
Configure OC2FS
In RHEL/Centos the main configuration file is located in /etc/sysconfig/o2cb
However in Debian based Linux it is located........
