Webinar: Automate IBM Connections Installations and morepanagenda
IBM Connections pink is based on Conductor for Containers, which provides a collection of tools to work with Docker containers and Kubernetes. To manage containers in large environments, lots of DevOps are using Ansible (an agentless software to automate administration tasks).
So why not use these tools to prepare your Connections operating system, like creating users, adding security settings or install all necessary packages to deploy DB2, Installation Manager, and WebSphere Application Server? Or use one of the available roles or tasks to automate even the installation of WebSphere, create cell and profiles …
In this session, you get the basics of Ansible and some hands-on to start the learning journey into ‘cloud’ based software management.

Installation And Configuration Of DNS, Web And FTP Servers On Virtual Machine...JohnWilson47710
The first Virtual Machine should be installed and have the BIND (DNS) server installed on it. While you do not own any address space/ name space your name server should manage the following domains:
The name server should answer queries for this domain. In addition to the saffioti.org.au zone, a zone should be set up for the reverse zone – the reverse zone would be whatever the address range is of your virtual machine. You should do some research on how Bind handles reverse zones.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

How to configure Nagios in Fedora ?
1. DATACENTER MANAGEMENT NAGIOS CONFIGURATION
Submitted By
Pankaj U. Rane (120851923024)
P.Venkatesh(120851923027)
Install and configure Nagios on Fedora Core 8 (VM or Physical Machine)
Monitor the following:
>> Local Machine
>> Remote Linux Machine (preferably Fedora) – Hostname to be displayed as “LINUX1”
>> Remote Windows Machine – Hostname to be displayed as “WIN1”
>> Remote Website – Name to be displayed as “MYWEBSITE”
*** MONITORING THE WINDOWS MACHINE***
To achieve this , we need to install an agent on the WINDOWS Machine.
Agent acts as a proxy between the Nagios Plugin that does the monitoring and the
actual service or attribute of the windows machine.
Client used for this user manual is NSClient++
The check_nt plugin will be used to communicate with the NSClient++
Steps involved:
Perform first-time pre-requisite.
Install monitoring agent on the Windows Machine.
Create new host and service definitions for monitoring the Windows Machine.
Restart the Nagios daemon.
Download the NSClient++ installer package from www.nsclient.org to the target
machine you wish to install it on.
Run the NSClient++ MSI installer package to initiate the installation. The welcome
screen will appear. Click Next to continue to the next step.
Read through the End User License Agreement.
Once you have agreed to itsterms, check the acceptance box and click Next to
continue.
You may customize the installation options on the next screen if you wish. No
changes are required for an working installation of the agent. Click Next to continue.
2. If an existing NSClient++ installation exists on the target machine, you will have the
option of using the old configuration file. This option is not enable if this is the first
time you are installing the client. Click Next to continue.
In the next step you will need to configure the NSClient++ agent. These steps
are important! Make sure you: Enter the IP address of the Nagios XI or Nagios
Core server in the Allowed hosts box.
Enter a password in the NSClient password box that will be required for
communication between the Nagios server and the Windows machine.
Check the following boxes in the Modules to load section:
Enable common check plugins Enable , nsclient server (check_nt) , NRPE server
and WMI checks. Click Next to continue.
Click the Install button on the next screen to begin the installation.
When the installation completes, make sure to check the Start service option and click
Finish to complete the setup.
The NSClient++ agent will now be running as a service, which means the Windows
machine is ready to be monitored with Nagios.
And now to Start->Run->cmd->services.msc and click on NSClient++ and select
the Logon tab and enable “Allow service to interact with desktop” and click “OK”
and Restart the NSClient++ service.
NOW CONFIGURE FEDORA TO MONITOR WINDOWS
