Life update..!!!
Been away for a while, been a lot going on…
Graduated yesterday, 10th November, 2026. 🎓🎉
Thank God for this milestone, now time to fully lock in with Cybersecurity.

4 years don truly waka 🎉🎓🙌🏽

Solved DOM XSS in jquery selector using a hashchange event on PortSwigger Web Security Academy 👾 👾
Used an iframe with an onload event to trigger a hash change, injecting <img src=x onerror=print()> into the vulnerable jQuery selector sink.

Syslog and SNMP with @JeremysITLab....Bro is the king of networking 🫡 🔥

@PHEDconnect been messing up my CCNA journey lately 😤

lab to check how STP(Spanning tree protocol) works.

Network Engineer Question

A fibre link shows optical power within the acceptable range, but interface errors and packet loss keep increasing.

What should you investigate first?

A. Duplex mismatch or faulty interface
B. DNS configuration
C. DHCP lease time
D. OSPF router ID

[Tremaine McAdams @TreyInTech]

🚀 My roadmap for breaking into Cloud Engineering:

1️⃣ Networking 🌐
Master TCP/IP, VLANs, routing, switching, DNS, DHCP, and OSPF. (CCNA)

2️⃣ Linux 🐧
Build a strong foundation in Linux administration, Bash, permissions, services, and system management. (RHCSA)

3️⃣ Automation & IaC ⚙️
Learn Python, PowerShell, Git, Ansible, Terraform, and infrastructure automation.

4️⃣ Cloud ☁️
Take those skills into AWS or Azure. Learn cloud networking, compute, storage, IAM, and infrastructure deployment.

The goal? Build a strong foundation before specializing.

One step at a time. One lab at a time. Always learning.

What’s your roadmap? 👇

[Segun @sudosheggs]

Completed the OWASP API Security Top 10.
Explored the 10 critical API security risks, including BOLA, Broken Authentication, BFLA, SSRF, and Security Misconfiguration.

This is honestly really cool.

Network Engineer Question

A network experiences intermittent connectivity. Switch logs show frequent STP topology changes.

What is the most likely cause?

A. Unstable switch links or Layer 2 loops
B. Incorrect DNS configuration
C. DHCP pool exhaustion
D. High OSPF cost

[𝐇𝐚𝐦𝐳𝐚 | Networking Guy @Hamzaonchain]

When a network engineer falls in love you get the heart topology

Network Engineer Question

A switch port is configured as an access port in VLAN 10, but the connected PC receives an IP address from VLAN 20's DHCP pool.

What should you investigate?

A. DHCP snooping
B. Incorrect VLAN or port configuration
C. OSPF area configuration
D. NAT

@Nik1910599 @wildfl0w6r @IgbojionuL31968 @CiscoNetAcad Nah.... Jeremy usually posts a free question at the end of each topic in his CCNA series

[Eddy @Devnet_____E]

Wrapped up QoS!

QoS Algorithms
QoS Models
QoS Implementations (IPP, DSCP & CoS)

All locked in for the CCNA 😂 (I wish).

Now it's time to lab my eyes out until it all feels natural 🧪

Lab 1 Troubleshooting
Pinged the directed broadcast address (10.1.1.255). All nodes reply, PC0’s ARP table fills up with IP-to-MAC pairs. Used "arp-a" to get the IP of the target host .
Small trick, very real troubleshooting skill.
What's your take on this @Wittynetworks😀
#ccna

[Eddy @Devnet_____E]

@Wittynetworks I really had no idea for that part 😂
I felt the bigger work was discovering the endpoint 💡🤧

[Eddy @Devnet_____E]

@amyy_nwa @wildfl0w6r @IgbojionuL31968 Oh sorry
I used some walk arounds to get the images
Could I send a msg , try to to sort it out

[Eddy @Devnet_____E]

Day 1 of GNS3
✅ 2 routers using real IOS
✅ OSPF adjacency over a serial link
✅ DHCP server on R1
❌ DHCP ACK to the PC wouldn’t just land, opened Wireshark to hunt it down
Packet Tracer would’ve just worked. GNS3 made me sad. worth it ? 😭
