May we have the courage, strength & discipline to change situations we can, accept those situations we cannot change and the wisdom, knowledge and understanding to discern of the situations we find ourselves in.

Just started learning about ospf and tried doing a mini wan connection between lans , tho couldn't get it as good and detailed as online examples seen.
The .pkt lab is here for reviewing.

I saw a lab, 3 devices connected through a switch, 2 of them can ping each other, but only 1 cant ping the other 2.
Firstly checked if the port of the switch was on "no shutdown", then immediately checken the vlan and lo and behold, that was the problem.

Caught several phishing campaigns yesterday and ended up staying up till 5am triaging and analyzing detections.
By the end of it, I’d sent 27 reports to hosting providers, registrars, Google, and the affected brands.
Some of what I found:
- An internet banking clone harvesting account numbers and passwords. I was the first to detect it and scan it publicly.
- Multiple “free data/win rewards” scams tied to the same brand, with one collecting victims’ banking details. One hid its page behind scrambled code, which I decoded and sent to the host after they initially couldn’t identify anything malicious.
-Two fake banking/investment sites, among others.
Most reports have been acknowledged, and two sites have already been suspended.
It was a nerve-wracking night, but seeing the reports turn into action made every minute worth it. : )
Update on this 👇
Since then it's caught and reported real phishing:
• a scam campaign imitating a Nigerian brand: taken down by the registry ~18h after my report
• a fake bank page that captured victims' faces: found and scanned before anyone else had, offline within 5h of reporting
• a bank sign-in clone: reported 3 days ago, still up. Waiting on the host
Detection is half the job. Getting pages down is the other half.
I'm genuinely excited about this one, and I can't wait to share what I've built in due time 🫶🏽

Worked on a lab for inter vlan connectivity with multi-layer switches.

This took less time to set up than the day I was learning about trunking directly with router using ROAS.
The main reason why this is a better option is, the routers that originally handle all trunking across vlans also handle other complex network actions.

The major thing i learnt is that interfaces connected to end hosts are usually access ports, they do not need trunking, i made that mistake the first time and throughout yesterday, i spent time trying to debug why my ping wasn't working
