Unable to access the PaloAlto VM image via HTTPS

-

Recently, I encountered an Issue of "Unable to access the PaloAlto VM image via HTTPS". Here's how I applied troubleshooting steps to resolve it:

Configuration Changes done before: Configured static management IP & default gateway and rebooted the PA VM, then faced the issue.

Observed: Unable to access the PaloAlto VM image via HTTPS. Unable to ping to the default Gateway from the PA and viceversa. Error- getting Destination Host Unreachable in both cases.

Analyzed:
+ Checked the Management IP address and netmask, both are same as bridged network (physical)
+ Checked the default route "show routing route" - no route configured
+ While pinging from the base machine to PA and vice versa getting error as "Destination is Unreachable".

Hypothesized:
+ As per the Error message, primarily issue is Network related, that the PA VM is unable to reach physical NIC IP.

Tested:
+ Tried with changing the management IP address within the same subnet (as physical NIC subnet range) still had the same issue.
+ In order to find out which virtual network (I had few more virtual networks configured) attached to the VM, configured the mgmt interfaces dhcp client from CLI using below commands.
>> configure
>> set deviceconfig system type dhcp-client accept-dhcp-domain no accept-dhcp-hostname no send-client-id yes send-hostname yes

+ after enabling the dhcp on the mgmt interface found out, another virtual Network automatically assigned to the VM.

Resolved:
+ I switched the settings to the physical NIC and changed mgmet IP and gateway statically, issue resolved.
+ If you're using custom bridge network in VMWare Workstation, change the "Bridged To" setting from Automatic to the Physical NIC card
+ If you're using default bridge network from the VMWare, don't forget to select Replicate Physical Network Connection.

Grasped: How to Troubleshoot if the PaloAlto is up in CLI and unable to access it via HTTPS and Ping eventhough required preconfiguration applied.

Understanding Titanic Survival Predictions with Decision Trees

-
Image
  Decision Tree: Supervised learning Algorithm Can do both Regression and Classification capabilities Inverted tree like structure with bunch of if-else statements The Titanic dataset is one of the most famous case studies in data science. It captures passenger details such as age, sex, class, fare, and family aboard, along with whether they survived or not. In this post, we’ll walk through how a decision tree model uses these features to predict survival, and what the visualization reveals. How the Decision Tree Works Note: These features are based on the importance table at the right side Root node: “Was the passenger male?” If female , survival chances are much higher. The tree then considers passenger class and fare to refine predictions. If male , survival chances drop significantly, but age and family aboard (siblings/spouses) still play a role. Each node in the tree shows: Gini impurity: How mixed the group is (lower / purer). Samples: Number of passengers in that group. ...

From Raw Logistics Data to Business Insights: An Excel Analytics Project (RFM Analysis)

Analyzed logistics shipment data in Excel to evaluate delivery performance, cost, transit time, distance trends. Extended the analysis with RFM-based carrier segmentation to understand carrier utilization and spending patterns, supporting more data-driven operational decisions. My objective was to explore two practical business questions: How are delivery delays and shipment outcomes behaving across time and distance? How can carrier performance be evaluated using cost, transit time, shipment activity, and delivery performance? Starting with data quality I first reviewed the dataset for completeness and consistency. The initial cleaning process included identifying missing delivery dates and transportation costs, checking transit-day inconsistencies, and investigating numerical outliers. One thing I wanted to avoid was treating every unusual value as bad data. After null-value treatment, the working dataset contained 1,928 shipment records , while the dataset used after the selected ...
