TCPTRACE / TCP Troubleshooting

Hi all !!

Today I am going to show you how to trace TCP packet for our destination.

Often we see that we are allowed to browse the site only, and we are not able to trace the destination.

In this scenario, we always stuck to check the destination path.

first, we have to understand the communication process, Often we see the TCP segment flow the source and destination IP, Source IP having random port and destination IP having the well-known port.

Let's start the Technique to troubleshoot the TCP Communication.

1> We have to install WinPcap
2> tracetcp.exe to the current working directory of the cmd.

like: I have installed in C:\Users\Naresh>tracetcp.exe

I have given the link where we can download the necessary tools.

Now you can run the command like this:

I think the above information would be very useful.
Thanks for Reading.

Happy Learning !!!

Aruba 2930F / 2530 / 2540 Switch NTP CONFIGURATION

ArubaOS-Switch 16.05 NTP issue Often we found, the ArubaOS having issues with NTP time syncing. I have found the solution to tackle this issue. timesync sntp sntp unicast sntp 30 sntp server priority 1 SERVER X.X.X.X (NTP SERVER IP) time timezone 330 ( 330 for IST) Happy Learning :) Thanks, Naresh Mahato.

ArubaOS-CX, ArubaOS- Switch, Comware and Cisco IOS

The command line comparison demonstrated for 4 different OS of the switches, I think this will help you to understand the configuration level deployment. Comware Differences If you are familiar with either the ArubaOS-Switch CLI or the Cisco IOS CLI, you will notice that the Comware CLI is organized slightly differently . Comware was designed for Internet service providers (ISPs). Many features and functions—such as security and Quality of Service (QoS)—are multi-tiered to support the different needs of multiple entities accessing the same switch. ArubaOS-CX ArubaOS switch (now the Aruba OS), HPE Comware version 7 Cisco IOS ArubaOS-CX operating system runs on the 8400 and 8320 switches. ArubaOS Switch operating system runs on Aruba 2530 , Aruba 2920 , Aruba 2930F , Aruba 2930M , Aruba 3810M , Aruba 5400R , HPE 2620 , HPE 3500 , HPE 5400 and HPE 3800 switch platforms. HPE Comware7 operating system runs on HPE FF 12900 , HPE 12500 , HPE 5120/5...
