Question

You have created an instance but can’t access this instance with ping, identify the steps, tools, and commands that you will use to troubleshoot the reported problem.

Answer 1

1. Try to do telnet id you use the port to connect
2. TRACERT Command is used to identify where the instance is not able to contact.

The TRACERT diagnostic utility determines the route to a destination by sending Internet Control Message Protocol (ICMP) echo packets to the destination. In these packets, TRACERT uses varying IP Time-To-Live (TTL) values. Because each router along the path is required to decrement the packet's TTL by at least 1 before forwarding the packet, the TTL is effectively a hop counter. When the TTL on a packet reaches zero (0), the router sends an ICMP "Time Exceeded" message back to the source computer.

3.Tool:-(To trace the network where the network issue is there)

Wireshark is distributed as a free open source packet analyzer. The utility provides a detailed report on the traffic flowing through your Network Interface Card (NIC), and may be used in benchmarking network performance and troubleshooting network issues.

First Steps

If you haven’t done so already, the first thing you’ll need to do is install Wireshark on your testing system. The setup program can be obtained from the Download section of the Wireshark website.Wireshark is designed to capture and log the activity on your network in real time, so that you can sort through and analyze the results in your own time.You should use port mirroring, if you wish to examine traffic on an Ethernet port other than the one your Wireshark system is plugged into.

Capturing Interfaces:-

Once you’re clear on what you hope to achieve with the software, you can begin capturing network traffic by choosing Capture, then Options. The Options menu enables you to specify the length of time that Wireshark should run for, or the amount of data it should capture before it stops.Select the interface you want, then click Start. Once you’ve clicked Start, you’ll see network traffic movements in real time – and be able to stop Wireshark from running manually, if you haven’t configured an automatic stop.Wireshark produces a log, in which each individual line represents one packet that was exchanged. Individual packets may be selected to get a drill down and deeper analysis of its contents

Memory Allowance

It’s important to realize that Wireshark captures its information to memory, which may cause the program to hang if it’s run for a considerable length of time, or when overall system memory is low. Wireshark’s own documentation specifies that capturing interfaces on a fully saturated 100 Mbit/s Ethernet will produce around 750 MB of data per minute – a rule of thumb worth remembering in relation to your own system’s specifications and available resources.
