Best tool to find packet loose

[marchen]

Hi,

What is the best tool to find packet look in server level? Is there any standard tool out there?

Packet sniffer is a program which monitors network traffic which passes through your computer.A packet sniffer which runs on your PC connected to the internet using a modem,can tellyou your current IP address as well as the IP addresses of the web servers whose sites you are visting.

That doesn't really help though john as it's a little bit overkill

First place I would start is with ping

I'm not sure about what you exactly require from your question but, if you are talking about a software to monitor packets being sent over the network, I would highly recommend wireshack.

I've been using it as a network troubleshooting tool for a while now.

Schumie, ping is only for testing whether a device is up or down. I don't think that is what the poster is looking for.

So your answer does not help either.

And how does it do that? By traversing the network

As the per the thread subject "Best tool to find packet loose" (I'm guessing "loose" was meant to be "loss" )

In the very initial, their is no need to use wireshark, tcpdump, etc.. you first need to identify where your loss is happening! Ping and traceroute (MTR is a good combination!) if going to provide you an invaluable resource in starting to narrow down where you think the loss is happening.

That's not necessarly true. Ping reports the roundtrip time to a device and also reports whether or not there was actual packet loss.

I us to use MTR. It's very useful and produces an advanced traceroute.

You can download a windows version here WinMTR - 0.8

for CentOS
#yum install mtr

I guess thats right.

If the poster meant packet loss... then you are absolutely right. Traceroute and ping will help in finding out where the packets are being lost

That is very true. I have gone back to re-read the original question and I must admit that I misunderstood the question when I first replied to it.

Sorry about that.
