XenServer - capture network trace

[Bit-101]

XenServer - how to capture network trace to use with another utility to read.

I´m not familiar med XenSever commands or Linux.

I refer to this citrix article

https://support.citrix.com/article/CTX120869:

"Run the following command from the command line interface to capture an unfiltered network trace on the required VIF and write it to a file:
tcpdump -i vif<dom-id>.<device> -w /<path to file>
Following is a sample of the preceding command:
tcpdump -i vif16.0 -w /xenviftrace

 

I´m wondering about this:

<device> -w /<path to file>

 

Just want to write to a destination where I then can import the file into some utility to read the captured network trace.

I really appreciate some example of device name and a real example of path to file.txt or something.

(not just <device> and <path to file>)

 

:)

A device would be something like ie0; use "ifconfig" or better,"xe pif-list"to list network devices. A place to dump file might be in the temporary file are, onto which you would name also a file name, for example: /tmp/mydumpfile

Here's a good description of the process: https://support.citrix.com/article/CTX120869

You need a / before tmp: /tmp

Been a while since I've done that, but yes, you can use tcpdump to dump network traffic to a 

file and open it up with WireShark.

Thanks but when I´m trying to list all the directory under /root i recieve this:

 

Then I try ls tmp to get into tmp directory then i recieve this message:
"No such file or directory"

Obsolete

Are you running an 8x. version ? Very odd they would remove tcpdump, but stranger

things have happened.

In this case - XenServer 6.2

https://support.citrix.com/article/CTX120869#Capturing a Network Trace of a XenServer VM VIF

From root in XenServer:
xe vm-list name-label=server-01 params=dom-id
Output: "dom-id (RO) :8"
xe vm-list name-label=server-01  params=dom-id

xe vif-list vm-name-label=server-01 params=device
Output: Device: (RO) :0

Even tested:

tcpdump -i vif8.0 -s 0 -w /var/Reboot/xenviftrace

(Should I create the a file within Xenviftrace before I run the command, what format??)

 

I received the following error i XenServer conole:

 

 

Note:
The current server has an ip address and i can ping it from another server
