Using tcpdump on a Virtual Appliance

Authors list

When troubleshooting network related issues on a virtual appliance/linux machine, tcpdump is the linux equivalent of wireshark. 

To install tcpdump: 

Enter the following command in the terminal of the appliance to install tcpdump: 

yum install tcpdump

Confirm the installation with "y"

Use the following command to capture and save the packets in a file:

tcpdump  -vv -w  FILENAME.pcap -i any

Reproduce the issue, so it is captured in the tcpdump log. 

To cancel the capture press: 

Ctrl + c

To compress the output file: 

tar -cvzf FILENAME.tar.gz FILENAME.pcap

Please send the compressed output file: FILENAME.tar.gz to ESET Support.
