How to perform a tcpdump on Redhat Linux

Steps to run a TCPDUMP on Redhat Linux


Red Hat Linux Enterprise and CentOS


It is suggested to utilize "Yum" to get this installed if it is not.

"yum install tcpdump"


Run this command:


tcpdump -i any -w /tmp/capture.pcap


This will log on ANY interface and on ALL ports.

This can be limited down, for example if you wanted only port 8080 traffic:


tcpdump -i any port 8080 -w /tmp/capture.pcap


However, for most issues relating to Broadcom products - ANY/ALL is helpful and we can filter the results down using Wireshark.
