Hi all,
I'm trying the following scenario and PDUMP doesn't start up even though
I'm running traffic generator. My idea is to generate traffic from one host
and dump on another host.
1. Downloaded DPDK latest version on two hosts and compiled DPDK with
CONFIG_RTE_LIBRTE_PMD_PCAP=y
2. On both of these hosts, I made one of the NIC as DPDK enabled
3. On host 1, I did:
./app/app/x86_64-native-linuxapp-gcc/pktgen -c 0x1f -n 3 -- -P -m "[1:3].0"
The packet generator starts and prints:

It looks like, it is trying to start pdump in both server and client mode
and neither worked and hence exited. Any idea what could be wrong?
Thanks,

Hi,
The dpdk-pdump tool cannot be run as a standalone. The ``dpdk-pdump`` tool can only be used in conjunction with a primary
application which has the packet capture framework initialized already. This point is added in latest doc $dpdk/doc/guides/tools/pdump.rst.
In DPDK test-pmd is already modified to initialize packet capture framework.
So, you must run test-pmd first to do Rx/Tx of the packets and also to initialize Packet capture framework.
Once test-pmd started , in another window run dpdk-pdump tool, then you will be able to see the packets in pcap file.
If any questions do let me know.
Thanks,
Reshma
