Subject: pdump error : failed to send to (/var/run/dpdk/rte/mp_socket) due to Connection refused
Date: Fri, 1 Oct 2021 15:10:41 +0800	[thread overview]
Message-ID: <CANq=q42abKjHkY52_RPA2KpwDBhPMUFRm+iJ4y8jhK4c7zyTrQ@mail.gmail.com> (raw)

Dear,

I'm the new for using DPDK.
I met the problem while trying to use pdump to capture the packet from my
own application, but it bumps into some error as below. Do you have any
suggestions?

[oai@localhost pdump]$ sudo ./dpdk-pdump -- --pdump
'port=0,queue=*,tx-dev=/tmp/tx.pcap,rx-dev=/tmp/rx.pcap' EAL: Detected 72
lcore(s) EAL: Detected 2 NUMA nodes EAL: Multi-process socket

[./dpdk-pdump(main+0x52e) [0x480f1e]] 1: [./dpdk-pdump(__rte_panic+0xe0)
[0xe0f600]] Aborted

P.S.
The DPDK version in our lab is for 19.11.
After modifying CONFIG_RTE_LIBRTE_PMD_PCAP=y & CONFIG_RTE_LIBRTE_PDUMP=y,I
try to use ICC for the compilation.
Also, I already add function rte_pdump_init() in my application.

Best Regards,
Shu-hua, Liao
