Hello, I want to use dpdk-pdump for packet capture. As explained in the http://doc.dpdk.org/guides/tools/pdump.html http://doc.dpdk.org/guides/prog_guide/pdump_lib.html I have compiled the DPDK with CONFIG_RTE_LIBRTE_PMD_PCAP=y and modified my application to initialize the pdump PMD by calling the rte_pdump_init()
I am invoking the dpdk-pdump as follows /opt/thoroughbred/dpdk/tools/dpdk-pdump -- --pdump 'port=0, queue=*, rx-dev=/boot/partitions/storage/tosfp-pt-dpdk-untrack-fail-00rxtx.01none.02none.03none.pcapng, tx-dev=/boot/partitions/storage/tosfp-pt-dpdk-untrack-fail-00rxtx.01none.02none.03none.pcapng' & It crashes with the following trace EAL: Detected 7 lcore(s) EAL: Detected 1 NUMA nodes PANIC in rte_eal_config_attach(): Cannot open '/var/run/.rte_config' for rte_mem_config 6: [/opt/thoroughbred/dpdk/tools/dpdk-pdump() [0x464e51]] 5: [/lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf5) [0x7f801e50eb45]] 4: [/opt/thoroughbred/dpdk/tools/dpdk-pdump(main+0xeb) [0x45d43b]] 3: [/opt/thoroughbred/dpdk/tools/dpdk-pdump(rte_eal_init+0xde7) [0x4d2527]] 2: [/opt/thoroughbred/dpdk/tools/dpdk-pdump(__rte_panic+0xba) [0x45524d]] 1: [/opt/thoroughbred/dpdk/tools/dpdk-pdump(rte_dump_stack+0x18) [0x4dc928]] What am I doing wrong? Thanks --Srinias
