Cannot run example TCP client or server #109

Closed goliaro closed 5 years ago

Hi! I am running into some errors when trying to run either the TCP server or the TCP client. This is what I am getting: EAL: Detected 4 lcore(s) EAL: Detected 1 NUMA nodes PANIC in rte_eal_config_attach(): Cannot open '/run/user/1000/dpdk/rte/config' for rte_mem_config 7: [./dpdk_tcp_server(_start+0x2a) [0x564a08025bea]] 6: [/lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xe7) [0x7f65af2e0b97]] 5: [./dpdk_tcp_server(main+0x37) [0x564a0801c2c7]] 4: [./dpdk_tcp_server(anssock_init+0x1a2) [0x564a0802a2b2]] 3: [./dpdk_tcp_server(rte_eal_init+0xd47) [0x564a08118f17]] 2: [./dpdk_tcp_server(__rte_panic+0xc5) [0x564a0800c6ec]] 1: [./dpdk_tcp_server(rte_dump_stack+0x2e) [0x564a0812605e]] Aborted (core dumped)

On the other hand, when I run the ans executable using the sample command from the user guide, it seems to go smoothly: `root@ubuntu:~/Desktop/dpdk-ans/ans# ./build/ans -c 0x4 -n 1 -- -p 0x1 --config="(0,0,2)" EAL: Detected 4 lcore(s) EAL: Detected 1 NUMA nodes EAL: Multi-process socket /var/run/dpdk/rte/mp_socket EAL: Probing VFIO support...

Can you help me figure out what's going wrong? Thanks a bunch!!

never mind, I figured it out. I just needed to run the server with sudo or root priviledges.
