thank you benoit. Also i just understood that hoststack built in echo works different from external echo app, so i tried this on the same vm session - (does built-in mean using client and server in same vm session? also built in echo does not support the use-svm-api option , still gave a shot):
-bash-4.2$ sudo /auto/home.nas04/skesavan/vpp/build-root/install-vpp_debug-native/vpp/bin/vpp -c /etc/vpp/startup.conf -bash-4.2$ sudo /auto/home.nas04/skesavan/vpp/build-root/install-vpp_debug-native/vpp/bin/vppctl -s /run/vpp/cli.sock sh int addr host-vpp1 (up): L3 10.0.0.1/24 local0 (dn): -bash-4.2$ sudo /auto/home.nas04/skesavan/vpp/build-root/install-vpp_debug-native/vpp/bin/vppctl test echo server uri tcp://10.0.0.1/1237 -bash-4.2$ sudo /auto/home.nas04/skesavan/vpp/build-root/install-vpp_debug-native/vpp/bin/vppctl test echo client uri tcp://10.0.0.1/1237 unexpected event(1): 0 test failed test echo clients: failed: unexpected event(1): 0 -bash-4.2$ nc -zv 10.0.0.1 1237 Ncat: Version 7.50 ( https://nmap.org/ncat ) Ncat: Connection timed out. DBGvpp# show errors Count Node Reason 31 session-queue Packets transmitted 31 ip4-local ip4 spoofed local-address packet drops couple of conceptual questions: 1. why will netcat not work here - since it is a local ip? 2. how is built in echo app different from external echo app? 3. should i be running two instances of the same vpp service in one sesison connected to my vm to test the echo client app?
