Thanks Florin,
I try to run a simple netcat application this time.
On one server I start vpp, vpp status show:

------------------------------------------------
And I set the ip address is 169.254.100.18 on dpdk interface by vpp-config tool.
From another server01 (ip is 169.254.100.17) can ping 169.254.100.18 (this vpp
server) [so I think vpp works now]
But from this server when I do : “sudo
LD_PRELOAD=/home/vpp/build-root/install-vpp-native/vpp/lib64/libvcl_ldpreload.so.0.0.0
netcat -z -v 169.254.100.18 1-100”, it doesn’t work, just show these
following two line:
------
[101553] vcom_init...done!
[101553] vcom_constructor...done!
--------
Without vpp, netcat will return 22, 80 port can be connected.
Do I use vcl preload right? Any instructions for running a native application
by vcl preload?
Thanks!

Hi Chunmei,
The first error says you’re trying to bind multiple times to the same address,
which is not supported. You’re getting the second error because you don’t have
a fib path to the destination of your connect.
Hope this helps,
Florin

Hi all,
I am a novice at vpp, I am trying to use
LD_PRELOAD=/../../libvcl_ldpreload.so to run a native app with vpp, I got the
following error:
vl_api_bind_sock_reply_t_handler:1000: [28874] ERROR: vpp handle 0x0, sid 4:

And :
/usr/bin/vpp[29054]: transport_alloc_local_endpoint:293: no resolving interface
for X.X.X.X
/usr/bin/vpp[29054]: vnet_connect: connect failed
What I missed in configure vpp?
Thanks a lot!
