Hi,
There are 3 computers, one server and two endpoints, as follows
version: pjproject-2.7.2
environment: ubuntu 14.04/16.04
server: 172.17.13.8 (sipserver stun/turn server)
client1: 172.17.13.222, registered successful with sip:101@172.17.13.8
client2: 192.168.1.103 (a routing sub-network behind 172.17.13.3), registered sip:102@172.17.13.8
while client1 makes a call to client2 using ICE with configuration,
client1: ./pjsua-x86_64-unknown-linux-gnu --id sip:101@172.17.13.8 --registrar sip:172.17.13.8 --realm 172.17.13.8 --username 101 --password 101 --stun-srv=172.17.13.8 --use-ice --use-turn --turn-srv=172.17.13.8:3488 --turn-user username1 --turn-passwd password1
client2: ./pjsua-x86_64-unknown-linux-gnu --id sip:102@172.17.13.8 --registrar sip:172.17.13.8 --realm 172.17.13.8 --username 102 --password 102 --stun-srv=172.17.13.8 --use-ice --use-turn --turn-srv=172.17.13.8:3488 --turn-user username2 --turn-passwd password2
*len = recvfrom(sock, (char*)buf, *len, flags,
(struct sockaddr*)from, (socklen_t*)fromlen);
the function recvfrom() (in sock_bsd.c: pj_sock_recvfrom()) always return -1 and errno is 11(EAGAIN), but after read the data of received buffer is correct that compared with the tcpdump data. Why is it wrong to return -1 and buffer data is right?
However, if client2 is in upper level network directly and configure with ip 172.17.13.114, then client1 makes a call to client2, it can received the invite messgae(INVITE sip:102@172.17.13.114:5060;ob SIP/2.0 Record-Route: <sip:172.17.13.8;r2=on;lr;nat=yes;did=04e.d39fa1e1> ...), and return value(1899 bytes), the length received, is right. it's always right.
Thanks,
Qing.zou
