[INFO](re)sent tcp syn和received syn,sent syn ack back的解决方法

Open godwasdog opened this issue 5 years ago • 7 comments

客户端出现大量 INFOsent tcp syn INFOsent tcp syn INFOsent tcp syn INFOsent tcp syn [INFO]state back to client_idle from client_tcp_handshake [INFO]using port 32030 [INFO]state changed from client_idle to client_tcp_handshake INFOsent tcp syn INFOsent tcp syn INFOsent tcp syn INFOsent tcp syn INFOsent tcp syn

然后服务器端出现大量 [INFO][ip:11022]received syn,sent syn ack back [INFO][ip:11022]received syn,sent syn ack back [INFO][ip:11022]received syn,sent syn ack back [INFO][ip:11022]received syn,sent syn ack back [INFO][ip:11022]received syn,sent syn ack back [INFO][ip:11022]received syn,sent syn ack back

不用清空iptables 添加 iptables -I OUTPUT -p tcp --sport 监听端口 -j ACCEPT

我出现的问题解决。仅供参考

I think this issue might be the right one. Running udp2raw on a x64 debian based machine as a client and a arm based openwrt router as the server. Command from the client: sudo ./udp2raw_amd64 -c -l0.0.0.0:3333 -r 192.168.210.1:4096 --raw-mode faketcp -a Command from the server: ./udp2raw_arm -s -l0.0.0.0:4096 -r 127.0.0.1:7777 --raw-mode faketcp -a I always get the message described in the title if I use faketcp as the raw-mode. If I choose udp or icmp, everything's running perfectly well.
