Tutorial

1. Build

$ git clone git@github.com:pandax381/microps.git$ cd microps$ make

2. Prepare Tap device

$ sudo ip tuntap add mode tap user $USER name tap0$ sudo ip addr add 192.0.2.1/24 dev tap0$ sudo ip link set tap0 up

3. Run sample application

$ ./app/tcps.exe 711:48:55.884 [I] net_protocol_register: registerd, type=ARP(0x0806) (net.c:223)11:48:55.884 [I] net_timer_register: registerd: ARP Timer interval={1, 0} (net.c:257)11:48:55.884 [I] net_protocol_register: registerd, type=IP(0x0800) (net.c:223)...11:48:55.884 [D] net_run: running... (net.c:324)11:48:55.884 [D] tcp_bind: success: addr=0.0.0.0, port=7 (tcp.c:1156)

4. Test (Operate in another terminal)

$ ping 192.0.2.2PING 192.0.2.2 (192.0.2.2) 56(84) bytes of data.64 bytes from 192.0.2.2: icmp_seq=1 ttl=255 time=0.660 ms64 bytes from 192.0.2.2: icmp_seq=2 ttl=255 time=0.688 ms64 bytes from 192.0.2.2: icmp_seq=3 ttl=255 time=0.574 ms...
