RunningNow we can compile this and link it, by runninggcc -c -o main.o -I../picotcp/build/include main.cgcc -o main.elf main.o ../picotcp/build/lib/libpicotcp.aNext we'll create a persistent tap device - a virtual network port. You don't need to repeat this each time, the device will exist until you reboot, or until you go sudo tunctl -d tap0sudo ifconfig tap0 192.168.5.5">sudo tunctl -u username>sudo ifconfig tap0 192.168.5.5Now, you should be able to run ./main.elf, and see output likeProtocol ethernet registered (layer: 2).Protocol ipv4 registered (layer: 3).Protocol ipv6 registered (layer: 3).Protocol icmp4 registered (layer: 4).Protocol icmp6 registered (layer: 4).Protocol igmp registered (layer: 4).Protocol udp registered (layer: 4).Protocol tcp registered (layer: 4).Device tap0 created.Assigned ipv4 192.168.5.4 to device tap0starting ping64 bytes from 192.168.5.5: icmp_req=1 ttl=64 time=5 ms64 bytes from 192.168.5.5: icmp_req=2 ttl=64 time=0 ms64 bytes from 192.168.5.5: icmp_req=3 ttl=64 time=0 ms64 bytes from 192.168.5.5: icmp_req=4 ttl=64 time=0 ms64 bytes from 192.168.5.5: icmp_req=5 ttl=64 time=0 ms64 bytes from 192.168.5.5: icmp_req=6 ttl=64 time=0 ms64 bytes from 192.168.5.5: icmp_req=7 ttl=64 time=0 ms64 bytes from 192.168.5.5: icmp_req=8 ttl=64 time=0 ms64 bytes from 192.168.5.5: icmp_req=9 ttl=64 time=0 ms64 bytes from 192.168.5.5: icmp_req=10 ttl=64 time=0 msfinished !While the application is running, you can also runto send pings in the other direction.Investigating what happenedRun wireshark, and sniff the tap0 interface. Then run the ./main.elf again, and see what happens. You should see an ARP request from picoTCP to Linux, and a reply. After that you should see the ping requests and replies going back and forth.Note, sometimes you may see lots of other stuff,

Nothing screams out good network engineer than some proficiency in Wireshark. In this post we will go through what Wireshark is, how it can help you, and some basics.What is Wireshark?Wireshark is a packet capture utility available for Windows and Mac OSX (along with ports for Linux). This allows you to capture the network traffic between two devices.You can download Wireshark from started with WiresharkI am using UNetLab here, which offers great Wireshark integration.Check this link for Wireshark integration on OSX.We have a simple topology, running RIP, OSPF and EIGRP. We will be capturing the traffic coming in and out of Client:With this set up we should see some good traffic!The configurations are below:RIP1(config)#int gi 0/0RIP1(config-if)#ip add 10.10.1.120 255.255.255.0RIP1(config-if)#int lo0RIP1(config-if)#ip add 120.120.120.120 255.255.255.255RIP1(config-if)#RIP1(config-if)#router ripRIP1(config-router)#network 10.10.1.0RIP1(config-router)#network 120.120.120.120 RIP1(config-router)#OSPF1(config)#int gi 0/0OSPF1(config-if)#ip add 10.10.1.88 255.255.255.0OSPF1(config-if)#no shutOSPF1(config-if)#int lo0OSPF1(config-if)#ip add 88.88.88.88 255.255.255.255 OSPF1(config-if)#ip ospf network point-to-point OSPF1(config-if)# OSPF1(config-if)#router ospf 1OSPF1(config-router)#network 10.10.1.88 0.0.0.0 area 0OSPF1(config-router)#network 10.10.1.88 0.0.0.0 area 0OSPF1(config-router)#EIGRP1(config)#int gi 0/0EIGRP1(config-if)#ip add 10.10.1.89 255.255.255.0EIGRP1(config-if)#no shutEIGRP1(config-if)#int lo0EIGRP1(config-if)#ip add 89.89.89.89 255.255.255.255EIGRP1(config-if)#EIGRP1(config-if)#router eigrp 1EIGRP1(config-router)#network 10.10.1.89 0.0.0.0EIGRP1(config-router)#network 89.89.89.89 0.0.0.0EIGRP1(config-router)#Client(config)#int gi 0/0Client(config-if)#ip add 10.10.1.10 255.255.255.0Client(config-if)# Client(config-if)#int lo0Client(config-if)#ip add 10.10.10.10 255.255.255.255Client(config-if)#ip ospf network point-to-point Client(config-if)#Client(config)#router ripClient(config-router)#network 10.10.1.0Client(config-router)#network 10.10.10.0 Client(config-router)#no autoClient(config-router)#Client(config-router)#router ospf 1Client(config-router)#network 10.10.1.10 0.0.0.0 area 0Client(config-router)#network 10.10.10.10 0.0.0.0 area 0Client(config-router)#Client(config-router)#router eigrp 1Client(config-router)#network 10.10.1.10 0.0.0.0Client(config-router)#network 10.10.10.10 0.0.0.0Client(config-router)#Client(config-router)#The interfaces are currently shutdown on RIP1, OSPF1, EIGRP1 and Client.

We should see something similar to this:You can download this file from: can see traffic for EIGRP, OSPF and RIP (amongst other traffic). But like this it is hard to really dig into anything in particular. So, we can filter our traffic.Filtering in WiresharkAt the top of the Wireshark window is a box that says "Apply a display filter..." If we click in that, we can enter something to filter on.Click in the box and type in rip. You should see the box go green, along with an option for "ripng". We are just interested in RIP for the moment, so just press return:If we wanted to look at just the OSPF traffic, we can change the filter to "ospf":Similarly for EIGRP:If the box is green, the query is clean (to paraphrase Ghostbusters)!What
