Jajodia-Mutchler

The final project for the "Advanced Operating Systems" course (CS6378) (taught by Ravi Prakash), in which we implement the Jajodia-Mutchler algorithm.

How to compile

Controller

g++ --std=c++11 -pthread controller.cpp -o control

Servers

g++ -pthread --std=c++11 include/serversocket.cpp include/clientsocket.cpp include/socket.cpp server.cpp -o server

How to run

Activate the servers before the controller.

Servers

server_designation is an integer between [0, 7]. Update the ip address and ports in the servers object in the commons.h file.

./server <server_port> <server_designation>

Controller

./control

What goes in the commons.h file?

You must put in the external IP address in the commons.h file. You can use ifconfig to figure that out. When I run ifconfig on one of my servers, I get a response similar to what is shown below...

kgupta@ecelap261053 → ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet <***.***.***.***>  netmask 255.255.240.0  broadcast <***.**.***.***>
        inet6 <****::****:****:****:****>  prefixlen 64  scopeid 0x20<link>    
        ether <**:**:**:**:**:**>  txqueuelen 1000  (Ethernet)
        RX packets 17  bytes 2613 (2.6 KB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 10  bytes 796 (796.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

That means that I use the inet value of eth0 for the server IP address, and any free port for the port number.

If you take this course in the future and you get this exact same assignment, then I gotchu covered fam.
