wish of those help My first guess would simply be that when the client tries to connect, the server thread hasn't really gotten going yet; the client is connecting but nothing is listening. It takes substantial time to create a thread and transfer control to it. You could either sleep before the client connect, or retry it a few times, or get fancy about it and have the server thread signal when the socket is open.

it fixes the issue You should go to router admin console, find something like "port forwarding" and route the port (8081) to your computer IP - you have to say the router that traffic on this port should go to your computer

I wish this helpful for you That's happening because you're starting first your client class and then the server.
You should first run the server and afterwards the client.

will be helpful for those in need Just figured it out. There is actually no problem in the code. The reason why I got an error particularly in the following line is that because just after I installed ubuntu in the virtual box, I changed the device name of the ubuntu without changing the etc/hosts.
code :
hostPtr=gethostbyname(hostname);
if(NULL==hostPtr){
    perror("gethostbyname()");
    exit(1);
}

I hope this helps . You've got two problems. The first is that you're binding to localhost. You probably want to bind to 0.0.0.0 if you want other computers to be able to connect:
