int client_socket = socket(AF_INET,SOCK_STREAM,0);

if (client_socket < 0) { printf(“unable to create socket %dn”, stderr); return 0; } struct sockaddr_in remote_address; remote_address.sin_family = AF_INET; remote_address.sin_port = htons(80); inet_aton(address,&remote_address.sin_addr.s_addr); int con_ret = connect(client_socket,(struct sockaddr_in *)&remote_address,sizeof(remote_address)); if (0 == con_ret) { char request[]=”GET /HTTP/1.1rnrn”; char response[4096]; send(client_socket,request,sizeof(request),0); recv(client_socket,&response,sizeof(response),0); printf(“Response from the server: %sn”,response); close(client_socket); } return 0; } If I run this code in ubuntu getting 503 error and sometime 400 error.please correct me where I did the mistake.

worked (ref:

Sloba Ivkovic says:

Excellent series, really enjoyed watching it, only 2 videos though, I see that there are not so much views on this video so I suspect that this series is not going to be extended which is really a shame, this is best socket C programming basics video I found so far and it would be nice to see what can be build on top of it. Thanks

Hamza bozbaş says:

great series, i think next thing that u should do is to make a series for web apis in c. that would be greaat. im looking forward for it. im unable to find any resource for that on internet

Fuangel Sikarin says:

1 question, I can get response 200ok when I run code in my home but when I go another place like university I always get 302 found . In same address (but local server it’s work every where)
thank you

Quaylyn Rimer says:

I got the same code you put I had to add #include for the close() to work after the tutorial on this video I was not able to pull it up in my browser any idea? I am running Ubuntu 17.04

Anupama Sodhi says:

Hey! When I try to open the page on the browser, it shows a blank page :3 help!

Ronny Landsverk says:

It seems many have problems with the http server when using a browser as a client.
I can “telnet” to the server, e.g. “telnet localhost 8001” and get response

HTTP/1.1 200 OK
welcome to HTTP server

but when i connect via a browser (localhost:8001) the browser is blank…
However, when replacing close() with pclose(), then the browser will display the html code.
Why ? BTW I use Cygwin64 and the compiler warned about close()…

anupam karn says:

how to print the whole entity body (i.e “last modified, date etc”) in server response?

will9020 says:

Awesome video! I’m working on the HTTP_Client project and when i run the code, i get a “segmentation fault” error… Any ideas? I’m running Ubuntu 18
