Need a way to send a string to a Windows socket 1

[cxnoel]

Hi. I don't know much about Unix and I am not a C programmer. I need a little someting that can send a string to a remote machine using a socket channel. Is there any program that can be used for this which will accept a command like this: SendTo host port message

I found lot of C example using the Berkely Socket API but as I said, I am not a C programmer on Unix. I just need my Unix server be able to send a string on an already opened channel on my Windows NT server.

If anyone can help me, it will be greatly appreciated.

Thanks.

I wouldn't think you need C to do this. Try asking this question in the Perl forum: forum219, or in the Unix Scripting forum: forum822

its quite a simple prog in c but you need to understand a little C. In fact you don't need to code, you can telnet to your port and send you message, thats awful but should work.
tell me if you want some code in C.

Well, Telnet is not suitable for my needs. If you have a compiled C program (or any other language) that I can use by passing 3 parameters (host, port, message), it will be appreciated.

Thank you very much.

Can you send me a compiled program that I can use by using 3 parameters: host, port & message. Telnet is not suitable for my needs.

Thank you very much.

No, I'm sorry but I don't have time to write programs for you, that's why I suggested you ask your question in one of the scripting forums. Mike

copy everything under in toto.c then do a make toto. (please pay attention not to cut lines).

bzero((char *) &serv_addr, sizeof(serv_addr));

serv_addr.sin_addr.s_addr = inet_addr(argv[1]);
port = atoi(argv[2]);
printf(&quot; Le port cible est : %i \n\n&quot;, port);
serv_addr.sin_port = htons(port);
if ((sockfd = socket(AF_INET, SOCK_STREAM, 0)) < 0)

if (send(sockfd, argv[3], sizeof(argv[3]), 0) < 0)

Merci beaucoup! It works great!
