ping command after login

Posted:Mon 30 of Oct, 2006 (08:49 UTC)
I have used the command "sendto(clifd, bufLogin, BUFFER_SIZE, 0, (struct sockaddr_in *)&servaddr, socklen))" in C program and the bufLogin is :"Action: login\r\nUsername: admin\r\nSecret: admin\r\n\r\n" , and the debug message(is "Response: Success
Message: Authentication accepted") of the remote asterisk server shows that i have logined on successfully. Now i again run another command "sendto(clifd, bufPing, strlen(bufPing), 0, (struct sockaddr_in *)&servaddr, socklen))" and the bufPing is "Action: Ping\r\nParameters: None\r\n\r\n" , this time i get the result :Response: Error
Message: Missing action in request" ,and my /var/log/asterisk/full contains the following message:"Oct 30 03:21:43 DEBUG2627 manager.c: Manager received command '' ",the ping command is NULL ? Why? Can someone help me?

thanks in advance... xutom
