Hi,

I have written a C code which would let me connect to the Asterisk Manager
Interface. The code compiles successfully but on running the code I get
unauthorized login shown in the Asterisk command line console.

Here is my C code:

#include<stdio.h>
#include<netdb.h>
#include<unistd.h>
#include<string.h>
#include<arpa/inet.h>
#include<sys/types.h>
#include<sys/socket.h>
#include<netinet/in.h>

#define MAX_MSG_SIZE 512
#define SERVER_ADDRESS "192.168.0.150"
#define CLIENT_ADDRESS "192.168.0.150"
#define SERVER_PORT 5038
#define CLIENT_PORT 5100

int main()
{
int sd;
struct sockaddr_in serveraddr, clientaddr;
char msg[MAX_MSG_SIZE];

bzero((char *) &serveraddr, sizeof(serveraddr));
serveraddr.sin_family = AF_INET;
serveraddr.sin_addr.s_addr = inet_addr(SERVER_ADDRESS);
serveraddr.sin_port = htons(SERVER_PORT);

bzero((char *) &clientaddr, sizeof(clientaddr));
clientaddr.sin_family = AF_INET;
clientaddr.sin_addr.s_addr = INADDR_ANY;
clientaddr.sin_port = htons(CLIENT_PORT);

sd = socket(AF_INET, SOCK_STREAM, 0);
printf("\nCreated socket ...");

bind(sd,(struct sockaddr *) &clientaddr, sizeof(clientaddr));
printf("\nBinding successful ...");

connect(sd,(struct sockaddr *) &serveraddr, sizeof(serveraddr));
printf("\nConnected ...");

*msg=(char)"Action: Login\r\nUsername: admin\r\nSecret:
admin\r\nActionID: 1\r\n\r\n";
send(sd,msg,strlen(msg)+1,0);
close(sd);

return(1);
}

Please correct me where I am going wrong. In manager.conf the username and
secret has been defined.
Thank you.

Hi, I believe your problem of authorization is relative to astersik's manager.conf configuration and you need to add and user and password in the manager.conf to have remote access. I have used some examples of voip-info.org, look at this link in the second half part, it explain how to configure the manager.conf file.

http://www.voip-info.org/wiki/view/Asterisk%20Zaptel%20Nagios%20plugin

# You need a manager entry in /etc/asterisk/manager.conf

# [nagios]

# secret=somesecret

# deny=0.0.0.0/0.0.0.0

# permit=127.0.0.0/255.0.0.0

# permit=111.222.333.444/255.255.255.111 <-- the network nagios connects from

# read = system,call,log,verbose,command,agent,user

# write = system,call,log,verbose,command,agent,user
and in this other link, you can find the Manager API and another examples:

Hi,

I have written a C code which would let me connect to the Asterisk Manager Interface. The code compiles successfully but on running the code I get unauthorized login shown in the Asterisk command line console.

Here is my C code:

#include<stdio.h>
#include<netdb.h>
#include<unistd.h>
#include<string.h>
#include<arpa/inet.h>

#define SERVER_ADDRESS "192.168.0.150"
#define CLIENT_ADDRESS "192.168.0.150"
#define SERVER_PORT 5038
#define CLIENT_PORT 5100

int main()
{
int sd;
struct sockaddr_in serveraddr, clientaddr;
char msg[MAX_MSG_SIZE];

bzero((char *) &serveraddr, sizeof(serveraddr));
serveraddr.sin_family = AF_INET;
serveraddr.sin_addr.s_addr = inet_addr(SERVER_ADDRESS);
serveraddr.sin_port = htons(SERVER_PORT);

bzero((char *) &clientaddr, sizeof(clientaddr));
clientaddr.sin_family = AF_INET;

clientaddr.sin_port = htons(CLIENT_PORT);

sd = socket(AF_INET, SOCK_STREAM, 0);
printf("\nCreated socket ...");

bind(sd,(struct sockaddr *) &clientaddr, sizeof(clientaddr));
printf("\nBinding successful ...");

connect(sd,(struct sockaddr *) &serveraddr, sizeof(serveraddr));

*msg=(char)"Action: Login\r\nUsername: admin\r\nSecret: admin\r\nActionID: 1\r\n\r\n";
send(sd,msg,strlen(msg)+1,0);

}



Please correct me where I am going wrong. In manager.conf the username and secret has been defined.
Thank you.
