Where Proc_Ngi_Voice_New_Accounting is the procedure of accounting stop.

3.clients.conf:

in clients.conf file all the settings related to usr are placed. Radius only

service those request which are coming from listed clients else are ignored.

If you want to add a user then follow this syntax in clients.conf file

client 192.168.2.0 {

secret = testing123

shortname = private-network-1

}

and if you want to allow radius to service request from all clients which are not listed inthe clients.conf file then follow this syntax.

client 0.0.0.0/ {secret = testing123shortname = private-network-1

}

4. In /usr/local/share/freeradius/ all the dictionory files areplaced. Which are used by radius server to look for the requestspecific attributes. And in dictionary.suretech we add our ownattributes the we include this dictionary in dictionary file

$INCLUDE dictionary.suretech

5. /usr/src/modules/rlm_sql


3/12

include.h file contains the attribute which we will use in sql module.For authentication and authorization we use this function.static int rlm_sql_authorize(void *instance, REQUEST * request)we find the attributes with fuction pairfind and it takes two arguments request->packet-

>vps and the other is attribute.Then we copy these attribute in a character array and passing these values to storedprocedure.

if(pair=pairfind(request->packet->vps,PW_CALLING_STATION_ID)){strcpy(callingNumber,pair->strvalue);

printf("\n3: Calling Number is :: %s",callingNumber);

}

else{strcpy(callingNumber,"");

}

int l =

sql_authorizeCall(inst,sqlsocket,userName,pass,callingNumber,authNASIPAddress,a

uthNASPort,authConfID,authServiceType,authNASPortType,accessNumber,calledN

umber,insertSession,v_customerBalance,v_checkItems,v_replyItems,v_callTime,v_ma

rkupCallTime,result);

add this procedure in rlm_sql_module_t struct and it shows like this and it is in rlm_sql.hfile.

int (*sql_voice_authorize)(SQLSOCK *sqlsocket, SQL_CONFIG *config,char

*user1,char *pass1,char *callingNumber,char *authNASIPAddress,char

*authNASPort,char *authConfID,char *authServiceType,char

*authNASPortType,char *accessNumber,char *calledNumber,int *insertSession,char

*v_customerBalance,char *v_checkItems,char *v_replyItems,char *v_callTime,char

*v_markupCallTime,char *result);

add the procedure at the end of the rlm_sql.h file.

int sql_authorizeCall(SQL_INST * inst,SQLSOCK *sqlsocket,char *user1,char

*pass1,char *callingNumber,char *authNASIPAddress,char *authNASPort,char

*authConfID,char *authServiceType,char *authNASPortType,char

*accessNumber,char *calledNumber,int *insertSession,char


4/12


*v_markupCallTime,char *result);

now write the funtion for authorization in sql.c file and call the procedure which u

mentioned in rlm_sql_module_t.

sql_authorizeCall(SQL_INST * inst,SQLSOCK *sqlsocket,char *user1,char

*pass1,char *callingNumber,char *authNASIPAddress,char *authNASPort,char

*authConfID,char *authServiceType,char *authNASPortType,char

*accessNumber,char *calledNumber,int *insertSession,char


*v_markupCallTime,char *result)

{

int procRet=800;

if(inst!=NULL)

{ if(inst->config!=NULL)

{

}

if(inst->module!=NULL)

{

}

}

procRet=(inst->module->sql_voice_authorize)(sqlsocket, inst-

>config,user1,pass1,callingNumber,authNASIPAddress,authNASPort,authConfID,au

thServiceType,authNASPortType,accessNumber,calledNumber,insertSession,v_custo

merBalance,v_checkItems,v_replyItems,v_callTime,v_markupCallTime,result);

return procRet;

}

from here we go to to call the authorize section in

/rlm_sql/drivers/rlm_sql_mysql/sql_mysql.c

static int sql_voice_authorize(SQLSOCK *sqlsocket, SQL_CONFIG *config,char

*user1,char *pass1,char *callingNumber,char *authNASIPAddress,char

strcat(result,mysql_error(conn));

}

else

{

}

res = mysql_use_result(conn);

if(res==NULL)

{

}

else

{

}


6/12

mysql_free_result(res);

int ret=400;

while(mysql_more_results(conn))

{ int next=mysql_next_result(conn);

res = mysql_use_result(conn);

if(res==NULL)

{

}

else

{

int num=mysql_num_rows(res);

while ((row = mysql_fetch_row(res)) != NULL)

{ ret=atoi(row[0]);

strcpy(v_customerBalance,row[1]);

strcpy(v_checkItems,row[2]);

strcpy(v_replyItems,row[3]);

strcpy(v_callTime,row[4]);

strcpy(v_markupCallTime,row[5]);

}


}

mysql_close(conn);

return ret;

}

in this file we make the connection with database and call the procedure and return thevalues to rlm_sql.c file.If return code is zero then it authorizes then we return the values to the client by paircreatemethod.then we sent this value to pairadd method.


7/12

ret_code = paircreate(quintum_h323_return_code,PW_TYPE_STRING);if(ret_code!=NULL){

//ret_code->lvalue=l;char t[30];

sprintf(t,"h323-return-code=%d",l);strcpy(ret_code->strvalue,t);ret_code->length=strlen(ret_code->strvalue);pairadd(&reply_tmp, ret_code);

}

then we send this value to the client by using this function.

pairxlatmove(request, &request->reply->vps, &reply_tmp);

similary if there is no called number then it will authenticate the customer.int l = sql_AuthenticateCall(inst,sqlsocket,userName,pass,callingNumber,authNASIPAddress,authNASPort,authConfID,authServiceType,authNASPortType,accessNumber,v_customerBalance,v_pref_lang,result);

then we will add it in rlm_sql.h in rlm_sql_module_tandint (*sql_authen)(SQLSOCK *sqlsocket, SQL_CONFIG *config,char *user,char*pass,char *callingNumber,char *authNASIPAddress,char *authNASPort,char*authConfID,char *authServiceType,char *authNASPortType,char *accessNumber,char*v_customerBalance,char *v_pref_lang,char *result);

and at the end of this rlm_sql.h add this line

int sql_AuthenticateCall(SQL_INST * inst, SQLSOCK * sqlsocket,char *user,char*pass,char *callingNumber,char *authNASIPAddress,char *authNASPort,char*authConfID,char *authServiceType,char *authNASPortType,char *accessNumber,char*v_customerBalance,char *v_pref_lang,char *result);

and add the funtion in sql.c which will call the authenticate funtion in/drivers/rlm_sql/mysql_mysql.c.

sql_AuthenticateCall(SQL_INST * inst, SQLSOCK * sqlsocket,char *user,char *pass,char*callingNumber,char *authNASIPAddress,char *authNASPort,char *authConfID,char*authServiceType,char *authNASPortType,char *accessNumber,char*v_customerBalance,char *v_pref_lang,char *result){

int procRet=800;if(inst!=NULL){


8/12

if(inst->config!=NULL){}

if(inst->module!=NULL)

{}

}procRet=(inst->module->sql_authen)(sqlsocket, inst-

>config,user,pass,callingNumber,authNASIPAddress,authNASPort,authConfID,authServiceType,authNASPortType,accessNumber,v_customerBalance,v_pref_lang,result);

return procRet;}

this fuction takes us to the authenticate function in /drivers/rlm_sql/mysql_mysql.c.

where we authenticate the customer with the stored procedure CALLProc_Ngi_Voice_Authentication and it will returns the return code,customer balance andprefereed language. If return code 0 then customer authenticate other wise there is errorthen we send this value to the client as did in authorize section.

Accounting: First of all find the attributes in accounting section then copy it to the somechar array. Then we check account status type and in our request account status type is stopthen it will go to the stop section. Where it calls the function

retcode=sql_Accounting_stop_voice_call(inst,sqlsocket,"time",userName,pass,callDuration,callingNumber,calledNumber,confId,callOrigin,callType,acctSessionId,NASIPAddress,bytesIn,bytesOut,delayTime,acctSType,remoteAddress,remoteGwId,terminationCause,srcPort,destPort,accessNumber,callLeg1,callLeg2,callLeg3,callLeg4,result);

form here this function add in rlm_sql.h. then in sql.c where we call the procedure andexecute it.

retcode=sql_Accounting_stop_voice_call(inst,sqlsocket,"time",userName,pass,callDuration,callingNumber,calledNumber,confId,callOrigin,callType,acctSessionId,NASIPAddress,bytesIn,bytesOut,delayTime,acctSType,remoteAddress,remoteGwId,terminationCause,srcPort,destPort,accessNumber,callLeg1,callLeg2,callLeg3,callLeg4,result);

Then we add in rlm_sql.h in rlm_sql_module_t struct.

int (*sql_Accounting_stop_voice)(SQLSOCK *sqlsocket, SQL_CONFIG *config,char*timeclose,char *userName,char *password,int *callDuration,char *callingNumber,char


9/12

*calledNumber,char *confId,char *callOrigin,char *callType,char *acctSessionID,char*NASIPAddress,int *bytesIn,int *bytesOut,int *delayTime,char *acctSType,char*remoteAddress,char *remoteGwID,char *terminationCause,char *srcPortNo,char*destPortNo,char *accessNumber,int *callLeg1,int *callLeg2,int *callLeg3,int*callLeg4,char *result);

and at the end of file

int sql_Accounting_stop_voice_call(SQL_INST * inst,SQLSOCK * sqlsocket,char*timeclose,char *userName,char *password,int *callDuration,char *callingNumber,char*calledNumber,char *confId,char *callOrigin,char *callType,char *acctSessionID,char*NASIPAddress,int *bytesIn,int *bytesOut,int *delayTime,char *acctSType,char*remoteAddress,char *remoteGwID,char *terminationCause,char *srcPortNo,char*destPortNo,char *accessNumber,int *callLeg1,int *callLeg2,int *callLeg3,int*callLeg4,char *result);

and in sql.c add the following function.

sql_Accounting_stop_voice_call(SQL_INST * inst,SQLSOCK *sqlsocket,char*timeclose,char *userName,char *password,int *callDuration,char *callingNumber,char*calledNumber,char *confId,char *callOrigin,char *callType,char *acctSessionID,char*NASIPAddress,int *bytesIn,int *bytesOut,int *delayTime,char *acctSType,char*remoteAddress,char *remoteGwID,char *terminationCause,char *srcPortNo,char*destPortNo,char *accessNumber,int *callLeg1,int *callLeg2,int *callLeg3,int*callLeg4,char *result){

int procRet10=800;

if(inst!=NULL){

if(inst->config!=NULL){}

if(inst->module!=NULL){}

}procRet10=(inst->module->sql_Accounting_stop_voice)(sqlsocket, inst-

>config,timeclose,userName,password,callDuration,callingNumber,calledNumber,confId,callOrigin,callType,acctSessionID,NASIPAddress,bytesIn,bytesOut,delayTime,acctSType,remoteAddress,remoteGwID,terminationCause,srcPortNo,destPortNo,accessNumber,callLeg1,callLeg2,callLeg3,callLeg4,result);


10/12

return procRet10;

}

now go to the /drivers/rlm_sql_mysql/sql_mysql.c function.

static int sql_Accounting_stop_voice(SQLSOCK *sqlsocket, SQL_CONFIG *config,char*timeclose,char *userName,char *password,int *callDuration,char *callingNumber,char*calledNumber,char *confId,char *callOrigin,char *callType,char *acctSessionID,char*NASIPAddress,int *bytesIn,int *bytesOut,int *delayTime,char *acctSType,char*remoteAddress,char *remoteGwID,char *terminationCause,char *srcPortNo,char*destPortNo,char *accessNumber,int *callLeg1,int *callLeg2,int *callLeg3,int*callLeg4,char *result){

MYSQL *conn;

MYSQL_RES *res;MYSQL_ROW row;char *server = config->sql_server;char *user = config->sql_login;char *dbpassword = config->sql_password;//char *database = "ngi";char *database = config->sql_db;

conn = mysql_init(NULL);

if (!mysql_real_connect(conn, server,user, dbpassword, database, 0, NULL,CLIENT_MULTI_RESULTS | CLIENT_MULTI_STATEMENTS))

{strcat(result,mysql_error(conn));

}char stf[1000];

int n=sprintf (stf, "CALL%s( '%s','%s','%d','%s','%s','%s','%s','%s','%s','%s','%d','%d','%d','%s','%s','%s','%s','%s','%s','%s','%d','%d','%d','%d',@ret ); select @ret",config->accounting_stop_query,userName,password,callDuration,callingNumber,calledNumber,confId,callOrigin,callType,acctSessionID,NASIPAddress,bytesIn,bytesOut,delayTime,acctSType,remoteAddress,remoteGwID,terminationCause,srcPortNo,destPortNo,accessNumber,callLeg1,callLeg2,callLeg3,callLeg4);

printf("\n\nQuery To Execute: %s \n",stf);strcat(result,stf);

int sta =mysql_real_query(conn, stf,strlen(stf));if (sta)


11/12

{strcat(result,mysql_error(conn));

}else{

}

res = mysql_use_result(conn);if(res==NULL){}else{}


int ret=400;while(mysql_more_results(conn)){

int next=mysql_next_result(conn);res = mysql_use_result(conn);if(res==NULL){}else{}

int num=mysql_num_rows(res);while ((row = mysql_fetch_row(res)) != NULL){

ret=atoi(row[0]);}

mysql_free_result(res);}

mysql_close(conn);

return ret;}

and it will execute the query which is mentioned in accounting_stop_query in sql.conf.


12/12

then it will return the value to the radius clients.
