Accounting data not read from openvpn-status.log (OpenVPN version 2.5). Added solution.

[Le-Inc]

Because (current) OpenVPN 2.5 has different status log than the version used to compile radiusplugin no bytes sent/received is read from openvpn-status.log file. I changed in AcctScheduler.cpp file method parseStatusFile, so radiusplugin could parse file. Code:

void AcctScheduler::parseStatusFile(PluginContext *context, uint64_t *bytesin, uint64_t *bytesout, string key)
{
	char line[512], newline[512];
	memset(newline, 0, 512);
	string AddKey;
	char* RowVals[9];
	int i;
	
	//open the status file to read
	ifstream file(context->conf.getStatusFile().c_str(), ios::in);
	if (file.is_open())
	{
		if (DEBUG (context->getVerbosity()))
			 cerr << getTime() << "RADIUS-PLUGIN: BACKGROUND ACCT: Scheduler: Read Statusfile.\n";
	  	
	  	//find the key, is delimited with a ',' from the informations
	  	
	  	//loop until the name is found, there is no delimiter, the string
	  	//"ROUTING TABLE" is found or EOF
		
        // Added CLIENT_LIST as OpenVPN status-log format has changed.
		AddKey = "CLIENT_LIST,"+key;
		i = 0;

		do
		{
			file.getline(line, 512);
			
		}
		while (line!=NULL && strncmp(line,AddKey.c_str(),AddKey.length())!=0 && strcmp(line,"HEADER,ROUTING_TABLE,Virtual Address,Common Name,Real Address,Last Ref,Last Ref (time_t)")!=0 && file.eof()==false);
		
		if (line!=NULL && strncmp(line,AddKey.c_str(),AddKey.length())==0) {
		  memcpy(newline, line+AddKey.length(), strlen(line)-AddKey.length()+1);
		  char* res =  strtok(newline, ",");
		  while (res != NULL) {
		    RowVals[i] = res;
                    res = strtok(NULL, ",");
		    i = i + 1;
          }
		  *bytesin=strtoull(RowVals[1],NULL,10);
		  *bytesout=strtoull(RowVals[2],NULL,10);

		} else {
			cerr << getTime() << "RADIUS-PLUGIN: BACKGROUND ACCT: No accounting data was found for "<< key << " in file " << context->conf.getStatusFile() << endl;
		}

		file.close();
	}
	else
	{
		cerr << getTime() << "RADIUS-PLUGIN: BACKGROUND-ACCT: Statusfile "<< context->conf.getStatusFile() <<" could not opened.\n";
	}
}
