I have written a custom UniMRCP ASR plugin and wanted it to work with Voximal on Asterisk.
I followed the doc here: https://wiki.voximal.com/doku.php?id=asrproviders:unimrcp.
The VXML works fine but, when I try to record in VXML, I can't see any stream being sent to the UniMRCP server. My UniMRCP server and Asterisk are both on the same machine. I've tried the Voxibot installation installation on EC2 too but encountered the same issue
Below are some of the configurations in Asterisk:

I don't see the link between the ASR and the record feature (used to record the user's voice without .
If you want to record the audio flow sent to the ASR, you can use the property "recordutterance" (true/false), you will have a shadow variable field_name$.recording, field_name$.recordingsize, field_name$.recordingduration.

I'm trying to get the data stream of a sensor transmitter that uses the modbus rtu communication protocol on my raspberry pi 3B. I'm able to get the data with the pymodbus2.5.3 library.
For this I use this code:
from pymodbus.client.sync import ModbusSerialClient # Import the pymodbus library part for syncronous master (=client)
client = ModbusSerialClient(
method='rtu', #Modbus Modus = RTU = via USB & RS485
port='/dev/ttyUSB0', #Connected over ttyUSB0, not AMA0
baudrate=19200, #Baudrate was changed from 38400 to 19200
timeout=3, #
parity='N', #Parity = None
stopbits=2, #Bites was changed from 1 to 2
bytesize=8 #
)
if client.connect(): # Trying to connect to Modbus Server/Slave
#Reading from a holding register
res = client.read_holding_registers(address=100, count=8, unit=1) #Startregister = 100, Registers to be read = 8, Answer size = 1 byte
if not res.isError(): #If Registers don't show Error
print(res.registers) #Print content of registers
else:
print(res) #Print Error Message, for meaning look at (insert git hub)
else: #If not able to connect, do this
print('Cannot connect to the Transmitter M80 SM and Sensor InPro 5000i.')
print('Please check the following things:')
print('Does the RS485-to-USB Adapter have power? Which LEDs are active?')
print('Are the cables connected correctly?')
And get the following output:
[15872, 17996, 16828, 15728, 16283, 45436, 16355, 63231]
With the help of the Modbus Poll and Slave Programms I know that those results should decoded be:
[0.125268, --, 23.53, --, 1.21094, --, 1.77344, --]
To get to the right results I tried the command that the pymodbus github suggests .decode():
res.decode(word_order = little, byte_order = little, formatters = float64)
[I know that those aren't the needed options but I copied the suggested github code to check if it works.]
After putting the code segment into the code the changed part looks like this:
if not res.isError(): #If Registers don't show Error
res.decode(word_order = little, byte_order = little, formatters = float64)
print(res.registers) #Print content of registers
else:
print(res) #Print Error Message, for meaning look at (insert git hub)
When I run this code, I get the following output, that traces to the decoding segment:
NameError: name 'little' is not defined
After this, I imported also the pymodbus part translation. But it showed the same output.
How can I decode my incoming data?
You can use BinaryPayloadDecoder to help decoding your payload, here is a simplified example, change Endian.Big and Endian.Little if needed.
if client.connect(): # Trying to connect to Modbus Server/Slave
#Reading from a holding register
res = client.read_holding_registers(address=100, count=8, unit=1) #Startregister = 100, Registers to be read = 8, Answer size = 1 byte
# ====== added code start ======
decoder = BinaryPayloadDecoder.fromRegisters(res.registers, Endian.Little, wordorder=Endian.Little)
first_reading = decoder.decode_32bit_float()
second_reading = decoder.decode_32bit_float()
# ====== added code end ======
if not res.isError(): #If Registers don't show Error
print(res.registers) #Print content of registers
else:
print(res) #Print Error Message, for meaning look at (insert git hub)
Remember to import from pymodbus.payload import BinaryPayloadDecoder at top and add necessary exception handlers in your final code.

Collectd queries nginx's HttpStubStatusModule
in order to find the active connections.
The config end looks like-
<Plugin "nginx">
URL "https://localhost:8433/nginx_status"
</Plugin>
The plugin is here.
i have a setup wherein i have 4 Nginx instances running on the same physical host, each listening at a different port. How do i make collectd monitor multiple Nginxes? The following does not work-
<Plugin "nginx">
URL "https://localhost:8433/nginx_status"
</Plugin>
<Plugin "nginx">
URL "https://localhost:8434/nginx_status"
</Plugin>
I have written a small script for the collectd Python plugin:
https://github.com/magazov/collectd-multinginx-python
It is very simple to use.
Here is the source code:
#! /usr/bin/env python
import re
import urllib2
import collectd
class Nginx(object):
def __init__(self):
self.pattern = re.compile("([A-Z][\w]*).+?(\d+)")
self.urls = {}
def do_nginx_status(self):
for instance, url in self.urls.items():
try:
response = urllib2.urlopen(url)
except urllib2.HTTPError, e:
collectd.error(str(e))
except urllib2.URLError, e:
collectd.error(str(e))
else:
data = response.read()
m = self.pattern.findall(data)
for key, value in m:
metric = collectd.Values()
metric.plugin = 'nginx-%s' % instance
metric.type_instance = key.lower()
metric.type = 'nginx_connections'
metric.values = [value]
metric.dispatch()
requests = data.split('\n')[2].split()[-1]
collectd.debug('Requests %s' % requests)
metric = collectd.Values()
metric.plugin = 'nginx-%s' % instance
metric.type = 'nginx_requests'
metric.values = [requests]
metric.dispatch()
def config(self, obj):
self.urls = dict((node.key, node.values[0]) for node in obj.children)
nginx = Nginx()
collectd.register_config(nginx.config)
collectd.register_read(nginx.do_nginx_status)
struct curl_slist *curl_list = NULL;
curl_list = curl_slist_append(curl_list, header);
curl_easy_setopt(curl, CURLOPT_HTTPHEADER, curl_list);
I have written a sample KMDF driver. I dont know if I did every thing right but have seen KMDF driver printing Debug message in DebugView utility - when I added this driver as new hardware. It also showed up as "Sample Device" under device manager.
Now I want to write a sample client that could call this Driver - so I can establish a connection between driver and client. I read that we need to use 'CreateFile' and 'DEviceIOControl' etc. But I am not able to get a start on it.
Can you please guide me around creating sample client to access the sample KMDF driver ?
My INF file for the driver looks like this :-

There are many relevant samples in the WDK. For example, take a look at KMDF Echo sample.
First you will need to name your object.
Second you will need to do at least one of the following:
Create a Symbolic link in the \GLOBAL??\
Register a Device Interface.
Option 1 will let you do the simple
CreateFile("\\\\.\\<device_name>, ...);
Option 2 and you will need to use the Setup DI Api routines to find your device to open it.
I have a very large trace file and am trying to use Wireshark to determine which dest port has the most packets sent to it. Is there a way to get counts of packets sent to particular ports? Or to sort by number of packets sent a port?
You can write a simple wireshark listener in lua.
local tap
local ports = {}
local function packet(pinfo, tvb, userdata)
-- store number of packets per each port
local port = pinfo.dst_port
ports[port] = (ports[port] or 0) + 1
end
local function draw(userdata)
local maxi,maxv = 0,0
-- print all gathered statictics and find max
for i,v in pairs(ports) do
print(i .. ":", v)
if maxv < v then
maxi,maxv = i,v
end
end
print ("Max:", maxi, maxv)
end
local function reset(userdata)
ports = {}
end
local function show_ports()
tap = Listener.new()
tap.packet = packet
tap.draw = draw
tap.reset = reset
end
register_stat_cmd_arg('ports', show_ports)
Try it:
tshark -X lua_script:ports.lua -z ports -r in.pcap
I'm trying to send data via UDP to the network. I've got some PHP code running on my local machine which works:
#!/usr/bin/php -q
<?php
$socket = stream_socket_client('udp://225.0.0.0:50000');
for($i=0;$i<strlen($argv[1]);$i++) $b.="\0\0\0".$argv[1][$i];
fwrite($socket,$b,strlen($argv[1])*4);
fclose($socket);
?>
Gives me the output in tcpdump:
18:53:24.504447 IP 10.0.1.2.52919 > 225.0.0.0.50000: UDP, length 36
I'm trying to get to the same result on a remote iOS with the following code:
- (void)broadcast:(NSString *)dx {
NSData* data=[dx dataUsingEncoding:NSUTF8StringEncoding];
NSLog(#"Broadcasting data: %#", dx);
int fd = socket(PF_INET, SOCK_DGRAM, IPPROTO_UDP);
struct sockaddr_in addr4client;
memset(&addr4client, 0, sizeof(addr4client));
addr4client.sin_len = sizeof(addr4client);
addr4client.sin_family = AF_INET;
addr4client.sin_port = htons(PORT);
addr4client.sin_addr.s_addr = htonl(INADDR_BROADCAST);
int yes = 1;
if (setsockopt(fd, SOL_SOCKET, SO_BROADCAST, (void *)&yes, sizeof(yes)) == -1) {
NSLog([NSString stringWithFormat:#"Failure to set broadcast! : %d", errno]);
}
char *toSend = (char *)[data bytes];
if (sendto(fd, toSend, [data length], 0, (struct sockaddr *)&addr4client, sizeof(addr4client)) == -1) {
NSLog([NSString stringWithFormat:#"Failure to send! : %d", errno]);
}
close(fd);
}
Which gives me the following output in tcpdump:
19:01:22.776192 IP 10.0.1.4.60643 > broadcasthost.50000: UDP, length 9
Looks basically OK, but doesn't arrive in Quartz Composer for some reason, I guess there should be the IP address or something instead of 'broadcasthost'.
Any idea?
The problem was not in the implementation of the broadcaster, but the format of the string. To work with Quartz Composer, every character needs to be preceded by a backslash-zero combination: "\0\0\0", so "abc" has to be formatted and sent as "\0\0\0a\0\0\0b\0\0\0c".
See also Celso Martinho's blog article: Leopard’s Quartz Composer and Network events.
I suggest using AsyncSocket ( google it, its on googlecode ), very well tested objective-c code that runs on iOS.
That way you can send data really easy using a NSData object. AsyncSocket manages the hard part for you.
If that isn't an option for you you should use CFSocket. What you are doing is implementing code that has been written for you already, CFSocket.
