Website spying my address using WebRTC - what can they see? - webrtc

Website I'm using connects from javascript to external WebRTC server to get information about me. They are getting response like this and sending selected information to their server.

Can anybody point me to a documentation or explain what information is encoded in address: "[edd1:73ea:ef2e:73eb:f08b:73ec:4f62:4888]" and what they can find out about me? It looks like IPv6 address but it is not.
Thanks


That section in the candidate line holds an IPv4 or IPv6 address. The address follows the priority 1677732095. Here are a few resources with detailed documentation:

In most cases, it means there are some issues with connecting to stun/turn server from your device. Either the host is unreachable via udp or there are issues with authentication.
The easiest way to test it is with trickle-ice page from your device's browser. Set address and creds of your stun/turn and check if there are some relay/srflx/prflx candidates.
If so, then it's a configuration issue on gstreamer-side.
If not, then try using tcpdump and inspect stun requests/responses. Maybe you're not getting the responses, or there are some error responses which might give you an idea of what's wrong.

Adding SASL Authentication in Kafka Banzai

I am looking to add SASL Plaintext authentication in Banzai Kafka. I have added following configs in my read only config section.
readOnlyConfig: |
auto.create.topics.enable=false
cruise.control.metrics.topic.auto.create=true
cruise.control.metrics.topic.num.partitions=1
cruise.control.metrics.topic.replication.factor=2

listener.name.external.scram-sha-256.sasl.jaas.config=org.apache.kafka.common.security.scram.ScramLoginModule required username="user" password="testuser";
I have scripted following in listener config
listenersConfig:
externalListeners:
- type: "sasl_plaintext"
name: "external"
externalStartingPort: 51985
containerPort: 29094
accessMethod: LoadBalancer
internalListeners:

containerPort: 29092
usedForInnerBrokerCommunication: true
- type: "plaintext"
name: "controller"
containerPort: 29093
usedForInnerBrokerCommunication: false
usedForControllerCommunication: true
When I try to connect producer or consumer - kafka returns Authentication Authorization failed error.
I am setting following properties:
session.timeout.ms=60000
partition.assignment.strategy=org.apache.kafka.clients.consumer.StickyAssignor
security.protocol=SASL_PLAINTEXT
sasl.mechanism=SCRAM-SHA-256
sasl.jaas.config=org.apache.kafka.common.security.scram.ScramLoginModule required username="user" password="testuser";
Can any one suggest on this?

How to fix "errno":"ENOTFOUND" error in smtp configuration using express js

I am trying to configure node mailer in express js application. During the time of sending mail, I got an error ENOTFOUND.
My smpt configurations are,
smtpServer: {
host: "smtp.gmail.com",
port: 587,
secure: false,
user: "email#gmail.com",
pass: "password",
fromName: "",
fromAddress: ""
}
Error :
{"errno":"ENOTFOUND","code":"ECONNECTION","syscall":"getaddrinfo","hostname":"smtp.gmail.com","host":"smtp.gmail.com","port":587,"command":"CONN","meta":{"errno":"ENOTFOUND","code":"ECONNECTION","syscall":"getaddrinfo","hostname":"smtp.gmail.com","host":"smtp.gmail.com","port":587,"command":"CONN"}}
I suspect this error came because of proxy issues. So, I checked the smpt hostname in my machine nslookup table.
That is returned following result:
$ nslookup smtp.gmail.com
Server: 127.0.1.1
Address: 127.0.1.1#53
Non-authoritative answer:
*** Can't find smtp.gmail.com: No answer
Other than else what I missed here?

How to test RDP port is up using Prometheus Blackbox

I have been struggling to implement an RDP probe to check multiple ports in Windows machines using Prometheus Blackbox.
So far I manage to check DNS, ping, ports 80,8080 but I cannot manage to test 3389!
As a rule of thumb I would like to be able to ping/probe any ports that have services running on this hosts
My blackbox.yml is:
modules:
http_2xx:
prober: http
http:
http_get_2xx:
prober: http
http:
method: GET
http_post_2xx:
prober: http
timeout: 5s
http:
method: POST
headers:
Content-Type: application/json
body: '{}'
tcp_connect:
prober: tcp
pop3s_banner:
prober: tcp
tcp:
query_response:
- expect: "^+OK"
tls: true
tls_config:
insecure_skip_verify: false
ssh_banner:
prober: tcp
tcp:
query_response:
- expect: "^SSH-2.0-"
irc_banner:
prober: tcp
tcp:
query_response:
- send: "NICK prober"
- send: "USER prober prober prober :prober"
- expect: "PING :([^ ]+)"
send: "PONG ${1}"
- expect: "^:[^ ]+ 001"
icmp:
prober: icmp
dns_test:
prober: dns
timeout: 5s
dns:
query_name: google.com
preferred_ip_protocol: ip4
And my prometheus.yml 3389 port probe entry is:
- job_name: "rdp-dev-status"
metrics_path: /probe
params:
module: [dns_test]
static_configs:
- targets:
- nostradata-dvmh-prodweb-01
# file_sd_configs:
# - files:
# - /opt/prometheus/tools/targets/rdp-dev-targets.yml
relabel_configs:
# Ensure port is 22, pass as URL parameter
- source_labels: [__address__]
regex: (.*)(:.*)?
replacement: ${1}:3389
target_label: __param_target
# Make instance label the target
- source_labels: [__param_target]
target_label: instance
# Actually talk to the blackbox exporter though
- target_label: __address__
replacement: PROD-NIFI:9115

module: [dns_test]
Using a DNS probe is probably not going to work with RDP. Try the tcp_connect module.

Kurento Hello World Stuck after receiving candidates

I am trying to setup a Kurento media server behind an nginx proxy & testing with the Kurento-hello-world example. The TURN server is in place & Kurento is up.
I added the TURN url in file /etc/kurento/modules/kurento/WebRtcEndpoint.conf.ini as explained here
turnURL=kurento:kurento#193.147.XXX.XXX:3478
I opened the specified ports :
3478 TCP & UDP
49152-65535 UDP
EDIT : I notice TURN is announcing a remote HEAD IP that seems to be in my network, but is not linked to my project and never specified in configs, as seen in the browser console, I receive a candidate 2 with the unknown external IP and a candidate 3 with good external IP but wonder if the browser can be stocked trying to connect to a bad one. Is it possible to avoid TURN propose a specific address ?
Locally, I can see (netstat -tulpn) the candidates UDP ports allocted on both kurento & TURN machines. The video input that should come from the server never appears, meaning the Connection is never achieved ?
