During the FastSync, DL around  80 Mbps, besides this, during the normal initial sync DL around 8 Mbps every several seconds.


Daily normal traffic 3GB, 66% UL, 33% DL

Check if port 44158 is open: 

 

C:\>curl ifconfig.co/port/44158
{
  "ip": "86.121.x.y",
  "port": 44158,

Bobcat Uplink (green) 4-6 Mbps vs Downlink (red) 1-3Mbps, traffic done every ~~ 50 +/- seconds


Bobcat after 48 Hours, stock antenna, changing from 25 to 45 witnesses in last 24 hours. 1.14 HNT/24h.

Traffic done after the initial synchronization : around 3.5GB/day so around 105 GB/month


After an Internet 10 minutes short outage, the UL/DL traffic catches up very slow - 2-3 hours. What is the mining impact?



Diagnostic report over Bluetooth

If the IP starts with 172.17.x.x, it is the Internal Docket container IP, not the one provided by the local network, you can ignore it.

How to find the Bobcat IP ?

1. Easiest way: Install Android app: Angry Port Scanner , scan for port 44158


2. other methods:


  1. Look in the router
  2. From Diagnostic Report window

 

  1. Nslookup bobcatminer

 

C:\nslookup bobcatminer

Server:  router.asus.com

Address:  192.168.x.y

 

Name:    bobcatminer

Address:  192.168.z.v

 

 

  1. In Windows, you can do this with:

for /l %i in (1,1,254) do ping -n 1 -w 50 192.168.0.%i

Basically, you are running ping in a 'for' loop. The arguments are thus:

  • /l -- causes 'for' to loop
  • %i -- incrementing variable
  • (start, increment, end) -- the start, increment, and ending values
  • -n -- number of packets to send
  • -w -- time in milliseconds to wait for a reply

After that completes, you can review the ARP table with

arp -a

1 DC = 24 Byte Packet = $0.00001 USD (Credit Card purchases: minimum $10) 


112 DC =  0.00112 USD  - spent by the Sensor Owner ?


0.000059 HNT x 20 USD = 0.00111746 - received by the Hotspot Owner

the same figures?
