- raspbian 3 GUI with static ip 192.168.0.199
- and a DELL server running headless ubuntu 192.168.0.196
- and a RFID reader running on 192.168.0.68
All are static IP addresses
I have a python script that polls a RFID reader running on 192.168.0.68 and has pretty consistent connection. Once the python script polls and has a positive update, it will attempt to update the DELL server provided that the RFID request is not repeated for at least 5 seconds. This is to reduce too many requests sent to the server.
However, what happens is that there are intermittent loss of connection between the raspberry pi 3 and the DELL server.
The dell server also serves web pages.
When the loss of connection happens, I can still access the dell server web pages from other devices in the same network. Similarly, from the raspberry pi 3, I can also access other servers' web pages.
This is a client network setup so I don't really have much control though I can talk with the network admin.
He is sure there's no throttling involved.
However, the connection between the raspberry pi 3 and the DELL server can be intermittent sometimes.
While I am comfortable with server side scripting and linux in general, I am at a loss of how to narrow down the issue.
The network admin at the client site is now casting aspersions on the raspberry pi 3 which is newly bought.
I am unsure if that's the case.
How to narrow down the issue or replicate the problem?
All devices are running on LAN cable.
