How to configure a Raspberry Pi as a mobile hotspot using a UMTS dongle

Configuring a Raspberry as a UMTS concentrator for IoT

Browsing around I found the pieces of this solution, and I put them together in a guide.

I did not use the guide in the Raspberry site since I found it complicate to make it compatible with the mobile dongle, and I used instead the NetworkManager daemon, following many advices in that sense I found in technical blogs. The problem with this solution is that, as of now, it is incompatible with the native solution in the Raspian distribution, and so I removed some native network tools. This is relevant if you plan to alter the network configuraton of the Raspberry, but it is otherwise transparent.

The reason why I developed this solution is to have an autonomous IoT concentrator device; as succh, it does not provide Internet access to devices connected to the RPi through WiFi or wired Ethernet. In t

Configure Git to use a proxy

In Brief

You may need to configure a proxy server if you're having trouble cloning or fetching from a remote repository or getting an error like unable to access '...' Couldn't resolve host '...'.

Consider something like:

weakly-referenced object when connect to mysql in python
I came across this issue using the following code file
the error message is ReferenceError: weakly-referenced object no longer exists
reason is in the mysql/connector/cursor.py file
see these lines:

"""Set the connection"""
try:

/** The created agent jar file name */
protected static final AtomicReference<String> agentJar = new AtomicReference<String>(null);
