No internet connection from Hyper-V VM with Dongle

Not many of us are using 3G/4G dongles these days, but I had to for some reason. I have a Windows 10 host and a Hyper-V VM Ubuntu guest OS.

Problem:

Having a connection issue from the guest OS when a dongle is used.
Each time I connect through the dongle, guest OS loses outside connectivity.
(It works fine if I use Wifi)

Fix:

In your windows machine, open Control Panel
Go to View network status and tasks

Click on Change adapter settings

Right-click on your dongle connection.

Select Properties in the right-click context menu

Go to Sharing tab

Check Allow other network users to connect through this computer's Internet connection

Use VEthernet (Default Switch) in the drop-down list (If your VM uses some other switch, use the proper connection)

Hit OK.

It should work now. If it still doesn't, disconnect and reconnect your VM's network connection from the VM itself.

Java, how to create a list with a single element

I wanted to create a Java List with a single element. Yet, I wanted to add more elements later. So, I was looking for a couple of ways to do this. So far there are multiple elegant ways to create a list with a single element with a one-liner. Not so much for a modifiable list though. Here's what I gathered so far. Followings are a few ways of creating a list with strictly a single entry. Can't add more elements. 1. Collections.singletonList() This returns an immutable list that cannot be modified or add more elements. // An immutable list containing only the specified object. List<String> oneEntryList = Collections. singletonList ( "one" ) ; oneEntryList.add( "two" ) ; // throws UnsupportedOperationException 2. Arrays.asList() This returns a fixed-size list consisting of the number of elements provided as arguments. The number of elements provided would be an array hence the size is fixed to the length of the array. // Returns a fixed-size list List...

Ubuntu DNS issue fix DNS_PROBE_FINISHED_BAD_CONFIG

Issue I've been playing with a VPN and somehow it messed up my DNS resolution configurations. Chrome gives DNS_PROBE_FINISHED_BAD_CONFIG error and can't ping google. So it seemed to be an issue with the DNS. Of course, restarting didn't fix it. I tried DNS lookup which gave me below. To make sure this is somehting to do with my DNS confgis, I ran the same by providing the google DNS servers. It works, which means my default DNS is not working for some reason. To make sure this, ran the below command. systemd-resolve --status Output has an entry for DNS Servers, which was ::1 Fix 1. Edit the file /etc/systemd/resolved.conf. sudo vi /etc/systemd/resolved.conf 2. Add new DNS entries. I added 2 google DNS and the cloudflare DNS sever. [Resolve] DNS=8.8.8.8 8.8.4.4 1.1.1.1 3. Restart the systemd-resolved and check the configuration is persisted in /run/systemd/resolve/resolv.conf file. sudo service systemd-resolved restart cat /run/systemd/resolve/resolv.co...
