Linux Mint: How to unblock wifi from hardblock and softblock

Today, my 15 month old son pressed bunch of keypad buttons very quickly before I stopping him to do his experimentation on the Linux terminal. By the way, he likes Linux terminal :-) ......

Long story short, I restarted the computer in the late evening and found my computer wifi is not working. Everything is OK but I could not turn on the wifi.

Then I ran the following command in the terminal:

sudo rfkill list

 On the terminal, I have got the following response, after executing the above command:

0: phy0: Wireless LAN
Soft blocked: no

Hard blocked: yes

Hard blocked means, the wifi is turned-off by the physical switch. In my Dell machine, it is the F2 key. So I turned-on. Now, I have ran the command again:

sudo rfkill list

On the terminal, I have got the following response, after executing the above command:

0: phy0: Wireless LAN
Soft blocked: yes
Hard blocked: no
5: hci0: Bluetooth
Soft blocked: no
Hard blocked: no

To turn off the soft block, I ran the following command and my wifi alive again:

sudo rfkill unblock all

To verify, I ran the sudo rfkill list command again and I got the following response on the terminal:

0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
5: hci0: Bluetooth
Soft blocked: no
Hard blocked: no


So my wifi is not blocked now.

There is a process already using the admin port 4848 -- it probably is another instance of a GlassFish server; ERROR

After long time later, I am writing my programming blog again. Today, I downloaded glassfish-3.1.2.2-unix.sh. I am running Fedora 16. After successful installation of the glassfish, I was getting error when I ran the the following command: asadmin>start-domain "There is a process already using the admin port 4848 -- it probably is another instance of a GlassFish server. Command start-domain failed." Then I checked my hostname of the machine: hostname I got my hostname is nix-domain Now, nix-domain is not listed in the /etc/hosts file. Therefore, I added nix-domain in the file. 127.0.0.1               localhost nix-domain Now, I tried to run the start-domain again. It started perfectly without any error. Therefore, I understood that my machine assigned hostname 'nix-domain' is not listed in the hosts file, glassfish generated the error. I am hoping, it is not only the solution, there must be...

WildFly 19 and Log4J2

In this post, I would like to share my story about external configuration file of Log4J2. I developed a Java web application in WildFly 19 application server. It was my pet project. I followed few strict rules about 3rd party libraries. For example, I did not use log4j2-web library/jar file. It was the challenge because in some workplace you cannot have luxury to get all bells and whistle. You have to accept the situation. Therefore, I took this challenge to use external configuration file of Log4J2 in the web application without depending on log4j2-web jar file. My development environment's logging configuration is not same as production environment. In this case, I do not want to swap between development configuration and production configuration file during deployment.    The above situation can be mitigate by two ways: Use external logging configuration file. User application server specific logging system. For exampke, ...
