Updating java GUI components

I've had numerous problems over the years trying to update java components such as labels before carrying out other tasks and reaearch tells me that Threads are the way to do this.

Connect to Windows share from Linux command line.

An example of connecting to a Windows share from Linux command line;

smbclient //IP_ADDRESS/SHARE_NAME -U username

smbclient //192.168.254.198/public -U username

Then you will be promted for the password and find yourself at the smb: \> prompt.

You can then use;
ls for a listing of files
get filename to grab a file
cd folder to change directory
...etc

Revisited Aug 2024

The below is related to Slackware 15 and used the sbopkg method, see here for more information about getting sbopkg up and running.

So, I set about building Docker using the following order:

which is required to satisfy dependencies.

Once google-go-lang was installed, the build or runc failed and I found my way to the solution [here]. Essentially, you should build and install google-go-lang and then log out and back in before continuing with runc.

Once the above was done, or running the shell script at /etc/profile.d/go.sh then was good to continue (note, I done this using my current user, with and without sudo and also as root. I eventually had to open a new terminal to get it to work without error).

Once complete, do;

sudo groupadd -r docker

sudo usermod -a -G docker <username>

Note: 

then you need to install docker-cli which I chose to do using sbopkg thanks to Audrius Kažukauskas for this [https://slackbuilds.org/repository/15.0/system/docker/]

In hindslight, this should be added to the above packages order, after docker itself.

Change form GPT to MBR partition types

To change from GPT to MBR partitioning type under linux;

disk /dev/sda (assuming the drive is sda)

Then use the x option (extra functionality)

then use option z to destroy GPT

Now you can use cfdisk /dev/sda as per normal and choose DOS
