sudo apt-get update
sudo apt-get install samba samba-client samba-common samba-common-bin smbfs winbind

Configure Samba to run automatically on boot
sudo update-rc.d smbd defaults
sudo update-rc.d nmbd defaults
 
Make a backup copy of smb.conf
sudo cp /etc/samba/smb.conf /etc/samba/smb.conf.orig 
Edit smb.conf file and replace the entire contents by below copy of a generic config for a kickstart
sudo vi /etc/samba/smb.conf

[global]
workgroup = WORKGROUP
netbios name = ServerHostname
server string = ServerName Share %v
security = user
;guest account = nobody
; logs in /var/log/samba/
log level = 3

[media]
comment = Multimedia User Directory
path = /home/media
browsable = yes
guest ok = yes
read only = yes
create mask = 755
available = yes
public = yes
writeable = no

[root]
comment = System Root
path = /
browsable = yes
guest ok = no
read only = no
create mask = 755

Create a samba account for your unix user, note that you can use same username but must create the account in samba to be able to connect to share. Unix user account are not able to connect to Samba shares without this account.
username@server:/etc/samba$ sudo smbpasswd -a username
New SMB password:
Retype new SMB password:
username@server:/etc/samba$ sudo pdbedit -w -L
nobody:65534:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX:[U          ]:LCT-00000000:
username:1000:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX:48BEDDCF584A04818385511BE563518B:[U          ]:LCT-4E694203:

Copy files and folders using SCP with spaces in path

Copying data from one system to other with file or folder names that contain spaces in path can be achieved using this guide. In this case I am copying data from Macbook to Windows 10 computer. In order to copy the data easily it is better to use bash commands. Windows computer can support WSL (Windows subsystem for Linux) and you can run one of few linux distributions to use shell commands. I have Ubuntu set up within my Windows 10 using WSL. If you do not have WSL, you can set it up using my guide here . The copy can be performed in two ways: 1) Using SCP Source (MacOs) path: /home/Users/username/Documents/data extract from 2020/ First of all you add escape sequence to the path so it will become:  /home/Users/me/Documents/data\ extract\ from\ 2020/ . While this works on local system for SCP you'll have to double the escape sequences by replacing \ with \\, as below. Figure out your source computer IP address using "ifconfig" command. Now using scp command on target syst...

VMWare ESXi 6.5 HP Custom Image Upgrade to v6.5U3

I had been escaping the Unhandled Exception error every time I log into my ESXi standalone server running v6.5 on N54L and can't be upgraded to v6.7 due to process compatibility. I have finally found the HP Custom image updated to v6.5U3 which appeared to have the fix built into it. It was quite straightforward update using the l latest 6.5 HP image so as habit I am making notes here for myself and everyone else who may find it useful. First of all I downloaded HP Custom v6.5U3 image  by selecting Offline Bundle. I then placed it in my datastore e.g. ds001. Once copied I ran following command line after I was connected to ESXi using ssh. # esxcli software vib update -d /vmfs/volumes/ds001/VMware-ESXi-6.5.0-Update3-14990892-HPE-preGen9-650.U3.9.6.10.1-Dec2019-depot.zip This command took few seconds or may be minutes but confirmed that updates have been installed and will take effect after reboot. So I rebooted the host and it worked like magic. # reboot I did not place host in main...
