get linux boxes to show hostname on windows network

http://www.terminally-incoherent.com/blog/2007/10/03/access-linux-workstation-by-hostname-on-a-windows-network/

Once it is installed and running, edit /etc/samba/smb.conf and put following lines in somewhere in Global Settings section:

workgroup = your_workgtoup netbios name = your_hostname

I was wondering why there was not an even amount of ram reported on linux.

Graphics is on the motherboard so it uses some memory.

Ran this:

dmesg | grep "Memory"

[    0.000000] Memory: 16069952K/16453324K available (8427K kernel code, 1285K rwdata, 3956K rodata, 1480K init, 1292K bss, 383372K reserved, 0K cma-reserved)
[    0.871218] [drm] Memory usable by graphics device = 2048M

cat /proc/meminfo

dd command for two discs with different size partitions

Now to restore the image to any sdb:

Next, backup entries of the extended partitions:

Use 446 bytes to overwrite or restore your /dev/XYZ MBR boot code only with the contents of $mbr.backup.file.

Use 512 bytes to overwrite or restore your /dev/XYZ the full MBR (which contains both boot code and the drive's partition table) with the contents of $mbr.backup.file.

sfdisk Command

The sfdisk command act as a partition table manipulator for Linux. You can use this tool to list partitions too:

Sample outputs:

71669760
Disk /dev/sda: 8922 cylinders, 255 heads, 63 sectors/track
Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0
   Device Boot Start     End   #cyls    #blocks   Id  System
/dev/sda1   *      0+    104-    105-    838656   83  Linux
/dev/sda2        104+    235-    131-   1048576   82  Linux swap / Solaris
/dev/sda3        235+   8922-   8688-  69781504   83  Linux
/dev/sda4          0       -       0          0    0  Empty

Where,

-l : List the partitions of a device.

-s : List the size of a partition.

-u or -uS or -uB or -uC or -uM : Accept or report in units of sectors (blocks, cylinders, megabytes, respecpively). The default is cylinders, at least when the geometry is known.

added these lines to apache directive for

AddEncoding gzip gz 
<FilesMatch "\.gz$">
      ForceType text/plain
      Header set Content-Encoding: gzip
</FilesMatch>

From the X11 app, open the terminal, and then access the remote host with:

  ssh -XC user@host

Then, when logged, simply run the command for the desired app, ex: firefox, nautilus, thunderbird, whatever…

You can even launch only the system (Ubuntu, Xubuntu, Mint, etc..) Main Menu, and interact with the remote system from there, without the need of a full graphical front-end. On a remote Linux Mint env, i simply run:

  mintmenu&

If you really need it, you can even start the remote graphical environment locally at your Mac's X11, simply running:

  ubuntu-session
  xubuntu-session
  etc... (depends of your remote environment)

Better than any VNC, even better than an X11VNC connection! Secured and compressed connection FTW.

try reloading grub on nvme drive from grub manual

This install doesn’t conflict with standard install as long as they are in separate directories.

Note that grub-install is actually just a shell script and the real task is done by other tools such as grub-mkimage. Therefore, you may run those commands directly to install GRUB, without using grub-install. Don’t do that, however, unless you are very familiar with the internals of GRUB. Installing a boot loader on a running OS may be extremely dangerous.

On EFI systems for fixed disk install you have to mount EFI System Partition. If you mount it at /boot/efi then you don’t need any special arguments:

# grub-install
Otherwise you need to specify where your EFI System partition is mounted:

# grub-install --efi-directory=/mnt/efi

Bios keeps hanging and I am reloading it via a usb thumb drive and the button on the back

I am going to try a different bios next time. Notes about bios versions. These are on flatboy as well in case I can't get to them because trackfile hangs at the splash screen.

Using 2704 now but 2304 has been renamed so should get picked up next time. 5-11-18
