Supervisor 2024.08.0
Operating System 12.4

HA-Integration: Bosch custom component v0.26.1

It was a hard time to find the right Grafana-settings to get the water-temperature presented.
Bosch/Home-Assistant transports this value based on the state-series:

Hence Grafana needs a statement as shown:

iPad Samba file transfer fails

To be able to copy files over from iPad to Samba-shares the enhanced compatibility with Apple SMB clients and interoperability with Netatalk 3 AFP fileserver must be enabled.

Vfs-module is typically missing if you see in tshark messages like:

310 Create Response, Error: STATUS_OBJECT_NAME_INVALID;Read Response, Error: STATUS_OBJECT_NAME_INVALID;Close Response, Error: STATUS_OBJECT_NAME_INVALID

To get this fixed add to the [global] section in /etc/samba/smb.conf the following command:

vfs objects = fruit streams_xattr

The package samba-vfs-modules must be installed prior restarting the smb service.
Check if the package is installed with commands like:

ubuntu: dpkg -l samba-vfs-modules
RHEL. : rpm -qa | grep  samba-vfs-modules
etc.

a positive output looks similar to:
root@raspi24:/home/ugu5ma# dpkg -l samba-vfs-modules

ii  samba-vfs-modules:arm64 2:4.15.13+dfsg-0ubuntu1.5

If the package is missing add it with:

ubuntu: apt install samba-vfs-modules
RHEL. : yum install samba-vfs-modules
etc.

Restart Samba:

systemctl restart smbd

Done!

remove/rename files with spaces in filename(s)

Let’s examine the folder structure:

Search for files with space(s) in the filename(s)

To do a search within the current folder for all files with a space in the filename do:

find . -maxdepth 1 -type f -name "* *" | while read file; do ls -la   "$file"; done |more
-rw-r--r--  1 ugu5ma  staff  8 Dec 29 14:38 ./file 2.txt
-rw-r--r--  1 ugu5ma  staff  13 Dec 29 14:38 ./file 3.txt
-rw-r--r--  1 ugu5ma  staff  6 Dec 29 14:38 ./file 1.txt

the “-maxdepth 1” parameter limits the search within the current folder.
“-maxdepth 2” would search within the current and the first subfolder(s)

To do a recursive search for all files with a space in the filename do:

find . -type f -name "* *" | while read file; do ls -la   "$file"; done |more
-rw-r--r--  1 ugu5ma  staff  8 Dec 29 14:38 ./file 2.txt
-rw-r--r--  1 ugu5ma  staff  13 Dec 29 14:38 ./file 3.txt
-rw-r--r--  1 ugu5ma  staff  6 Dec 29 14:38 ./file 1.txt
-rw-r--r--  1 ugu5ma  staff  8 Dec 29 14:38 ./1/subfolder/file 2.txt
-rw-r--r--  1 ugu5ma  staff  13 Dec 29 14:38 ./1/subfolder/file 3.txt
-rw-r--r--  1 ugu5ma  staff  6 Dec 29 14:38 ./1/subfolder/file 1.txt
-rw-r--r--  1 ugu5ma  staff  8 Dec 29 14:38 ./1/file 2.txt
-rw-r--r--  1 ugu5ma  staff  13 Dec 29 14:38 ./1/file 3.txt
-rw-r--r--  1 ugu5ma  staff  6 Dec 29 14:38 ./1/file 1.txt
-rw-r--r--  1 ugu5ma  staff  8 Dec 29 14:38 ./3/file 2.txt
-rw-r--r--  1 ugu5ma  staff  13 Dec 29 14:38 ./3/file 3.txt
-rw-r--r--  1 ugu5ma  staff  6 Dec 29 14:38 ./3/file 1.txt
-rw-r--r--  1 ugu5ma  staff  8 Dec 29 14:38 ./2/file 2.txt
-rw-r--r--  1 ugu5ma  staff  13 Dec 29 14:38 ./2/file 3.txt
-rw-r--r--  1 ugu5ma  staff  6 Dec 29 14:38 ./2/file 1.txt

Rename files with space(s) in filename(s)

To replace the space with an underscore for files within the current folder execute:

find . -maxdepth 1 -type f -name "* *" | while read file; do mv "$file" ${file// /_}; done

➜  ordner ls -l
total 24
drwxr-xr-x  6 ugu5ma  staff  192 Dec 29 14:51 1
drwxr-xr-x  5 ugu5ma  staff  160 Dec 29 14:39 2
drwxr-xr-x  5 ugu5ma  staff  160 Dec 29 14:39 3
-rw-r--r--  1 ugu5ma  staff    6 Dec 29 14:38 file_1.txt
-rw-r--r--  1 ugu5ma  staff    8 Dec 29 14:38 file_2.txt
-rw-r--r--  1 ugu5ma  staff   13 Dec 29 14:38 file_3.txt

the files in the subfolders are still untouched:

ordner find . -type f -name "* *" | while read file; do ls -la   "$file"; done |more
-rw-r--r--  1 ugu5ma  staff  8 Dec 29 14:38 ./1/subfolder/file 2.txt
-rw-r--r--  1 ugu5ma  staff  13 Dec 29 14:38 ./1/subfolder/file 3.txt
-rw-r--r--  1 ugu5ma  staff  6 Dec 29 14:38 ./1/subfolder/file 1.txt
-rw-r--r--  1 ugu5ma  staff  8 Dec 29 14:38 ./1/file 2.txt
-rw-r--r--  1 ugu5ma  staff  13 Dec 29 14:38 ./1/file 3.txt
-rw-r--r--  1 ugu5ma  staff  6 Dec 29 14:38 ./1/file 1.txt
-rw-r--r--  1 ugu5ma  staff  8 Dec 29 14:38 ./3/file 2.txt
-rw-r--r--  1 ugu5ma  staff  13 Dec 29 14:38 ./3/file 3.txt
-rw-r--r--  1 ugu5ma  staff  6 Dec 29 14:38 ./3/file 1.txt
-rw-r--r--  1 ugu5ma  staff  8 Dec 29 14:38 ./2/file 2.txt
-rw-r--r--  1 ugu5ma  staff  13 Dec 29 14:38 ./2/file 3.txt
-rw-r--r--  1 ugu5ma  staff  6 Dec 29 14:38 ./2/file 1.txt

To replace the space with an underscore for files within the current folder and subfolders execute:

find . -type f -name "* *" | while read file; do mv "$file" ${file// /_}; done

Danger zone: delete files in current and subfolder with space(s) in filename(s)

find . -type f -name "* *" | while read file; do rm "$file"; done

Ubuntu: remove ipv4-protocol from ethernet interface

On my Ubuntu-host I have my ethernet-interface connected to an mirror-port.
I want to remove the ipv4-protocol from this interface to avoid unnecessary traffic on this interface.

With root-rights execute “nmcli connection show –active”:

ugu5ma nmcli connection show --active
NAME             UUID                                  TYPE      DEVICE          
Fleischele2      8877f4c8-b38d-4028-a71d-b237d8ff649e  wifi      wlp3s0          
br-5bece4d6fbd8  3a34eddc-2c98-4140-9b40-74bcd355cde4  bridge    br-5bece4d6fbd8

enp6s0           57bc44f6-5190-42b2-b17f-e928868a42c0  ethernet  enp6s0

my ethernet-interface (enp6s0) has UUID 57bc44f6-5190-42b2-b17f-e928868a42c0.

Let’s remove ipv4 :

ugu5ma nmcli connection modify 57bc44f6-5190-42b2-b17f-e928868a42c0 ipv4.method disabled

Check again:

➜  ugu5ma nmcli connection show --active                                                   
NAME         UUID                                  TYPE  DEVICE 
Fleischele2  8877f4c8-b38d-4028-a71d-b237d8ff649e  wifi  wlp3s0

done!
