Ich habe eines zum Aufbau von SSH Tunneln, welches ich regelmässig nutze. Achtung "KnownHost" muss dazu unverschlüsselt seien.

Code: Alles auswählen

#!/bin/bash

# Function to display a list of known hosts
show_known_hosts() {
  cut -f 1 -d ' ' <~/.ssh/known_hosts | sed -e 's/,.*//g' | uniq | grep -v "\[" | tr ' ' '\n' | grep -v "=" | sort
}

# Function to prompt for yes/no answers
ask_yes_no() {
  local prompt="$1 (yes/no): "
  read -p "$prompt" response
  case "$response" in
    [YyJj]) return 0 ;; # Yes
    [Nn]) return 1 ;;   # No
    *) ask_yes_no "$prompt" ;; # Repeat prompt if the answer is not valid
  esac
}

# Display the list of known hosts if the user chooses to
if ask_yes_no "Do you want to display the list of known hosts?"; then
  show_known_hosts
fi

# Read connection details
read -p "Server hostname or IP address: " Server
read -p "Username: " User
read -p "Remote server source port: " sPort
read -p "Local port on your computer: " lPort

# Set up SSH tunnel and display message
if ssh -L ${lPort}:${Server}:${sPort} -D 1083 -p 1081 ${User}@localhost \
  "while true; do echo -e \"Tunnel to ${Server}, local port ${lPort}\"; sleep 15; done"
then
  echo "The SSH tunnel has been successfully established."
else
  echo "ERROR: The SSH tunnel could not be established."
fi

ein weiteres zum auslesen, der Gültigkeit von Zertifikaten die übers System verteilt sind.

Ein weiteres für das automatische verschlüsselte Backups, beim Anschluss bestimmter USB Platten. Voraussetzung hier, Luks verschlüsselte USB Platten, die UDEV bekannt, sind so dass das Script beim Anschluss dieser automatisch Startet. Das Script Mountet dann die USB Platten, Entschlüsselt diese und Startet dann ein Backupscript. Das Backupscript wiederrum kann dann ein einzelnes Backup Starten oder wenn mehrere USB Platten angeschlossen wurden, die bekannt sind, diese dann automatisch synchronisieren.

Load- und temperaturabhängige CPU-Frequenzsteuerung

Ich habe mir hier mal ein Script geschrieben, das die CPU-Frequenz herunterregelt, wenn die Temperatur zu hoch ist. Solche Programme gibt es Einige. Ich habe mir das geschrieben, weil ich die Drosselung gerne nur dann hätte, wenn die CPU-Load ausreichend niedrig ist. D. h. die Überschreitung der Maximaltemperatur ist bei hoher Load für mich akzeptabel. Ich nehme dabei auch immer den höchsten Load-Wert aus dem Tripel 1/5/15-Minuten Load, damit sowohl auf kurzfristige Laststeigerungen schnell reagiert wird, als auch bei nur kurzfristigen Lastabfällen nicht sofort die Frequenz wieder herunter gedreht wird. Ich möchte also eine möglichst geringe Beeinträchtigung der Performance des Servers.

Ansonsten wird bei großen Unter- oder Überschreitungen der Temperatur mit größeren Frequenzsprüngen reagiert, um eine schnellere Wirkung zu erzielen. Mir ist im Übrigen auch klar, dass die CPU-Auslastung nicht der einzige Auslöser für eine hohe Load ist. Auch die Entscheidung einfach von allen Temperatursensoren immer den höchsten Temperaturwert zu nehmen, trifft üblicherweise auf den Prozessor-Sensor zu, muss es aber nicht unbedingt. Das ist nicht perfekt, passt aber für den vorliegenden Anwendungsfall.

Ein Gedanke, den ich am Anfang hatte, war noch der, ob das so gut ist, ständig an den Frequenzlimits rum zu drehen. Nachdem sich die aktuellen Taktfrequenzen der CPU-Cores aber sowieso ständig ändern (governor powersave), scheint mir dieses Bedenken unbegründet.

Auch scheint das Anliegen insgesamt widersprüchlich: Die Temperatur geht hoch, wenn die CPU-Last hoch geht und wenn die CPU Last hat, dann wird sie auch gebraucht. Da ergibt es ja keinen Sinn, gleichzeitig die Geschwindigkeit runter zu drehen. Faktisch bringt es aber doch etwas.

So wirkt sich dass dann im Betrieb aus:

Ich bekomme da eine Fehlermeldung bei dem CPU Script

Code: Alles auswählen

./test
<internal:/usr/lib/ruby/vendor_ruby/rubygems/core_ext/kernel_require.rb>:85:in `require': cannot load such file -- sys-cpu (LoadError)
	from <internal:/usr/lib/ruby/vendor_ruby/rubygems/core_ext/kernel_require.rb>:85:in `require'
	from ./test:31:in `<main>'

Im Head des Scriptes stehen ein paar Installationsanweisungen. Es müssen Ruby-Module installiert werden:

Code: Alles auswählen

# gem install sys-cpu awesome_print find

cpufrequtils müssen auch installiert sein.

1+ für den Thread!

Ich hatte mal vor Jahren einen Rechte Gau. Das damals verwendete Backup hatte beim Restore die Rechte der Dateien versaut.
Ich war selber schuld, weil ich halt direkt zurück gesichert hatte.
Deshalb läuft auf dem Server nun das hier:

Code: Alles auswählen

#!/bin/bash
#dateirechte.sh
DATUM=$(date +%d-%m-%Y)

nice getfacl -R -n / >/home/backup/dateirechte-$DATUM.txt
 
# wieder herstellen mit
#setfacl --restore=dateirechte.txt

Die Datei dateirechte.txt wird täglich mitgesichert und hilft versehentliche Änderungen zu reparieren
Ausserdem bei evtl. forensichen Vorfällen

Das ist gar nicht so verkehrt - mir ist auch schon mal aus versehen ein chown -R root:root / durchgelaufen - war nicht so der dolle . Zum Glück hatte ich noch ein REAR image. Schön wäre die Möglichkeit Pfade auszulassen. Mein 20 TB Archiv hat nur eine Rechte/Zugriffs Konfiguration.

Danke, läuft immer noch und hat mit der Zeit schon ein paar mal geholfen.

Pakete sind installiert, Ruby Pakete zu cpufrequtils

Ich wiederhole das nochmal: Die folgende Zeile, die im Skript steht und die ich in meinem letzten Beitrag schrieb, muss als root ausgeführt werden:

Code: Alles auswählen

gem install sys-cpu awesome_print find

Das sind drei Module, die ich im Skript einbinde. Die müssen da sein.

[speefak]

Dokus in Scripten lese ich als erstes hab's als root und User probiert. Werd's die Tage nochmal inner frischen D12 VM probieren.

Was ist bei Dir die Ausgabe von:

Code: Alles auswählen

gem install sys-cpu awesome_print find

Die Fehlermeldung von Dir bedeutet, dass das Modul nicht geladen werden könnte, weil nicht gefunden.

[speefak]

Code: Alles auswählen

sudo gem install sys-cpu awesome_print find
