SSH Tunnel einrichten
Oft steht man hinter einer Firewall und nur manche Ports sind offen bzw. einige Seiten gesperrt. Desweiteren ist auch die Kommunikation dann gesichert wenn man sich in einem nicht vertrauten WLAN befindet (Hotel z.B.)
SSH Tunnel einrichten und aufbauen
SSH Server eingeben beim Host Name und bei Saved Sessions einen Namen für die Konfiguration aussuchen.
Irgendeinen Port aussuchen, Dynamic auswählen und mit Add hinzufügen.
anschließend Speichern und Verbindung öffnen
Nun steht der SSH Tunnel.
Firefox Tunneln
Bei Firefox ist die Einstellung sehr einfach. Die Screenshots sprechen für sich.
FTP über SSH Tunneln
Hierzu benötigt man einen FTP Client (z.B. WinSCP). Authentifizierung per SSH Schlüssel wird in einem anderen Beitrag erklärt.
SSH über SSH tunneln
Klingt bizarr, aber manchmal möchte man sich mit einem SSH Server verbinden der nicht über Port 22 erreichbar ist, und gleichzeitig ist jedoch genau dieser besagte Port von der Firewall gesperrt.
Auch hier ist es kein Hexenwerk. Vermutlich gibt es aber auch noch andere Möglichkeiten.
NAS4Free Status mit Zabbix
Es werden Plattenzustand / Temperatur und RAIDZF Pool Status ausgelesen.

Dies ist nur ein Grundgerüst. Für jede einzelne Platte kann / muß / sollten die Applications angepaßt oder erweitert werden. Ebenfalls zu bedenken, jeder Festplattenhersteller hat eine etwas andere SmartCTL Ausgabe.
So sieht’s dann aus:

Diese Lösung schien in manchen Fällen Probleme zu bereiten.
Folgender Weg funktioniert definitiv:
Entsprechenden Agent unter diesem Link herunter laden: http://repo.zabbix.com/zabbix/2.0/debian/pool/main/z/zabbix/
|
1 2 3 4 5 6 |
cd ~ mkdir zabbix cd zabbix wget http://repo.zabbix.com/zabbix/2.0/debian/pool/main/z/zabbix/zabbix-agent_2.0.6-2+wheezy_amd64.deb dpkg -i zabbix-agent_2.0.6-2+wheezy_amd64.deb nano /etc/zabbix/zabbix_agentd.conf |
Die üblichen Änderungen an der Agent Konfiguration können nun vorgenommen werden (Server IP / Log Verzeichnis / UserParameter usw.)
Der Agent wird mit
[code lang=”bash”]/etc/init.d/zabbix-agent restart[/code]
neu gestartet
Für die UserParameter fehlen noch z.B. die SmartMonTools.
Diese werden mit
|
1 |
apt-get install smartmontools |
nachinstalliert.
UserParameter Einstellungen befinden sich auf der Zabbix Konfigurationsseite.

Ramps 1.4 Heatbed MOSFET Austausch
Die Heatbed Heizung schaltete sich andauernd ab. Nach einer genaueren Überprüfung zeigte sich, daß der Q3 MOSFET am D8 Ausgang überhitzte.
WordPress Migration
Ich wollte den Blog umziehen da die Geschwindigkeit nicht berauschend war.
Quelle – hosted Domains bei 1und1 / Apache / mySQL
Ziel – root Server mit NGINX / mySQL und PHP5-FPM
Das meiste geht recht einfach.
Neues System einrichten (mit ISPConfig). NGINX Direktive anpassen.

Es mußte noch memcached installiert werden.
|
1 2 3 4 |
sudo apt-get install memcached sudo apt-get install php5-memcached sudo service nginx restart sudo service php5-fpm restart |
WP Caching mit dem WP-FFPC Plugin.
Hier läuft nun der memcached Treiber.
Export -> Import der Posts auch kein großes Problem mit den WordPress Tools.
Das einzig ärgerliche waren die Bilder. Diese werden nicht mit exportiert. Daher per FTP Transfer von dem einen Server auf den anderen. (wp-contentuploadsjahremonate)
Auf DB Ebene mußte ich nur noch die Links anpassen.

UPDATE `wp_buyenne`.`wp_posts` SET `post_content` = REPLACE(`post_content`, '10.0.1.84:81/', '10.0.1.84:81/') WHERE `post_content` LIKE '%blog.buyenne.com%' COLLATE utf8mb4_bin |
Et voila, es funktioniert.
Portalfräse – Unterbau
Für den Unterbau habe ich 45er Profil 10 schwer genommen.
- 4*1410 mm
- 4*900 mm
- 6*710 mm
- 2*720 mm
- Stellfüße / Winkel und die nötigen Schrauben.
- 10 mm MDF für Rück- und Seitenwände
- 15 mm Multiplex für die Böden und Deckplatten.
Zuerst wurden die 4 Eckpfeiler vorbereitet
3D Drucker – Delta Bauform – Bau
Den Delta Drucker in seiner ersten Form konnte ich mangels Portalfräse (vorerst) nicht bauen.
Die Lösung war doch recht einfach. Siehe technische Zeichnung.
