Apache2 startet täglich neu um 6:25 Uhr
02.03.2019 - Lesezeit: ~1 Minute

Apache2 startet täglich neu um 6:25 Uhr, was auf einem Rechner, der 24/7 läuft wenig Sinn macht. (Denn es gibt Leute, die zu dieser Zeit schon arbeiten.;-)

Deshalb habe ich den täglichen cron-job auf 2:25 Uhr umgestellt.

$ sudo nano /etc/crontab
# m h dom mon dow user  command
17 *    * * *   root    cd / && run-parts --report /etc/cron.hourly
25 2    * * *   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )
47 2    * * 7   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly )
52 2    1 * *   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly )
#
$ sudo service cron reload

Hintergrund

  • damit die Logdateien von Apache nicht zu groß werden werden diese mit Logrotate umbenannt und gepackt.
  • Logrotate stoppt deshalb den Apache bearbeitet die Logdateien und startet den Apache wieder 
    /etc/logrotate.conf
/etc/logrotate.d/apache2
  • Logrotate selbst wird vom cron.dayly aufgerufen 
    /etc/cron.daily/logrotate

Letsencrypt auf BBB erneuern
20.02.2019 - Lesezeit: 3 Minuten

Von Letsencrypt kommen E-Mails mit der Nachricht

You may need to update your client to the latest version in case it is still using the deprecated TLS-SNI-01 validation method. https://community.letsencrypt.org/t/february-13-2019-end-of-life-for-all-tls-sni-01-validation-support/74209

  • Neue Version von certbot 0.28 installieren

  • Mit dem neuen certbot das Zertifikat erneuern:

    $ certbot --version || /path/to/certbot-auto --version
certbot 0.28.0
$ sudo sh -c "sed -i.bak -e 's/^\(pref_challs.*\)tls-sni-01\(.*\)/\1http-01\2/g' /etc/letsencrypt/renewal/*; rm -f /etc/letsencrypt/renewal/*.bak"
$ sudo certbot renew --dry-run

  • Jetzt kommt die Fehlermeldung:

    IMPORTANT NOTES:
- The following errors were reported by the server:

  • Da certbot den http Zugriff auf bone.nfix.de benötigt, muss in der Fritzbox das Port 80 freigegeben sein.

Radicale auf BBB (Logging: OSError: [Errno 30] Read-only file system: '/var/log/radicale/log')
16.02.2019 - Lesezeit: ~1 Minute

Nachdem ich auf meinen BBB von Ubuntu 16.04 auf Ubuntu 18.04 gewechselt hatte musste ich feststellen, dass das der Radicale-Server nicht mehr lief.

Der Befehl $ journalctl --unit radicale.service -e liefert u.a. diese Fehlermeldung:

OSError: [Errno 30] Read-only file system: '/var/log/radicale/log'

den Radicale-Server anhalten

$ sudo systemctl stop radicale

Da ich nicht herausgefunden habe, warum das Filesystem Read-Only sein soll habe ich in 

$ sudo nano /etc/radicale/config

das Logging ausgeschaltet

[logging]
## config = /etc/radicale/logging
## debug = True

den Radicale-Server wieder starten

$ sudo systemctl start radicale

pyperclip unter Kubuntu 18.04
21.01.2019 - Lesezeit: 2 Minuten

Mit pyperclip möchte ich einen Text ins Clipboard kopieren.


import pyperclip

def main():
    aClipboard = "Dieser Text soll ins Clipboard"
    print(aClipboard)
    pyperclip.copy(aClipboard)
    print("beendet.")
    return 0

if __name__ == '__main__':
    main()

Das Script liefert die folgenden Warnungen und der Text wird nicht ins Clipboard kopiert. Dieser Text soll ins Clipboard (test_pyperclip.py:17789): Gtk-WARNING **: 06:38:59.827: Theme parsing error: gtk.css:68:35: The style property GtkButton:child-displacement-x is deprecated and shouldn't be used anymore. It will be removed in a future version

(test_pyperclip.py:17789): Gtk-WARNING **: 06:38:59.827: Theme parsing error: gtk.css:69:35: The style property GtkButton:child-displacement-y is deprecated and shouldn't be used anymore. It will be removed in a future version

(test_pyperclip.py:17789): Gtk-WARNING **: 06:38:59.827: Theme parsing error: gtk.css:73:46: The style property GtkScrolledWindow:scrollbars-within-bevel is deprecated and shouldn't be used anymore. It will be removed in a future version beendet.

Da ich die KDE benutze gehe ich davon aus, dass pyperclip das falsche Clipboard anspricht. Mit pyperclip.set_clipboard('klipper') kann pyperclip dazu übereredet werden klipper als Clipboard zu benutzen:

import pyperclip

def main(): aClipboard = "Dieser Text soll ins Clipboard" print(aClipboard) pyperclip.set_clipboard('klipper') pyperclip.copy(aClipboard) print("beendet.") return 0

if name == 'main': main()
