Cómo evitar que iptables envíe logs a la consola

Cada vez más a menudo encuentro servidores que muestran directamente logs de iptables directamente en la consola, lo que hace muy difícil poder iniciar sesión y trabajar directamente en un terminal TTY. Evitarlo es muy sencillo tanto en Debian GNU/Linux como en Ubuntu: 

  • Editar el fichero /etc/sysctl.conf 
    kernel.printk = 4 1 1 7
    
  • Aplicar los cambios ejecutando:  
    sudo /sbin/sysctl -p /etc/sysctl.conf
  • Verificar los cambios ejecutando:
    cat /proc/sys/kernel/printk

Esta entrada es un resumen de esta entrada "How to configure syslog..."

XRumer...
In the long run, XRumer is a profitable investment
If you are the owner of an online store or Internet service, you probably know how expensive advertising in Yandex Direct or Google AdWords is. Properly using the “XRumer + Hrefer + SocPlugin” complex, you get the opportunity to receive the targeted visitors you need for only $ 10 per month.

In the course of its work, the XRumer program is able to recognize captcha by automatically downloading the picture and decrypting it. As practice has shown, decoding this type of captcha takes no more than 1-1.5 seconds, and usually even less on a computer with a processor with an operating frequency of 1 GHz. Traffic on this takes quite a bit, because such pictures "weigh" no more than 3-5 Kb.
