Denyhosts SSH for SME7

Maintainer

Unnilennium aka Jean-Philippe PIALASSE (Contrib)

Description

  • Denyhosts bans hosts which failed too many login attempts to your ssh deamon.
  • It contains also a panel in the server manager to see who is blocked, add some allowed hosts not to block and enable or disable the service.


it needs the packages smeserver-denyhosts and denyhosts

Installation

  1. Log in (with username root) to the SMEserver console.
  2. Install smeserver-denyhosts
    /usr/bin/yum install smeserver-denyhosts --enablerepo=smecontribs
    You will get a y/N-question, answer y if it looks fine. There is no need to reboot the server.
  3. Open your webbrowser and go to the server-manager.
    Under "Security" there should be a new line named "SSH Denyhosts". You should go to it and configure all necessary allowed hosts before enabling the service. When done set status to 'enabled'.


Alternatively you can use the server-manager panel "Software installer" to add a new package and select smeserver-denyhosts (repo smecontribs must be enabled) then do the reconfiguration and reboot task, instead of steps 1 and 2, then refresh your browser and configure denyhosts,.

cp ../../../templates/etc/denyhosts.conf/* .

Now edit the appropriate files. See the Denyhosts FAQ for details. When done make your changes effective: 

signal-event conf-denyhosts
