11.5.1 : configuration de base d’un périphérique Cisco


Étant donnée une adresse IP de 198.133.219.0/24, avec 4 bits empruntés pour des sous-réseaux, ajoutez les informations suivantes dans le tableau ci-dessus, soit sur votre ordinateur portable, soit sur une feuille de papier. (Conseil : ajoutez d'abord le numéro de sous-réseau, puis l'adresse d'hôte. Les informations d'adresse seront faciles à calculer si le numéro de sous-réseau est ajouté en premier.)
Nombre maximal de sous-réseaux utilisables (n'oubliez pas le premier sous-réseau, numéroté 0) ? 
Nombre d'hôtes utilisables par sous-réseau ?

Solution : 4 bits = 15 sous réseaux ( 15 sous réseaux alors il nous faut 16 @ 16= 8*2 )
Nombre d’hôtes utilisables par sous-réseau : ________14_________
( 2*n -2 = 2*8 -2 = 14 )

Adresse IP : 198.133.219.0  Masque de sous-réseau : 255.255.255.240

cPanel DDOS attack - Mitigate Slowloris Attacks - mod_qos

Apache mod_evasive Mod_evasive is a module available for the Apache HTTP server that can automatically block attacks by rate-limiting any IP that sends too many requests in a short time. Start by installing the module from WHM’s  EasyApache 4  interface. Select the  Currently Installed Packages  profile, search for  mod_evasive  in the  Apache Modules  section, and then install it. The default settings are good for most servers, but you can tweak them further by editing the configuration file  /etc/apache2/conf.d/300-mod_evasive.conf . You can also whitelist specific IP addresses or classes, so legitimate requests are not blocked. Configure CSF to block attacks While  mod_evasive  works very well, it only protects the Apache webserver. In order to harden other services as well, you can install the free  ConfigServer Security & Firewall  (CSF), which also includes a WHM plugin. As the  root  user, install CSF with these terminal commands: cd /usr/src rm -fv csf.tgz wget https://down

Unknown Root Password, but Admin Access to OMV GUI is Available In this scenario we still can help ourselves with the GUI. The method we use is, that we create a cron job for the root user which then resets the password. Navigate to System -> Cron Jobs Press the +Add button UN-tick the enabled box, so that the cronjob does not run automatically. put into the command field the following line, replace newpasswd with your password: echo "root:newpasswd" | chpasswd press okay select the newly created cron job Click the run button. in the opening window click the start button. It will shortly deactivate and activate again. open ssh or console and login as root with your new password.
