Refuse responding to broadcasts request As for the ping request, it's also important to disable broadcast requests. When a packet is sent to an IP broadcast address (i.e. 192.168.1.255) from a machine on the local network, that packet is delivered to all machines on that network. Then all the machines on a network respond to this ICMP echo request and the result can be severe network congestion or outages DOS (Denial-of-Service attacks). See the RFC 2644 for more information. Step 1 Edit the sysctl.conf file (vi /etc/sysctl.conf) and add the following line: # Enable ignoring broadcasts request net.ipv4.icmp_echo_ignore_broadcasts = 1 Step 2 Once the configuration has been set, you must restart your network for the change to take effect. The command to restart the network is the following: To restart all networks devices manually on your system, use the following command: [EMAIL PROTECTED] /]# /etc/rc.d/init.d/network restart Semoga bener ... :-) ----------------------------------------- This email was sent using linuxius mail system.
