To enable IP forwarding temporarily (until the next reboot):
echo 1 > /proc/sys/net/ipv4/ip_forward
To enable permanently, edit /etc/sysconfig/network and change or add the following line:
FORWARD_IPV4 = YES

		<description><![CDATA[Many malicious attacks begin with a ping scan.  Disabling ICMP echo requests prevents your system&#8217;s discovery with a ping.

As superuser, add the following lines to /etc/sysctl.conf
net.ipv4.icmp_echo_ignore_broadcasts = 1
net.ipv4.icmp_echo_ignore_all = 1
Then run the following command to cause the change to take effect immediately:
sysctl -p
This change will persist following a reboot.

Running the following command as superuser with no options will generate basic information about all of the Ethernet interfaces on the computer:
mii-tool
The resulting output will look something like:
eth0: negotiated 100baseTx-FD, link ok
This output shows one interface (eth0) which was auto-negotiated to 100 Mbps (100baseTx) [...]]]></description>

		<description><![CDATA[Using mii-tool, the speed and duplex of an ethernet interface can be set manually.

You must set both the speed and duplex at the same time (it is not possible to auto-negotiate only one).  Typical combinations are the following: 
100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD
To set 100 Mbps and full duplex on interface eth0, for example, use:
mii-tool [...]]]></description>
