1) Edit file /etc/sysconfig/network using your favourite editor.
vi /etc/sysconfig/network
2) Look for HOSTNAME=xxxxxx
3) Change the xxxx to the name you wish to set for your computer. (ex:HOSTNAME=abc.com)
4) Save the file and restart the network service. (ex: type service network restart in your shell)
Done! You have just changed your hostname in Linux platform
The following firewall rules will drop ICMP requests.
iptables -A OUTPUT -p icmp -d 0/0 -j DROP
echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_all
Additionally, upon discovering a repeated attack host, the /etc/hosts.deny file is updated to prevent future break-in attempts from that host. An email report can be sent to a system admin.
# crontab -e
The above command will launch the crontab editor. To launch DenyHosts every 20 minutes you would then add the following line to the crontab:
0,20,40 * * * * python PATH_TO_DENYHOSTS/denyhosts.py -c PATH_TO_DENYHOSTS_CONFIG/denyhosts.cfg
You will need to substitute your site-specific paths above. As an example, if you installed DenyHosts in /usr/local/etc and maintain your configuration file there as well, then the following crontab entry would be appropriate:
0,20,40 * * * * python /usr/local/etc/denyhosts/denyhosts.py -c /usr/local/etc/denyhosts/denyhosts.cfg
Once you have edited the crontab you should then save it. Assuming you didn't make any errors, the crontab will automatically install itself.
There are other lot's of option you can use - visit and download DenyHost
