I could ping the machine. But I could not access the machine using telnet in windows. The servers is linux machine. Do you have any idea ?

Your firewall is blocking off the telnet port and probably the rest of the ports cassandra needs. You need to add an exception telling the firewall to open port 9160 (the client port). 9160 is the only port you really need to have open unless you want remote jmx management etc.

To add an exception to your linux firewall: 

iptables -I INPUT -p tcp --dport 9160 --syn -j ACCEPT

And if you want to save the state: 

service iptables save
