No Route to Host error and solution
No Route to Host error and solution I am getting error that read as No Route to Host. I am trying to ping my ISP gateway as well as DNS server but I am getting this error. How do I solve this problem? Make sure firewall is not blocking your access iptables is default firewall on Linux. Run following command to see what iptables rules are setup: # /sbin/iptables -L -n You can temporary clear all iptables rules so that you can troubleshoot problem. If you are using Red Hat or Fedora Linux type command: # /etc/init.d/iptables save # /etc/init.d/iptables stop If you are using other Linux distribution type following commands: # iptables -F # iptables -X # iptables -t nat -F # iptables -t nat -X # iptables -t mangle -F # iptables -t mangle -X Finally make sure you are using a router and not a proxy server. Proxy servers are good for Internet browsing but not for other work such as ftp, sending ICMP request and so on.
