Not Able To Ping Ip Address In Linux You can test HTTP connectivity using any Telnet application that allows a port number to be specified by Telnetting to the IP address of the destination server on port 80.
We appreciate your feedback. Solution: CHECK YOUR NETWORK SETTINGS…?????? To view the IPv4 routing table, use the route print or netstat –r commands.
