You may go through the instructions provided in the link below to learn more about it. If you are getting valid replies from localhost, next you must ping any DNS address. ping any value in those range should work if your network stack is working on your OS. A loopback address is an address used by the system to validate the network stack of the OS. How to check my Local Network Connection issues 0.1 is the default loopback of most system. To get more inputs about this issue, I suggest you visit the link below. Also, verify the quality of Ethernet cable. Verify the Ethernet cable connected properly between your LAN port and Modem/router. Here we must make sure there is no loose connection or faulty cable. To learn how to do it, I recommend you to visit the link below.Īfter verifying the status of the TCP/IP suite, we must check the network connection. netsh winsock reset - doesnt work - The system cannot find the file specified 3. If not, you must reset the TCP/IP suit on your computer. ping to loopback interface fails - ping 127.0.0.1 - general failure 2. If you are getting replies, then the TCP/IP suite is fine. On the command prompt type, the following command ping 127.0.0.1 and press enter key. Click on run and type cmd on it then click OK(On Vista type command on search and press enter).However, it is important to verify it by sending ping packets to 127.0.0.1 and analyze the reply. If you are getting a reply from the loopback address it shows the TCP/IP suite is working on your computer. There is no internet connection from your service provider. On a FreeBSD system with a loopback network interface ifconfig lo0 lo0 link up loopback drvrunning running multicast nd6 performnud autolinklocal noradr link rxcsum txcsum hwcsum rxcsumipv6 txcsumipv6 link address metric 4 type 24 linkstate 0 physical 0 baudrate 0 inet4 address 127.0.0.1 prefixlen 8 bdaddr 127.0.0.The TCP suit on your computer might be corrupted.Possible reasons from no valid reply from DSS server though I get replies from loopback address are: However, when I ping 127.0.0.1, I am getting valid replies. Hmm, ping localhost seems to work on Windows even without the hosts file pointing 127.0.0.1 to localhost. So, for gentoo, you can just start the loopback interface with /etc/init.d/net.lo start and add it to the boot runlevel with rc-update add net.lo boot.Here I ping 4.2.2.2 from the command prompt but it failed to get a valid reply from it. The loopback adapter with IP address 127.0.0.1 from the perspective of the server process looks just like any other network adapter on the machine. It turned out that net.lo had been removed from all runlevels (probably by me when I was screwing around with eth0/eth1). The solution was simply to start the loopback interface and add the loopback route to the routing table.Ħ4 bytes from localhost (127.0.0.1): icmp_seq=1 ttl=64 time=0.053 msĦ4 bytes from localhost (127.0.0.1): icmp_seq=2 ttl=64 time=0.045 msĢ packets transmitted, 2 received, 0% packet loss, time 1000ms For most purposes, though, it is only necessary to use one IP address, and that is 127.0.0.1. TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 For IPv4, the loopback interface is assigned all the IPs in the 127.0.0.0/8 address block.
