In this user guide, we will identify some possible causes that can make the icmpseq 1 target host unreachable and then provide possible fixes that you can try to solve for this problem. The target network is not available to the host. This means the host you are trying to ping is down or not online.

My other electronic devices can PC ping mon, but PMon c cannot ping any other devices, including a router to which PMon c can be directly connected. sure

I will check the conflicting email IP address on another device.

(Though I’m not sure if your ping results actually match this. It’s not actually my guess with ARP, and unfortunately I couldn’t find similar combinations near Google search results Maybe one or more types of problems are considered additional problems, but this is very useful, check and the situation may help you find clues).

On your computer you will find the MAC address (“hardware address”). When you run ip link Advertising dev on MAC address eth1 is an integer value displayed after link/

On the other hand, I would say that for other devices, carefully check what the MAC address cached on it means for your IP address If you see another device running Linux, someone in the ARP cache can check using neighbor ip-4 . If the Windows device is workingmelts, you can check the ARP cache with -a using arp (on the Windows command line). other If the For mac property shows your IP address as 146, you actually pinged another resource, not your :-) computer.

What Is The Most Likely Reason You Are Not Secure Enough To Ping?

AfroJoe: so many reasons

Technically, a ping message saying "Destination Host Unreachable" is a pretty specific error description! Your output almost certainly indicates that arp is not working. To For example, this turned out to be the same computer the buyers had on the On, running ping and you found out about in this later edit. In this case, you can confirm the ARP problem easily, as it's called:

Note. interpretation This only applies to ping. This is far from the case, if you are using a "regular" TCP/IP application such as ssh or curl received an absolute "Host Unreachable" message, reality can also set toReceived response about ICMP, error available, for example, as "Forbidden by the administration" (from the firewall). However, it receives the ping in full and decrypts the ICMP response. Thus, ping will tell you that you are seeing a specific error "Forbidden by the administration, and most recently not available" "Host.togo,

Except these questions and answers apply to IPv4. I probably didn't check how it can be adapted to IPv6.

How do I fix destination host unreachable?

Try disabling the firewall and check for problems.TraceIt's better to get to the target IP address and check where the fault occurs.Make sure the localhost is created correctly.

AfroJoe: So Reasons

A lot of me will have a different approach to knowledge. Your Ubuntu client gadget has been specially configured by someone, this address was nicely assigned by exchange dhcp packages. Typically, the exchange uses a hub, although in other cases it may be a single Windows server or a different type of server. In this case, the router is still a DHCP server or relay, and the system may already be exchanging some packets with the router.

You can try restarting exchanges via DHCP as well as you and disconnect to reconnect.[*] Of course, the problem is if you don'tm go back, doing it will not "accidentally" solve the underlying problems, you and possibly learn more about the connection while it keeps dropping.

([*] Apple has written optimizations understanding that can quickly make After dhcp paging a special ARP block paging. There may be some new features, but I haven't seen it on Linux yet.)

This particular error is common when connecting to DHCP via when wi-fi, the wi-fi signal is usually lost at some point. Someone (and before that I caught that the wireless layer completely gives up ... I don’t know why I used it so often, maybe I probably observed buggy or poorly written systems and published it). But eth1 is not suitable for Wi-Fi.

I believe DHCP works many for IPv4 without ARP. Less au in exchange rather DHCP.

Other Options

Based on the facts, when the first version of your speculation began, I had a hard time remembering anyone whose script was particularly routine. (Including my implicit assumptions. It is unlikely that anyone will download this question, trying not to connect their computer to a convenient router). Network to

    How do I fix virtualBox unreachable destination host?

    Restart the machine.Go to Control Panel/Network Center.Then proceed to change the map settings.Disable "virtualBox, they only host "virtualBox network"Enable only for your host network"Now ping any static IP address.Results: No errors. Works great.

    How do I fix ping destination host unreachable in Linux?

    The main reason for interacting with the "Destination Host Unreachable" echo request comes down to too many policy protection settings. If you are not using a connection firewall, a simple misconfiguration can prevent ping from working properly. You will definitely verify this by disabling the firewall software and pinging the target IP address again.
