No matter if the local software firewall is blocking those packets, or not. It should be emphasized they do see, they can capture, any inbound packets that reach the local NIC. Tcpdump, and its underlying library libpcap, are multi-platform user space interfaces to the packets on the network. Traceroute also used ICMP to determine the path and hence there can be "no reply" answers as well when ICMP traffic is blocked. When no reply is received, tracepath or traceroute can be used to verify the routing towards said server and get an idea of where the issue lies. The next step is verifying connectivity towards the configured dns server(s). This message can also be displayed when ICMP traffic is not permitted towards the default gateway (blocked by a firewall, router.). When instead a " Destination Host Unreachable" message is displayed, doublecheck the ip address, netmask and default gateway config. The output above indicated the default gateway is reachable.

It can be aborted by hitting "Control-C". This has been a problem since the day it was set up and I have been unable to resolve it. I currently cannot connect to this machine from the local network nor can I connect to the internet or the internal network from the server. When erasing the "-c4" parameter, the ping will continue endlessly. I have set up a Red Hat Enterprise Linux Server Release 6.5. netctl is the standard utility for managing network interfaces in Arch. If you cant even ping the local router, either you dont have an IP address or your network interface is down. The first step would be verifying connectivity towards the default gateway (replace the ip address with your own default gateway): Network unreachable means you dont have a route to the network.
The ping command can help test connectivity towards a specific host. Would be glad for some answers.Notes: duplicate (Discuss in Talk:Network Debugging) My own answer is (but I am not sure), the domains in the /etc/hosts file are used for a local network (LAN), so every hostname should go through the router to another computer, except localhost and the own server, here brauneck.sul. Is it possible at all to send a ping-command to a domain in /etc/hosts? Or is it just in the old Linux Debian Lenny impossible? It would be very nice if someone can point me in the right direction. I get "Destination Host Unreachable" or "Network is unreachable". Ping 8.8.8.8 gives me: connect: Network is unreachable.
It doesn't matter whether the netword-card is up or down, I can ping localhost and my computer's name "brauneck.sul", but not the domainname in the /etc/hosts file. The searching order in nf is: First files, then dns!Īdditional I put the order in the file /etc/nf, first hosts and then bind - "order hosts bind", but it seems not necessary. I put "in the /etc/hosts file with the IP Nr. To send a ping-command to localhost and brauneck.sul works without problems.
