Sendto network is unreachable linux how to#
One thing I've read is that I need to specify my router in the routing table somehow, but I don't even know the router's address and I have no idea about how to find it out either (because I'm nothing like a networking expert and IPv6 seems even more confusing than IPv4 to me). Route -6 returns: Destination Next Hop Flag Met Ref Use Ifįe80::16da:e9ff:feb6:357e/128 :: Un 0 1 391 loįe80::4c7b:2bff:fef4:9db/128 :: Un 0 1 0 loĪnother strange thing is, pinging my own IPv6 address only works if I tell ping6 to specifically use the eth0 interface with -I eth0 otherwise that'll return unknown host. Network is unreachable piraspberrypi ping ping: unknown host.

TX packets:* errors:0 dropped:0 overruns:0 carrier:0 I have a Raspberry Pi 2 Model B V1.1 running Raspbian (Im not a confident Linux user, but I understand this is the 'Jessie' distribution) and have been using it to install matplotlib and other MATLAB-esque packages to work on audio DSP. RX packets:* errors:0 dropped:0 overruns:0 frame:0 Stack Exchange network consists of 178 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 but from couple of days i m facing this issues. On the Linux side, I can ping the loopback and the machine itself, but when I try to ping another machine, I get. i am doing this from 2.5 months(i guess) it was working fine anyway. Inet6 addr: fe80::16da:e9ff:feb6:357e/64 Scope:Link 'Errno 101 Network is unreachable' i am only sending outputs into emails. Ifconfig looks like (a tad censored): eth0 Link encap:Ethernet HWaddr **:**:e9:b6:35:7e Ping6 just tells me connect: Network is unreachable when I try to ping for example. It says: Network is unreachable Then I typed: ifconfig: inet addr: 192.168.56.101 Then: sudo /sbin/route add -net 0.0.0.0 gw 192.168.56. If your want to use the "Host Only Adapter" then it may be possible, that you first have to create an "Host Only Network" under File->Preferences choosing the tab "Host Only Networks".So, my problem is that I just can't get IPv6 to work. I am working on a VM: In the terminal, I'm trying to: ping 8.8.8.8 to see my connectivity. Iptables -t nat -A POSTROUTING -o -j MASQUERADE On your host machine your should activate ipv4-forwarding and NAT to get internet access: echo 1 > /proc/sys/net/ipv4/conf/all/forwarding Then configure the IP address of the VM host only adapter to be the default gateway of your VM guest. In the case you are working in a VM (I see it is Virtual Box) try to find out the IP address of the "Virtual Box Host Only Adapter" on your host machine (command: ifconfig or ipconfig). If you don't know your default gateway for this interface, so try to get a valid default gateway for this interface via DHCP configuration (configure this interface to be a DHCP client). You need another default gateway in the same subnet to be happy. An interface gateway should be in the same subnet as the interface itself, but it should never BE itself.
Here are the steps I took, following the wiki article for Networking : ip link set eth0 up ip link 1: lo:103 so I change it back, however the site cannot be seen and I cannot connect to it using putty. Network unreachable (from Netboot image) Hi I have installed a Netboot image in my ESP, I can boot it correctly but I cannot establish any connection. When I login locally and try and ping google.ca I get 'Connect : Network is unreachable' ifconfig eth0 shows the ip address has changed to a. That means: When your computer does not know where to send a package it sends it to itself respectively to one of its own interfaces. This started this morning, I woke up and my site was there, checked my mail, and then my site was gone. In your case the default gateway is exactly the same as your interface IP. Which in turn tries to find the destination. Then theĭestination address lies outside of the interfaces subnet. Second case: Say the destination IP of the incoming package isġ0.20.40.40 and the interface on which the package arrives is configured to be 10.20.30.1 netmask 255.255.255.0. (it says "Here is a package that is addressed for someone in my own Then your OS will forward the package to the broadcast 10.20.30.255 Packages destination subnet and the interfaces subnet are the same. There are two cases what a computer can do, when it has to forward an IP package:įirst case: Say the destination IP of the incoming package isġ0.20.30.40 and the interface on which the package arrives is configured to be 10.20.30.1 netmask 255.255.255.0.
