The following works very good for me sudo vi /etc/init.sh add 4 lines below to init.sh netcfg eth0 dhcp echo nameserver <ip> > /etc/resolv.conf dnsmasq setprop net.dns1 8.8.8.8 on virtualbox set the network interface to bridged (PCnet Fast III) and that’s all.
To locate interface In my case getting value from container was like (check eth0 to): $ docker exec -it my-container cat /sys/class/net/eth1/iflink 123 And then: $ ip ad | grep 123 123: vethd3234u4@if122: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue master docker_gwbridge state UP group default Check with tcpdump -i vethd3234u4 Reference about mysterious iflink from http://lxr.free-electrons.com/source/Documentation/ABI/testing/sysfs-class-net: … Read more
Interfaces In arbitrary order of my familarity / widespread relevance: lo0 is loopback. en0 at one point “ethernet”, now is WiFi. en1 and en2 offer IP over Thunderbolt, according to for IF in en1 en2; do ifconfig -v $IF; done. H/T @Mojo66 below. fw0 is the FireWire network interface. stf0 is an IPv6 to IPv4 … Read more
There’s no eth0 on default configuration of OS X. By default, en0 and en1 are your physical network connections (wired and wireless LAN). lo0 is the loopback interface. fw0 is the IP over Firewire interface; and vmnet interfaces are installed by VMware for network communication with virtual machines.
You can use sudo ip link delete to remove the interface.
On a fresh ubuntu docker image, run apt-get update apt-get install net-tools These can be executed by logging into the docker container or add this to your dockerfile to build an image with the same.
You can try with: route -n get default It is not the same as GNU/Linux’s route -n (or even ip route show) but is useful for checking the default route information. Also, you can check the route that packages will take to a particular host. E.g. route -n get www.yahoo.com The output would be similar … Read more
Use grep to filter IP address from ifconfig: ifconfig | grep -Eo ‘inet (addr:)?([0-9]*\.){3}[0-9]*’ | grep -Eo ‘([0-9]*\.){3}[0-9]*’ | grep -v ‘127.0.0.1’ Or with sed: ifconfig | sed -En ‘s/127.0.0.1//;s/.*inet (addr:)?(([0-9]*\.){3}[0-9]*).*/\2/p’ If you are only interested in certain interfaces, wlan0, eth0, etc. then: ifconfig wlan0 | … You can alias the command in your .bashrc … Read more
