shell – Write script for adding the eth0 interface on S7 edge

Can anyone see this script? I want to put it in a sh file. When I connect my Ethernet adapter, I don't want to re-enter all commands. I just want to run it from the shell. Is that correct?

#!/bin/sh
ip link set eth0 up
sleep 1;
ip addr add 192.168.178.50/24 dev eth0
sleep 1;
ip route add default via 192.168.178.1 dev eth0
sleep 1;
ndc network create 1
sleep 1;
ndc network interface add 1 eth0
sleep 1;
ndc resolver setnetdns 1 8.8.8.8 8.8.4.4
sleep 1;
ndc network default set 1

Galaxy S7 Edge Setup eth0 interface with USB / Ethernet adapter

The Galaxy S7 has no Ethernet settings like other devices like the Galaxy S8. So I rooted my phone and installed the Nethunter kernel that supports Ethernet.

I opened the terminal emulator and typed lsusb and my phone recognizes the ethernet adapter. It is a Realtek RTL8153.

Then I connect it to my Rj45 cable and type: dhclient eth0

it seems to work because ping -c 4 www.google.de Give answers. But the strange thing is that apps don't recognize the eth0 interface. I can't surf or download apps from Google Play.

Thank you in advance.

Linux – host unreachable if eth0 does not have IPv4 in the ethernet bridge

I am currently trying to configure an Ethernet bridging VPN using OpenVPN. However, when I try to set up the Ethernet bridge, the server (Raspberry Pi) loses the connection to the internal network. I use the following script to initialize my ethernet bridge

#!/bin/bash
# Define physical ethernet interface to be bridged
# with TAP interface(s) above.
eth="eth0"
eth_ip="192.168.144.200"
eth_netmask="255.255.255.0"
eth_broadcast="192.168.144.255"
eth_gateway="192.168.144.1"
eth_mac="B8:27:EB:48:6D:E3"


# Define Bridge Interface
br="br0"

# Define list of TAP interfaces to be bridged together
tap="tap0"

#################################
# Set up Ethernet bridge on Linux
# Requires: bridge-utils
#################################

for t in $tap; do
    openvpn --mktun --dev $t
done

brctl addbr $br
brctl addif $br $eth

for t in $tap; do
    brctl addif $br $t
done

for t in $tap; do
    ifconfig $t 0.0.0.0 promisc up
    iptables -A INPUT -i $t -j ACCEPT
done

iptables -A INPUT -i $br -j ACCEPT
iptables -A FORWARD -i $br -j ACCEPT

ifconfig $eth 0.0.0.0 promisc up
ifconfig $br $eth_ip netmask $eth_netmask broadcast $eth_broadcast
ip link set $br address $eth_mac
dhclient $br
ifconfig $br promisc up
route add default gw 192.168.144.1

After debugging the entire story, I found out that

ifconfig $eth 0.0.0.0 promisc up

leads to my connection problem. Any ideas on how to solve this problem? Normally, only the bridge interface should have an IP address. But if I do not assign eht0 an IP address, the terminal connection is broken off and I can no longer connect.

Note: I have already checked iptables and net.ipv4.ip_forward is set to 1,

iptables – cloud-netconfig: Adding many addresses to the eth0 interface

We have IPTABLE (Natting) servers with SLES 12 on Azure. We have assigned multiple IPs on the network interface to a VM but not configured in the guest operating system.
This command creates NAT rules to forward traffic to servers that are inaccessible in a local environment. Now the communication is good and also the access to the remote server is done according to NAT rules.

iLO + eth0 with 1 IP address?

I intend to merge my server, but the host only offers me an IP address. Technically, there are 4 IP addresses (1 usable).

I have a server with an iLO port. Is it possible with 1 IP address and 1 uplink to set up a setup where I can still access iLO through another interface, using that single IP address?

I've also been told how to set up a VPN for the iLO port.

What do you think about it?

Networking – No eth0 on new Debian installation

I have just installed Debian 9 on a Dell XPS 13. Since it only has USB-C ports, I use the Dell DA200 dongle for Ethernet. However, it appears that the Ethernet port is not recognized because eth0 is not listed in the input ip a, I have already added the following / etc / network / interfaces

car eth0
allow-hotplug eth0
iface eth0 inet dhcp

I can not use apt-get update / upgrade / install because I do not have an internet connection. Is there something I can solve now?

Networking – How can I map requests for wlan0 to eth0 as root?

I'm trying to develop an application backwards, and I need to resolve a soft reset loop. I'm using Android x86 for Android 2.2 (Froyo) in Virtual Box since the app is for Android 2.2. The cause of the soft reset seems to be the error in getting the MAC address for wlan0. I do not think I can create a wireless interface directly in the emulator.

Current line of output:

/ sys / class / net / wlan0 / Address not found

I want wlan0 to be a copy of eth0. How do I do that?
