My goal is to change the IP address of USB0.
The Beagle Bone Black run Debian.
I tryed to change /etc/network/interfaces such that default address is 192.168.7.3 instead of 192.168.7.2 as this:
iface usb0 inet static
address 192.168.7.3
netmask 255.255.255.0
network 192.168.7.0
gateway 192.168.7.1
After running
/etc/init.d/networking restart
It was still on 192.168.7.2.
I tryed rebotting, and yet is to no avail.
I tryed to change the IP address in /boot/uboot/scripts/setup-ubuntu-armhf-3.8.13-bone30.sh, but basicly this file overwrites /etc/network/interfaces.
Still after reboot the IP is still 192.168.7.2.
Edit:
Also tryed to change the IP in:
/media/Angstrom/usr/bin/g-ether-load.sh
/media/Angstrom/etc/udev/rules.d/udhcpd.rules
Which didn't work.
Tryed to change it in:
/opt/scripts/boot/am335x_evm.sh
And now the network is unreachable:
ssh: connect to host 192.168.7.3 port 22: Network is unreachable
I was having the same problem on:
BeagleBoard.org Debian Image 2017-03-19
The issue turned out to be "connmand" (read it again, it starts with coNN, not comm). It is a horribly named program as it is difficult to research as Google assumed you spelled something wrong.
connman automatically configures wired instances for dhcp despite what is listed in /etc/network/interfaces.
Recommend either disabling it, or adding your interface to be ignored:
/etc/connman/main.conf:
NetworkInterfaceBlacklist=SoftAp0,usb0,usb1,eth0
After doing that and restarting, my static IP configured for eth0 in /etc/network/interfaces started working.

I wanted to use my android phone as a display for my Raspberry Pi 4B, so I searched the internet, found an instruction and copied the code into my Pi, I was connected to (via SSH). This is the code I put into /etc/network/interfaces:
iface usb0 inet static
address 192.168.42.42
netmask 255.255.255.0
network 192.168.42.0
broadcast 192.168.42.255
This sets the IP to a static one (192.168.42.42).
I rebooted and tried to SSH with IP 192.168.42.42, because I thought, this was the new IP for the Raspberry Pi.
Long story short, it doesn't work. I also tried some other IP's, I cant find the IP in NUTTY or with nmap.
How can I connect to my PI now? (I don't have a monitor or a crossover LAN cable)
I'm using an older MacBook Pro with Linux Mint 19
Where I got the code from: https://joshuawoehlke.com/android-raspberry-pi-display-over-usb/
You could take the SD card out of the Pi and put it in your Mac/Linux machine and correct/remove the /etc/network/interfaces file from the SD card.
Or, you could go to the SD card's /boot partition and touch ssh in that directory so that sshd starts and also create in that same directory a wpa_supplicant file to match a temporary WiFi hotspot you create on your phone or Mac. Then you can ssh into it over WiFi and whatever you want.

I have some code that uses system commands to set the IP address and default gateway in Linux.
It works, but when the Linux OS is restarted, it reverts back to the old IP address.
Here are the commands used, addresses changed here.
ip link set eth1 down
ifconfig eth1 0.0.1.2 netmask 255.255.255.0
route add default gw 0.0.1.2 eth1
ip link set eth1 up
Is there another place in Linux where the IP address needs to be set, that 'ifconfig' does not change?
Thanks in advance for any replies.
For Static IP address assignment
Debian/Ubuntu Base Distro :- you can edit /etc/network/interfaces file, which contains information about the Network Configuration.
RedHat/CentOS Base Distro, you can edit /etc/sysconfig/network file.
If you can't find either of the files, then append the following commands to either ~/.bashrc or /etc/bash.bashrc file in your linux machine
ip link set eth1 down
ifconfig eth1 0.0.1.2 netmask 255.255.255.0
route add default gw 0.0.1.2 eth1
ip link set eth1 up
~./bashrc is user specific file and /etc/bash.bashrc is common for all users. Whenever the any user login to system, and you have added the mentioned commands in /etc/bash.bashrc file, then these commands will be executed by the system. The user won't have to execute these commands manually.

How to permanently configure static IP Address of Bitnami Backendless Standalone Linux version?
The Bitnami VM comes configured to use DHCP.
The Bitnami FAQ says you can change the IP address using the command below:
An alternative approach is to configure the network manually and assign a static IP address to the virtual machine. For example, if your local network uses IP addresses of the form 192.168.1.X and you know that the IP address 192.168.1.234 is unassigned, manually assign this to the virtual machine by executing the command below at the virtual machine console:
sudo ifconfig eth0 192.168.1.234 netmask 255.255.255.0 up
Unfortunately, the IP Address is only assigned until the server is rebooted. After rebooting the VM, the IP address is dynamically allocated using DHCP.
ifconfig changes the IP Address only during the system runtime.
Depending on your Linux distribution, you've got to change the network setting by editing the related files.
Debian/Ubuntu
$ sudo vi /etc/network/interfaces
Fedora/Centos
$ sudo vi /etc/sysconfig/network-scripts/ifcfg-eth0

when I put this in the terminal
ifconfig eth0 69.69.69.69
the ip address in the terminal change but in the user interface not, I mean
initial state
my ip is 192.168.10.2
then a put in the terminal
ifconfig eth0 69.69.69.69
and this happens
terminal
properties
As we can see the properties didn't change.
what can I do for change that properties using the terminal or a bash?
You are probably using a Linux distribution that uses the NetworkManager daemon, and during installation it decided that eth0 should be configured via DHCP. So every time you manually setup its IP not using it (from a terminal in your case), NetworkManager will set it up again without noticing you within a few seconds or minutes.
To check if you have indeed NetworkManager running and managing eth0 setup, issue:
ps aux | grep -i networkmanager
If it is indeed running, look for more info about it, from Ubuntu for instance:
https://help.ubuntu.com/community/NetworkManager
...and then google around for "network manager manual setup ip".
PS:
I hate NetworkManager with a deep passion, gave up using it years ago and always uninstall it, managing my interfaces manually and/or the good old /etc/network/interfaces way. Noticeably (in my case) it can be a pure nuisance when multihoming and changing the interfaceS setup frequently. So if this is indeed your problem (90% sure) I can't help you much more with it. NetworkManager is good at managing one interface at a time, with one configuration (ex static or DHCP) for each interface. This satisfy 95% of user cases. But not mine.
i have try this in my computer and i have success
ifconfig eth0 192.168.218.110
if you want to chang the /etc/sysconfig/network-scripts/ifcfg-eth0 to chang the ip.
you can use vim edit chang thhis line:IPADDR=192.168.218.111

I have created a virtual interface using
ifconfig eth0:1 192.168.50.10 netmask 255.255.255.0 up
Now I'm sending a request to a server via the virtual interface using curl:
curl --interface 192.168.50.10 http://192.168.50.1:8080/myhostedapp
This works fine and my app shows the source ip as 192.168.50.10, but if the server is on a different subnet, and reachable from the physical interface (eth0), the connection times out.
So this works (via the physical interface):
curl http://10.10.50.1:8080/myhostedapp.
But this fails:
curl --interface 192.168.50.10 http://10.10.50.1:8080/myhostedapp.
For 10.10.50.1 to reach 192.168.50.10, I added it to the route table.
What do I need to configure so that 10.10.50.1 is reachable from 192.168.50.10?
You have to set iptunnel you can see this link it would make it more clear, one more thing when you added route you added the route with a gateway.

First off, you shouldn't use ifconfig anymore. It is unmaintained since 10 years or so and known to have some issues, esp. regarding "virtual interfaces".
Better use ip from the iproute2 package.
See also this articles about ifconfig vs. ip and what the replacement commands look like:
Deprecated Linux networking commands and their replacements

ifconfig sucks
Now regarding your issue: what does your routing table look like? Please provide the output of ip address show eth0 and ip route show. I suspect your routing table to be the culprit.
