Changing Static Ip adderess.

Question

I am trying to change the IP address of my Beagle. My google attemps have lead me to modifying the interfaces file using a nano editor.

I have edited the file to

# The primary network interface

auto eth0

iface eth0 inet static

address 192.168.1.80

netmask 255.255.255.0

gateway 192.168.1.1

…

# Ethernet/RNDIS gadget (g_ether)

iface usb0 inet static

address 192.168.7.4

netmask 255.255.255.0

network 192.168.7.0

gateway 192.168.7.1

I was expecting it to change when saved but it is clearly not. It still says 192.168.7.2.

Daniel, do you want to change both the USB address and the Ethernet address? Normally I leave the USB at the default (192.168.7.2). For the Ethernet (your example is 192.168.1.80) you can try a reboot to get the beaglebone to read the interfaces file. Or, I forget exact syntax, but you can do $ sudo ifdown and $ sudo ifup commands (the command stands for "interface up")

Hi Daniel, I don't know the answer, but I'm guessing it is because that's a special interface, it may restrict itself to only certain addresses (despite being configured as a /24 network in the file you're editing). This web page seems to indicate as such too, that another file also may need modifying ( /etc/udev/rules.d) as a result: https://groups.google.com/forum/m/#!msg/beagleboard/g_E8dlp2Q4c/5FJUwgeRpxgJ Usually that interface (i.e. over USB) is only used for initial config, so normally the IP addressing doesn't need changing. But if you do have a reason to change it, then the info at that link may help (I've not tried this).

Hi Clem, I'm not sure this will work. There's an earlier link pasted above, that suggest connman is not used for USB network configuration. Text from there: OK, figured it out. The usb0 interface is not configured using connman like eth0 is. It's configured using udev. This is why I think it's going to by different, or not as straightforward to change it. But also begs the question, why change it, given that for most practical scenarios, it is only used during initial setup. It may need changing if multiple BBBs are being connected to the same PC via USB, I don't know, but that's a not-normal scenario so it would be good to know the reason to want to change the IP addressing.

First need to find your ethernet settings: root@beaglebone:/var/lib/connman# ls -al total 16 drwxr-xr-x 3 root root 4096 Jan 1 2000 . drwxr-xr-x 18 root root 4096 Jan 1 2000 .. drwx------ 2 root root 4096 Jan 1 2000 ethernet_c8a030ab323a_cable -rw------- 1 root root 68 Jan 1 2000 settings root@beaglebone:/var/lib/connman# cd ethernet_c8a030ab323a_cable/ root@beaglebone:/var/lib/connman/ethernet_c8a030ab323a_cable# ls data settings settings.ODU2WW root@beaglebone:/var/lib/connman/ethernet_c8a030ab323a_cable# more settings [ethernet_c8a030ab323a_cable] Name=Wired AutoConnect=true Modified=2000-01-01T01:18:21.869401Z IPv4.method=dhcp IPv4.DHCP.LastAddress=192.168.1.100 IPv6.method=auto IPv6.privacy=disabled So in my case my name is ethernet_c8a030ab323a_cable. Look for /usr/lib/connman/test. In there you can use the script to set the Ethernet static IP using my name from above: ./set-ipv4-method ethernet_c8a030ab323a_cable manual 192.168.1.80 255.255.255.0 192.168.1.1 That should be saved in the connman file above. Hope this helps, Clem
