Ethernet via OTG cable

Hi Group

I will connect my FP2 via LAN, so I take an OTB cable and I connect an USB-Ethernet adapter on it, but nothing happens.

So I dive a bit deeper and I found some information on the dmes output:

[ 3908.852517] usb 2-1: new high-speed USB device number 2 using xhci-hcd
[ 3908.889419] usb 2-1: New USB device found, idVendor=0b95, idProduct=7e2b

[ 3925.244422] eth0: no IPv6 routers present
[ 3926.891636] init: no such service 'dhcpcd_eth0'

So my phone can see the adapter and…

root@FP2:/ # ip a
...
28: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 9c:eb:e8:08:6d:2a brd ff:ff:ff:ff:ff:ff
    inet6 fe80::9eeb:e8ff:fe08:6d2a/64 scope link 
       valid_lft forever preferred_lft forever
root@FP2:/ #

…it maps also a device name, but no ip address is assigned…

255|root@FP2:/ # dhcptool eth0                                                 
root@FP2:/ # ip a
28: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 9c:eb:e8:08:6d:2a brd ff:ff:ff:ff:ff:ff
    inet 192.168.2.209/24 brd 192.168.2.255 scope global eth0
    inet6 fe80::9eeb:e8ff:fe08:6d2a/64 scope link 
       valid_lft forever preferred_lft forever
root@FP2:/ # ip r

192.168.2.0/24 dev eth0  proto kernel  scope link  src 192.168.2.209 
root@FP2:/ #

…now i got it, nice. But I don’t like to have all the time to do this process. Is there anyone around who had solved this?

I try the same on my Acer tablet (Androit 6.0) and it works without root and straight forward.

I’m wondering whether this isn’t to be filed into #software:dev.

@z3ntu is this relevant for the source code?

I’m wondering whether this actually should be “OTG”.

Typo

Thank you

Someone had tried the same in 2016 here and also linked to the XDA site which I think is a very useful and informative site btw.
Maybe you are lucky to find a solution there.
