[SOLVED] USB Tethering from Android to Arch issue

niezniszczalny · 2017-04-30 19:59:04

I connected few smartphones to my laptop (HP Probook 650) via USB. Activated USB tethering and in any case my laptop didn't see the network (I'm using Network Manager). Tethering didn't work with any of them.

I tried to manually set up connection, so...

I switched off wireless using the hardware key on laptop.
I connected phone & activated tethering.

Then I type

$ ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp0s25: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN mode DEFAULT group default qlen 1000
    link/ether 48:0f:cf:23:0a:fd brd ff:ff:ff:ff:ff:ff
3: wlo1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DORMANT group default qlen 1000
    link/ether 7c:5c:f8:a5:f8:f2 brd ff:ff:ff:ff:ff:ff
39: tun0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UNKNOWN mode DEFAULT group default qlen 100
    link/none

I think that enp0s25 should be my USB port.
Then I type 'ip link set enp0s25 up' and nothing happens.
State is still 'DOWN'.

When I don't have any phone plugged 'ip link' gives me same output as above. I think there's something with those USB ports going on.

$ lsusb

Laptop recognizes phone with tethering on.
What can I do to investigate and solve this problem?

enp0s25 is your ethernet interface.

Edit:
Try with tun0:

Why is there a tun0 device and did you follow https://wiki.archlinux.org/index.php/Android_tethering an which approach did you take?

I'm using Network Manager

In order to effectively do anything with the network devices by hand, first ensure to stop the networkmanager service!

Can transfer files with the (Android) phone?
Have you MTP? packages like: libmtp, gvfs-mtp (for filemanagers that use gvfs)

Edit:
Tested and is not MTP.

tun0 looks like a tunnel for a VPN.

Testing my movil, when connecting by USB it shows up several options; for me works (translated): Network Anchor

What is the output of ip link when the phone is not attached?
Anything interesting added to the journal when the phone is tethered?

Yes. AziLink uses a VPN, that's why I asked ;-)

I didn't know that.

Testing with my phone, if it was connected for charging or transfer with MTP, ip link doesn't show the interface.

What happens if, when the device is shown, you just run dhcpcd as root ?

tun0 device is a VPN I'm using in laptop. When I'm not connected to the Internet tun0 disappears.
I've stopped NetworkManager.service but I still cannot tether via USB using ip link and dhcpcd. I just use pure USB tethering, without AziLink or EasyTether.

I've got those packages. I can transfer files between phone & laptop.

ip link stays the same whenever I attach or detach phone. I think the issue might be that it doesn't recognize the phone/tethering connection.

Journalctl - 02:41:02 I attach plug phone, 02:41:09 I activate tethering.

journalctl -f

[edit]
I remember I was using USB tethering when I was installing Arch few months ago, it was super easy to set up but I don't know exactly how I did it.

Yeah, I'd expect that. The problem is that your phone is not being detected as a NIC. Have you ever used this phone in a USB tethered mode successfully with other hosts?
What gets added to the journal when you attach it the phone? When you enable tethering?
Edit: I missed most of your pot. Sorry.

Edit 2: Sanity check. What are the output of uname -a and of pacman -Q Linux (assuming you are using the stock kernel)

There's your problem. The kernel you are running is not the kernel that is installed. The running kernel cannot find the loadable modules it needs as they were replaced by those for the newer kernel.

Have you rebooted since the last time you updated your kernel?
If so, this can happen if you had updated your kernel when your boot partition was not mounted on /boot. Is the boot partition currently mounted on /boot?

niezniszczalny · 2017-05-01 03:44:08

I've been only hibernating since like two weeks so that may be the cause why my kernel is not updated. I've just restarted laptop, kernel updated automatically. USB Tethering works out of the box, I've got new entry in ip link.

Is there any way to update kernel without restarting laptop? I just love having my session open with everything opened as I closed it before, it saves a lot of time and asspain, otherwise I have to reopen my work environment from scratch.

seth · 2017-05-01 05:37:55

https://wiki.archlinux.org/index.php/Kexec and you don't want to do that. You want to store your session and reboot. Far less hassle.
