PfSense 2.4.4-RELEASE-p3 attempting to USB tether

ginjaninja · Nov 12, 2019, 4:59 AM

Hello all,

I've surveyed many helpful posts concerning this issue, but I come with questions on support and if I'm doming something wrong. Here's the details:

Using a Xiaomi Mi 9T on i3 Mobile (i3mobile.us) Tethering and all are included
pfSense installed on Sophos UTM 110/120 box, Americantrends BIOS
Went through and added in if_urndis module from FreeBSD ISO since it wasn't included in the FreeBSD 11.2 64 bit build already installed
I have edited the /boot/loader.conf file to include if_urndis and kldstat shows it running
I am not getting the ue0 interface, tested out both USB ports on pfSense hardware
i'm consoled in so i can see the phone being removed/readded instantly

An ideas or pointers?

Further testing, shows I could use
usbconfig -d ugen2.2 set_config 0
but still no interface. Do i need to manually create the interface?

@ginjaninja said in PfSense 2.4.4-RELEASE-p3 attempting to USB tether:

I have edited the /boot/loader.conf file to include if_urndis

You should put that in /boot/loader.conf.local to avoid it being overwritten. That isn't going to help it recognise the phone though.
Anything logged when you connect the phone? It is trying and failing to use the driver?

ginjaninja · Nov 13, 2019, 12:02 PM

@stephenw10 Thanks for the reply. All dmesg shows is disconnect and connection of the phone. Nothing else error wise unless I should look elsewhere?

stephenw10 · Nov 13, 2019, 2:08 PM

Hmm, nope. It seems like urndis just doesn't see it as an interesting device to attach to. Which is surprising since it clear has an RNDIS Ethernet interface.
Not sure there's much we can do there though. Does it have more than one config index you could try?

Steve

ginjaninja · Nov 13, 2019, 4:21 PM

@stephenw10 thanks again. That sticks it would have been great to use this as a failover. No other config indexes available, but there are Bulk labeled Ethernet interface 1. But no index tied to it.

Is there a supported list of working Android devices or perhaps the version of if_rndis.ko is wrong. I pulled it from the 11.2 64bit freebsd release. I see it running...

stephenw10 · Nov 13, 2019, 9:32 PM

That's the correct version for 2.4.4p3. You could try a 2.5 snapshot and use the module from FreeBSD 12.

Steve

ginjaninja · Nov 14, 2019, 3:36 AM

Thanks i'll give it a shot.

ginjaninja · Nov 14, 2019, 4:42 AM

On the hardware i'm installing this on, I consistently get a fatal tray 12 page fault during USB boot. I've tried all IMG and ISO options apart from serial.. I may have to pull back the attempts for now. Unless you have other options.

stephenw10 · Nov 14, 2019, 2:44 PM

You could install 2.4.4p3 and upgrade if it won't boot the 2.5 installer.

You could try forcing it to boot uefi or not uefi depending what it's booting as now.

@stephenw10 thanks for the suggestion. The hardware I'm using (sophos UTM 110/120) firewall doesn't like PFS 2.5 period. After update I still get the same issue. Thanks, I'll attempt this on my Proxmox virtual environment as well. That's where the production PFS VM sits currently.

stephenw10 · Nov 15, 2019, 2:06 PM

Hmm, curious. I'm not aware of any hardware that won't run 2.5.... yet.

Do you have the backtrace or console output leading up to the panic?
