Im currently Porting Arch Linux to My phone and I am trying to set up the rootfs properly - have it installed to an external scdard and am using busybox to chroot into it with busybox chroot /data/ local/mnt sh I can see pacman exists when I search for it: /usr/bin # type -a pacman returns /sbin/pacman but whenever I try to install the base system with: pacman -S base-devel 1lightdm xorg-xinit xfce4 networkmanager --needed I get sh: pacman: not found

It was empty resolve.conf simlink so I copied /etc/ppp/resolve.conf one and it worked. Anyway **the error still remains** and I would like to get rid of it. Also note that I am doing all with Network Manager service disabled.

I have an extra mobile (one plus 7 pro) lying around, it has really good processor and alot of storage I am thinking of making it *remote server* type something in which I can **ssh** into. Store my files or maybe learn about arm programming One plus 7 pro comes with its propriety flavour of android called oxygen OS, Is there any linux based OS that supports it. I think ubuntu touch may work. But the problem is that most of these opensource OS, do not work on their proprietary hardware. At least not fully Hence I want to be able to move back to Oxyge os, whenever I want. The only option i see is dual boot. But how do I dual boot. In PC you just press the boot key and the boot menu shows up, you can then boot from a pendrive. How does this work in phones

I want to convert some old android phones(2017+) into SSH only servers, is it possible? My objectives are: - run the phones 24/7 without a battery - I don't want to use anything besides the motherboard and the wifi(or if possible to get internet from USB), and scrap display, battery, camera and other sensors for money - bare metal performance, no android junk inside that eats cpu and ram - root access, just like in a server - run ubuntu server or debian The scope of my project is being able to reuse old phones as linux servers and run stuff like nginx, posgresql, nodejs, ruby. And even docker if possible.

I do not like having a mobile cellphone and having to carry it around all the time and do 2FA by SMS, but many services I use require it, as does my school. I also lost my phone and cannot afford a new one at the moment. I do have a SIM card with a mobile plan; is there any way I can get the SMS messages on my PC?

Oukitel WP23Pro specs: https://www.gsmarena.com/oukitel_wp23pro-12650.php This has to be the hardest platform I come across for unlocking bootloader and rooting. 1. There is no downloadable firmware, so I don't know how to extract the boot.img and vbmeta-sign.img from the phone, so I can't unlock the bootloader and install TWRP etc. 2. Looking at the WP23Pro's little brother WP23, which has a downloadable pac images you can flash, extracting boot and vbmeta-sign.img from. You will find Manufacturer used its own OEM key. So I assume it's the same in WP23Pro version two. 3. I have tried every known: fastboot oem unlock, fastboot flashing unlock commands for unlocking the bootloader, inkluderad oem get_identifier_token and using the key in : ./signidentifier_unlockbootloader.sh XXXXXX rsa4096_vbmeta.pem signature.bin, and trying to flash the key: fastboot flashing unlock signature.bin / fastboot flashing unlock_bootloader signature.bin / fastboot flashing --force unlock signature.bin Nothing I do seems to work. So how can I root existing firmware or flash a prerooted GSI?.

Some time ago I installed Termux terminal on my phone just to have some fun with it. Later I discovered I can have an Ubuntu distribution running with it so I decided to give it a try. It's working nicely but all things that need to display something or play some sort of sound do not work. I suppose my Ubuntu is just trying to do the exact thing it would on a PC but things are a little bit diffrent on mobile. I can hovewer play sound and display things when using Termux without Ubuntu so things like VLC work for example. I just wonder if it's possible to fix this issue or develop some workaround.

I'm stuck on a problem using ModemManager (mmcli 1.14.2) to programmatically send SMS which contains a certain combination of special characters which I have yet to identify. The SMS I'm trying to send is the following: OK({ yRgK1DNXQKo4C7uK43WnHArW1XbNekn6JJ80qgMTRcPM8pgGTJMwYDgseRRYOEA6NdCgQNgiSoheRZnK0czZy5P0GTny3rRrSEE9HTiFepFnhDxM6B2J3bpbHnHJiYbSQt40rt0dwIoZYeiEYyo7glw1kswTrg7He5Ojl8ysyxF4X54SCQomZrKRPsrEHpT2vLjCLfGn9pDGHxodwXbbKADm8j4waiGVnZfRBJBDSx8VUO28Yit068aM32t9a91NC0eUVkyUEGkNsm75cVQ7KJ0rpzucTRSudO7DJLxrgetz }) *I'm using a random string here just to simulate a large payload. In reality, the payload between curly braces is a more structured model*. **The problem is that whenever I use the curly braces to encapsulate the payload, the message is not delivered to the recipient.** I'm facing this issue using the following send methods. Using MMCLI ------------ Sending SMS using mmcli with: mmcli -m 1 --messaging-create-sms="number=,text='OK({yRgK1DNXQKo4C7uK43WnHArW1XbNekn6JJ80qgMTRcPM8pgGTJMwYDgseRRYOEA6NdCgQNgiSoheRZnK0czZy5P0GTny3rRrSEE9HTiFepFnhDxM6B2J3bpbHnHJiYbSQt40rt0dwIoZYeiEYyo7glw1kswTrg7He5Ojl8ysyxF4X54SCQomZrKRPsrEHpT2vLjCLfGn9pDGHxodwXbbKADm8j4waiGVnZfRBJBDSx8VUO28Yit068aM32t9a91NC0eUVkyUEGkNsm75cVQ7KJ0rpzucTRSudO7DJLxrgetz})'" and then mmcli -m 1 --sms --send Which gives the following result: > successfully sent the SMS Using DBUS ---------- I use the Messaging DBUS interface to create a new SMS , set its "number" and "text" (UTF8 string) properties and then send it using its Send() method. I use C# and Tmds.Dbus to interact with the bus. ## The problem ## Using both methods, I'm unable to receive the message on the recipient's phone. If I try to send the same message **without** curly braces, it gets delivered without any problme. If I try to send another message **with** curly braces (something like "*OK({Test})*" it still gets delivered without any problem. If I try to send any of the above messages from a phone to the device I'm using (with modem manager) they get received without any problem (with or without curly braces, long and short version). It seems like there's a special combination of chars which causes problem to ModemManager and therefore does not get sent. The fact the same message can be sent from a phone to ModemManager makes me think there isn't any problem on the mobile operator side. Unluckly, since the actual payload contains a JSON encoded model, curly braces are important.

I'm trying to configure a debian 9 device to have cellular failover in case WAN fails (or vice versa). I tried doing this with ifenslave, the failover works in general but it doesn't switch gateways. It keeps the primary one. Here is the config from /etc/network/interfaces (I used the example 3 from here: https://wiki.debian.org/Bonding) : # interfaces(5) file used by ifup(8) and ifdown(8) # Include files from /etc/network/interfaces.d: source-directory /etc/network/interfaces.d auto eth1 lo iface lo inet loopback auto bond0 iface bond0 inet dhcp bond-slaves eth0 eth1 eth2 bond-mode active-backup bond-primary eth0 bond-miimon 100 bond_downdelay 200 bond_updelay 200 allow-bond0 eth0 iface eth0 inet manual allow-bond0 eth1 iface eth1 inet manual allow-bond0 eth2 iface eth2 inet manual iface eth1 inet static address 192.168.4.127 network 192.168.4.0 netmask 255.255.255.0 broadcast 192.168.4.255 gateway 192.168.4.1 I added eth1 as well for general testing. This is the output from ip r before I unplug the cable from eth0: default via 192.168.22.2 dev bond0 10.0.0.0/8 dev eth2 proto kernel scope link src 10.197.68.254 192.168.4.0/24 dev eth1 proto kernel scope link src 192.168.4.127 192.168.22.0/24 dev bond0 proto kernel scope link src 192.168.22.31 And after I unplug the cables: default via 192.168.22.2 dev bond0 10.0.0.0/8 dev eth2 proto kernel scope link src 10.197.68.254 192.168.4.0/24 dev eth1 proto kernel scope link src 192.168.4.127 linkdown 192.168.22.0/24 dev bond0 proto kernel scope link src 192.168.22.31 As you can see, eth0 and the cellular interface eth2 receive different gateways via DHCP. So I can't set static GW for the cellular interface since it might change over time. Why isn't this working properly? Or do you have a better idea how I could configure this?

My ssh sessions are frequently disconnected when I use a provider that offers internet service via cellphone towers. They seem to "freeze" and stop responding to anything I've typed, but sometimes don't give an actual disconnect message until several minutes after they have frozen. I'm answering my own question in "Q&A style" below - this is a problem I've spent the last year trying to work around, and I wanted to consolidate and share all of the solutions I've found so far. (Feel free to add your own answers too if you have other solutions I haven't found yet!)

If I have a mobile app, capable of scanning devices on my LAN, how can I set up my linux machine (to be present as a device on the LAN), lets say a Raspberry Pi, so that the mobile app can help the machine to connect to WiFi. From the machine I can connect to WiFi with nmcli nmcli dev wifi connect password And this gives the machine an IP on the LAN. This is not what I need. I want that when the linux machine is introduced first time in a LAN, without any changes from the machine, I want to connect it to WiFi from my mobile app. An example of this is how Amazon Echo devices connect to Wifi.

I am Running Raspian on a RaspberryPi. When I plug in a GSM modem I see two interfaces - *wwan0* & *ppp0*. - wwan0 exists even when the GSM modem is plugged but not connected - ppp0 exists only when the GSM modem is connected ### Questions 1. What is the difference between wwan0 and ppp0, and why do I see ppp0 in addition to wwan0? 2. Why is the IP address assigned to ppp0 and not wwan0 after a connection is established?

I have a new Samsung Galaxy A40 and would like to use a Linux-based alternative to Android. Reasons: Privacy/security, hackability, moving away from Google. 1.) Can I install an alternative OS even though my device is not explicitly supported? If not, what are the limiting factors? Does each device require a specific set of drivers (e.g. graphics, audio, peripherals)? 2.) Are there any good OS options? Is anyone using Ubuntu Touch? The OS should be safe, stable and user-friendly. Also, using standard device functions and installing/sideloading APKs of standard apps (e.g. WhatsApp/Telegram/KakaoTalk) should be straightforward with no extensive workarounds required. PS.: I have no experience as a mobile developer.

I have an old phone with a telephone card (SIM card) inside. The telephone has an infrared interface on the side. I want to read out my contacts and stored SMS messages from the phone, either via infrared, or by connecting the SIM to the computer by means of some kind of card reader. I once managed to read the data via infrared, but I cannot recreate the needed setup because I have no computer with irda interface anymore. So I've bought a card reader, which unfortunately only works on Windows. The application that comes with it is absolute trash and does not allow saving of data (WTF?!?! Who designed THIS?). Whatever, this reader has a credit-card sized plastic card where you can plug in the SIM card, so I plug the SIM into any kind of card reader. So my question: - How can I get the stored data from the SIM using this Adapter? I have access to a computer that contains an integrated card reader, but I would have to check how to do it beforehand. - If I get hold of an infrared interface somehow, which program is the best choice to read out stored SMS messages and pohonebooks? How is this done? (cmd-lines/link to howto preferred). I hope someone can help, since the phone starts to die, and I want to save all my SMS which don't all fit on the SIM (I would have to copy them from phone memory to the SIM, delete them and copy the next batch, since the SIM can only store 10 messages ...).

I want to have mobile broadband on my T480s. First I ordered the L850-GL which didn't work because it uses the PCI interface. As you can see in this forum. People in the same thread claim to have a working L830-EB on their devices and in this (german) forum someone has managed to use the same module with Kubuntu. I could successfully use the module in a Windows 10 VM. This and the fact that I could not find a "Lenovo Activation App" for my system lets me assume that the activation is successful or not necessary. I tried following this guide but the result is: $ sudo ./qmi_setup.sh start error: couldn't open the QmiDevice: Operation timed out: device is closed your wwan device may be RFKilled?

I have a set of Thinkpad X-series (x86) for a fresh installation of Linux OS. **I want to ask based on today's trend for mobility, such as android, is Gentoo development catching up with today's popularity, if not what would be equivalent to Gentoo?** Looking at Linux Distro from Wikipedia, the timeline based on initial release over 10 years are Slackware, Debian, FreeBSD, Gentoo. But the Gentoo hasn't been growing in its popularity since then. http://en.wikipedia.org/wiki/Linux_distribution The equivalent closest to Gentoo I have seen in Wiki page is Chromium OS, > "designed by Google that primarily runs web applications, using Gentoo > as its foundation." - Wiki However, though, nothing seem to have mentioned in particularly about Gentoo OS in Chromium Website. The relatable term I can see is "Portage", which is Gentoo's Package Manager. http://en.wikipedia.org/wiki/Chromium_OS **My next question is could Chromium OS be the future Gentoo-alike OS based on future key trend of mobility?**

I'm using Huawei E3276 mobile modem for 4G LTE connection with Linux Manjaro XFCE 64bit, works out of the box without driver installs made by user. Problem is that while download is working normally as it should, upload is very slow. While on Windows 7 upload is steady 30-40Mbps depending on day, but on Linux it barely hits 4Mbps. Could it be a driver problem or a bug as a friend of mine suggested? And is it possible to fix it and how? This is as for now only thing for me that is kind of pulling me back to Windows so would love to get this fixed ASAP. Edit 1: While other Linux distros have this upstream throttle, on Linux Mint Debian Edition 201403 upload is working as it should, usually being around 30-45Mbps. Addition: The same symptoms seem to be present in different hardware and Linux distributions: also with Ubuntu 14.04 LTS (64 bit workstation, kernel 3.16) and Raspbian Jessie for Raspberry PI (kernel 3.14). Upstream seems to be always limited to about 5 Mbit/s whenever checking the speed from the Linux computer that is used as an LTE router. The other computers in the LAN always get much more upstream (2 to 3 times as much), even though the traffic is routed through the same Linux computer suffering from seemingly capped uplink. A Windows 7 installation in the same hardware as Ubuntu does not have this uplink limitation. So the problem is not with E3276 device itself or in the mobile subscription, but in the Huawei E3276 Linux compatibility. Maybe something in the kernel? It is not a matter with iptables rules: the speed does not noticeably increase when iptables is disabled. Turning off IPv4 forwarding does not improve speed either.

I have a problem with the WWAN (Qualcomm Gobi 2000) in my Lenovo ThinkPad W510. I can not unlock my SIM card with the correct PIN. I enter the PIN in this dialog and after this I get immediately this dialog After I enter the SIM PIN2 the only thing that happens is that I get a notification that says that the connection is disabled. I know that this is not a problem with the PIN or the SIM card because I checked both with my Windows 8 notebook. What I have to do to use the WWAN in my notebook.
