[Q] spending lots of time with segmentation fault error (chroot) - Android Software/Hacking General [Developers Only]

spending lots of time with segmentation fault error (chroot)
I success to open up ubuntu GUI on my android
with following site
(first googled site with "cyanogenmod ubuntu")
but fail with other imgs(such as img in nexusonehack)
for now, I am trying to bootup ubuntu 10.10 on my gw620(smart phone whose cpu is ARMv6 Qualcomm MSM7200)
by my self.
with selfmade rootstock img and busybox and chroot
I made img my self withroot stock with following option
rootstock -f kty1104-Notebook -l kty1104 -p 1 --imagesize 2047M --notarball --seed linux-image-omap,lxde,build-essential,openssh-server,tightvncserver,x11-xserver-utils
and change name to ubuntu.img and place to /sdcard/
and apply to bootubuntu.sh
bootubuntu.sh contents is this

do I need more option for rootstock?
or do I need special sh file for it?
I can mount ubuntu.img with
# mknod -m640 /dev/loop0 b 7 8
losetup /dev/loop0 /sdcard/ubuntu.img
mount -t ext2 /dev/loop0 /mnt/ubuntu
but when it comes to chroot, it sprit [1] segmentation fault chroot ${mnt} /b...#
if there are missing information please let me know, I will write it down

I know I musn't revive old threads... but the question and the problem is already set up here.
I'm having the same problem with my HTC Magic 32A. Anybody knows what's up with the segfault?
Thanks!

I've spent a lot of time on this issue too, and as far as I can tell it's because Ubuntu versions over 9.04 (jerking jackalope or whatever idiot name they use) no longer support ARMv6. This means I can't run BT5, which is based on 10.x, but I believe Debian still supports v6.

Debian in Haykuro/Cupcake builds

Hello all,

I was hoping someone could help me out with this. I would really appreciate it. I am running 5.0.1G (Haykuro's build). I have tried asking him, but neither of us have the knowledge of how to fix the problems.
Thanks.

Check the first lines in the script that begin with "export..." .
For example if your debian image is located like defined in "export kit..."
Or if the binary paths are all correct. I think the problem is that there is probably no /system/xbin within your image like in the JF image. So the script can't find the tools it needs.
EDIT//
You can probably ignore the above part....
The problem is that the script doesn't load the "ext2" filesystem kernelmodule which is needed to mount Debian.
But i don't know if the script only look at the wrong place or if the ext2.ko module isn't available within your image.
You can search for the module by typing the following into a terminal:
find / -name "ext2.ko"

check if /data/local/mnt exists, if not , mkdir /data/local/mnt.

xbin is there. There is no need for ext2.ko because it is built into the kernel already (asked haykuro himself). /data/local/mnt exists. The export statement is right, my debian image is in /sdcard/debian.img.
Any other ideas?
I am running haykuro's 4.5g build. The latest one.

..... is right, my debian image is in /sdcard/debian.img.

Mhm. But that would be wrong...
Has to be in /sdcard/debian/debian.img
So try to create debian subfolder.

Okay, my bad. It's in /sdcard/debian/debian.img.
Any ideas?

I will try to help with this in a few hours. I have the 5.0.2Hr2-appstosd-signed image on my phone, a 1.2 GB ext2 filesystem partition on my SD Card (only a Class-4, it's really dog slow for most apps!), and I am working on getting debian functional within /system/sd.
I don't like the idea of having 3 "different" filesystems on my SD card, so I wanted to utilize the ext2 partition I use for apps/cache for Debian also, this would ensure that I could leave it mounted all the time without worrying about Debian dying if I mount the FAT32 partition onto my computer.

I would really appreciate that. I was thinking the same thing, but I don't know how to do it.

Well that got nowhere quick. Any other ideas?

modprobe ext2
ok i just tried that, that was the solution previously when running debian, yu had to load the ext2 module, but something must be missing in the new build as i get
cannot parse modules.dep

Got the same error
I receive the same error message. Found a solution at the bottom of the first post:

Setup Ubuntu Maveric with 3G Image It Works Running 2 Operating systems simultaneousl

UPDATE: 01/13/11 Scrap Most of this,
got a 3G working image works 10tmes better than anything i have seen.
UPDATE go here:http://forum.xda-developers.com/showthread.php?t=912544
have networking with hamachi, ssh works coolstuff:
trying to put it together (steps to create, and emulate on your computer, an image to get worken on your phone,) it works for the epic also which i have to say i prefer because of the slide-out, ya no wat. as soon as possible 2 DAYS TOPS
To Install Ubuntu Maveric on your Phone:
Of course you must have a rooted phone, since your rom must use a kernel with Loop support, I have only tested this on CyanogenMod Nightly build 199
make sure you have busybox installed
To create the image You have to start with a computer running Ubuntu or setup Virtual Box on a Windows computer,
or go here http://w3.impa.br/~gabrield/data/ubuntu-arm-development-rootfs.tar.bz2 to download the prebuilt one ( i havnt tested it)
1: Open Terminal in Ubuntu
2: Enter:
sudo apt-get install rootstock. After installing Rootstock, again in ubuntu terminal,
Enter,
3: sudo rootstock --fqdn ubuntu --login ubuntu --password ubuntu --imagesize 2G --notarball .
You can change login and password to your desire and also change imagesize 1G 2G and soforth
Your ubuntu-arm.img will be created in about 15 min or so. Take that arm.img and use Ark to crush it down to under 200meg if you would like or and or change name to ubuntu.img.
Using file manager, Create a folder (on your phone) /sdcard/ubuntu
and transfer ubuntu.img to your sdcard folder, ubuntu.
Copy the following text including the (#) and paste into notepad++
(get it http://notepad-plus-plus.org/download) or in linux gedit or Eqvlnt.
Save as sdcard/ubuntu/bootubuntu (no extension)nothing more.
#modprobe ext2

Next update: How to network with Hamachi
It does work

ill give this a try tommorow..

Gonna, maybe, dive in.

Fire up an ubuntu image and then connect to it with vnc... I think I'll wait for the movie to come out and save the battery life. Hey wait, thats an idea. We could make a video of someone using ubuntu, and then play it on our phone so it feels like ubuntu. Might even do better on the battery life / "useful" factor.
(I've seen this method before, so keep in mind I am poking fun at the people who would want to do this and not you for sharing this with us.)

UPDATE:

THIS IS GREAT YAHOOOO
Hi i was hoping you could help me with this problem:
I am using (on a dedicated ubuntu computer with Maverick edition)"https://wiki.ubuntu.com/ARM/RootfsFromScratch" example to create a qemu image using "sudo rootstock --fqdn ubuntu --login ubuntu --password ubuntu --seed nano --notarball --imagesize 3G".
I have also used the "sudo project-rootstock/rootstock --fqdn ubuntu --login ubuntu --password ubuntu --seed nano --notarball --imagesize 3G"
and: "sudo ./rootstock --fqdn ubuntu --login ubuntu --password ubuntu --seed nano --notarball --imagesize 3G" way.
They all work great. I am able to load the image with qemu, got ssh setup and working alls great in life.
The problem lies HERE.......
I am using these images (mostly for fun), to setup ubuntu onto my Evo and Epic smartphones using this method: "http://forum.xda-developers.com/showthread.php?t=881401" to chroot the image.
ITS AWSOME IT WORKS AND LOTS OF FUN!
well sorry for screaming but it really excites me this open source Ubuntu Stuff. (i am a win user, but I found a new toy)
Using the prebuilt image everything works excellent (except for the small image size 2G) that is why i need to use my 3G built image.
My problem: My built image works flawlessly as well, with one exception, (that i have noticed) is, inside ubuntu (on my phone chrooted with android) the terminals do not have a prompt# only black, square curser, and will not except input. I have to use the terminal program inside android to apt-get and such.
I have noticed with my build images, using apt-get during install, i see "Can not write log, openpty() failed (/dev/pts not mounted?)"
error. My reserch says terminals wont work if system cannot write to /dev/pts.
The prebuilt image does not have this issue.
What is the differance with the prebuilt that is offered here "wget -c http://w3.impa.br/~gabrield/data/ubuntu-arm-development-rootfs.tar.bz2", and the images I create using the steps outlined in the article.
Is there modifications prior to or after creation, or is this someting different altogether.
I really have been pulling the little bit of hair i have left out of my head for a week now
HELP.!!!
p.s. I have tried all builds etc; karmic,lucid same results
Try mounting dev/pts says it is mounted but busy

To Homefix :
Did you try "sudo apt-get install ..." ?
To change bash prompt did you try "export PS1=#" ?
What is an output of "id" command? If you get anything other than root, add that user to root group, or just "su" maybe?

Can someone please post some pics or a video of this working?

Revised Ubuntu Installation Created By Homefix and RooferDave
I just put this together today, gotta get back to work, the snowstorms over (im from western NY) might be errors will edit and update as time permits
all scripts contain original authors and credits where aplicable.This tutorial will show you how to create a Debian Image, Emulate that image using The Qemu Emulator in Ubuntu.And finally setup that image on your EVO
I cannot be held responsible if your foolish enough to do, what is outlined below!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I will take the time to post the credits soon.
However the scripts speak for themselves and the creators have left there info in them.
Thanks really goes out to them.
Most of this came from here: https://wiki.edubuntu.org/ARM/BuildArmPackages
Things you need:
# I hope you have the EVO (last i heard radio shack may have 1 left. DRIVE CAREFULLY, theres snow everywere).
# Computer BestBuy ? I prefer to build my own (Brite Computers Fishers NY).and a small note, you need ubuntu ruuning do do any of the image creation-manipulation.
I wasnt able to get VBOX to emulate the Image so... UPDATE yes i was able to get it working i was having a router issue.So give VBOX a try http://www.virtualbox.org/wiki/Downloads
you can either try to get it to work with VBOX,(goodluck), or dust off one of your old computers and get Ubuntu up.
But you may have to do what i did, i yanked out the family computer from the living room and fit in my literally 4' x 7' office to get this done.
i dont worry to much, i know they love me for spending the last 2 weeks with my face attached to the monitor.

Setup Rootstock IN THE BEGINING
In your Ubuntu terminal type: "mkdir /<your home directory>/qemuArm"
(dont includ the < >'s or the ""'s) your home directory usually is /home/<your user name>/
then: cd /<your home directory>/qemuArm
then: sudo apt-get install qemu qemu-kvm-extras
then: sudo apt-get install debootstrap (if you dont have it already)
then: sudo apt-get install fakeroot (if you dont have it already)
then: sudo apt-get install bzr (if you dont have it already)
then: (download rootstock bzr branch)
sudo bzr branch lp:roject-rootstock
then: (download kernel to /<your home directory>/qemuArm) just
make sure you dont leave the, /<your home directory>/qemuArm directoryCREATION
then: (create your image)
sudo project-rootstock/rootstock --fqdn ubuntu --login ubuntu --password ubuntu --notarball --imagesize 3G --seed nano
or: custimize your image with the info in the readme file, in the /<your home directory>/qemuArm/project-rootstockfolder(when your image is complete)
then: (make a copy)
cp qemu-armel-<replace with your #>.img <whatever you name it>.img (remove the <>'s)EMULATION
Download the http://ports.ubuntu.com/ubuntu-ports/dists/lucid/main/installer-armel/current/images/versatile/netboot/ to ~/qemuArm
USE THIS WEBPAGE AND FIND THE LINK FOR YOUR KERNEL VERSATILE
https://wiki.edubuntu.org/ARM/BuildArmPackages
Then: (start your emulation) -----> dont forget to remove the <>'s <------
sudo qemu-system-arm -M versatilepb -cpu cortex-a8 -kernel ./vmlinuz -hda <whatever you name it>.img -m 256 -append "root=/dev/sda mem=256M devtmpfs.mount=0 rw"
then: (hopefully you will see a blank screen)
press alt-F1 if you do not see a login prompt go back to the beginingSO LET THER BE LIGHT
then: log in
then: (to change password)
sudo tmppwd ubuntu and to change login name never do "usermod -l newname -m -d /home/newname oldname" pic the right name at creation.
then: sudo tmppwd root (if you want to set root password) THEN THERE WERE TWO
In the Emulated terminal:
(configure network connections)sudo nano /etc/network/interfaces
add: (under existing entries of the file):
auto eth0
iface eth0 inet dhcp then cntrl-X, confirm save, and exit.
then sudo ifconfig eth0 up
then sudo dhclient eth0
then sudo apt-get update (if it aint broke dont fix it) otherwise go back to the beginningBORN AGAIN
On the Host System make sure Qemu is not running.
then: (install some more stuff)
sudo apt-get install bridge-utils
This assumes if you have a basic networking system with eht0 as interface
then: (configure network bridge)
sudo nano /etc/network/interfaces

then: (Load the tun module (you can add tun to /etc/modules if you want it to load on boot)
sudo modprobe tun
then: set permissions
sudo chmod 0666 /dev/net/tun
then: (change Qemu Script)

[Tutorial] Ubuntu on Epic ? Not Again! no wait, this is different

UPDATE GO HERE:
http://forum.xda-developers.com/showthread.php?p=10972597#post10972597
Revised Ubuntu Installation Created By Homefix and RooferDave
This tutorial will show you how to create a Debian Image, Emulate that image using The Qemu Emulator in Ubuntu.And finally setup that image on your EPIC
I just put this together yesterday, its from my EVO post: http://forum.xda-developers.com/showthread.php?t=881401 .gotta get back to work, the snowstorms over (im from western NY) might be errors will edit and update as time permits
This is made for the epic, but i will try to catch all the changes, i think i got most of em.
Listen up you knuckles, on the evo i can ssh, setup and use samba shares(using hamachi network for connectability), nautilus-shares works, programs dont close, cpu meter works, it truly is like a mini computer in your pocket.
I hope with CyanogenMod i can have the same results because obviosly the epic exceeds the evo because of the keyboard (for this kind of stuff). It sucks to loose half your screen to the input method (with the evo), But i wish the screensize was larger.
For now until there are some kernel changes(hamachi does not work) I have to spend my time playing with that.(Hamachi works in the Evo
However ubuntu seems to run better on the evo
UPDATE cant get Hamachi installed gotta wait for kernel changes -
I guess you can never have the best of both worlds
all scripts contain original authors and credits where aplicable.
I cannot be held responsible if your foolish enough to do, what is outlined below!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I will take the time to post the credits soon.
However the scripts speak for themselves and the creators have left there info in them.
Thanks really goes out to them.
Most of this came from here: https://wiki.edubuntu.org/ARM/BuildArmPackages
Things you need:
# I hope you have the Epic (last i heard radio shack may have 1 left. DRIVE CAREFULLY, theres snow everywere).
# Computer maybe , BestBuy ? I prefer to build my own (Brite Computers Fishers NY).
and a small note, you need ubuntu ruuning do do any of the image creation-manipulation.
I wasnt able to get VBOX to emulate the Image so...
you can either try to get it to work with VBOX,(goodluck), or dust off one of your old computers and get Ubuntu up.
UPDATE: got VBOX working was router issue. so give it a try.
But you may have to do what i did, i yanked out the family computer from the living room and fit in my literally 4' x 7' office to get this done.
i dont worry to much, i know they love me for spending the last 2 weeks with my face attached to the monitor.
# Rom: CyanogenMod-6. You could try others. (i tell my daughter who always copies her sister "you are your own nucklehead").

sorry im late, having trouble upload (free account). this is for the evo. let me know if you can create new files on your desktop, if not you will have to wait until i foward the epic image.
Setup Rootstock
IN THE BEGINING
In your Ubuntu terminal type: "mkdir /<your home directory>/qemuArm"
(dont includ the < >'s or the ""'s) your home directory usually is /home/<your user name>/
then: cd /<your home directory>/qemuArm
then: sudo apt-get install qemu qemu-kvm-extras
then: sudo apt-get install debootstrap (if you dont have it already)
then: sudo apt-get install fakeroot (if you dont have it already)
then: sudo apt-get install bzr (if you dont have it already)
then: (download rootstock bzr branch)
sudo bzr branch lproject-rootstock
then: (download kernel to /<your home directory>/qemuArm) just
make sure you dont leave the, /<your home directory>/qemuArm directory
CREATION
then: (create your image)
sudo project-rootstock/rootstock --fqdn ubuntu --login ubuntu --password ubuntu --notarball --imagesize 3G --seed nano
or: custimize your image with the info in the readme file, in the /<your home directory>/qemuArm/project-rootstockfolder
(when your image is complete)
then: (make a copy)
cp qemu-armel-<replace with your #>.img <whatever you name it>.img (remove the <>'s)
EMULATION
1.Download the http://ports.ubuntu.com/ubuntu-port...aller-armel/current/images/versatile/netboot/ to ~/qemuArm
USE THIS WEBPAGE AND FIND THE LINK FOR YOUR KERNEL VERSATILE
https://wiki.edubuntu.org/ARM/BuildArmPackages
Then: (start your emulation) -----> dont forget to remove the <>'s <------
sudo qemu-system-arm -M versatilepb -cpu cortex-a8 -kernel ./vmlinuz -hda <whatever you name it>.img -m 256 -append "root=/dev/sda mem=256M devtmpfs.mount=0 rw"
then: (hopefully you will see a blank screen)
press alt-F1 if you do not see a login prompt go back to the begining
SO LET THER BE LIGHT
then: log in
then: (to change password)
sudo tmppwd ubuntu and to change login name never do "usermod -l newname -m -d /home/newname oldname" pic the right name at creation.
then: sudo tmppwd root (if you want to set root password)
THEN THERE WERE TWO
In the Emulated terminal:
(configure network connections)
sudo nano /etc/network/interfaces
add: (under existing entries of the file):
auto eth0
iface eth0 inet dhcp
then cntrl-X, confirm save, and exit.
then sudo ifconfig eth0 up
then sudo dhclient eth0
then sudo apt-get update (if it aint broke dont fix it) otherwise go back to the beginning
BORN AGAIN
On the Host System make sure Qemu is not running.
then: (install some more stuff)
sudo apt-get install bridge-utils
This assumes if you have a basic networking system with eht0 as interface
then: (configure network bridge)
•sudo nano /etc/network/interfaces
add: (under existing entries of the file)
auto br0
iface br0 inet dhcp
bridge_ports eth0
bridge_maxwait 0
then: cntrl-X, confirm save, and exit.
then: sudo ifconfig eth0 0.0.0.0
then: sudo ifup br0
then: (Load the tun module (you can add tun to /etc/modules if you want it to load on boot)
sudo modprobe tun
then: set permissions
sudo chmod 0666 /dev/net/tun
then: (change Qemu Script)
sudo nano /etc/qemu-ifup
add: a "#" symbol to all existing entries except the first line (got it?)
add: (under existing entries of the file):
echo "Executing /etc/qemu-ifup"
echo "Bringing up $1 for bridged mode..."
sudo /sbin/ifconfig $1 0.0.0.0 promisc up
echo "Adding $1 to br0..."
sudo /usr/sbin/brctl addif br0 $1
sleep 2
then: set permissions
sudo chmod +x /etc/qemu-ifup
then: start emulation
sudo qemu-system-arm -M versatilepb -cpu cortex-a8 -kernel ./vmlinuz -hda <whatever you name it>.img -m 256 -append "root=/dev/sda mem=256M devtmpfs.mount=0 rw" -net nic -net tap
then: login
then: sudo apt-get install openssh-server
if: that goes well, your home free (we'll discuss errors later)
LEARN TO TALK
Now: you can ssh into or scp to your ARM VM from the host.
get ip address to ssh into or scp to, by simply running ifconfig in the ARM terminal.
install your applications
Or just get right to it and see what this is all about
LEARN TO WALK
Now: we will setup the chroot
Change your imagename to ubuntu.img
Using file manager, Create a folder (on your phone) /sdcard/ubuntu,
and transfer ubuntu.img to your sdcard folder, ubuntu.
Copy the following text including the (#) and paste into notepad++
(get it http://notepad-plus-plus.org/download) or in linux gedit or Eqvlnt.
Save as sdcard/ubuntu/bootubuntu (no extension)nothing more.

NICE
A very nice tutorial, TY for the attention to details.

[ARMv7/Intel][Root][Busybox][init.d]Optware-ng: install pre-compiled native packages

This how-to describes how to bootstrap and configure Optware-ng. Optware-ng is my Optware firmware-independent fork. This allows to install numerous pre-compiled packages.
Lists of available packages can be found here:
ARMv7 hardfloat
Intel
ARMv7 softfloat
And the project home is currently here:
https://github.com/alllexx88/Optware-ng
Some packages may not work, since not all of them are compatible with android, but most will. There're some pre-requisites you must satisfy before you can proceed:
1. You must be rooted
2. Optware-ng relies on some standard linux commands, the easiest way to make sure you have them is to install Busybox with all the links
3. We'll create Optware-ng initialization script in /system/etc/init.d, so init.d support is needed. If you don't have it, you can either add it (google for how-tos on doing this) or edit your init.rc android startup script to include Optware-ng initialization lines (though adding init.d support is still a better idea)
The following commands should be issued from terminal as root. I suggest you use some SSH server available on the Play Store, and connect via SSH from you PC.
1. This prepares needed environment:
- Optware-ng will be installed to /data/Optware-ng with /opt symlinked to it
- Optware-ng scripts rely on /bin/sh, so we symlink it to /system/bin/sh
- Optware-ng needs /tmp temp dir: we create 64Mb RAM disk there (you may adjust the size if you like)
Code:
mkdir -p /data/Optware-ng
mount -o remount,rw /
ln -s /data/Optware-ng /opt
mkdir /bin
ln -s /system/bin/sh /bin/sh
mkdir /tmp
chmod 777 /tmp
mount -t tmpfs -o size=64M tmpfs /tmp
mount -o remount,ro /
export PATH=$PATH:/opt/bin:/opt/sbin
2. This bootstraps the feed:
2.a) for ARMv7 hardfloat (most modern android devices):
Code:
cd /tmp
wget http://optware-ng.zyxmon.org/buildroot-armeabihf/buildroot-armeabihf-bootstrap.sh
sh buildroot-armeabihf-bootstrap.sh
2.b) for Intel:
Code:
cd /tmp
wget http://optware-ng.zyxmon.org/buildroot-i686/buildroot-i686-bootstrap.sh
sh buildroot-i686-bootstrap.sh
2.c) for the unlikely case where your device is ARMv7, but lacks FPU (softfloat feed):
Code:
cd /tmp
wget http://optware-ng.zyxmon.org/buildroot-armeabi-ng/buildroot-armeabi-ng-bootstrap.sh
sh buildroot-armeabi-ng-bootstrap.sh
Unless you're using ARMv7 softfloat feed, bootstrapping process may appear to be "stuck" on this:
Configuring glibc-locale
Generating locale-archive with default locales ...
Click to expand...
Click to collapse
Don't be frightened: if your device isn't too powerful, it indeed takes a lot of time, but you have to do this just once, so please be patient.
3. Make sure environment needed for Optware-ng is restored after reboots, and also run Optware-ng startup scripts on boot:
Create init.d startup script and make it executable
Code:
mount -o remount,rw /system
echo '#!/system/bin/sh
mount -o remount,rw /
ln -s /data/Optware-ng /opt
mkdir /bin
ln -s /system/bin/sh /bin/sh
mkdir /tmp
chmod 777 /tmp
mount -t tmpfs -o size=64M tmpfs /tmp
mount -o remount,ro /
sleep 2
export PATH=$PATH:/bin:/opt/bin:/opt/sbin
for script in `ls /opt/etc/init.d/S*`; do
$script start
done' > /system/etc/init.d/S99Optware-ng
chmod 755 /system/etc/init.d/S99Optware-ng
mount -o remount,ro /system
Once again, you may adjust this line
Code:
mount -t tmpfs -o size=64M tmpfs /tmp
if you want greater/lesser RAM disk on /tmp
(4.) You're basically done, but I suggest you now install Optware-ng's dropbear-android package to act as an SSH server:
Code:
ipkg update
ipkg install dropbear-android
dropbear configs are stored in /opt/etc/default/dropbear and by default are:
Code:
DROPBEAR_ENABLE=no
DROPBEAR_PORT=2222
DROPBEAR_PASSWORD=password
Run these commands to adjust configs, enable dropbear and start it:
(replace <*> strings with actual desired values)
Code:
sed -i -e '/^DROPBEAR_PORT=/s/=.*/=<YOUR_PORT>/' -e '/^DROPBEAR_PASSWORD=/s/=.*/=<YOUR_PASSWORD>/' -e '/^DROPBEAR_ENABLE=/s/=.*/=yes/' /opt/etc/default/dropbear
/opt/etc/init.d/S51dropbear start
Now you are advised to use dropbear as SSH server to play with Optware-ng: use 'root' user, '<YOUR_PASSWORD>' password and '<YOUR_PORT>' port
For better security you may use public key authorization only: set password to blank and add your public keys to /opt/etc/dropbear/authorized_keys (don't forget to `chmod 600 /opt/etc/dropbear/authorized_keys` after you create it!) and restart dropbear or just reboot.
P.S. I'm not exactly sure that this is the right place to post this, please move it if needed.
