[How-to] install Debian and openssh server in T-Mobile G1

Assume you have installed CynogenMod and get busybox in it, you can install Debian system in G1 or other Android phone that has been rooted and have busybox in that custom ROM.

The instruction of setting up debian in G1 is in saurik's site here http://www.saurik.com/id/10
But some of the information are outdated, as the rooting is very simple now and the busybox comes with all custom cooked ROMs.

I like this method as the Debian system is installed in a standalone img file which can be copied to other Android phones.

(1) Download the Debain G1 image here
http://modmygphone.com/files/debian-G1.zip

or
http://rapidshare.com/files/161776007/debian-armel-750.img.bz2

unzip bz2 file with
bunzip2 debian-armel-750.img.bz2

(2) unzip it and copy the img file to sdcard. The image is 750M in size, so make sure you have enough space in sdcard.
adb push debian-armel-750.img /sdcard/kit/

(3) su shell access into G1

adb shell
su


(4) setup mount and chroot

export kit=/sdcard/kit
export mnt=/data/local/mnt
export TERM=linux
export HOME=/root
export PATH=$bin:/usr/bin:/usr/sbin:/bin:$PATH

busybox clear

busybox mkdir -p $mnt

busybox mount -o loop,noatime $kit/debian-armel-750.img $mnt

busybox mount -t devpts devpts $mnt/dev/pts
busybox mount -t proc proc $mnt/proc
busybox mount -t sysfs sysfs $mnt/sys

busybox mkdir -p $mnt/mnt
busybox mkdir -p $mnt/mnt/sdcard $mnt/mnt/system
busybox mkdir -p $mnt/mnt/data $mnt/mnt/dev

busybox mount --bind /sdcard $mnt/mnt/sdcard
busybox mount --bind /system $mnt/mnt/system
busybox mount --bind /data $mnt/mnt/data
busybox mount --bind /dev $mnt/mnt/dev
busybox mount -t tmpfs tmpfs $mnt/tmp -o noatime,mode=1777


busybox chroot $mnt /bin/bash
# now G1 should be in Debian System

rm -f /etc/mtab
ln -s /proc/mounts /etc/mtab


(5) change root password and install OpenSSH and start it

passwd root

apt-get install debian-keyring debian-archive-keyring
apt-get update
apt-get upgrade
apt-get install openssh-server openssh-client
/etc/init.d/ssh start


(6) If the default package source does not work, you can change this file /etc/apt/sources.list to

deb http://ftp.us.debian.org/debian lenny main


(7) if you want to install gcc compiler

apt-get install build-essential


(8) exit the debian system
exit

(9) Before you proceed to copy the Debian system to the /system/sd, please consider to check the partition size of /system/sd first. If you want to manually increase the ext2 partition size, please follow this guide below. Please backup before re-partition as the process will wipe your sdcard data.

http://forum.xda-developers.com/showthread.php?t=534714

This how you can backup the /system/sd and sdcard

adb pull /system/sd/app app
adb pull /system/sd/app-private app-private
adb pull /system/sd/dalvik-cache dalvik-cache
adb pull /sdcard sdcard


and this is how you restore data after repartition the sdcard (remember this is when the phone is booted up and not in recovery mode

adb push app /system/sd/app
adb push app-private /system/sd/app-private
adb push dalvik-cache /system/sd/dalvik-cache
adb push sdcard /sdcard



(10) Reboot G1
reboot

(11) Copy the Debian system to /system/sd if you use CynogenMod ROM and have ext2 partition in the sdcard

cd /data/local/mnt
tar cf - . | (cd /system/sd/; tar xvf -)



(12) create the mount script as /system/sd/userinit.sh

export mnt=/system/sd

export TERM=linux
export HOME=/root

busybox mount -t devpts devpts $mnt/dev/pts
busybox mount -t proc proc $mnt/proc
busybox mount -t sysfs sysfs $mnt/sys

busybox mount --bind /sdcard $mnt/mnt/sdcard
busybox mount --bind /system $mnt/mnt/system
busybox mount --bind /data $mnt/mnt/data
busybox mount --bind /dev $mnt/mnt/dev


append this script if you want to start ssh server automatically
busybox chroot /system/sd /etc/init.d/ssh start

(12) Reboot G1
reboot


(13) Then you can ssh to your G1 by using ssh root@xxx.xxx.xxx.xxx after enable wifi in G1, where xxx.xxx.xxx.xxx is the IP address of G1.


This is how you chroot manually when you use adb shell access
chroot /system/sd /bin/bash

Android NDK Makefile

(1) install NDK 1.6 in say
~/Android/android-ndk-1.6_r1

download http://developer.android.com/sdk/ndk/1.6_r1/index.html

(2) install SDK 1.6 in say
~/Android/android-sdk-linux_x86-1.6_r1

download http://developer.android.com/sdk/1.6_r1/index.html

(3) you can compile standalone C program like this hello.c using the Makefile below

#include <stdio.h>
int main() {
  printf("hello, NDK makefile world\n");
  return 0;
}

Fix SSH timeout for jailbreak iPhone

Login iPhone and edit /etc/ssh/sshd_config and change the line

from

#ClientAliveInterval 0

to

ClientAliveInterval 60

According to man sshd_config, this line,

Sets a timeout interval in seconds after which if no data has been received from the client, sshd(8) will send a message through the encrypted channel to request a response from the client. The default is 0, indicating that these messages will not be sent to the client. This option applies to protocol version 2 only.

Don’t forget to restart sshd on the iPhone after you save the file.
