Linux Rsync Backup

2009-12-27T17:50:03Z

Mnp: /* Instructions */

Here is a first cut at a backup script which will pull from a linux host. It will create an SSH public key pair if none exists already, copy them to the Pre, then perform a complete rsync to the user's ~/palm directory. So far it works okay with the emulator. Feel free to fix bugs here, or on the discussion tab.

'''Warning''' - Setting up a key pair in this manner will mean a user on your linux box can get your Pre as well.

== Instructions ==
* Make sure you have rsync and openssh installed on your Linux box.
* Save the code below to a file on your linux box (eg, '''backup''').
* Make it executable (eg, '''chmod a+x backup'''.
* Enable wifi on your Pre (you'll need its current IP address), or start your emulator.
* You'll need to know how to ssh as root to your pre with a password. You can set this up temporarily:
ssh -p222 your_user@pre_ip_address
sudo bash -- give your user password, then you're root
/usr/sbin/rootfs_open -w
passwd root
mount -o remount,ro /
exit

* To use the script with your emulator:

linuxbox$ ./backup localhost 5522 root
found, using it
reached the palm with ssh key
receiving file list ... done
./
bin/
... etc ...

* To run with the Pre over IP:

linuxbox$ ./backup 111.222.233.244 222 root

Note you may need to specify the user you created when you rooted the Pre instead. The user will need read access to the whole file tree.

== Code ==
<pre>
#!/bin/bash

die()
{
echo $@
exit 1;
}

[ $# -eq 3 ] || die "Usage: $0 palm_ip palm_port palm_user"
host=$1
port=$2
user=$3

strict='-o StrictHostKeyChecking=no'
pubkey='-o PreferredAuthentications=publickey'
dest="-p $port $user@$host"

[ -x /usr/bin/rsync ] || die no rsync, you should: sudo apt-get install rsync

if [[ ! -f ~/.ssh/id_dsa || ! -f ~/.ssh/id_dsa.pub ]]; then
echo we need to make an ssh keypair
ssh-keygen -q -t dsa -f ~/.ssh/id_dsa -N '' || die ssh-keygen failed
else
echo found, using it
fi

if ssh $strict $pubkey $dest ls /etc/palm > /dev/null; then
echo reached the palm with ssh key
else
echo need to copy local pubkey to palm
cmd='umask 077; test -d .ssh || mkdir .ssh ; cat >> .ssh/authorized_keys'
cat ~/.ssh/id_dsa.pub | ssh $strict $dest $cmd

if ssh $strict $pubkey $dest ls /etc/palm > /dev/null; then
echo second try good, reached the palm with ssh key
else
die could not use pubkey after installing it on the palm
fi
fi

rsync -avz --size-only --exclude proc/ --exclude dev/ --exclude sys/ \
-e "ssh -p $port $strict" $user@$host:/ ~/palm

Can't make heads of this in 1.2.1: the lines indicated do not make sense to comment out. Anybody have an update? Thanks.

Now in /usr/palm/applications/com.palm.app.messaging/app/controllers/chatview-assistant.js Comment out lines 246 and 247 (WebOS 1.1: Lines 289 & 290). This will make it so if you back gesture in a chat, then it doesn't bring you back to the conversation list or do anything else.
