+Multi Sync HowTo 
 
-HAS TO BE WRITTEN
+With KDE-Pim/Pi you can sync several devices 
+"in one go". That means you choose on one device
+(where everything is confgured in the right way)
+"Multiple Sync" and all devices will be synced.
+All devices must be reachable via network.
 
-Sync HowTo Zaurus <-> KDE
+In this HowTo we will give an explicit example what to set up
+and how configure.
 
+We assume, that we have four devices which should be synced:
+A Sharp Zaurus PDA with KDE-Pim/Pi installed..
+A Windows laptop with KDE-Pim/Pi installed.
+A Linux Desktop with KDE installed.
+A Linux Laptop with KDE installed.
 
-This is a
-Sync HowTo Zaurus <-> K-Desktop Environment(KDE)
-using the KDE-Pim/Pi applications 
-KAddressbook/Pi (KA/Pi) and KOrganizer/Pi (KO/Pi)
-on the Zaurus (Z).
+NOTE: Your KDE version must be 3.3.0 or higher for sncing with.
+      Please read KDE Sync HowTo how to update your SuSE 9.1 to KDE 3.3.x
+      (KDE Sync HowTo is available in the help menu of KO/Pi and KA/Pi).
 
-You can now easily sync your Z with the 
-PIM data of the KDE.
-(addressbook and calendar data).
-You need to install the desktop versions 
-of KA/Pi+KO/Pi on the desktop.
-You need KDE version 3.3.0 or higher on your desktop.
-You need KA/Pi+KO/Pi version 1.9.11 or higher on the desktop
-and on the Z.
+The Zaurus is connected to the  Linux Desktop via USB cable.
 
-NOTE: Almost the same procedure will make it possible to
-sync KA/Pi+KO/Pi running on Windows with KDE via network.
+All calendar addressbook data should be synced with the other devices.
+That means in particular, that the calendar/address data of KDE on 
+the Linux laptop and desktop is synced with the other devices.
 
-The setup+sync procedure is:
+First we have to install the needed programs, 
+then we have to configure the programs.

-0) How the syncing works
-*****************************************************
-
-After setting up everything, the following actions will
-be performed when syncing:
-User enables "remote pi-sync" on desktop.
-User chooses "sync with configured desktop profile" on the Z.
-Z sends sync request via network to configured IP/port/password.
-KO/Pi on desktop detects sync request and syncs with KDE (configurable!).
-A window pops up, that KO/Pi on desktop is in "remote syncing mode".
-If a conflict occurs when syncing KO/PI<->KDE on the desktop, 
-automatically the newest entry is choosen.
-(To avoid the need of user interaction)
-KO/Pi on desktop sends synced file to Zaurus.
-KO/Pi on desktop is in "waiting mode" to get synced file back.
-Zaurus is syncing it's own calendar with the received file.
-Here can be some user interaction needed, i.e.
-if the sync profile is configured as
-"ask for every entry on conflict" and a conflict occurs. 
-Zaurus sends back synced file to desktop.
-Syncing on Zaurus is complete now.
-KO/Pi on desktop gets back synced file.
-KO/Pi on desktop removes all entries in its own calendar and
-reloads the synced file.
-KO/Pi on desktop syncs with KDE.
-After syncing  with KDE is finished, KO/Pi closes
-the "remote syncing mode" window and displays 
-a "syncing complete" message in the headline.
-
-The actual syncing KO/Pi on desktop <-> KDE is 
-performed by a small command line tool "kdecaldump", 
-which writes/reads the complete KDE calendar resources to 
-a file/from a file.
-KO/Pi tags changed entries such that an unchanged entry
-is not changed in KDE by kdecaldump. That is important for 
-calendar entries in KDE, stored in a "disconnected IMAP" calendar resource.
-
-
-Same way is KA/Pi working.
-

-Precompiled packages are available for SuSE 9.1.
-Choose on the above download location:
-File: KDE-Pim-Pi-1.9.11-SuSE9.1.i586.rpm
-Download file and install it on console with
-su
-rpm -ihv KDE-Pim-Pi-1.9.11-SuSE9.1.i586.rpm
-(NOTE:update with rpm -Uhv KDE-Pim-Pi-1.9.11-SuSE9.1.i586.rpm)
-NOTE for users of SuSE 9.1:
-You need KDE version 3.3.0 or higher on your desktop.
-Plese make an online update in SuSE (YAST), then update
-your KDE to version 3.3.0 or higher.
-You can find links to updated precompiled versions of KDE 
-for SuSE 9.1 on the SusE web site, 
-a direct link is for example:
-ftp://ftp.gwdg.de/pub/linux/suse/ftp.suse.com/suse/i386/supplementary/KDE/update_for_9.1
-HOWTO UPDATE KDE:
-Download there the packages in "base".
-And the needed package for your language in "internationalization".
-Put all downloaded files in one "installation" directory.
-Open console and go to the downloaded "installation" directory.
-Do there a
-su
-and then perform a test for the update:
-rpm -Uhv --test *.rpm
-
-If no dependencies are shown, you can do the actual update with 
-rpm -Uhv *.rpm
-
-If there are missing dependencies, you can resolve them by
-- download the needed updated KDE package from the 
-    "applications" or from the "development" folder on the server.
-- adding a needed rpm package from the SuSE install DVD
-- remove the package that has dependencies from your "installation" directory.
-
-Do the 
-rpm -Uhv --test *.rpm
-until you get no dependencies and no errors, then do a
-rpm -Uhv *.rpm
-Run
-SuSEconfig
-after installing with rpm is finished.
-Restart KDE.
 
 *****************************************************
-3) Connection your Z to the desktop via network
-   (network connection can be set up via USB cable or (W)Lan
+3) Test Setup
 *****************************************************
 
-a) Connection via network cable/(W)Lan cards
-   Connect your desktop to the network.
-   Set up networking on the Z.
-   Make sure, you can ping the desktop from Z.
-b) Connection via USB cable:(is working for Z 7x0 and Z5500)
-   (i) Open console on desktop and type
-           su
-           tail -f /var/log/messages
-   (ii) Connect your Z with the USB cable to your desktop
-        You should get as output in the above console 
-        something like this:
-        ("BUG" is the name of the desktop computer!)
-            Oct 26 12:49:37 BUG kernel: usb 2-2: new full speed USB device using address 2
-            Oct 26 12:49:37 BUG kernel: usb 2-2: Product: SL-C860
-            Oct 26 12:49:37 BUG kernel: usb 2-2: Manufacturer: Sharp
-            Oct 26 12:49:37 BUG /etc/hotplug/usb.agent[22659]: need a device for this command
-            Oct 26 12:49:43 BUG kernel: usb0: register usbnet at usb-0000:00:1d.0-2, Sharp Zaurus, PXA-2xx based
-            Oct 26 12:49:43 BUG kernel: usbcore: registered new driver usbnet
-        You see in the 5. line ("BUG kernel: usb0: register"), that usb device usb0 is used.
-   (iii) Create a network startup entry in /etc/sysconfig/network
-         Depending of the number X of the used usb device, create a file 
-         /etc/sysconfig/network/ifcfg-usbX
-         (in our case /etc/sysconfig/network/ifcfg-usb0 )
-         with the following content:
-               # usbX config for Zaurus
-               IPADDR='192.168.129.200'
-               NETMASK='255.255.255.0'
-               NETWORK='192.168.129.0'
-               BROADCAST='192.168.129.255'
-               STARTMODE='hotplug'
-   (iv) Disconnect the Z and connect the Z again to the desktop.
-        Now you should be able to ping the Z from the desktop, try in console on desktop:
-        ping 192.168.129.201
-        Now you should be able to ping the desktop from the Z, try in console on Z:
-        ping 192.168.129.200
-
-        Now you will get a network connection automatically, 
-        if you connect your Z to the desktop via the USB cable.
-
-
-In the following, we assume, that 
-the desktop has the IP address:  192.168.129.200
-and that 
-the Z has the IP address:  192.168.129.201
+Choose menu: Synchronize - XP
+Now the Windows laptop should be syncronized.
         
-*****************************************************
-4) Configuring KA/Pi+KO/Pi on Z for Sync
-*****************************************************
-
-Start KO/Pi on the Z.
-Choose Menu: Synchronize - Configure
-Fill in name for "Local device name:", e.g. "Z760"
-Click on "New profile"
-Set name of "Profile:", e.g. "BUG".
-(that is the above name of the desktop computer)
-Choose "Profile kind": Pi-Sync.
-Set "Password for remote access", e.g. "xyz" for
-Calendar and Addressbook.
-Set Remote IP address to 192.168.129.200 for
-Calendar and Addressbook.
-(Note: That is the IP address of the desktop!).
-The "Remote port number" is 9197/9198  for
-Calendar and Addressbook.
-You do not have to change the
-"Remote port number" or any other settings.
-Click "OK" button to save your settings.
-
-Now you have configured KA/Pi+KO/Pi sync on the Z,
-no need to configure anything in KA/Pi.
+Choose menu: Synchronize - Z760
+Now the Zaurus should be syncronized.
 
+Choose menu: Synchronize - BUG 
+Now the Linux laptop (and KDE there) should be syncronized.
 
-*****************************************************
-5) Enable remote sync in KA/Pi+KO/Pi on the desktop
-*****************************************************
+Choose menu: Synchronize - KDE_Desktop
+Now KDE on the Linux desptop (your device you are syncing from) 
+should be syncronized with KO/Pi.
 
-Start KO/Pi on the desktop.
-Do a "test" sync with KDE, choose menu:
-Synchronize - KDE_Desktop
-After syncing, you should have the same data in KDE
-and in KO/Pi.
-NOTE:
-The KO/Pi version 1.9.10 had the bug, that on the first
-sync with KDE, all data in KDE was deleted.
-DO NOT USE VERSION 1.9.10!
-
-The bevaviour on the first sync is
-(in versions >= 1.9.11)
-that no data is deleted, the data in KO/Pi and in 
-KDE is merged into one calendar.
-
-When the first sync was ok, please choose menu:
-Synchronize - Enable Pi-sync
-Fill in the values for port ("9197" in our examle) 
-and for the password ( "xyz" in our example)
-that you did configure on the Z for that computer.
-Enable "Automatically start at application start"
-and "Automatically sync with KDE-Desktop when receiving sync request"
-by checking the two boxes.
-Close KO/Pi.
-
-Configure / test KA/Pi on the desktop in the same way.
-Fill in the right value for the port (9198 in our examle)
-in KA/Pi! 
 
 *****************************************************
-6) Sync
+4) Sync all devices
 *****************************************************
 
-After configuring everything as above, you have to do
-the following, if you want to sync your Zaurus with KDE:
-(It syncs will all resources in KDE, that are not "readonly").
+Choose menu: Synchronize - Multiple Sync
 
-Start KO/Pi on the desktop.
-If Kontact or KOrganizer is running, save the calendar!
-Connect the Z with the USB cable to your desktop.
-(Or to the local network).
-Choose on the Z the menu:
-Syncronize - <your name for the desktop sync profile>
-( that was "BUG" in our example ).
-That's all.
+Watch the devices interchanging the calendar data ...
 
-Do the same with KA/Pi.
+Wait until you get the message in the KO/Pi header:
 
-NOTE:
-If an appointment/addressee is created on the Z, it is added to the
-standard resource in KDE.
-
-If you have todos with subtodos in your calendar, you will get on
-every sync (after you restartet KOrganizer or Kontact in KDE)
-the message "xx items changed on local", where
-xx is greater or equal to the number of todos.
-That behaviour is caused by a bug in KDE.
-(In KDE, everytime a subtodo is loaded, 
-it's "last modified" settings are set to the current time - ouch!)
-I hope I can fix this bug in KDE soon.
+4 profiles synced. Multiple sync complete!
 
+NOTE:
+If you want to test syncing, you may get wrong results, 
+if the clocks of the synced devices have too much difference.
+
+Example: Your clocks have a difference of 2 minutes.
+You sync.
+You edit an appointment on two devices.
+You sync again.
+You should get a conflict - but you do not get it.
+The reason is: On one device the "last modified" 
+datetime entry of the editet appointment is before the
+last sync event datetime on the local device.
+Such that the rule is:
+If you have a clock difference of X seconds, you may get
+wrong results, if you edit the same event within that
+X seconds on two devices.
+Same is valid for creating a new event, of course.
+If creation datetime is before the last sync, it is assumed that there was
+an existing event on the local device and the newly created remote
+event is deleted.
 
 
+*****************************************************
+5) Sync KA/Pi
+*****************************************************
 
+Setup KA/Pi in the same way like KO/Pi.
