[Opensync-users] syncml and o2/genion

[Ben E. H. <bv...@gm...>]

Hi everybody,

my mobile phone company o2 offers a syncml-server. They have a special=20
windows-tool to synchronize which I don't want to use. But they also told m=
e=20
the parameters to access the syncml-server:

Serveradresse, Host Adresse: http://syncml.o2online.de/syncml.osp
Port: 80
Benutzername/Login Name: [mobilenumber]@o2online.de
Passwort: [password at www.o2online.de]
Anwendungen/Datenbankname
Contacts: kontakte
Calender: kalender (bei Sony Ericsson Ger=E4ten: Termine)
Todo: aufgaben
Notes: notizen
Sync-Anfragen erlauben (allow sync-request): yes
Alle Sync-Anfr. Annehmen (accept all sync-request): no
Netzauthentifizierung (network authentification): yes
(Normal PAP)
Protokoll: PDP/DHCP

I tried to sync with the syncml-http-server and kdepim, with the following=
=20
config:

<config>
<username>[my phonenumber]@o2online.de</username>
<password>[my password]</password>
<url>http://syncml.o2online.de/syncml.osp</url>
<port>80</port>
<recvLimit>0</recvLimit>
<maxObjSize>0</maxObjSize>
<usestringtable>0</usestringtable>
<onlyreplace>0</onlyreplace>
<contact_db>kontakte</contact_db>
<calendar_db>Termine</calendar_db>
<note_db>notizen</note_db>
</config>

msynctool returns only the message: Error while synchronizing: Unable to sp=
awn=20
server

Any hint what I can do?

Thanks,

Ben

The port 80 only can be opened for a user with root privileges. You can use=
=20
another port over 1024, p.e. 8080.

Un saludo

This doesn't work (msynctool hangs without giving an error message). Can I use 
another port if the syncml-server tells me to use port 80? Would it be unsafe 
to let users use the port 80?

Greetings,
Ben

Hi there,

I can confirm that it doesn't work for me neither. The service from the
provider works, because using the same settings on the phone itself to sync
to the syncml-server works (this works via UMTS or WLAN on the phone). But
of course it would be cooler, if I could sync this server together in one
go, when I trigger the sync between my PC (evolution-plugin) and the phone
with opensync.

BTW, i don't understand how using port 80 can be only done by root? While
browsing the web, you open a lot of connections with that port - why is it a
problem with opensync? I understand this port to be the port the
syncml-server (being at the providers premises) - or is it the source-port
of the PC, too? The problem is that the provider is using port 80. When I
set the port to something else, as Ben already described, opensync hangs
completely.

Any hints much appreciated.

The last days I tested opensync with version 0.22. First I tested between my
PC and my phone over bluetooth, which works more or less (I'm still fiddling
around and will probably post one or more questions regarding little
problems I still have the next days). I used the evo-plugin and the
syncml-obex-client plugin for that.

Then I saw that there is also a plugin to use syncml over http. I thought
I'll add it as the third member of the sync-group. My phone (Nokia E51) also
has the capability to sync over http directly from the phone (via UMTS or
WLAN). This works fine, so I used the same settings as on the phone. I sync
towards a server from the provider, which enables use of mail/SMS webtools
with acccess to all my contacts, which is neat.

The settings for this third member are:
plugin: syncml-http-server
Serverversion: 1.1
Serveraddress: http://sync.A1.net/
Port: 80
Username: myuser
Password: mypassword

You wrote that it works only with the SVN-version, which I don't have in
place. So it's probably a bad idea to try this again until I have moved to
upcoming version 4. On the other hand, I still don't quite get the thing
with the port - what would be the right setting in this case? I just noticed
there is also a plugin syncml-http-client - i should probably have used this
plugin, right.. :/

BTW, are there plans to add a function --delmember to the msynctool? Because
currently the only way to remove a member is to remove the whole group and
recreate the members.

Best Regards,
airflow

Correct settings for SVN trunk:

plugin: syncml-http-client
Serverversion: 1.1
Serveraddress: http://sync.A1.net/
Username:...
Password:...

The port parameter is some kind of a misunderstanding. If you are a 
server then you must only specify the port. If you are a client then you 
must specify the complete URL. The port parameter in the client config 
was a bug.

Yes, the client plugin is correct choice in your case.

--delmember exists already - at minimum in the svn trunk version. BTW I 
wrote a file for bash completion which shows all options and parameters 
incl. available members and groups ;)

I'm missing the beginning of the conversation. So I can only mention 
that syncml-http-server works only with the newest SVN stuff. Port 8080 
definitely works - except that you run another service on this port.

Ports until port 80 are restricted because they were officially 
associated with services and the idea was and is that only authorized 
persons (usually called administrators known as root) should be able to 
start such services. Therefore normal users without root privileges can 
  only establish servers with port numbers higher than port 1024.

You open web connections as a client. If you start a sniffer like 
wireshark then you can see that the server use port 80 and you use a 
port over 1024. This is basic TCP/IP. If you start syncml-http-server 
then you starts a server and not a client and this is a completely 
different thing.

... I don't understand this ... :(

Please describe clearly what you configured. Example:

1. member: 1
    plugin: syncml-http-server
    params: port 8080

2. member: 2
    plugin: syncml-http-client
    params: url http://my.provider.de/funambol/ds

Again please note, that the whole SyncML over HTTP stuff only works in 
newest SVN releases. Compatibility with some servers is tested and 
phones with SyncML over HTTP clients are rare (except of UIQ).

Best regards
