obexd: obex_handle_input: poll event HUP ERR

[Jiri Slaby]

Hi,

I have a problem with receiving files with obexd. After it receives
header (file name etc.) it hangs up the connection with
obex_handle_input: poll event HUP ERR

With obex-data-server, everything works as expected.

$ rpm -q obexd libopenobex1 bluez kernel-desktop|sort
bluez-4.64-2.6.x86_64                   == should I try 4.66? ==

libopenobex seems to be indicating REQDONE, so it doesn't look like
anything is necessarily wrong with obexd here. However, you'd need to
look at the HCI level trafic (output of "hcidump -XV") to determine
what's really going on (e.g. is it obexd or the client that's
disconnecting).

So obexd is responding with "forbidden" to the client.
Possible reasons:

* obexd doesn't have write access to the directory it's trying to
  write to

* You don't have an agent registered for obexd that could accept
  the request or you're not running obexd in the auto-accept mode
  (the -a switch).

Yeah, -a solved the problem. What does it mean to have an agent
registered? What is agent?

Thanks.

If you don't want obexd to go blindly accepting files from random remote
devices you'll probably want some sort of user interaction on the server
side, right? One possibility would be to have a GUI process show a
"Accept file from ..." dialog every time there's an incoming request.
You might also want to choose exactly where on the filesystem obexd
stores the incoming file. Such choices would be made by an agent, i.e.
a process separate from obexd that has through D-Bus told obexd that it
can take care of incoming requests. There's an example command line
agent written in python available at test/simple-agent in the obexd
source tree. The actual D-Bus API of an agent is documented in
doc/agent-api.txt in the same source tree.

I have gnome-bluetooth-2.30, but I guess it was not converted to act
also as obexd Agent yet.

gnome-bluetooth doesn't have any Obex server bits. You'd need to use
gnome-user-share to have Obex server capabilities, and it doesn't use
obexd right now, but obex-data-server.

Patches welcome :)

Cheers

Hello,

I have a problem with receiving files with obexd. After it receives

Problem seems to be here, apparently we could not convert the name
received (Unicode length 18 according to hcidump), so the name is not
set cause plugin/ftp.c:268 to fail. Could you please check what is the
string in the header and if that is really a utf16 as the spec
mandates.

obexd[844]: Conversion from character set 'UTF16BE' to 'UTF8' is not supported

As I understood this is a glib problem not obexd. Thanks for your help.

Yep, probably some dependency missing so that it makes glib unable to
do the conversion. Anyway I think I gonna go ahead and add these so
that it is easier to detect such problem in the future.
