Can you please describe a bit more exactly what you are doing and what you see? Is your Ubuntu 10.10 the server, or is it the client printing to a Windows native printserver? If it is the server, what is the client operating system you are printing from?

Please provide a network trace of your problem. Information on how to create network traces that are useful to the Samba Team can be found under http://wiki.samba.org/index.php/Capture_Packets

Thanks,

Volker

I'm trying to print from a client with Ubuntu 10.10 to a Windows
native printserver.

I'm sorry, but I'm not sure what I'm suppose to do with this: http://wiki.samba.org/index.php/Capture_Packets. Which "FILENAME" should I use?

thanks.

Just invent a filename, for example /tmp/print.cap

The resulting /tmp/print.cap should be uploaded as an attachment to this bug.

well... all I get was this: 

tshark: There are no interfaces on which a capture can be done
tethereal: comando non trovato ("command not found")
tcpdump: no suitable device found

You need to become super-user via "su -" before starting tcpdump.

With Ubuntu this would be

sudo su -

instead of

su -

Sorry for that confusion.

tcpdump 

:) thanks, 
ok, it's done, but...
Another question: 
    ... for how long should I leave it(tcpdump) running? 
    ...Should I run tshark as a super user too? 

I'm sorry about all the trouble I'm giving you!

How do you exactly print, how can I reproduce this issue?

well, I've installed the latest version of Ubuntu (10.10). Them reinstaled the printers (they use to work just fine with ubuntu 10.04) and now i just can't print anything, not even the printer test page. I always get the same "invalid
SMB signature" error message.
I can see the printers, I can explore the windows share folders but the printers just won't work with my fresh ubuntu install...  

Ok, I've never used the GUI of Ubuntu to print. Sorry, this will take a while until I upgrade to 10.10 to be able to try this.

is it possible to "downgrade" to the previous samba version? would it help? I really need to print...

I tried to print directly to the printer's IP and i had no problems, but i need to print via a windows server 2003 and a O&K print watch... and everything use to work fine with Ubuntu 10.04...   

Ok! downgrading to samba version 3.4.7 solves the problem! back to printing!  

I'm not aware that this is an issue with current versions. Please reopen if this is still an issue with latest supported samba versions.
