[FreeNX-kNX] Printing problem

[Thilo Uttendorfer]

Hello,

I have some problems with printing to a printer on the client side. On the 
client I have a shared printer that I've configured in the nxclient. First 
try, no success. I did some debugging and it looks like the function 
cmd_node_addprinter in nxnode gets killed at some point. So I patched
/usr/lib/nx/nxnode with a sleep command after the call of the function
cmd_node_addprinter:

        --addprinter)
                cmd_node_addprinter &>/dev/null </dev/null &
                sleep 5
        ;;

The patch is really bad, there should be a better solution. But anyway, now, 
when I start a session on the client, I can see the printer in any 
KDE-printing dialog but I still can't print. There is only one cups process, 
shouldn't there be two? 


Some log files:

#### /var/log/cups/error_log

The expect error is caused by the last line of nxnode-login (expect "NX> 1001 
Bye."), if you remove that line, the error is gone. But that has probably 
nothing to do with printing...

My system setup is as follows:

Server:
- Debian Sarge (I did some tests with Ubuntu Edgy, too)
- freenx 0.6.0

Clients:
- Windows 2000 and XP
- nxclient 2.0.0-98 and 2.1.0-17



Any hint would be appreciated.


Thanks,
