[FreeNX-kNX] Printer and file sharing via smb

Fri Feb 29 13:33:06 UTC 2008

Hello.

I've read several posts about that, particularly discussions between Fabian 
and Prakash Velayutham.
But I still have problems.

I test FreeNX 0.7.1 on an ubuntu 7.10 with a windows client on Vista.

1) When I want to mount a file share, an error occurs. In fact, I've noticed 
that the line

$(cat 
"$USER_FAKE_HOME/.nx/C-$SERVER_NAME-$display-$sessionid/scripts/mport")

in nxnode, function cmd_node_smbmount, returns nothing. A possible 
workaround is to test if that command returns nothing and, in that case, 
reinitialize port with $(getparam port).

Some people noticed this issue and have proposed a patch. For example, see

http:// 
kambing.ui.edu/gentoo-portage/net-misc/nxserver-freenx/files/nxserver-freenx-0.7.1-samba.patch

2) When I want to attach a printer, at the beginning of the session, I've 
got a dialog box which proposes to choose the driver. If I click on the 
button configure, I've got the login box from the Linux NX client of the 
server. That sounds not logical...

3) The painful issue: in fact I can't print to a shared windows printer.
In node.cfg, SAMBA_MOUNT_SHARE_PROTOCOL="smbfs"

The log on the client is:

On the server, the interesting part is:

NX> 709 File-sharing port: 139
server_nxnode_echo: NX> 709 File-sharing port: 139
NX> 1009 Session status: starting
server_nxnode_echo: NX> 1009 Session status: starting

flevee at 127.0.0.1's password:
NX> 1000 NXNODE - Version 2.1.0-71 OS (GPL)
NX> 1001 Bye.
expect: spawn id exp5 not open
    while executing
"expect "NX> 1001 Bye.""

The error  sent by the command
/usr/sbin/lpadmin -p "$NAME" -E -v "$DEVICE_URI" -m "$MODEL" $PUBLIC
of the function cmd_node_addprintert is, in french:
lpadmin: Impossible de se connecter à "Aucun fichier ou répertoire de ce 
type".

If I try to use lpadmin manually via
/usr/sbin/lpadmin -p HP4100 -E -v smb://admin:*******@127.0.0.1:4001/HP4100
I can't also print and the error on the client side is:
Proxy: PANIC! Can't open a new channel over an existing ID#2 with FD#13.

Another try with smbspool:
    smbspool smb://admin:******@127.0.0.1:4001/HP4100 5 nobody title 1 
nautilus-debug-log.txt

ERROR: Unable to connect to CIFS host, will retry in 60 seconds...

Obviously, the firewall on Vista is deactivated and the printer is 
accessible.

Has anybody encountered this issue?

Thank you for your coming answers,
Freddy
