[FreeNX-kNX] Cups 1.2.7 IPP_PORT solution

[Marcel kraan]

I have talked to Tim Waugh and he told me :

Don't set IPP_PORT in the environment; instead put 'ServerName
localhost:10000' in your client.conf (~/.cups/client.conf
or /etc/cups/client.conf).

So i have changed the following in the nxnode script.
It works with mozilla and other applications.
openoffice sees the printer but is hiding the printbutton. (unclickable)


nxnode (line +/- 370)
node_cupsd_setup()
{
..
..
..
..        mkdir -p $USER_FAKE_HOME/.nx/C-$sess_id/cups/spool/tmp $USER_FAKE_HOME/.nx/C-$sess_id/cups/spool/certs $USER_FAKE_HOME/.nx/C-$sess_id/cups/ppd
..        ln -sf spool/certs $USER_FAKE_HOME/.nx/C-$sess_id/cups/certs


# added by marcel at kraan.net this is a replacement for the IPP_PORT var.
# we don't remove the .cups folder at shutdown maybe it was already there?
mkdir -p "$USER_FAKE_HOME/.cups"
cat <<EOF > $USER_FAKE_HOME/.cups/client.conf
ServerName localhost:$NODE_CUPSD_PORT
EOF

..
..
