.....for the permanent change put these lines in your fun_plug

The above noted changes have been made however the ffp.log file reports an error and printing continues from HD_a4.

The ffp.log shows the following;

killall: No such file or directory
$Shutting down SMB services:
$Shutting down NMB services:
$Starting SMB services:
$Starting NMB services:
Fatal error - Another print spooler active, possibly lpd process '1669'


The fun_plug file was revised to include the following lines;

USB_LPD_QUEUE=/mnt/USB/ffp/var/spool

# Establish availability of USB Drive and move print queue if available
if [ -d $USB_LPD_QUEUE ]; then
    echo "* Moving Print Queue to USB Drive"
    killall lpd
    cp $USB_LPD_QUEUE/printcap /usr/local/LPRng/etc/printcap
    smb restart
    lpd&
fi

The printcap file was modofied to read as follows;

lp|USB Printer:\
        :sh:\
        :ml=0:\
        :mx=0:\
        :sd=/mnt/USB/ffp/var/spool/lpd:\ 
        :lp=/dev/usblp0:\

My skills on the Linux side are very limited and I don't understand why these errors are occuring. Any help in this regard would be appreciated.

seems to me like you've added the lines too soon in fun_plug. (before /ffp symlink is created and/or suid busybox).

try to move it bit more further in the file... i have it just above the last RC_D run... if that fails, use full path to killall (/ffp/bin/killall

My lines of code were placed at the end of the fun_plug file; same place as your's were placed. I've a sneaking suspicion the USB drive is still being set-up when the killall command was being issued. Adding the full path to the command has corrected the problem.

also, there is one more thing i forgot to mention in the first post. in /etc/samba/smb.conf there is [ printers ] section. and the "path = " variable in there should be edited to reflect the changes too. will edit the instructions now and make sure you do that part too

There's always a slight chance the USB drive might not mount so to avoid problems two copies of the smb.conf were placed in the /ffp/etc folder. One file is named smb.conf.default, the other smb.conf.usb. The smb.conf.usb file is copied to the /etc/samba/ directory as smb.conf if the USB drive mounts successfully. As a precaution, the smb.conf.default was left unedited and is copied to the /etc/samba/ directory as smb.conf if the USB drive fails to mount. The following lines were added to the fun_plug file and start the print queue as deemed appropriate;

USB_LPD_QUEUE=/mnt/USB/ffp/var/spool

<other ffp code removed for clarity purposes>

# Establish availability of USB Drive and move print queue if available
/mnt/USB/ffp/bin/killall lpd
if [ -d $USB_LPD_QUEUE ]; then
    echo "* Print Queue established on USB Drive (/mnt/USB/ffp/var/spool/lpd)"
    cp $USB_LPD_QUEUE/printcap /usr/local/LPRng/etc/printcap
    cp /mnt/USB/ffp/etc/smb.conf.usb /etc/samba/smb.conf
else
    echo "* Print Queue established on Hard Drive (/mnt/HD_a4/.lpd)"
    cp $USB_LPD_QUEUE/printcap /usr/local/LPRng/etc/printcap
    cp /mnt/HD_a2/ffp/etc/smb.conf.default /etc/samba/smb.conf
fi
smb restart
lpd&

I see one downfall of using this approach; if I later changes Samba Shares, it will be necessary to copy and re-edit the /etc/samba/smb.conf file. Any ideas on how this can be avoided?

Hi there!

Do I understand this correctly, that the Samba settings are overwritten after each boot with the backed up version? So that all possible changes are made undone? What settings are actually stored in this smb.conf?

Regards
Ben

Edit /etc/samba/smb.default
And update mtd1 and mtd2":
mount -t minix /dev/mtdblock0 /sys/mtd1
cp /etc/samba/smb.default /sys/mtd1/smb.default
sync
umount /sys/mtd1
mount -t minix /dev/mtdblock1 /sys/mtd2
cp /etc/samba/smb.default /sys/mtd2/smb.default
sync
umount /sys/mtd2
