Hi, check out

for an example of samba stuff

this seems interesting....

i didnt thinkg of other stuff other than logs

Runing samba on FLASH (USB stick) memory

To minimize FLASH wear, redirect all logs and temporary databases to /tmp/samba directories. One way to do is to create startup script like

#!/bin/sh
if [ -n "`pidof smbd`" ] ; then
    echo "Stopping smbd:"
    killall smbd
fi

if [ -n "`pidof nmbd`" ] ; then
    echo "Stopping nmbd:"
    killall nmbd
fi

#sleep 2

echo "Starting smbd:"
if [ ! -d /tmp/samba ]; then
        mkdir /tmp/samba
        mkdir /tmp/samba/log
        rm -rf /opt/var/log/samba
        ln -s /tmp/samba/log /opt/var/log/samba
        rm -rf /opt/var/samba
        ln -s  /tmp/samba /opt/var/samba
fi
/opt/sbin/smbd -D;
echo "Starting nmbd:"
/opt/sbin/nmbd -D;

@dm,

Cool! I'll add this into the autorun.sh script. Since you've installed opt on your USB drive, you could use iotop to verify if samba only writes to /tmp after you've done this? I've run out of space on /usr/local/etc and have not tried installation on USB yet.

Regarding user/password, I will see if we can add that restricted access share.

@jea

In the optware-install.sh script, change OPTDIR="/usr/local/etc" to OPTDIR="tmp/usbmounts/sda1" (or whatever the USB drive letter is sdb1, sdc1,...) and it should be enough. samba-install.sh installs to /opt and after you've installed optware,you got /opt mounted to your USB drive already so no change needed.

[jea101]

I installed Optware and samba on the flash drive.

Now I have script problems.

Before I did a reboot I ran the S80samba script. When the script finished a PS showed smbd was running but nmbd was not. When I rebooted sda1 was mounted ro so I added a umount and mount to the new autorun script. After the next reboot sda1 was still mounted ro. I manually ran the autorun script and it found sda1, mounted it rw and mounted /opt. I manually ran S80samba script and once again smbd was running and nmbd was not. I did notice that syslogd was running. I added the lines to move the log to tmp and rebooted – no change

The good news is that when I restore the original autorun script and removed the flash drive everything works as before (I haven't remove optware from usr/local/etc).

cat autorun.sh
#!/bin/sh

    umount -l /tmp/usbmounts/$usb_drive;

I fixed the nmbd problem. When I installed to the flash drive I got the unmodified smb.conf. I replaced it with my modified smb.conf and both smbd and nmbd start.

So my only problem appears to be with autorun.sh. If I manually run it and then run the S80samba script I now have samba running from the flash drive.

[dm]

@jea,

Im not sure by TO BE SAFE>>>>>>

Always add like

pause 20 or something to the beginning of the autorun.sh

if not and something breaks the system you'll maybe never get in.

this gives a 20second wait before the script runs.

i thnk thats also good to give the time to find everything.

IF things get wierd. POWER OFF (umount something  if it never pwoers off and kills the telnet)

then PULL the powerr. try again.

@bodhi,

I actually am using it on the /usr/local/etc now

i cant make up my mind

i tried busybox iotop and i did nt see specific directories. what commands should I use?

FOR the password setup, WELL as far as I can tell password user on the samba will need a user on the passwd file, so other than changing the etc password file just

mount bind it from usr/local/etc (make a copy...)

then ADD a user to it, maybe guest or whatever the default is.

I think when I tried with the setting of NOT public, it went to use venus/guest as a user but guest does not exist. So make  anew passwd file with guest added with a password of wahtever? then sambapass -add the user?

btw, why do we want syslogd running?

ps...

/usr/local/etc # bin/busybox-mipsel mountpoint /opt
/opt is a mountpoint
/usr/local/etc # bin/busybox-mipsel mountpoint /opt123
mountpoint: /opt123: No such file or directory
/usr/local/etc # bin/busybox-mipsel mountpoint /usr
/usr is not a mountpoint
/usr/local/etc #

@ *

Do we really need to do this every time?

        rm -rf /opt/var/log/samba
        ln -s /tmp/samba/log /opt/var/log/samba
        rm -rf /opt/var/samba
        ln -s  /tmp/samba /opt/var/samba
, the /tmp DIR will be absant every time we boot right? since its /tmp ..so, that should be more if the ln part doesnt exist in our case?

@Bodhi, how about this to resolve double mount..

### OPTWARE STARTUP
if  bin/busybox-mipsel mountpoint /opt ; then
   echo /opt already mounted
else
   echo Mounting /opt
   mount -o bind /usr/local/etc/oleg-optware /opt
fi
###

so no worry to mount if its mounted already? PS this needs the new busybox somewhere...lala

@dm,

I'm glad it works   IMHO, using the USB flash drive is too much of a hassle. Because the drives move around, currently my USB thumb drive is stuck at sdb1. I think this was because the Ext3 USB thumb drive mounting. And I also experienced a power OFF problem similar to you've reported, only after using the Ext3 drive for a while (I have not even mounted /opt on it).  Beside, if anyone wants to run transmission, it's already in optware. ...Wish we have more flash memory then it's a moot point!

I'm not sure, I think we do need the samba log setup like that because the /tmp will be there but it will be empty. I have not tried to pull the power cord to see what will happen.

syslogd does not take up much space, and it's handy when you want to see cron jobs running. I'm setting up one to run every 5 minutes to test one of my theories to keep the FAT+ running 24/7. But other than that, it doesn't show much (hotplug activities did not show up when I run logread).

PS. to run iotop  #iotop -o -b -qqq

i think you may have missed my edit of

### OPTWARE STARTUP
if  bin/busybox-mipsel mountpoint /opt ; then
   echo /opt already mounted
else
   echo Mounting /opt
   mount -o bind /usr/local/etc/oleg-optware /opt
fi

Nice! so this will avoid unmounting /opt and remount, and we dont need to do the search?

[dm]

search.. not sure

Im guessing most people will just use the /usr/local/etc

if someone knows how to format their external SDA as ext3 then they know enough on how to fix the scripts

other than that, i saw, have a text file in the oleg-optware dir that says _USEME_ 

if that is there mount that opt and not another? no idea.

this is good enough i guess

im still playing with samba passwords

so for i got...

fist in the script...
cp /etc/passwd /opt/etc/passwd

mount -o bind /opt/etc/passwd /etc/passwd

then we can edit passwords for the system.

technically then you can passwd protect your system.

BTW, *** put a pause in your autorun.sh or people may get toasted.... you need enough time to telnet in and rm /usr/local/etc/autorun.sh

[bodhi78]

You're right about ext3 and people who know how to use it will change the autorun script to deal with it. I'll just leave the autorun.sh like it currently is (no mounting /opt) . So no chance of causing problem
