It seems /ffp/sbin/smbd appears to be quitting after a few minutes. I used SWAT to monitor the running processes, fired up SWAT, started smbd and nmbd. They both report running in SWAT and in "top". So no issues there. Windows connects to the shares flawlessly, no problems.

After a few minutes, SWAT will report smbd and nmbd as both "not running", and 'top' will not have any entries for /ffp/sbin/smbd -D.

This is really fustrating

Anyone else getting this problem?

EDIT:

Got some info from the level 2 logs (this is from smbd & nmbd start until it dies):

So that means it only lasts about 3 mins

I needed to crank the log file to level 5 to get an error that actually was useful.

That is the last line before smbd quits. HELP!

See google and http://www.inreto.de/dns323/fun-plug/0. … mba-3.4.6/

I'm not that great with the compiling/debugging errors etc. I tried googling, but not sure what people are saying. They do not seem to have a fix for this.

That is the exact version I'm using on ffp. I downloaded it from your ffp website. I only used the samba-3.4.6-1.tgz, not the build files. Do I need to do that? Think it's worth a shot "reinstalling"? How would I go about doing that?

krackpot · 2010-06-28 10:56:06

Strange, I'm not sure what I did that caused it to work now. I think I just resaved the config file from SWAT, and after a few reboots it started working.

krackpot · 2010-06-30 23:50:07

I found out the problem:
/usr/sbin/samba/smbd seems to restart and kick back in after a few minutes following a "smb stop" command. It stops the /ffp/sbin/smbd which is the 3.4.6 version.

A temp fix:
1) Stop the old samba:
smb stop
2) cd into /usr/sbin and rename the samba folder:
mv samba samba-old
3) Start the new 3.4.6 samba:
sh /ffp/start/samba.sh start

This will have to be done every time a reboot is done on the device (Somehow it resets. Maybe because it's on the rootfs?)

I need to find a way to permanently disable the old samba.
Tried Mektub's method from http://dns323.kood.org/forum/viewtopic.php?id=5441 but it doesn't kill it completely.

Code:

On /ffp/etc/fun_plug.local, at the end I inserted:

Code:
echo "* Stopping Samba Services"

/bin/kill `pidof nmbd`
/bin/kill `pidof smbd`
sleep 3
echo 'swat 901/tcp' >>/etc/services

EDIT: The issue persists. /ffp/sbin/samba/smbd still dies after a while. At least it's not getting replaced by the old one.

I had the same problem and for now am trying this in the /ffsp/start/samba.sh

#!/ffp/bin/sh

# PROVIDE: samba
# REQUIRE: LOGIN

. /ffp/etc/ffp.subr

name="samba"
start_cmd="samba_start"
stop_cmd="samba_stop"
status_cmd="samba_status"

smbd_flags="-D --debuglevel=3 --configfile=/ffp/etc/samba/smb.conf"
nmbd_flags="-D"

required_files="/ffp/etc/samba/smb.conf"

samba_start()
{
proc_start /ffp/sbin/smbd
proc_start /ffp/sbin/nmbd
}

samba_stop()
{
proc_stop smbd
proc_stop nmbd
killall -9 smbd
killall -9 nmbd
# prepare a new samba dir with all files
rm -fr /ffp/var/samba
mkdir -p /ffp/var/samba
list="smbd nmbd"
for file in $list; do
ln -fs /ffp/sbin/$file /ffp/var/samba
done
list="smbcacls samba smbget smbpasswd smbcquotas smbtree smbclient smbstatus smbspool smbtar smbcontrol"
for file in $list; do
ln -fs /ffp/bin/$file /ffp/var/samba
done
if [ ! -d /usr/sbin/samba.bak ]; then
mv -f /usr/sbin/samba /usr/sbin/samba.bak
fi
if [ ! -e /usr/sbin/samba ]; then
ln -fs /ffp/var/samba /usr/sbin/samba
fi
}

samba_status()
{
proc_status smbd
proc_status nmbd
}

run_rc_command "$1"

1) I do not see the /usr/sbin/samba/smbd replacing my /ffp/sbin/smbd anymore
2) If it would it should start the ffp version from the symbolically linked samba dir from /ffp/var/samba instead

This is already an old thread but I just faced the same problem described here. I have struggled with this problem already quite a long time but now I finally decided to actually do something about it.

The problem is
/usr/sbin/samba/smbd -D keeps crashing once and a while. (why, I don't know) But when it crashes even "smb restart" doesn't help, only restart.

So I tried a workaround with installing ffp samba-3.4.6-1.

First I put "smb stop" to startup script to stop the original samba server and then "/ffp/start/samba.sh start" to start the ffp samba.
For a while it looked ok, but then the /usr/sbin/samba/smbd kicked in exactly like krackpot explained before.

I tried also the script introduced by "diagpope". It looked to work just fine. But this morning I checked and "/ffp/sbin/samba/smbd" was again replaced by "/usr/sbin/samba/smbd"

How can I destroy/disable "/usr/sbin/samba/smbd" for good? Smbd started in system_init script during boot up. But the file is "read only" so can't edit that either.
