this is the log from /var/log/samba/log.smbd
it says it cannot find password db backend "guest".In /etc/samba/smb.conf, there is "passdb backend = guest"

AFAIK passdb backend is used for ldap.
Have you tried to comment out the line? |

if i comment it out, it could startup. But no one could connect samba because of no passdb.
if i change to other passdb backend, anyone could not connect without username & password. |

| Have you set up any smb users? What does your s.b.conf look like?? Give us some clues. |

From which version did you upgrade?
You could try:
| Code: |
passdb backend = ldapsam_compat
|
but i think samba should work finde without the passdb backend variable set. just leave it out |

Noup, doesn't work for me. Neither does just leaving it out! 
Well, actually samba starts when I comment the whole line, but I can't connect the network.

passdb backend is used to set the type of password database in use. Setting it to guest is meaningless and I'm not suprised it doesn't work.
If you want a samba server that can be accessed from windows XP PCs without needing a password then the following configuration is a good example.
| Code: | [global]
workgroup=WORKGROUP
map to guest = bad user
wins support = yes
domain master = yes
local master = yes
os level = 50
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
server string = My Samba Server
[storage]
path = /mnt/storage
guest ok = yes
writeable = yes
create mask = 650
directory mask = 750
force user = dave
force group = users
|
dave is a unix user who has full access to the /mnt/storage directory
Don't use security=share it is very outdated and probably doesn't do what you expect.
Your hosts allow should be 192.168.200.0/24 |

No no no, it just doesn't work for me. It was perfect before upgrading it. No password no nothing it just flew to my shares after booting.
Can you be a littlebit more specific with the configuration, if I want to connect to my shares without password? Because with your example snippet of configuration doesn't work for me. It complains that my network is not accessible plaa plaa. And why you say my host allow should be 192.168.200.0/24 if I don't even have such network? And what "security =" should be if not share? I have tried only user and share.
Also I tried to make my shares accessible with password. I read this tutorial, but no go! And because what you said about using security=share and upgrading my samba, this tutorial seem to be outdated. That is the example I have used to make my previous configuration to work, until now...

Well..
could you post your complete smb.conf?
This way we can modify it for you.
A hint regarding your network class/subnet would be nice too  |

Ok, here it goes! This was my working configuration using samba-3.0.20b. It has some test lines commented, which I tried with no luck.

Any ideas how to make it work again. Also if anyone has any good improvements or if you spot something deprecated options, feel free to say.

Ok, did some mixing with my config.
Add the user "bill" with smbpasswd and it should work.
| Code: |
[global]

hosts deny = 0.0.0.0/0
log file = /var/log/samba/log.%m
dns proxy = no
load printers = no
smb passwd file = /etc/samba/private/smbpasswd
server string = Samba Server %v
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
encrypt passwords = yes
security = user
invalid users = root
max log size = 50
dos charset = 850
unix charset = ISO8859-15
display charset = ISO8859-15
use sendfile = no
large readwrite = no
max xmit = 16644
netbios name = Gentoo-2GHz
workgroup = WINDOWSSUCKS
server string = Blue Gene
interfaces = lo eth0
bind interfaces only = yes
hide dot files = yes
guest ok = no
[1_STUFF]
comment = Stuff
path = /stuff
public = yes
valid users = Bill
writeable = yes
printable = no
browseable = yes
[2_MUSIC]
comment = Music
path = /music
public = yes
valid users = Bill
writeable = yes
printable = no
browseable = yes

A few things to note
If you are using the guest account you do not need to create any samba users
The reason why I use the "force user" setting is that it means I can use different unix users for different shares, without need a password or anything else in windows. e.g. Shares that point to my apache directories use "force user = apache"
There is very little wrong with your orginal config file,
I don't recommend using "security = share" just because this isn't how windows works anymore and it doesn't mean what you think it means. (I disagree with the man page on this)
public = yes is the same as guest ok = yes so you only need one of them.
There are a few redundant lines "share modes", "hide dot files", "encrypt passwords"
The line "passdb backend = smbpasswd guest" should not have the "guest" on the end, alternativley leave it out all together as it isn't needed since "smbpasswd" is the default
Samba is much easier than people think when all you want to do is share a few directories for public access. |

Thanks a lot for the help. Now my samba is up and running perfectly.  So I had a plenty of redundant options in my smb.conf file, which made me confused.
I don't know if it's because of the new version of samba or some of the changet options, but file browsing is a bit faster now. Transfer rates didn't change, but I didn't even expect it.
