Re: [Samba] pam_smbpass.so passdb.tdb support
Dear John T and samba list, Can you please help me to understand following things. I have browsed the net , points are not clear to me. 1) What exactly doesn't work with the existing smbpasswd based mechanism? -- from http://www.samba.org/samba/docs/man/Samba-HOWTO-Collection/passdb.html#i d2593073 This form of password backend does not store any of the MS Windows NT/200x SAM (Security Account Manager) information required to provide the extended controls that are needed for more comprehensive interoperation with MS Windows NT4/200x servers. what exactly is the above point? is it the only one limitation?. is there any other limitations?.please let me know if any other. 2) Can we easily convert an existing smbpasswd file to the new format and allow system authentication to work uninterrupted?

[Samba] Fat32 - 1Gb file copy is failing
Hi All,
Setup :- NAS device is running with 2.6.13 kernel and samba 3.0.32.I
have connected a 4GB USB flash drive having FAT32.USB drive is
available from the windows machine as connected shared drive.
From my windows machine when I am trying to copy the file (1Gb) to
shared USB drive(FAT32).it is giving error as shared USB drive is not
reachable.
File copy is working fine with small files.
And I could copy the files more than 1Gb when the drive is with NTFS and
other file systems
I went though the code.
In the following samba code piece:
samba-3.0.32_old/source/modules/vfs_default.c:
714 static int vfswrap_ftruncate(vfs_handle_struct *handle,
files_struct
*fsp, int fd, SMB_OFF_T len)
715 {
...
734
735 result = sys_ftruncate(fd, len);
736 if (result == 0)
737 goto done;
738
If comment out line 735/736 (not to extend space for the file to copy on
fat),
no error will occur during copying. (But we cannot do so otherwise all
truncate
requests from client would be skipped)
Please advice me what is the exact poblem,or it is known bug?. Any
reply will be appreciated .
Thanks in advance
Suresh

[Samba] Windows xp is waking up NAS for every 30 minutes with NBSS session service packets
Dear All, Sorry to bothering you. I am beginner to samba. Please help me regarding the below problem. while I am testing my NAS disk standby(sleep) mode, I noticed windows xp (Professional version 2002 SP2) PC on the network is sending NBSS session service packets for every 30 minutes to NAS and this causing the parent smbd in NAS to spawn worker smbd and this smbd is accessing some of the files on disk( group_mapping.tdb,account_policy.tdb,shar_info.tdb) and causing spinup. On this XP computer I have closed all network connections and already disabled the automatic searching for new network shares. Nevertheless, every 30 minutes the system idle process (PID 0) initiates a connection the to netbios-ssn port on the NAS. I have tried with another windows xp PC .it is also behaving the same manner. Windows vista ultimate is not giving any problem like this. I have two questions here?. 1) Why and for what windows xp is sending these packets?. 2) Is there a way to handle these packets at NAS samba side?. like patches are available, Thanks in advance.
