Yes, smbd version shows '3.6.0pre1-GIT-f87ecd7-test' so I think/hope I am testing v3-6-test tree :-) I have opened bugid 7653 and attached log files of a test case ( https://bugzilla.samba.org/show_bug.cgi?id=7653 ) Thanks a lot for your help.

You do realize security = user can do everything that security = share can do, don't you ? No I did not :-) Back to Google, I have just discovered the magical map to guest = Bad Password setting which allows (me) to make guest connections to shares while in security = user mode. I'm pretty sure SMB2 guest connections work with security = user (as that's how I test them :-). Indeed it works. :-) Thanks a lot !!! I can go back to SMB2 performance testing which was the original purpose of enabling smb2.

I'd recommend not enabling SMB2 on 3.5.x, it's not ready for production use. SMB2 will be production ready in 3.6.0. OK. I have also tried 3.6-pre1 and git version. Same result : Win7 clients can not connect to a guest ok share. Should I file a bug on this ? The reason I am trying SMB2 is that I also have a Windows 2008 Server (running on the same type of hardware as the Samba servers) and its performance are a lot better when talking to Windows 7 clients. Typically : - reading from samba servers reaches 70 MB/s - reading (same files on same client) from windows server gives over 100 MB/s Apart from the use of SMB2 protocol, I can't see why Windows Server 2008 would be so faster than Samba.

[Samba] Windows 7 with smb2 can not connect as guest ?
Hello, on our servers we have shares with no authentication required (no DC, security = share, guest ok = yes). Worked fine for years, but now with Samba 3.5.4, when I enable smb2, Windows 7 clients can not connect anymore to these shares. Looking at the logs, I can see : [...] [2010/08/25 10:13:08.058358, 3] auth/auth_sam.c:399(check_sam_security) check_sam_security: Couldn't find user 'comp2_2' in passdb. [2010/08/25 10:13:08.058371, 5] auth/auth.c:268(check_ntlm_password) check_ntlm_password: sam authentication for user [comp2_2] FAILED with error NT_STATUS_NO_SUCH_USER [2010/08/25 10:13:08.058386, 2] auth/auth.c:314(check_ntlm_password) check_ntlm_password: Authentication for user [comp2_2] - [comp2_2] FAILED with error NT_STATUS_NO_SUCH_USER [...] So it seems Samba tries to authenticate the user whereas it's a 'guest ok' share. In the meantime, XP clients have no problem connecting. Here is the smb.conf : --- [global] workgroup = WIZZ server string = Prod1bis File Server %v log file = /var/log/samba/log.%m max log size = 50 max protocol = smb2 log level = 10 security = share encrypt passwords = yes dns proxy = no guest account = root load printers = no printing = bsd printcap name = /dev/null disable spoolss = yes getwd cache = yes [partage] comment = Partage browseable = yes writable = yes path = /space/partage guest ok = yes --- Any idea ?

Do you see different performance between the XP and Win7 clients ? I know you say the same performance above, but have you looked closely at this ? Honestly I did not look too closely. The Win7 clients might look a little bit faster, like a few extra MB/s during transfer compared to XP clients, but this might be due to hardware, more recent on Win7 hosts. I'll try to produce detailed numbers later... Thanks, Francois Jeremy -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba
[Samba] Samba transfer rate slower than ftp
Hello, I have a file server under Debian Lenny, with a 41TB file system (XFS, 24 x 2TB hard drives on RAID 6 on an Areca card) Reading files with ftp works like a charm and we easily reach the 125 MB/s limit of the GB ethernet card. But when reading files (on the same clients) from a samba share, we get around 60 MB/s. Clients are Windows XP 64 and Seven 64 and show the same performances. Sadly enough, this server has a 'twin brother' (same hardware) that runs Windows Server 2008, and reading from a share on it gives a nice 100MB/s. So why is the samba share so 'slow' compared to ftp or the windows server ? Here is the smb.conf (samba version is 3.2.5) - [global] workgroup = WIZZ server string = Prod1 File Server %v log file = /var/log/samba/log.%m max log size = 50 security = share encrypt passwords = yes socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=8192 SO_SNDBUF=8192 dns proxy = no guest account = root load printers = no printing = bsd printcap name = /dev/null disable spoolss = yes getwd cache = yes dead time = 30 [partage] comment = Partage browseable = yes writable = yes path = /space/partage guest ok = yes I have also tried without any socket options, or with the following options socket options = TCP_NODELAY IPTOS_LOWDELAY IPTOS_THROUGHPUT SO_RCVBUF=262142 SO_SNDBUF=262142 SO_SNDLOWAT SO_RCVLOWAT min receivefile size=16384 use sendfile = true aio read size = 1 aio write size = 1 but this did not give any improvement.
