Re: [Samba] Slow file transfer on ADDC mode




Hi Rowland

Thank you for your reply, i removed them but nothing changed :(, i also tried to remove others thing like the full_audit module to keep the settings simplest as possible but had no effect, i'll try to build samba with profiling support and debug with some tools like gdb which i don't have much experience but i'll try it.


The current Samba versions support the production/stable version of Windows 10 SMB3 ? I'm asking this because on the smb.conf man page it says "Technical Preview", i decided to try to set max protocol to windows 8.1 SMB3_02 because i had some issues with Windows 10 client machines ,some of these machines was hanging during logon , Excel crashing while editing files and doing this didn't happen anymore. When you look at client  smb sessions with smbstatus command,the protocol version negotiated of Windows 10 machines appears as "unknown", is this normal ?

Best Regards
Dante

Try doing this:

Remove these lines from [global]

os level = 255 
admin users = leonardo.soares 
server services = s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, drepl, winbindd, ntp_signd, kcc, dnsupdate, dns 
max protocol = SMB3_02 
debug class = yes 
debug prefix timestamp = yes 
use sendfile = yes 
smb2 leases = no 
dbwrap_tdb_mutexes:* = yes 
max stat cache size = 65536 

They are either the defaults or shouldn't be used on an AD DC

Change [profiles to this:

[profiles] 
    path = /samba/profiles
    read only = no

Change [Homedirs] to this:

[Homedirs] 
    path = /samba/homedirs 
    read only = no

Ghange [RH} to this:

[RH]
    path = /samba/files/rh 
    read only = no
    vfs objects = full_audit
    full_audit:prefix = "%u|%I|%P" 
    full_audit:success = rmdir unlink rename 
    full_audit:failure = rmdir unlink rename 
    full_audit:facility = LOCAL0 
    full_audit:priority = NOTICE 

acl_xattr is built into Samba when running as an AD DC, so you cannot
use the old way of doing things, see here for a start:
