Unhappy Samba share slow lan connection; help!


I have 2 1TB samba servers on to ubuntu servers, all hooked up to a 1gb/s switch. But when i try to upload a file or copy files to them, they only copy at 2,5 megabyte/s. I have tryed to fix it ub tcant understand what's wrong. P help. https://lqo-thequestionsnetw.netdna-...s_lq/icon9.gif

Check the network speed's between the samba server and client with a tool such as iperf:

Using scp or another protocol to a transfer, to make sure it's not samba it could be network related.

http://blog.softlayer.com/2011/using...ughput-issues/


Add this to the [global] section in your /etc/samba/smb.conf

Code:
socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=65536 SO_SNDBUF=65536
service samba restart

Now test the speeds, see if it made a difference.

Frustrated

I changed the smb.conf and it is the same, 6-9 mbps copying file from/to server, but only 2,5 mpbs from server to server. NOTE: it is all wired in gigabit ethernet switch... DONNO WHAT TO DO!

Give us the output of both servers:

Code:
cat /etc/samba/smb.conf

What version of Ubuntu are you using on the servers?

Code:
lsb_release -a

What version of Samba?

Code:
smbstatus

# Sample configuration file for the Samba suite for Debian GNU/Linux.
#
#
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options most of which
# are not shown in this example
#
# Some options that are often worth tuning have been included as
# commented-out examples in this file.
# - When such options are commented with ";", the proposed setting
# differs from the default Samba behaviour
# - When commented with "#", the proposed setting is the default
# behaviour of Samba but the option is considered important
# enough to be mentioned here
#
# NOTE: Whenever you modify this file you should run the command
# "testparm" to check that you have not made any basic syntactic
# errors.
# A well-established practice is to name the original file
# "smb.conf.master" and create the "real" config file with
# testparm -s smb.conf.master >smb.conf
# This minimizes the size of the really used smb.conf file
# which, according to the Samba Team, impacts performance
# However, use this with caution if your smb.conf file contains nested
# "include" statements. See Debian bug #483187 for a case
# where using a master file is not a good idea.
#

#======================= Global Settings =======================

[global]

## Browsing/Identification ###

# Change this to the workgroup/NT-domain name your Samba server will part of
workgroup = WORKGROUP

# server string is the equivalent of the NT Description field
server string = %h server (Samba, Ubuntu)

# Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable its WINS Server
# wins support = no

# WINS Server - Tells the NMBD components of Samba to be a WINS Client
# Note: Samba can be either a WINS Server, or a WINS Client, but NOT both
; wins server = w.x.y.z

# This will prevent nmbd to search for NetBIOS names through DNS.
dns proxy = no

# What naming service and in what order should we use to resolve host names
# to IP addresses
; name resolve order = lmhosts host wins bcast

#### Networking ####

# The specific set of interfaces / networks to bind to
# This can be either the interface name or an IP address/netmask;
# interface names are normally preferred
; interfaces = 10.0.0.101/8 eth0

# Only bind to the named interfaces and/or networks; you must use the
# 'interfaces' option above to use this.
# It is recommended that you enable this feature if your Samba machine is
# not protected by a firewall or is a firewall itself. However, this
# option cannot handle dynamic or non-broadcast interfaces correctly.
# bind interfaces only = yes
socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=65536 SO_SNDBUF=65536


#### Debugging/Accounting ####

# This tells Samba to use a separate log file for each machine
# that connects
log file = /var/log/samba/log.%m

# Cap the size of the individual log files (in KiB).
max log size = 1000

# If you want Samba to only log through syslog then set the following
# parameter to 'yes'.
# syslog only = no

# We want Samba to log a minimum amount of information to syslog. Everything
# should go to /var/log/samba/log.{smbd,nmbd} instead. If you want to log
# through syslog you should set the following parameter to something higher.
syslog = 0

# Do something sensible when Samba crashes: mail the admin a backtrace
panic action = /usr/share/samba/panic-action %d


####### Authentication #######

# "security = user" is always a good idea. This will require a Unix account
# in this server for every user accessing the server. See
# /usr/share/doc/samba-doc/htmldocs/Samba3-HOWTO/ServerType.html
# in the samba-doc package for details.
# security = user

# You may wish to use password encryption. See the section on
# 'encrypt passwords' in the smb.conf(5) manpage before enabling.
encrypt passwords = true

# If you are using encrypted passwords, Samba will need to know what
# password database type you are using.
passdb backend = tdbsam

obey pam restrictions = yes

# This boolean parameter controls whether Samba attempts to sync the Unix
# password with the SMB password when the encrypted SMB password in the
# passdb is changed.
unix password sync = yes

# For Unix password sync to work on a Debian GNU/Linux system, the following
# parameters must be set (thanks to Ian Kahan <<kahan@informatik.tu-muenchen.de> for
# sending the correct chat script for the passwd program in Debian Sarge).
passwd program = /usr/bin/passwd %u
passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .

# This boolean controls whether PAM will be used for password changes
# when requested by an SMB client instead of the program listed in
# 'passwd program'. The default is 'no'.
pam password change = yes

# This option controls how unsuccessful authentication attempts are mapped
# to anonymous connections
map to guest = bad user

########## Domains ###########

# Is this machine able to authenticate users. Both PDC and BDC
# must have this setting enabled. If you are the BDC you must
# change the 'domain master' setting to no
#
; domain logons = yes
#
# The following setting only takes effect if 'domain logons' is set
# It specifies the location of the user's profile directory
# from the client point of view)
# The following required a [profiles] share to be setup on the
# samba server (see below)
; logon path = \\%N\profiles\%U
# Another common choice is storing the profile in the user's home directory
# (this is Samba's default)
# logon path = \\%N\%U\profile

# The following setting only takes effect if 'domain logons' is set
# It specifies the location of a user's home directory (from the client
# point of view)
; logon drive = H:
# logon home = \\%N\%U

# It specifies the script to run during logon. The script must be stored
# in the [netlogon] share
# NOTE: Must be store in 'DOS' file format convention
; logon script = logon.cmd

# RPC pipe. The example command creates a user account with a disabled Unix
# password; please adapt to your needs
; add user script = /usr/sbin/adduser --quiet --disabled-password --gecos "" %u

# SAMR RPC pipe.
# The following assumes a "machines" group exists on the system
; add machine script = /usr/sbin/useradd -g machines -c "%u machine account" -d /var/lib/samba -s /bin/false %u

# This allows Unix groups to be created on the domain controller via the SAMR
# RPC pipe.
; add group script = /usr/sbin/addgroup --force-badname %g

########## Printing ##########

# If you want to automatically load your printer list rather
# than setting them up individually then you'll need this
# load printers = yes

# lpr(ng) printing. You may wish to override the location of the
# printcap file
; printing = bsd
; printcap name = /etc/printcap

# CUPS printing. See also the cupsaddsmb(8) manpage in the
# cupsys-client package.

Try changing the this order:

Code:
; name resolve order = lmhosts host wins bcast
To:
Code:
name resolve order =  dns host wins lmhosts bcast
Code:
service smb restart

Is it different speeds from different versions of Windows ?

E.g: try copying files from a samba client using Windows XP and one from Windows 7, is there any difference in speed?

If you are having issues with Windows 7 Clients read and try this:

The speeds are the same, only I'm getting 4mbps between the two servers, so not much faster.. Used ubuntu too, same speeds

If your transferring between the Ubuntu Servers why not use NFS or SSHFS as a share?

Samba is the standard Windows interoperability suite of programs for Linux and Unix, if your going Linux to Linux use something more native.

you beat me to it. if you are going Linux to Linux, then you are using the wrong protocol for file sharing. you should be using the native NFSv4 not SAMBA. SAMBA is for sharing between MS Windows and Linux.

We understand that you use Windows and that's why you have Samba share to share Linux shares between the Windows Clients.

However we are saying setup an NFS share between the Ubuntu Servers then check the transfer speeds, you can have NFS and Samba shares on the same machine.

Tests

First lets see if you are able to achieve faster speeds from your samba server. Take your station, or laptop, and connect it directly to the samba server via cross connect cable, and setup static IP address on it so communication can occur, and do a very large file transfer test, and also huge number of small files transferred as a group, and let us know if you get faster speeds on both transfers.

If you get fast speeds from above tests, then put the switch in between the two, and have everything else disconnected (yes, I know what I am asking can be scary in a large network environment; you could put in a backup switch temporarily) and try the tests again.

Report back.
