Harbour/[x]Harbour LAN STRES UTIL

[Roberto Borges]

Greetings to my noble and dear and dear colleagues.

Recently, a Great Friend has asked me to set up a file server for one of their clients, which runs their APP on Good and Old War Clipper. But it would have to be extremely simple, robust, effective, stable at low cost and very high throughput, without the use of AD / DC, of ​​users / groups and complex passwords, it would be a resource share, appearing in the Network as a remote drive (F: \), similar to Novell NetWare, is clear and obvious keeping its due proportions. Well, I requested the purchase of a Core i8, with 16GB of RAM and 1TB of HD at 7200 RPM's. And GigaBit Ethernet network card. I installed the Ubuntu 18.04 Server LTS AMD64, as well as the SAMBA provided by the distribution packages. I used the XFS file system because of its stability, scalability, reliability, and maturity. This is in LVM configuration. When migrating to this new environment, my friend was impressed with the gain from the old server, doing and redoing the tests, even by giving up and convinced, that it was worth the migration, and in a Old server crashed moments later, UFA, lucky LUCK luck, and there is still a factor, the aina network switch is a 10/100 Fast Ethernet, I have already requested a 10/100/1000 GigaBit Ethernet switch.

To make it easier for colleagues, I created a program for network stress, using some routines that I took from NET and adding some others of my own, please take it easy, I'm an IT enthusiast, not a programmer. Rsrsrsrssr.

I'll send the sources as well as .HBP.

It's only 3 files.

smbstres.hbp

main.prg

librgblc.prg

hbmk2 smbstres.hbp, and that's it ... just check it out ...

The idea is to create a certain number of files and records, and it will create all that traffic on the network.

Limited to 62,779 (.DBF'S) in * Unix Like, and 124 in Ms-Dos Like, for Windows, I do not have any equipment available for testing.

Let's adjust first ...

As well as some tweaks in the Ubuntu configuration. That said, let's go to the facts.

Hi Roberto

Thank you for this code.

I think that the most important file in your setup is the one you didn't send... samba configuration.

It is important, in some cases of vital importance, that OPLOCKS are disabled in samba... disabling oplocks, you will incur in speed penalties, varying depending on your code...

Oops .... TKS Fperillo ...

smb.conf

=======

#

# 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. 

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

[global]

## Browsing/Identification ###

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

   workgroup              = client

   netbios name           = SERVER

   realm                  = CLIENT

   netbios name           = SERVER

   server string          = SERVER

   security               = user

   usershare allow guests = Yes

   guest ok               = yes

# 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

#### 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 = 127.0.0.0/8 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

#### 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 #######

# Server role. Defines in which mode Samba will operate. Possible

# values are "standalone server", "member server", "classic primary

# domain controller", "classic backup domain controller", "active

# directory domain controller". 

#

# Most people will want "standalone sever" or "member server".

# Running as "active directory domain controller" will require first

# running "samba-tool domain provision" to wipe databases and create a

# new domain.

   server role = standalone server

# 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 <<ka...@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 ###########

#

# The following settings only takes effect if 'server role = primary

# classic domain controller', 'server role = backup domain controller'

# or '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

# The following setting only takes effect if 'domain logons' is set

# 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

# This allows Unix users to be created on the domain controller via the SAMR

# 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

# This allows machine accounts to be created on the domain controller via the 

# 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.

[Diego Fazio]

In the smb.conf in [Global] add 

max protocol = SMB2

And disable the SMBv1 in windows clients

You did not think about using SSD? it's a really significant difference. If you host incremental databases it's perfect.

Diego.

[Francesco Perillo]

Is smb2 usable? Shouldn't he disable oplocks?

[Diego Fazio]

Both yes.

I forgot....I think the change must be...

[global]

"min protocol = SMB2"

and not "max protocol" and then restart the server.

Diego.
