Linux Mint LMDE Server Setup #5: Public file sharing

I use two types of directory/file sharing: Samba and Ftp server

1. Samba

1.1. Mount drive to share:

$ sudo mkdir /mnt/drive
$ sudo mount -t ext4 /dev/<drive> /mnt/drive

1.2. To make the drive automatically mounted on boot, put following text to the end of “/etc/fstab”:

/dev/<drive>	/mnt/drive	ext4	defaults	0	2

1.3. Create folder to share:

$ sudo mkdir /mnt/drive/share

1.4. Change folder permission:

$ sudo chmod 777 /mnt/drive/share

1.5. Edit “/etc/samba/smb.conf”.

1.5.1. In order to make .exe files executable on samba share, put following line in section “global”:

   acl allow execute always = True

1.5.2. Put following text to the end of smb.conf file:

   comment = Freigabe Ordner
   path = /mnt/drive/share
   browseable = yes
   read only = no
   guest ok = yes
   create mask = 0777
   directory mask = 0777

1.5.3. Here is my complete 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 =======================
# Enable file execution
acl allow execute always = True
## Browsing/Identification ###
# Change this to the workgroup/NT-domain name your Samba server will part of
#   workgroup = WORKGROUP
server string = MintServer
# 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 = 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 <<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 ###########
# 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.  
; add group script = /usr/sbin/addgroup --force-badname %g
############ Misc ############
# Using the following line enables you to customise your configuration
# on a per machine basis. The %m gets replaced with the netbios name
# of the machine that is connecting
;   include = /home/samba/etc/smb.conf.%m
# Some defaults for winbind (make sure you're not using the ranges
# for something else.)
;   idmap uid = 10000-20000
;   idmap gid = 10000-20000
;   template shell = /bin/bash
# Setup usershare options to enable non-root users to share folders
# with the net usershare command.
# Maximum number of usershare. 0 (default) means that usershare is disabled.
;   usershare max shares = 100
# Allow users who've been granted usershare privileges to create
# public shares, not just authenticated ones
usershare allow guests = yes
#======================= Share Definitions =======================
comment = Home Directories
browseable = no
# By default, the home directories are exported read-only. Change the
# next parameter to 'no' if you want to be able to write to them.
read only = yes
# File creation mask is set to 0700 for security reasons. If you want to
# create files with group=rw permissions, set next parameter to 0775.

# Directory creation mask is set to 0700 for security reasons. If you want to
# create dirs. with group=rw permissions, set next parameter to 0775.
directory mask = 0700
# By default, \\server\username shares can be connected to by anyone
# with access to the samba server.
# The following parameter makes sure that only "username" can connect
# to \\server\username
# This might need tweaking when using external authentication schemes

browseable = yes
read only = yes
guest ok = no
# Uncomment to allow remote administration of Windows print drivers.
# You may need to replace 'lpadmin' with the name of the group your

$ sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/ssl/private/vsftpd.pem -out /etc/ssl/private/vsftpd.pem

2.4. Create file “/etc/xinetd.d/vsftpd” and put following text into that file:

service ftp
socket_type             = stream
wait                    = no
user                    = root
server                  = /usr/sbin/vsftpd
log_on_success  += HOST DURATION
log_on_failure  += HOST
disable                 = no

2.5. Restart xinetd:

Linux Mint LMDE Server Setup #1: Install LTSP Server

Here is how I installed LTSP Server for 32 bit Clients on Linux Mint Debian Edition 64 bit MATE:

1. Install LTSP server:

$ sudo apt-get install ltsp-server-standalone

2. Set static IP address:

My computer has 3 network adapters (eth0, eth1 and wlan0). I want eth1 to be used by dhcp-server and the rest will be dynamically managed by network-manager.

2.1. Start text editor:

$ sudo nano /etc/network/interfaces

2.2. My “/etc/network/interfaces” looks like this:

# interfaces(5) file used by ifup(8) and ifdown(8)
# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d
auto eth1
iface eth1 inet static

3. Configure DHCP Server:

3.1. Edit file “/etc/ltsp/dhcpd.conf”:

# Default LTSP dhcpd.conf config file.
subnet netmask {
option domain-name "homenet.local";
option domain-name-servers;
option broadcast-address;
option routers;
# get-lease-hostnames true;
option subnet-mask;
option root-path "/opt/ltsp/i386";
if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient" {
filename "/ltsp/i386/pxelinux.0";
} else {
filename "/ltsp/i386/nbi.img";

3.2. Append “/etc/ltsp/dhcpd.conf” at the end of file “/etc/dhcp/dhcpd.conf”:

$ su
# echo "include \"/etc/ltsp/dhcpd.conf\";" >> /etc/dhcp/dhcpd.conf

4. Build client:

$ sudo ltsp-build-client --dist wheezy --arch i386

5. Share LTSP root directory on NFS drive:

$ su
# echo "/opt/ltsp          *(ro,no_root_squash,async,no_subtree_check)" >> /etc/exports

6. Restart Computer.

7. Boot Thin Clients:
