To Mount remote windows partition (windows share) under Linux

All files accessible in a Linux (and UNIX) system are arranged in one big tree, the file hierarchy, rooted at /. These files can be spread out over several devices. The mount command serves to attach the file system found on some device to the big file tree.

Use the mount command to mount remote windows partition or windows share under Linux as follows:

Procedure to mount remote windows partition (NAS share)

1) Make sure you have following information:
==> Windows username and password to access share name
==> Sharename (such as //server/share) or IP address
==> root level access on Linux

2) Login to Linux as a root user (or use su command)

3) Create the required mount point:
# mkdir -p /mnt/ntserver
4) Use the mount command as follows:
# mount -t cifs //ntserver/download -o username=vivek,password=myPassword /mnt/ntserver

Use following command if you are using Old version such as RHEL <=4 or Debian <= 3:
# mount -t smbfs -o username=vivek,password=D1W4x9sw //ntserver/download /mnt/ntserver

5) Access Windows 2003/2000/NT share using cd and ls command:
# cd /mnt/ntserver; ls -l
Where,

• -t smbfs : File system type to be mount (outdated, use cifs)
• -t cifs : File system type to be mount
• -o : are options passed to mount command, in this example I had passed two options. First argument is password (vivek) and second argument is password to connect remote windows box
• //ntserver/download : Windows 2000/NT share name
• /mnt/ntserver Linux mount point (to access share after mounting)

SugarCRM is a webbased CRM solution written in PHP. SugarCRM is available in different flavours called "Editions" ("Community" (free), "Professional", and "Enterprise"). For a detailed overview of the different editions, have a look at the SugarCRM website. In this tutorial I will describe the installation of the free Community Edition on Ubuntu 8.10. With the modules My Portal, Calendar, Activities, Contacts, Accounts, Leads, Opportunities, Cases, Bugtracker, Documents and Email, SugarCRM Community Edition offers everything that can be expected from a CRM solution.

1 Preliminary Note

In this tutorial I use the hostname server1.example.com with the IP address 192.168.0.100. These settings might differ for you, so you have to replace them where appropriate.

I will install SugarCRM in Apache's default vhost (document root /var/www) in the directory /var/www/sugarcrm. you might have to adjust this on your system.

Make sure that you are logged in as root (type in

sudo su

to become root), because we must run all the steps from this tutorial as root user.

2 Install The MySQL Database Server

Install unzip to be able to unpack the SugarCRM package later:

apt-get install unzip

Install MySQL:

apt-get install mysql-server mysql-client

You will be asked the following questions:

New password for the MySQL "root" user: <-- yourrootsqlpassword (a password of your choice)
Repeat password for the MySQL "root" user: <-- yourrootsqlpassword

3 Install The Apache Webserver And PHP

apt-get install apache2 apache2-doc apache2-mpm-prefork apache2-utils libexpat1 libapache2-mod-php5 php5-common php5-gd php5-idn php-pear php5-imap php5-mcrypt php5-mhash php5-mysql php5-sqlite php5-xmlrpc php5-xsl php5-curl

Afterwards we need to modify two settings in /etc/php5/apache2/php.ini:

vi /etc/php5/apache2/php.ini

Set the memory_limit to 64M (or more) and the upload_max_filesize to 20M:

[...] ;memory_limit = 16M ; Maximum amount of memory a script may consume (16MB) memory_limit = 64M [...] ; Maximum allowed size for uploaded files. ;upload_max_filesize = 2M upload_max_filesize = 20M [...]

Restart Apache afterwards:

/etc/init.d/apache2 restart

4 Install SugarCRM

You can download SugarCRM Community Edition from http://www.sugarforge.org/frs/?group_id=6 or http://www.sugarcrm.com/crm/download/sugar-suite.html. Pick the latest .zip file (version 5.2.0 at the time of this wrinting) and install it as follows:

mkdir /var/www/sugarcrm
cd /tmp
wget http://www.sugarforge.org/frs/download.php/4902/SugarCE-5.2.0.zip
unzip SugarCE-5.2.0.zip
cd SugarCE-Full-5.2.0/
mv * /var/www/sugarcrm/
chown -R www-data:www-data /var/www/sugarcrm

Start the webbased SugarCRM installer by opening the URL http://server1.example.com/sugarcrm or http://192.168.0.100/sugarcrm in your browser.

The SugarCRM setup wizard comes up:

What is Umask

When user create a file or directory under Linux or UNIX, she create it with a default set of permissions. In most case the system defaults may be open or relaxed for file sharing purpose. For example, if a text file has 666 permissions, it grants read and write permission to everyone. Similarly a directory with 777 permissions, grants read, write, and execute permission to everyone.

Default umask Value

The user file-creation mode mask (umask) is use to determine the file permission for newly created files. It can be used to control the default file permission for new files. It is a four-digit octal number. A umask can be set or expressed using:

• Symbolic values
• Octal values
