What is CRM?

Customer relationship management (CRM) is a term that refers to practices, strategies and technologies that companies use to manage and analyze customer interactions and data throughout the customer lifecycle, with the goal of improving business relationships with customers, assisting in customer retention and driving sales growth. CRM systems are designed to compile information on customers across different channels -- or points of contact between the customer and the company -- which could include the company's website, telephone, live chat, direct mail, marketing materials and social media. CRM systems can also give customer-facing staff detailed information on customers' personal information, purchase history, buying preferences and concerns.

How to Install FreeRadius for SSH Authentication on Centos 6

Install FreeRadius for SSH Authentication (Two-Factor Authentication)

What is FreeRadius?

Radius is a great standard. It is powerful enough to accomplish a great deal and simple enough to be easy to handle. Freeradius is an excellent, open source radius server that ships with many Linux variants. It is well documented and well supported. The WiKID Strong Authentication server is a commercial/open source two-factor authentication system that uses public key encryption to transmit PINs and one-time passcodes securely to software tokens running on Blackberries, cell phones, Palms, PocketPCs or, using the J2SE client, Linux, Macs and Windows PCs. You can think of WiKID like certificates, but without the hassles of white lists/black lists and more secure - because the PIN is validated on the server preventing offline brute-force attacks.

Requirement: 1. 2 CentOS 6 Server (1 for FreeRadius & 1 for SSH Authentication)

Step 1: Stop the IPTables and Selinux, and Update the Date Time on the Servers :

# service iptables stop
# chkconfig iptables off

# vi /etc/sysconfig/selinux

SELINUX=disabled ###(Change enabled to disabled)

--- save & quit (:wq) ---

# service ntpd restart
# ntpdate pool.ntp.org
# chkconfig ntpd on
# init 6

** Configure FreeRadius Server:

Step 2: Install and Configure Radius Server and its Dependencies :

# yum install freeradius freeradius-mysql freeradius-utils mysql-server -y
# service mysqld start

* Set MySQL Root Password by the Following Command:

# mysql_secure_installation

mysql -uroot -p
Enter password:

mysql> CREATE DATABASE radius;
mysql> GRANT ALL PRIVILEGES ON radius.* TO radius@localhost IDENTIFIED BY "radpass";
mysql> flush privileges;
mysql> use radius;
mysql> SOURCE /etc/raddb/sql/mysql/schema.sql;
mysql> \q

* Edit and Check the DB Connection once-

# vi /etc/raddb/sql.conf

### (In Between Line Number 36-42)

# Connection info:
       server = "localhost"
       #port = 3306 login = "radius"
       password = "mypassword"

       # Database table configuration for everything except Oracle
       radius_db = "radius"
 
---- save & quit (:wq) ----

# vi /etc/raddb/radiusd.conf

## Uncomment the Following Line (Line Number 735)

$INCLUDE sql.conf

---- save & quit (:wq) ----

# vi /etc/raddb/sites-available/default

### uncomment the line containing ‘sql’ in theauthorize{} section and ‘sql’ in the accounting {} section, also uncomment ‘sql’ under session{}

### Line Number 177 & Line Number 406


---- save & quit (:wq) ----

# vi /etc/raddb/sites-available/inner-tunnel

### uncomment the line containing ‘sql’ under “authorize {}” and under session {}

## Line Number 132

---- save & quit (:wq) ----

* For change the secret key of the radius server-

# vi /etc/raddb/clients.conf

### Change: secret = testing123 to secret = <your-secret-password>

---- save & quit (:wq) ----

# service radiusd restart

Step 3: Adding Clinets and Users to the Radius Server :

# vi /etc/raddb/clients.conf

client SERVER_IP {
              secret          = YOUR SECRET
              shortname       = yourVPN
 nastype        = other
   }
 
---- save & quit (:wq) ----

# service radiusd restart

# mysql -uroot –p
Enter password:

mysql> use radius;
mysql> INSERT INTO `radcheck` (`username`, `attribute`, `value`) VALUE ('testuser', 'password', 'User_Password');
mysql> \q

* Test the Radius Authentication--

# radtest testuser password localhost 1812 <Radius-Server-Secret-Key>

rad_recv: Access-Reject packet from host 127.0.0.1 port 1812, id=185, length=20

Step 4: Configure the SSH Server to Connect the Radius Server and Authentication from Radius Server :

# yum -y install pam pam-devel gcc
# cd /tmp
# wget ftp://ftp.freeradius.org/pub/radius/pam_radius-1.4.0.tar.gz
# tar zxf pam_radius-1.4.0.tar.gz
# cd pam_radius-1.4.0
# ./configure
# make
# cp pam_radius_auth.so /lib/security/

** Modify the Pam File of sshd and passwd for the Radius Authentication--

# vi /etc/pam.d/sshd

## Add this Line at 2nd Line--

auth sufficient /lib/security/pam_radius_auth.so

---- save & quit (:wq) ----

# vi /etc/pam.d/passwd

## Add the line at 3rd Line--

password sufficient /lib/security/pam_radius_auth.so

---- save & quit (:wq) ----

# vi /etc/ssh/sshd_config

## Change or Uncomment Line Number 48

PubkeyAuthentication no

---- save & quit (:wq) ----

# mkdir /etc/raddb/
# cp /tmp/pam_radius-1.4.0/pam_radius_auth.conf /etc/raddb/server
# vi /etc/raddb/server

## # Radius Server IP address           Secret                                   Timeout
<Radius-Server-IP> <Secret-Key-of-Radius-Server> 10

---- save & quit (:wq) ----

# service sshd restart
# useradd testuser

Note: Which Users will be authenticate from the Radius Server, those users should be there in the Radius Server Database and the User must exist on the SSH Server as well but no password has to be set on the SSH Server for the user, the password will be set at the database of the Radius Server.

** For Example as per the Doc:
user: testuser
pass: User_Password

# ssh testuser@<SSH-Server-IP>
Password: User_Password

** You should able to login now!

How to Install SSHFS on Centos/RHEL/Ubuntu

Install SSHFS on Centos/RHEL/Ubuntu

** What is SSHFS?

SSHFS is a filesystem based on the SSH File Transfer Protocol (SFTP). On remote side we just need to install SSH server, Since most of SSH servers already support this, there are nothing to do on remote server except installing SSH server. On client side we need to install fuse sshfs packages to mount remote filesystem. Newer version of SSHFS uses FUSE.
We Can user it as Alternative of NFS.

** Features of SSHFS:

1. Based on FUSE (Best userspace filesystem framework for linux)
2. Multithreading: more than one request can be on it’s way to the server
3. Allowing large reads (max 64k)
4. Caching directory contents

** Requirement:

1. 2 Centos/Ubuntu Server
2. SSH Key Authentication on the Servers

Step 1: Stop the IPTables and Selinux, and Update the Date Time on the Servers and SSH Authentication on the Servers:

# service iptables stop
# chkconfig iptables off

# vi /etc/sysconfig/selinux

SELINUX=disabled ###(Change enabled to disabled)

--- save & quit (:wq) ---

On Server 1:
# ssh-keygen -t rsa (Enter 3 Times)
# ssh-keygen -t dsa (Enter 3 Times)
# cd /root/.ssh
# cat id_rsa.pub >>authorized_keys
# cat id_dsa.pub >>authorized_keys

On Server 2:
# ssh-keygen -t rsa (Enter 3 Times)
# ssh-keygen -t dsa (Enter 3 Times)
# cd /root/.ssh
# cat id_rsa.pub >>authorized_keys
# cat id_dsa.pub >>authorized_keys

** Now Open the authorized_keys file on both Server and Paste the Server 1's Key to Server 2's authorized_keys File and vice-versa.

# service ntpd restart
# ntpdate pool.ntp.org
# chkconfig ntpd on
# init 6

Step 2: Install FUSE-SSHFS :

For CentOS/RHEL users, Fuse SSHFS is available under epel repository, So make sure you have install epel repository in your system. Now execute following command to install it.

On CentOS/RHEL:

# yum -y install epel-release
# yum install -y fuse-sshfs

On Ubuntu & Dabian:

$ sudo apt-get update
$ sudo apt-get install sshfs

Step 3: Mount Remote Directory :

Lets mount remote server directory using sshfs, make sure remote system has running ssh server with proper ssh connectivity from your system.
First create a mount point:

# mkdir /mntssh

Lets mount the remote directory. For this example we are mounting /home/remoteuser directory from x.x.x.x (remote.example.com) system to our local system.

# sshfs remoteuser@remote.example.com:/home/remoteuser /mntssh

[Sample output]

The authenticity of host 'remote.example.com (x.x.x.x)' can't be established.
RSA key fingerprint is 77:85:9e:ff:de:2a:ef:49:68:09:9b:dc:f0:f3:09:07.
Are you sure you want to continue connecting (yes/no)? yes
remoteuser@remote.example.com's password: yes

Step 4: Verify Mount :

After mounting remote filesystem on local mount point, verify it by running mount command.

# mount

/dev/mapper/vg_svr1-lv_root on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw)
/dev/sda1 on /boot type ext4 (rw)
remoteuser@remote.example.com:/home/remoteuser on /mntssh type fuse.sshfs (rw,nosuid,nodev)

Also naviate to your mount point, you will see files there from remote system

# cd /mntssh
# ls

Step 5: Mount Directory on System Boot :

If you want to mount remote filesystem automatically each time when your system reboots, Add following entry to /etc/fstab file. Make sure you have have key based ssh setup between remote and local system.

# vi /etc/fstab

remoteuser@remote.example.com:/home/remoteuser /mntssh fuse.sshfs defaults 0 0

--- save & quit (:wq) ---

Step 6: Unmount Directory :

If your work is over and you don’t need anymore the mounted directory, Simply unmount is using following command.

# umount /mntssh

How to Import SSL to the Existing Openfire Server in Linux Server

How to import SSL in the Existing Openfire Installation

What is Openfire?

Openfire is a real time collaboration (RTC) server licensed under the Open Source Apache License. It uses the only widely adopted open protocol for instant messaging, XMPP (also called Jabber).

Step 1: Put the Keys and Certificates:

Put the Cert and the Key and the CA Cert in the /etc/ssl/ Directory

# ll /etc/ssl/

-rw-r--r--  1 root root  4795 Aug  1 11:39 ca-bundle.crt
-rw-r--r--  1 root root  1838 Aug  1 11:39 ca-cert.crt
-rw-r--r--  1 root root  1704 Aug  1 11:39 ca-cert.key

Step 2: Create a Init Script for Run Openfire Run as a Service:

# vi /etc/init.d/openfire

#!/bin/bash
# description: Openfire Service Status
# processname: openfire
# chkconfig: 234 20 80
OPENFIRE_HOME=/opt/openfire

case $1 in
start)
sh $OPENFIRE_HOME/bin/openfire start
;;
stop)
sh $OPENFIRE_HOME/bin/openfire stop
;;
restart)
sh $OPENFIRE_HOME/bin/openfire restart
;;
status)
sh $OPENFIRE_HOME/bin/openfire status
;;
esac
exit 0

---- save & quit (:wq) ----

# chmod 755 /etc/init.d/openfire

Step 3: Create a Shell Script for Importing the Certs  keys to the JAVA Platform:

# vi /mnt/key-import.sh

### Add these lines

JavaDir="/opt/openfire/resources/security" ### Openfire Installation Directory for Store the Imported Keys
PASS="changeit" ### SSl Exportable & Openfire Admin Certificate Stores Passord
cert="ca-cert" ### Cert Name only
certdir="/etc/ssl" ### Cert Directory
tmp="/root" ### Temporary Folder
ca="/etc/ssl/ca-bundle.crt" ### CA Cert Name

test -e "${JavaDir}/truststore" && rm -f "${JavaDir}/truststore"  ### Checking if there is anything stored already in trustore
test -e "${JavaDir}/keystore" && rm -f "${JavaDir}/keystore"  ### Checking if there is anything stored already in keystore

service openfire stop
cat "${certdir}/${cert}.crt" "${ca}" > ${tmp}/"combined.crt"
keytool -import -trustcacerts -storepass $PASS -alias "StartSSL Class 2" -file "${ca}" -keystore "${JavaDir}/truststore"
openssl pkcs12 -export -in "${tmp}/combined.crt" -inkey "${certdir}/${cert}.key" -out "${tmp}/${cert}.p12" -name "${cert}" -CAfile "${ca}" -passout pass:"${PASS}"
keytool -importkeystore -deststorepass "$PASS" -srcstorepass "$PASS" -destkeystore "${JavaDir}/keystore" -srckeystore "${tmp}/${cert}.p12" -srcstoretype PKCS12 -alias "${cert}"
chmod 640 "${JavaDir}/truststore" "${JavaDir}/keystore"
chown openfire:openfire "${JavaDir}/truststore" "${JavaDir}/keystore"
service openfire start

---- save & quit (:wq) ----

# useradd -s /sbin/nologin openfire
# chown -Rf openfire:openfire /opt/openfire
# chmod -Rf 775 /opt/openfire
# vi /etc/sudoers

### Add at last of the File

openfire  ALL=(ALL)       NOPASSWD:ALL

---- save & quit (:wq) ----

N.B: After creating the openfire User can run the Key Import Script, then the Keys will be imported to the Openfire

# sh /mnt/key-import.sh
# ll /opt/openfire/resources/security

-rw-r----- 1 openfire openfire 6117 Aug  1 12:35 keystore
-rw-r----- 1 openfire openfire 1309 Aug  1 12:35 truststore

Step 4: Now login into the Openfire Admin Panel and Do the Rest:

http://<server-ip>:9090
User: admin
Pass: password

Click on TLS/SSL Certificates --> Give the Password that has been Used in the Script to Every Password Section Here one by one --> Save Settings (one by one) --> Done.

Step 5: Login to the Server via SSH and Shutdown Openffire Properly and then Start again:

# service openfire stop
# ps -ef |grep java

## Kill all the Processes that are running for Java

# kill -9 <PID>

Then statr the Openfire Again

# service openfire start

How to Install SVN With WebSVN (Web Panel) in Centos/RHEL 6.X

Install SVN With WebSVN on CentOS/RHEL 6.X

What is SVN?

Apache Subversion (often abbreviated SVN, after the command name svn) is a software versioning and revision control system distributed as free software under the Apache License. Software developers use Subversion to maintain current and historical versions of files such as source code, web pages, and documentation.

What is WebSVN?

WebSVN offers a view onto your subversion repositories that’s been designed to reflect the Subversion methodology. You can view the log of any file or directory and see a list of all the files changed, added or deleted in any given revision. You can also view the differences between two versions of a file so as to see exactly what was changed in a particular revision.

Requirements:

1. Apache
2. Subversion
3. php
4. WebSVN

Step 1: Stop the IPTables and Selinux, and Update the Date Time on the Server :

# service iptables stop
# chkconfig iptables off

# vi /etc/sysconfig/selinux

SELINUX=disabled ###(Change enabled to disabled)

--- save & quit (:wq) ---

# service ntpd restart
# ntpdate pool.ntp.org
# chkconfig ntpd on
# init 6

Step 2: Install & Configure SVN/Subversion with Apache :

A. Install Required Packages:

# yum install -y mod_dav_svn subversion svn httpd httpd-devel php

B. Create subversion.conf file:

# vi /etc/httpd/conf.d/subversion.conf

### add these lines ###

LoadModule dav_svn_module     modules/mod_dav_svn.so
LoadModule authz_svn_module   modules/mod_authz_svn.so

<location /repos>
DAV svn
SVNParentPath /var/www/svn/Repos
AuthType Basic
AuthName "Authorization Realm"
AuthUserFile /var/www/svn/secure/svn-users
AuthzSVNAccessFile /var/www/svn/secure/svn-access-control
Require valid-user

</location>

--- save & quit (:wq) ---

C. Create SVN Directory Tree:

# mkdir -p /var/www/svn/{Repos,secure}
# touch /var/www/svn/secure/svn-access-control
# touch /var/www/svn/secure/svn-users
# service httpd restart

Step 3: Configure some Test Repo & create User for SVN :

A. Create Repo and User:

# cd /var/www/svn/Repos
# svnadmin create testrepo
# chmod -Rf 777 testrepo
# htpasswd -cm /var/www/svn/secure/svn-users testuser (after that give password for "testuser" twice)

B. Modify svn-access-control for Repos Permisions:

# vi /var/www/svn/secure/svn-access-control

### add these lines
[groups]

admin = testuser
testrepo = testuser

[/]
@admin = rw

[testrepo:/]
@testrepo = rw

--- save & quit (:wq) ---

# service svnserve restart

### Check the Svn repo with the url: http://<ip-of-server>/repos/testrepo
username: testuser
password: (Password)

C. update the Repo to Revision 1

# mkdir -p /mnt/svn-structure-template/{trunk,branches,tags}
# svn import -m 'Initial import' /mnt/svn-structure-template/ http://localhost/repos/testrepo

Step 4: Install and Configure WebSVN :

# cd /var/www/html
# wget http://websvn.tigris.org/files/documents/1380/49057/websvn-2.3.3.zip
# unzip websvn-2.3.3.zip
# mv websvn-2.3.3 websvn
# cd /var/www/html/websvn/include
# cp distconfig.php config.php
# vi config.php

### add these lines

// Configure these lines if your commands aren't on your path.
//
$config->setSVNCommandPath('/usr/bin'); // e.g. c:\\program files\\subversion\\bin
$config->setDiffPath('/usr/bin');
// For syntax colouring, if option enabled...
$config->setEnscriptPath('/usr/bin');
$config->setSedPath('/bin');
// For delivered tarballs, if option enabled...
$config->setTarPath('/bin');
// For delivered GZIP'd files and tarballs, if option enabled...
$config->setGZipPath('/bin');
//
$config->parentPath('/svn/');
$extEnscript[".pl"] = "perl";
$extEnscript[".py"] = "python";
$extEnscript[".sql"] = "sql";
$extEnscript[".java"] = "java";
$extEnscript[".html"] = "html";
$extEnscript[".xml"] = "html";
$extEnscript[".thtml"] = "html";

Step 1: Download Archive File

Download latest version of java from http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html.

For 64 Bit –
# cd /opt/
# wget http://download.oracle.com/otn-pub/java/jdk/7u67-b01/jdk-7u67-linux-x64.tar.gz?AuthParam=1410461115_7bfe6685f15c82dcaaedb31561201f2b

Note: In any case if above command failed to download and you need to download java through Linux terminal, watch below screen cast ( http://screencast.com/t/wf9bQ0XjDPxT ), You are required a graphical browser.

After completing download, Extract archive using following command. Use archive file as per your system configuration. For this example we are using 32 bit machine.

# tar -zxvf jdk-7u67-linux-x64.gz

Step 2: Install JAVA using Alternatives

After extracting java archive file, we just need to set up to use newer version of java using alternatives. Use the following commands to do it.

# cd /opt/jdk1.7.0_65/
# alternatives --install /usr/bin/java java /opt/jdk1.7.0_65/bin/java 2
# alternatives --config java

There are 4 programs which provide 'java'.

  Selection    Command
-----------------------------------------------
*  1           /usr/lib/jvm/jre-1.6.0-openjdk/bin/java
 + 2           /opt/jdk1.7.0_55/bin/java
   3           /opt/jdk1.7.0_60/bin/java
   4           /opt/jdk1.7.0_65/bin/java

Enter to keep the current selection[+], or type selection number: 4 [Press Enter]

Now you may also required to setup javac and jar commands path using alternatives

# alternatives --install /usr/bin/jar jar /opt/jdk1.7.0_65/bin/jar 2
# alternatives --install /usr/bin/javac javac /opt/jdk1.7.0_65/bin/javac 2
# alternatives --set jar /opt/jdk1.7.0_65/bin/jar
# alternatives --set javac /opt/jdk1.7.0_65/bin/javac
Step 3: Check JAVA Version

Use following command to check which version of java is currently being used by system.

# java -version
java version "1.7.0_65"
Java(TM) SE Runtime Environment (build 1.7.0_65-b17)
Java HotSpot(TM) Client VM (build 24.60-b09, mixed mode)


Step 4: Setup Environment Variables

Most of java based application’s uses environment variables to work. Use following commands to set up it.

Setup JAVA_HOME Variable
# export JAVA_HOME=/opt/jdk1.7.0_65
Setup JRE_HOME Variable
# export JRE_HOME=/opt/jdk1.7.0_65/jre
Setup PATH Variable
