ProFTPD : Installing and Configuring in Ubuntu/Debian

ProFTPD (Pro File Transfer Protocol Daemon) is an open source FTP server and is compatible with both Microsoft Windows and Linux type operating systems. The main motive of Pro-FTPD is to provide a mechanism to setup FTP server that is more rich in features and highly secure and easy to setup. To install and configure the Pro-FTPD follow these simple steps. 

 

Steps

 

1) Install proftpd using apt-get command

$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get install proftpd

 

2) Add this line in /etc/shells file

/bin/false

 

3) Create a /home/FTP-shared directory

cd /home
 sudo mkdir FTP-shared

 

4) Create a user which will be used only for ftp access.

sudo useradd any_user_name -p your_password -d /home/FTP-shared -s /bin/false
 sudo passwd userftp

 

5) Now we have to set the good permissions for these directories

cd /home
sudo chmod 755 FTP-shared

 

6) Provide access of created shared directory to created FTP user 

chown -R (FTPUSER) /(path)/(to_your_ftp)/

 

7) Restart proftpd service

sudo /etc/init.d/proftpd restart

JBOSS Web Server : Install JBoss on Linux Machine

In the previous post we have seen how to install and setup MySQL on the linux machine. This post will guide you to install JBoss web server. JBoss is web server built on Apache and Tomcat 

Install JBoss Web Server

1) Download zipped JBoss 7.1.x in /opt directory

# wget http://download.jboss.org/jbossas/7.1/jboss-as-7.1.1.Final/jboss-as-7.1.1.Final.tar.gz -P /var/tmp
2) Extract using tar command 
# tar -zxf /var/tmp/jboss-as-7.1.1.Final.tar.gz -C /opt
3) Remove the zipped file using rm command
# rm -f /var/tmp/jboss-as-7.1.1.Final.tar.gz
4) Running JBOSS as root is a security risk. Run JBoss using a dedicated system user which will run the JBoss server using the sudo powers.
# useradd -r jboss -d /opt/jboss-as-7.1.1.Final

# chown jboss: -R /opt/jboss-as-7.1.1.Final
5) Enable access to JBoss interface by editing standalone.xml
# vim /opt/jboss-as-7.1.1.Final/standalone/configuration/standalone.xml
6) Change local IP (127.0.0.1) address to public IP of machine
<interface name="management">
   <inet-address value="${jboss.bind.address.management:127.0.0.1}"/>
</interface>
<interface name="public">
   <inet-address value="${jboss.bind.address:127.0.0.1}"/>
</interface>
7) Set-up Jboss to run as a service
# cp /opt/jboss-as-7.1.1.Final/bin/init.d/jboss-as-standalone.sh /etc/init.d/jboss
# chmod +x /etc/init.d/jboss
# mkdir /etc/jboss-as
8) Create configuration file 
# vim /etc/jboss-as/jboss-as.conf
and add the following configuration parameters
JBOSS_HOME=/opt/jboss-as-7.1.1.Final
JBOSS_CONSOLE_LOG=/var/log/jboss-console.log
JBOSS_USER=jboss
9) Start JBoss service
# service jboss start
10) Done
