FTP sharing

File Sharing Protocol

ports used

ftp-data 20/tcp

ftp-data 20/udp

ftp 21/tcp

ftp 21/udp

files are /etc/vsftpd/vsftpd.conf

We have two type of access modes anonymous and user mode

In anonymous we can enter without password & in user mode we should enter password to get access

In anonymous we mode we will be sharing /var/ftp/pub directory & in usermode we will be sharing coresponding users home directory

In anonymous mode users will normally have only read permission if we need to give write permission we need to create a directory inside the /var/ftp and change the context to public_content_rw_t and set the acl of that directory to ftp user to enable anonymous user entry we need to enable following lines as yes

anonymous_enable=YES

write_enable=YES anon_upload_enable=YES

anon_mkdir_write_enable=YES

give the write permission as per need we need to set the sebool also to get it right

getseboot-a | grep ftp

 

To enable user mode entry just set no to all the anonymous settings and set yes to

local_enable=YES and we need to set needed sebool getsebool -a | grep ftp

LAMP installation and configuration

#Configuring LAMP-LINUX APACHE MYSQL PHP
#1.LINUX here i use machine preinstalled with rhel 6 desktop kde gnome packages
#installing the LAMP to /LAMP folder /LAMP/http /LAMP/mysql /LAMP/php
#First remove the installed packages
#yum erase http*
#yum erase mysql*
yum erase php*

#installing and configuring APACHE----

#The Package we use are httpd-2.4.3.tar.gz

-->tarxvf httpd-2.4.3.tar.gz
-->cd httpd-2.4.3
-->./configure --prefix=/LAMP/http/ --enable-module=so

#Now an error will occur asking for apr version-1.4 or greater

#Download the apr from http://apr.apache.org/download.cgi
#here i use apr-1.4.6.tar.gz apr-util-1.4.1.tar.gz

-->tar xvf apr-1.4.6.tar.gz
-->tar xvf apr-util-1.4.1.tar.gz
-->mv apr-1.4.6 /lamp/http/httpd-2.4.3/srclib/apr

-->./configure --prefix=/LAMP/http/ --enable-module=so--enable-rewrite=shared --with-included-apr

##now if it will ask for pcre packages

-->yum install -y pcre*
-->./configure --prefix=/LAMP/http/ --enable-module=so--enable-rewrite=shared --with-included-apr

-->make
-->make install
