Step 1 :

Go to the following link and get your access key.
Get Ksplice Uptrack Access Key

Step 2 :

nano /etc/apt/sources.list.d/ksplice.list

Add the following lines to the file ksplice.list.

deb http://www.ksplice.com/apt oneiric ksplice
deb-src http://www.ksplice.com/apt oneiric ksplice

Step 3 :
Replace INSERT_ACCESS_KEY with your access key. Please use the same
access key for all of your systems:

sudo apt-get install ca-certificates
wget -N https://www.ksplice.com/apt/ksplice-archive.asc
sudo apt-key add ksplice-archive.asc
echo 'uptrack uptrack/accesskey string INSERT_ACCESS_KEY' | sudo debconf-set-selections
sudo apt-get update
sudo apt-get install uptrack

Step 4 :

nano /etc/uptrack/uptrack.conf

Change the following as is :
autoinstall = yes

Step 5 :

uptrack-upgrade -y

Remarks :

Ksplice Uptrack updates your running kernel in memory only. Enabling autoinstall does not mean the Uptrack client itself is automatically upgraded. You will be notified via e-mail when a new Uptrack client is available, and it can be upgraded through your package manager.

uptrack-upgrade -y

That's all! See you.

Hardening SSH

The official port of SSH is 22. You can change it to any port that between 1024 and 65535. You can do it at the router or firewall and you can do it at the configure file of SSH at /etc/ssh/sshd_config. You are recommended to disable the root account login via SSH even you are using Ubuntu.

Port 65535
PermitRootLogin no

sudo /etc/init.d/sshd restart

Block all failed attempts

You are also required to install Fail2Ban in order to block all several time failed attempts.

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install fail2ban

Change the setting at /etc/fail2ban/jail.conf when necessary.

Restart the fail2ban after the changes.

HOWTO : Highest secured Hiawatha Web Server 7.4 on Ubuntu 10.10 Server

Hiawatha is a very secure and fast web server in the market. It supports PHP, Perl, Python and Ruby. It is also very lightweight, easy to configure and setup too. For the performance, please refer to the study of SaltwaterC at here.

This tutorial is writing for setting up the highest secured web server. Please also to apply the "Optional" steps mentioned below for making the highest secured web server.

Prerequisite

Select OpenSSH and Mail Server when installing Ubuntu Server 10.10.

Update the fresh install system to the latest status.

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

If the kernel or kernel modules have been updated, you are required to reboot your system before going further.

Step 1 - Installation of PHP5 and MySQL

sudo apt-get install mysql-server mysql-client php5-cgi php5 php5-cli php5-mysql php5-curl php5-gd php5-idn php-pear php5-imagick php5-imap php5-mcrypt php5-memcache php5-ming php5-ps php5-pspell php5-recode php5-snmp php5-sqlite php5-tidy php5-xmlrpc php5-xsl php5-xcache php5-suhosin php5-ffmpeg apache2-utils mini-httpd

Step 1a - Installation of PHP5 and MariaDB (Alternative)

Since MySQL is now owned by Oracle, the developers of previous MySQL reformed and developed MariaDB under GPL v2. It is compatible to MySQL and running much faster than MySQL too. You can use MariaDB as alternative. The commands and API are the same, such as "mysql -u root -p".

Prepare for installation of MariaDB
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 1BB943DB

sudo nano /etc/apt/sources.list.d/mariadb.list

Append the following lines.

deb http://mirrors.xmission.com/mariadb/repo/5.2/ubuntu maverick main
deb-src http://mirrors.xmission.com/mariadb/repo/5.2/ubuntu maverick main

Save the change and install the following.

sudo apt-get update

sudo apt-get install mariadb-server mariadb-client php5-cgi php5 php5-cli php5-mysql php5-curl php5-gd php5-idn php-pear php5-imagick php5-imap php5-mcrypt php5-memcache php5-ming php5-ps php5-pspell php5-recode php5-snmp php5-sqlite php5-tidy php5-xmlrpc php5-xsl php5-xcache php5-suhosin php5-ffmpeg apache2-utils mini-httpd

** You can also replace your MySQL to MariaDB in this way. The MySQL will be uninstall automatically. You can also use the my.cnf of MySQL without any problem or replace by the new one.

Step 2 - Installation of Hiawatha

Install required dependenices for Hiawatha.

sudo apt-get install libc6-dev libssl-dev dpkg-dev debhelper fakeroot libxml2-dev libxslt1-dev

Download the latest version of Hiawatha (the current version at this writing is 7.4).

wget http://www.hiawatha-webserver.org/files/hiawatha-7.4.tar.gz
tar -xzvf hiawatha-7.4.tar.gz
cd hiawatha-7.4

./configure
make deb

cd ..

sudo dpkg -i hiawatha_7.4_amd64.deb

or

sudo dpkg -i hiawatha_7.4_i386.deb

Step 3 - Configure PHP5 (Optional for security only)

The following settings are for making PHP5 more secure.

sudo nano /etc/php5/cgi/php.ini

Make changes as is.

cgi.rfc2616_headers = 1

zlib.output_compression = On
zlib.output_compression_level = 6

display_errors = Off
log_errors = On
allow_url_fopen = Off
safe_mode = On
expose_php = Off
enable_dl = Off
disable_functions = system, show_source, symlink, exec, dl, shell_exec, passthru, phpinfo, escapeshellarg, escapeshellcmd

*some PHP applications may require safe_mode = off

Step 4 - Configure php-fcgi (PHP's FastCGI)

sudo nano /etc/hiawatha/php-fcgi.conf

Uncomment the following line and change it as is.

Server = /usr/bin/php5-cgi ; 127.0.0.1:2005 ; www-data ; /etc/php5/cgi/php.ini

sudo php-fcgi -c /etc/hiawatha/php-fcgi.conf

If you make any change on php-fcgi.conf, make sure to restart it by the following commands.

sudo php-fcgi -k -c /etc/hiawatha/php-fcgi.conf
sudo php-fcgi -c /etc/hiawatha/php-fcgi.conf

Step 5 - Configure Hiawatha (Part 1)

sudo nano /etc/hiawatha/hiawatha.conf

Uncomment ServerId at GENERAL SETTINGS.

ServerId = www-data

Uncomment the following entries at BINDING SETTINGS.

Binding {
   Port = 80
#   Interface = 127.0.0.1
   MaxKeepAlive = 30
   TimeForRequest = 3,20
}

Step 5a (Optional for security purpose) :

Add the following line at the GENERAL SETTINGS.

ConnectionsTotal = 1000
ConnectionsPerIP = 30
SystemLogfile = /var/log/hiawatha/system.log
GarbageLogfile = /var/log/hiawatha/garbage.log
ExploitLogfile = /var/log/hiawatha/exploit.log

LogFormat = extended
ServerString = Apache
CGIwrapper = /usr/sbin/cgi-wrapper

Make changes for the following entries at BANNING SETTINGS.

BanOnGarbage = 300
BanOnMaxPerIP = 300
BanOnMaxReqSize = 300
BanOnTimeout = 300
KickOnBan = yes
RebanDuringBan = yes

BanOnDeniedBody = 300
BanOnSQLi = 300
BanOnFlooding = 30/1:300
BanlistMask = deny 192.168.0.0/24, deny 127.0.0.1

KickOnBan = yes
ReconnectDelay = 3

Step 5b :

The entries at COMMON GATEWAY INTERFACE (CGI) SETTINGS should be looking like this.

CGIhandler = /usr/bin/perl:pl
CGIhandler = /usr/bin/php5-cgi:php
CGIhandler = /usr/bin/python:py
CGIhandler = /usr/bin/ruby:rb
CGIhandler = /usr/bin/ssi-cgi:shtml
CGIextension = cgi

FastCGIserver {
   FastCGIid = PHP5
   ConnectTo = 127.0.0.1:2005
   Extension = php, php5
   SessionTimeout = 30
}

Step 5c :

Add the following line at VIRTUAL HOSTS.

Include /etc/hiawatha/enable-sites/

*Make sure the make a directory enable-sites under /etc/hiawatha.

sudo mkdir /etc/hiawatha/enable-sites

Step 6 - Configure Hiawatha (Part 2)

If your domain is mysite.com, you are required to create a file namely mysite.com and place it under /etc/hiawatha/enable-sites/mysite.com.

VirtualHost {
   Hostname = www.mysite.com, mysite.com
   WebsiteRoot = /var/www/mysite
   StartFile = index.php
   AccessLogfile = /var/log/hiawatha/access.log
   ErrorLogfile = /var/log/hiawatha/error.log
   TimeForCGI = 15
#   UseFastCGI = PHP5
#   UseToolkit = banshee
   DenyBody = ^.*%3Cscript.*%3C%2Fscript%3E.*$
   ExecuteCGI = yes
   PreventCSRF = yes
   PreventSQLi = yes
   PreventXSS = yes
   DenyBot = Googlebot:/
   DenyBot = twiceler:/
   DenyBot = MSNBot:/
   DenyBot = yahoo:/
   DenyBot = BaiDuSpider:/
   DenyBot = Ask:/
   DenyBot = Yahoo! Slurp:/
   DenyBot = Sogou web spider:/
   DenyBot = Sogou-Test-Spider:/
   DenyBot = Baiduspider+:/
   DenyBot = Yandex:/
   DenyBot = UniversalFeedParser:/
   DenyBot = Mediapartners-Google:/
   DenyBot = Sosospider+:/
   DenyBot = YoudaoBot:/
   DenyBot = ParchBot:/
   DenyBot = Curl:/
   DenyBot = msnbot:/
   DenyBot = NaverBot:/
   DenyBot = taptubot:/
   WrapCGI = jail_mysite
}

Step 7 - Configure Hiawatha (Part 3) (Optional for security purpose)

sudo nano /etc/hiawatha/cgi-wrapper.conf

CGIhandler = /usr/bin/perl
CGIhandler = /usr/bin/php5-cgi
CGIhandler = /usr/bin/python
CGIhandler = /usr/bin/ruby
CGIhandler = /usr/bin/ssi-cgi

Wrap = jail_mysite ; /var/www/mysite ; www-data:www-data

Step 8 - Configure Apparmor (Optional for security purpose)

Execute the following command and then let the web site running for a while, maybe a week or so.

sudo aa-genprof hiawatha

About one week later or the web page/site is misbehaving, issue the following command to update the profile. Remember to reload the profile after the command has been issued.

sudo aa-logprof

Or, if you are impatient, you can edit the following file instead.

sudo nano /etc/apparmor.d/usr.sbin.hiawatha

The content of usr.sbin.hiawatha should look like this or make it look like this.

# Last Modified: Thu Jun 3 01:52:13 2010
#include

/usr/sbin/hiawatha {
   #include
   #include
   #include
   #include

   capability chown,
   capability dac_override,
   capability fowner,
   capability fsetid,
   capability setgid,
   capability setuid,

   /bin/dash rix,
   owner /etc/hiawatha/ r,

   /usr/sbin/sendmail rix,
   /usr/share/ r,
   /usr/share/** r,
   /var/www/ r,
   /var/www/** rwk,
   /var/lib/ r,
   /var/lib/** rw,
   /var/lib/hiawatha/** rw,
   owner /var/log/hiawatha/** w,
   /var/log/hiawatha/** r,
   owner /var/run/ r,
   owner /var/run/** w,
   /var/run/** r,
   /var/spool/postfix/** rw,
   /var/spool/postfix/pid/** wk,
}

Make the profile in enforce mode (activate the above settings).

sudo aa-enforce hiawatha

If you have change some settings, you should reload the profile.

sudo apparmor_parser -r < /etc/apparmor.d/usr.sbin.hiawatha

If you want to disable this profile.

sudo ln -s /etc/apparmor.d/usr.sbin.hiawatha /etc/apparmor.d/disable/
sudo apparmor_parser -R < /etc/apparmor.d/usr.sbin.hiawatha

If you want to re-enable this profile after it has been disabled.

sudo rm /etc/apparmor.d/disable/usr.sbin.hiawatha
sudo apparmor_parser -r < /etc/apparmor.d/usr.sbin.hiawatha

Step 9 - Enhance the security of cgi-wrapper (Optional for security purpose)

Now, your hiawatha is very secure but I would like to make it more secure.

sudo apt-get install libcap2-bin

Apply Capabilities on cgi-wrapper.

sudo chmod u-s /usr/sbin/cgi-wrapper
sudo setcap cap_setgid,cap_setuid+ep /usr/sbin/cgi-wrapper

The result of getcap :

sudo getcap /usr/sbin/cgi-wrapper

It will display :
/usr/sbin/cgi-wrapper = cap_setgid,cap_setuid+ep

Step 10 - Configure logwatch (Optional)

HOWTO : Logwatch for Hiawatha on Ubuntu

Step 11 - Change the ownership of the log files

cd /var/log/hiawatha
sudo chown www-data:www-data access.log
sudo chown www-data:www-data error.log
sudo chown www-data:www-data exploit.log

* "php-fcgi.log" and "system.log" leave them untouched (root:root).

Step 11a - Change ownership of all directories and files at the /var/www/mysite

Put the web application files to /var/www/mysite and then change the ownership of all directories and files under /var/www/mysite to root:root.

cd /var/www/mysite
sudo chown -R root:root *

Step 12 - Start, Stop and Restart Hiawatha

sudo /etc/init.d/hiawatha start
sudo /etc/init.d/hiawatha stop
suod /etc/init.d/hiawatha restart

Step 13 - Performance tuning for MySQL or MariaDB (Optional)

You can fine tune the MySQL or MariaDB as per this link.

Step 14 - Performance tuning for Ubuntu (Optional)

You can fine tune the Ubuntu Server as per this link.

Remarks :

If you encounter "500 Internal Server Error", you may consider to make the Apparmor to "Complain mode".

sudo aa-complain hiawatha

After several days browsing the website, you may consider to turn the Apparmor to "Enforce mode".

sudo aa-logprof

sudo aa-enforce hiawatha

It is because the captioned usr.sbin.hiawatha may not 100% work for you.

That's all! See you.

}

Make the profile in enforce mode (activate the above settings).

sudo aa-enforce hiawatha

If you have change some settings, you should reload the profile.

sudo apparmor_parser -r < /etc/apparmor.d/usr.sbin.hiawatha

If you want to disable this profile.

sudo ln -s /etc/apparmor.d/usr.sbin.hiawatha /etc/apparmor.d/disable/
sudo apparmor_parser -R < /etc/apparmor.d/usr.sbin.hiawatha

If you want to re-enable this profile after it has been disabled.

sudo rm /etc/apparmor.d/disable/usr.sbin.hiawatha
sudo apparmor_parser -r < /etc/apparmor.d/usr.sbin.hiawatha

Step 9 - Enhance the security of cgi-wrapper (Optional for security purpose)

Now, your hiawatha is very secure but I would like to make it more secure.

sudo apt-get install libcap2-bin

Apply Capabilities on cgi-wrapper.

sudo chmod u-s /usr/sbin/cgi-wrapper
sudo setcap cap_setgid,cap_setuid+ep /usr/sbin/cgi-wrapper

The result of getcap :

sudo getcap /usr/sbin/cgi-wrapper

It will display :
/usr/sbin/cgi-wrapper = cap_setgid,cap_setuid+ep

Step 10 - Configure logwatch (Optional)

HOWTO : Logwatch for Hiawatha on Ubuntu

Step 11 - Start, Stop and Restart Hiawatha

sudo /etc/init.d/hiawatha start
sudo /etc/init.d/hiawatha stop
suod /etc/init.d/hiawatha restart

That's all! See you.

HOWTO : Highest secured Hiawatha Web Server 6.19 on Ubuntu 9.10 Server

Hiawatha is a web server that equipped with a lot of security features. It is developed by Hugo Leisink since 2002. 

Hiawatha supports PHP, Perl, Python and Ruby. It is a lightweight and fast as well as secured web server.

Installation of Linux, Hiawatha, MySQL and PHP - LHMP

Step 0 - Install Ubuntu 9.10

Install Ubuntu 9.10 Server and OpenSSH.  If your web application requires email function, you should also install Mail Server also.

Make sure you have perform the following commands at the terminal (or console).

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

If the kernel or kernel modules have been updated, you should reboot your computer/server.

Step 1 - Install PHP5 and MySQL

sudo apt-get install mysql-server mysql-client php5-cgi php5 php5-cli php5-mysql php5-curl php5-gd php5-idn php-pear php5-imagick php5-imap php5-mcrypt php5-memcache php5-mhash php5-ming php5-ps php5-pspell php5-recode php5-snmp php5-sqlite php5-tidy php5-xmlrpc php5-xsl

*Note : some modules will not be required, such as php5-sqlite and php5-snmp.  If your web application requires them, make sure to install them.

Step 2 - Install Hiawatha

Download the current Hiawatha, 6.19 at this time of writing.

sudo wget http://www.hiawatha-webserver.org/files/hiawatha-6.19.tar.gz
tar -xzvf hiawatha-6.19.tar.gz
cd hiawatha-6.19

Install requires dependenices.

sudo apt-get install libc6-dev libssl-dev dpkg-dev debhelper fakeroot libxml2-dev libxslt1-dev

At the hiawatha-6.19 directory, build the Hiawatha deb package.

./configure
make deb

The deb package will be created at your home directory, such as /home/samiux.  You can install it now.

cd ..

For 64-bit system :
sudo dpkg -i hiawatha_6.19_amd64.deb

For 32-bit system :
sudo dpkg -i hiawatha_6.19_i386.deb

Step 3 - Configure PHP5

Edit the php.ini.

sudo nano /etc/php5/cgi/php.ini

Make change as is.

display_errors = Off
log_errors = On
allow_url_fopen = Off
safe_mode = On
expose_php = Off
enable_dl = Off
disable_functions = system, show_source, symlink, exec, dl, shell_exec, passthru, phpinfo, escapeshellarg, escapeshellcmd

*Note : some PHP application may requires safe_mode = Off.

Edit Hiawatha's php-fcgi.conf.

sudo nano /etc/hiawatha/php-fcgi.conf

Uncomment the following line.
Server = /usr/bin/php5-cgi ; 127.0.0.1:2005 ; www-data

Activate php-fcgi.

sudo php-fcgi -c /etc/hiawatha/php-fcgi.conf

If you make any change on php-fcgi.conf, make sure to restart it by following commands.

sudo php-fcgi -k -c /etc/hiawatha/php-fcgi.conf
sudo php-fcgi -c /etc/hiawatha/php-fcgi.conf

Step 4 - Configure Hiawatha

Edit the file hiawatha.conf.

sudo nano /etc/hiawatha/hiawatha.conf

Uncomment ServerId at GENERAL SETTINGS.
ServerId = www-data

Add the following line at the GENERAL SETTINGS. Apache compatible log file format.
LogFormat = extended
ExploitLogfile = /var/log/hiawatha/exploit.log
ServerString = Apache
CGIwrapper = /usr/sbin/cgi-wrapper

Uncomment the following entries at BINDING SETTINGS.
Binding {
   Port = 80
   MaxKeepAlive = 30
   TimeForRequest = 3,20
}

Uncomment all the entries at BANNING SETTINGS.
BanOnGarbage = 300
BanOnMaxPerIP = 60
BanOnMaxReqSize = 300
KickOnBan = yes
RebanDuringBan = yes
BanOnSQLi = 60
BanOnFlooding = 10/1:15
BanlistMask = allow 192.168.0.0/24

*Note : Make change to the Banlistmask in order to meet your network requirement.

Uncomment php5-cgi and CGIextension lines.
CGIhandler = /usr/bin/perl:pl
CGIhandler = /usr/bin/php5-cgi:php
CGIhandler = /usr/bin/python:py
CGIhandler = /usr/bin/ruby:rb
CGIhandler = /usr/bin/ssi-cgi:shtml
CGIextension = cgi

Uncomment all the entries of FastCGIserver and rename ConnectTo to 127.0.0.1:2005.

FastCGIserver {
   FastCGIid = PHP5
   ConnectTo = 127.0.0.1:2005
   Extension = php, php5
   SessionTimeout = 30
}

Optional - Create the following lines under URL TOOLKIT.

UrlToolkit {
   ToolkitID = CMS_common
   RequestURI isfile Return
   RequestURI exists Return
   Match ^/(favicon.ico|robots.txt|sitemap.xml)$ Return
   Match .*\?(.*) Rewrite /index.php?$1
   Match .* Rewrite /index.php
}

*Note : UrlToolkit is similar to Apache's mod_rewrite.

Create a VirtualHost for your site.

VirtualHost {
   Hostname = samiux.blogspot.com
   #Alias = /php_my_admin:/usr/share/phpmyadmin
   WebsiteRoot = /var/www/blog
   StartFile = index.php
   AccessLogfile = /var/log/hiawatha/blog_access.log
   ErrorLogfile = /var/log/hiawatha/blog_error.log
   TimeForCGI = 5
   #UseFastCGI = PHP5
   UseToolkit = CMS_common
   ExecuteCGI = yes
   PreventCSRF = yes
   PreventSQLi = yes
   PreventXSS = yes
   DenyBot = Googlebot:/
   DenyBot = twiceler:/
   DenyBot = MSNBot:/
   DenyBot = yahoo:/
   DenyBot = BaiDuSpider:/
   DenyBot = Ask:/
   DenyBot = Yahoo! Slurp:/
   DenyBot = Sogou web spider:/
   DenyBot = Sogou-Test-Spider:/
   DenyBot = Baiduspider+:/
   DenyBot = Yandex:/
   DenyBot = UniversalFeedParser:/
   DenyBot = Mediapartners-Google:/
   DenyBot = Sosospider+:/
   DenyBot = YoudaoBot:/
   DenyBot = ParchBot:/
   DenyBot = Curl:/
   DenyBot = msnbot:/
   DenyBot = NaverBot:/
   DenyBot = taptubot:/
   WrapCGI = jail
}

Configure cgi-wrapper.conf.
sudo nano /etc/hiawatha/cgi-wrapper.conf

Make changes to the file.
CGIhandler = /usr/bin/perl
CGIhandler = /usr/bin/php5-cgi
CGIhandler = /usr/bin/python
CGIhandler = /usr/bin/ruby
CGIhandler = /usr/bin/ssi-cgi

Wrap = jail ; /var/www ; www-data:www-data

*Note : DenyBot entries are optional.  If you do not want spiders and bots to crawl your site, you should enable it.  Those entries are examples only.  UseToolKit is also optional.

Make sure /var/log/hiawatha/blog exists (example) and its ownership is www-data.

If not, make it as is.
sudo chown -R www-data:www-data /var/log/hiawatha/blog

Restart Hiawatha.
sudo /etc/init.d/hiawatha restart

Now, make sure the ownership of access.log and error.log are www-data.  If not, make them as is.

sudo chown www-data:www-data /var/log/hiawatha/blog/*

Step 5 - Configure Apparmor (to make Hiawatha more safety)

Create Apparmor profile for Hiawatha.
sudo aa-genprof hiawatha

Edit the profile usr.sbin.hiawatha.
sudo nano /etc/apparmor.d/usr.sbin.hiawatha

Make the entries look like this.
# Last Modified: Thu Oct 1 10:00:57 2009
#include


/usr/sbin/hiawatha {

   /var/spool/postfix/public/pickup w,
   /var/www/ r,
   /var/www/** rw,
}

* suppose you are using postfix.

Make the profile in enforce mode (active).
sudo aa-enforce hiawatha

If you have change some settings, you should reload the profile.
sudo apparmor_parser -r < /etc/apparmor.d/usr.sbin.hiawatha

If you want to disable this profile.
sudo ln -s /etc/apparmor.d/usr.sbin.hiawatha /etc/apparmor.d/disable/
sudo apparmor_parser -R < /etc/apparmor.d/usr.sbin.hiawatha

If you want to re-enable this profile after it has been disabled.
sudo rm /etc/apparmor.d/disable/usr.sbin.hiawatha
sudo apparmor_parser -r < /etc/apparmor.d/usr.sbin.hiawatha

Step 6 - Improve the security of CGI-Wrapper

Now, your hiawatha is very secure but I would like to make it more secure.

sudo apt-get install libcap2-bin

Apply Capabilities on cgi-wrapper.
sudo chmod u-s /usr/sbin/cgi-wrapper
sudo setcap cap_setgid,cap_setuid+ep /usr/sbin/cgi-wrapper

The result of getcap :

sudo getcap /usr/sbin/cgi-wrapper

It will display :
/usr/sbin/cgi-wrapper = cap_setgid,cap_setuid+ep

Step 7 - logwatch configuration

LogWatch configuration as per Ubuntu 9.04

That's all.  See you!

HOWTO : Most secure web server (Hiawatha 6.17.1) on Ubuntu 9.04 Server

What is Hiawatha?

Hiawatha is a web server that developed by Hugo Leisink since 2002. Hiawatha is not as well known as Apache; however, it has some unique features that Apache lacks of. Apache requires some modules to do the security purpose, such as modsecurity and mod_rewrite. Hiawatha is already built-in. She can ban some bad traffic and bad activities on your web server. Her footprint is also small, that is 130kb, surprise?! She is the default web server for Austrumi and Puppy Linux.

Although the user manual at her official site is not detail enough (at the time of this writing), it is quite easy to configure and runs on a production server. There may be a bug at cgi-wrapper in Hiawatha 6.17.1 and it cannot be configured to run PHP5 in cgi-wrapper mode at the moment. However, perl is no problem.

Hiawatha runs MySQL and PHP great in cgi mode. It can run in Windows environment too (but not yet tried). This tutorial is going to show you how to configure Hiawatha to work with MySQL and PHP.

Installation of Linux, Hiawatha, MySQL and PHP - LHMP

Step 0 - Install Ubuntu 9.04

Install Ubuntu 9.04 Server and OpenSSH. If your web application requires email function, you should also install Mail Server also.

Make sure you have perform the following commands at the terminal (or console).

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

If the kernel or kernel modules have been updated, you should reboot your computer/server.

Step 1 - Install PHP5 and MySQL

sudo apt-get install mysql-server mysql-client php5-cgi php5 php5-cli php5-mysql php5-curl php5-gd php5-idn php-pear php5-imagick php5-imap php5-mcrypt php5-memcache php5-mhash php5-ming php5-ps php5-pspell php5-recode php5-snmp php5-sqlite php5-tidy php5-xmlrpc php5-xsl

*Note : some modules will not be required, such as php5-sqlite and php5-snmp. If your web application requires them, make sure to install them.

Step 2 - Install Hiawatha

Download the current Hiawatha, 6.17.1 at this time of writing.

sudo wget http://www.hiawatha-webserver.org/files/hiawatha-6.17.1.tar.gz
tar -xzvf hiawatha-6.17.1.tar.gz
cd hiawatha-6.17.1

Install requires dependenices.

sudo apt-get install libc6-dev libssl-dev dpkg-dev debhelper fakeroot libxml2-dev libxslt1-dev

At the hiawatha-6.17.1 directory, build the Hiawatha deb package.

./configure
make deb

The deb package will be created at your home directory, such as /home/samiux. You can install it now.

cd ..

For 64-bit system :
sudo dpkg -i hiawatha_6.17.1_amd64.deb

For 32-bit system :
sudo dpkg -i hiawatha_6.17.1_i386.deb

Step 3 - Configure PHP5

Edit the php.ini.

sudo nano /etc/php5/cgi/php.ini

Make change as is.

display_errors = Off
log_errors = On
allow_url_fopen = Off
safe_mode = On
expose_php = Off
enable_dl = Off
disable_functions = system, show_source, symlink, exec, dl, shell_exec, passthru, phpinfo, escapeshellarg, escapeshellcmd

*Note : some PHP application may requires safe_mode = Off.

Edit Hiawatha's php-fcgi.conf.

sudo nano /etc/hiawatha/php-fcgi.conf

Uncomment the following line.
Server = /usr/bin/php5-cgi ; 127.0.0.1:2005 ; www-data

Activate php-fcgi.

sudo php-fcgi -c /etc/hiawatha/php-fcgi.conf

If you make any change on php-fcgi.conf, make sure to restart it by following commands.

sudo php-fcgi -k -c /etc/hiawatha/php-fcgi.conf
sudo php-fcgi -c /etc/hiawatha/php-fcgi.conf

Step 4 - Configure Hiawatha

Edit the file hiawatha.conf.

sudo nano /etc/hiawatha/hiawatha.conf

Uncomment ServerId at GENERAL SETTINGS.
ServerId = www-data

Add the following line at the GENERAL SETTINGS. Apache compatible log file format.
LogFormat = extended

Uncomment the following entries at BINDING SETTINGS.
Binding {
   Port = 80
   MaxKeepAlive = 30
   TimeForRequest = 3,20
}

Uncomment all the entries at BANNING SETTINGS.
BanOnGarbage = 300
BanOnMaxPerIP = 60
BanOnMaxReqSize = 300
KickOnBan = yes
RebanDuringBan = yes
BanOnSQLi = 0
BanOnFlooding = 10/1:15
BanlistMask = allow 192.168.0.0/24

*Note : Make change to the Banlistmask in order to meet your network requirement.

Uncomment php5-cgi and CGIextension lines.
#CGIhandler = /usr/bin/perl:pl
CGIhandler = /usr/bin/php5-cgi:php
#CGIhandler = /usr/bin/python:py
#CGIhandler = /usr/bin/ruby:rb
#CGIhandler = /usr/bin/ssi-cgi:shtml
CGIextension = cgi

Uncomment all the entries of FastCGIserver and rename ConnectTo to 127.0.0.1:2005.

FastCGIserver {
   FastCGIid = PHP5
   ConnectTo = 127.0.0.1:2005
   Extension = php, php5
   SessionTimeout = 30
}

Optional - Create the following lines under URL TOOLKIT.

UrlToolkit {
   ToolkitID = CMS_common
   RequestURI isfile Return
   RequestURI exists Return
   Match ^/(favicon.ico|robots.txt|sitemap.xml)$ Return
   Match .*\?(.*) Rewrite /index.php?$1
   Match .* Rewrite /index.php
}

*Note : UrlToolkit is similar to Apache's mod_rewrite.

Create a VirtualHost for your site.

VirtualHost {
   Hostname = samiux.blogspot.com
   Alias = /php_my_admin:/usr/share/phpmyadmin
   WebsiteRoot = /var/www/blog
   StartFile = index.php
   AccessLogfile = /var/log/hiawatha/blog/access.log
   ErrorLogfile = /var/log/hiawatha/blog/error.log
   TimeForCGI = 5
   UseFastCGI = PHP5
   UseToolkit = CMS_common
   ExecuteCGI = yes
   PreventCMDi = yes
   PreventCSRF = yes
   PreventSQLi = yes
   PreventXSS = yes
   DenyBot = Googlebot:/
   DenyBot = twiceler:/
   DenyBot = MSNBot:/
   DenyBot = yahoo:/
   DenyBot = BaiDuSpider:/
   DenyBot = Ask:/
   DenyBot = Yahoo! Slurp:/
   DenyBot = Sogou web spider:/
   DenyBot = Sogou-Test-Spider:/
   DenyBot = Baiduspider+:/
   DenyBot = Yandex:/
   DenyBot = UniversalFeedParser:/
   DenyBot = Mediapartners-Google:/
   DenyBot = Sosospider+:/
}

*Note : Some CMS will not well when PreventCMDi = yes. DenyBot entries are optional. If you do not want spiders and bots to crawl your site, you should enable it. Those entries are examples only. UseToolKit is also optional.

Make sure /var/log/hiawatha/blog exists (example) and its ownership is www-data.

If not, make it as is.
sudo chown -R www-data:www-data /var/log/hiawatha/blog

Restart Hiawatha.
sudo /etc/init.d/hiawatha restart

Now, make sure the ownership of access.log and error.log are www-data. If not, make them as is.

sudo chown www-data:www-data /var/log/hiawatha/blog/*

Step 5 - Configure Apparmor (to make Hiawatha more safety)

Create Apparmor profile for Hiawatha.
sudo aa-genprof hiawatha

Edit the profile usr.sbin.hiawatha.
sudo nano /etc/apparmor.d/usr.sbin.hiawatha

Make the entries look like this.

# Last Modified: Tue Sep 1 10:28:15 2009
#include

/usr/sbin/hiawatha {
   #include

   capability chown,
   capability dac_override,

   /var/log/hiawatha/blog/** a,
   /var/run/hiawatha.pid w,
   /var/www/ r,
   /var/www/** rw,
}

Make the profile in enforce mode (active).
sudo aa-enforce hiawatha

If you have change some settings, you should reload the profile.
sudo apparmor_parser -r < /etc/apparmor.d/usr.sbin.hiawatha

If you want to disable this profile.
sudo ln -s /etc/apparmor.d/usr.sbin.hiawatha /etc/apparmor.d/disable/
sudo apparmor_parser -R < /etc/apparmor.d/usr.sbin.hiawatha

If you want to re-enable this profile after it has been disabled.
sudo rm /etc/apparmor.d/disable/usr.sbin.hiawatha

HOWTO : Hiawatha 6.16 web server on Ubuntu 9.04 Server

Hiawatha is a web server which is developed by Hugo Leisink who is in a great interest in IT security. It is designed with security in mind. It comes with Cross-site Scripting (XSS) prevention, Cross-site Request Forgery (CSRF) prevention, DoS/flooding protection, and SQL injection prevention.

It works with PHP and MySQL. Therefore, the LAMP (Linux, Apache, MySQL and PHP) should be renamed to LHMP (Linux, Hiawatha, MySQL and PHP).

Step 0 :

Install Ubuntu 9.04 Server and OpenSSH as usual. Make sure to perform the following.

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

Step 1 :

Download Hiawatha, the current version at this writing is 6.16, at http://www.hiawatha-webserver.org/download.

sudo wget http://www.hiawatha-webserver.org/files/hiawatha-6.16.tar.gz
tar -xzvf hiawatha-6.16.tar.gz
cd hiawatha-6.16

Configure and compile the Hiawatha.

sudo apt-get install build-essentail libc6-dev libssl-dev dpkg-dev debhelper fakeroot libxml2-dev libxslt1-dev

sudo ./configure
sudo make deb

The deb package will be created at /home/samiux. You can install it by :

sudo dpkg -i hiawatha_6.16_amd64.deb

or

sudo dpkg -i hiawatha_6.16_i386.deb

Step 2 :

Install mysql and php5.

sudo apt-get install mysql-server mysql-client php5-cgi php5 php5-cli php5-mysql php5-curl php5-gd php5-idn php-pear php5-imagick php5-imap php5-mcrypt php5-memcache php5-mhash php5-ming php5-ps php5-pspell php5-recode php5-snmp php5-sqlite php5-tidy php5-xmlrpc php5-xsl

Enter the password for the MySQL and write it down for further usage.

Step 3 :

sudo nano /etc/hiawatha/php-fcgi.conf

Uncomment the following line :

Server = /usr/bin/php5-cgi ; 127.0.0.1:2005 ; www-data

Activate php-fcgi.

sudo php-fcgi -c /etc/hiawatha/php-fcgi.conf

Kill it with -k, such as :

sudo php-fcgi -k -c /etc/hiawatha/php-fcgi.conf

*Make sure you have been activated php-fcgi; otherwise, php5 cannot be run.

Step 4 :

sudo nano /etc/hiawatha/hiawatha.conf

Uncomment ServerId at GENERAL SETTINGS.

ServerId = www-data

HOWTO : Godaddy.com's Relay Mail Server with Postfix on Ubuntu 9.04 Server

Your Internet Services Provider (ISP) may block SMTP port (Port 25) if you are not using a business plan (like in Hong Kong). However, you can still send email with reverse lookup of your domain name when your domain registrar is Godaddy.com.

Step 1 :

Create and enable your free email account at Godaddy.com when you have a domain name there. Set the password accordingly. Your username of the account may be look like this : yourname@yourdomain.

Incoming Mail Server Type : POP3
Incoming Mail Server : pop.secureserver.net
Incoming Mail Server Port : 110

Outgoing Mail Server : smtpout.secureserver.net
Outgoing Mail Server Port : 25, 80, 587 or 3535

Step 2 :

Create a file namely "sasl_passwd".

sudo nano /etc/postfix/sasl/sasl_passwd

Add the following line.

smtpout.secureserver.net username:password

Step 2a :

Save and quit. Issue the following commands.

chown root:root /etc/postfix/sasl/sasl_passwd
chmod 600 /etc/postfix/sasl/sasl_passwd
postmap /etc/postfix/sasl/sasl_passwd

Step 3 :

Go to your mail server (Postfix).

sudo nano /etc/postfix/main.cf

Edit or/and add the following lines.

relayhost = [smtpout.secureserver.net]
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl/sasl_passwd
smtp_sasl_security_options = noanonymous
mynetworks = 192.168.0.0/24, 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128

*If your network is 192.168.0.0/24, otherwise; change it accordingly.

Step 4 :

Restart the Postfix to make it work.

sudo /etc/init.d/postfix restart

Step 5 :

Now, you can send email with reverse lookup via Godaddy.com's relay mail server. Your email will not be blocked or redirected to "Junk Mail" folder by Gmail, Yahoo Mail or others.

Be keep in mind that you have 250 quota every day. Or, you are required to purchase more quota.

Point to your email server on other servers that will send email.

HOWTO : Performance tuning for PostgreSQL on Ubuntu 9.04 Server

Step 1 :

Edit postgresql.conf.

sudo nano /etc/postgresql/8.3/main/postgresql.conf

Step 2 :

The performance tuning setting is as the following :

(1) shared_buffers

Recommended : 0.25 * Available Memory

(2) work_mem

Recommended : Available Memory / max_connections
(If your queries tend to be more complicated, then divide that by 2. If you typically run very close to max_connections connections, then consider dividing by 2 again. If that gives you a number that isn't at least 16MB, buy more memory.)

(3) maintenance_work_mem

Recommended : Available Memory / 8

(4) wal_buffers

Recommended : 8MB

(5) checkpoint_segments

Recommended : 16 to 128

(6) effective_cache_size

Recommended : Available Memory * 0.75

(7) cpu_tuple_cost

Recommended : 0.0030

(8) cpu_index_tuple_cost

Recommended : 0.0010

(9) cpu_operator_cost

Recommended : 0.0005

(10) fsync

Recommended : off

Warning : If “fsync” is set to “off”, you may encounter data loss when the power failure unless you have a battery backup unit at your hardware RAID card.

(11) max_connection

Recommended : 140% (100 clients average means 140 max connections)

(12) checkpoint_timeout

Recommended : 1h

Step 3 :

Restart PostgreSQL server.

sudo /etc/init.d/postgresql-8.3 restart

Step 4 :

If it produces error message and cannot restart, change the setting for "kernel.shmmax" on sysctl.conf as suggested.

Edit the sysctl.conf as suggested.

HOWTO : Sockso 1.1.8 (Music Server) on Ubuntu 9.04 Server

Sockso is a cross platform music server and requires no installation. She runs on a standalone personal computer or on a server. For running on personal computer with GUI, please refer to her official site.

The client computer requires no mp3 player to play the music but needs a Flash player.

The advantage of Sockso is that you can listen to your mp3 files at anytime and anywhere under the condition that fast internet connection is available. The disadvantage is that you should have at least IEEE 802.11g (54M) Wifi connection for smooth operation.

Sockso requires Sun Java only and it is requires no Apache or other web server to run.

Step 1 :

Sockso requires Sun Java to work. You should install the following packages.

sudo apt-get install sun-java6-bin sun-java6-fonts sun-java6-jre unzip

Step 2 :

Download the latest version of Sockso. The current version is 1.1.8 at the time of this writing.

wget http://sockso.googlecode.com/files/sockso-1.1.8.zip

unzip sockso-1.1.8.zip

sudo mkdir /usr/share/sockso

sudo cp -R /home/samiux/sockso-1.1.8/* /usr/share/sockso/*

sudo mkdir /var/sockso
sudo chmod -R 0755 /var/sockso

Step 3 :

Run the Sockso at command prompt.

sudo sh /usr/share/sockso/linux.sh --nogui --datadir /var/sockso

If you have some mp3 at /home/samiux/music and /home/mary/mp3, just runs the following command to make the music collection.

#SockSo#>coladd /home/samiux/music
#SockSo#>coladd /home/mary/mp3

If you want to list all collections, use the following command.

collist

If you want to delete one of the collections, use the following command.

coldel

Add a user to the Sockso.

#SockSo#>useradd samiux samiux@gmail.com

To exit the #SockSo#> command prompt.

exit

Step 4 :

Copy the init.d script to /etc/init.d/

sudo cp /usr/share/sockso/scripts/init.d/sockso /etc/init.d/sockso.pl

Create a sockso script file.

sudo nano /etc/init.d/sockso

-------- CUT HERE ---------
#!/bin/bash

perl /etc/init.d/sockso.pl $1

exit 0
-------- CUT HERE ---------

Edit the sockso.pl as the following.

sudo nano /etc/init.d/sockso.pl

use constant SOCKSO_DIR => "/usr/share/sockso/";

system( 'sh linux.sh --nogui --datadir /var/sockso > /dev/null 2>&1 &' );

Step 5 :

Now, you can start the sockso with the following command.

sudo chmod +x /etc/init.d/sockso
sudo chmod +x /etc/init.d/sockso.pl

sudo /etc/init.d/sockso start

You can also stop the sockso with the following command.

sudo /etc/init.d/sockso stop

Listen to the music with your browser.

http://192.168.0.100:4444

Step 6 :

Make the script to be ran automatically after reboot.

sudo update-rc.d sockso defaults

Remarks : Make sure you have stopped the Sockso before reboot or shutdown; otherwise, the mp3 databases would be corrupted. If so, you should delete everything inside /var/sockso and redo the Step 3.


Remarks : Don't broadcast copyrighted musics or songs. Or, you may be in lawsuit.

That's all. See you!

HOWTO : WebDAV on Ubuntu 9.04 Server

WebDAV is a file manager that running on web server. You can access it like on your desktop. Easy and enjoyable.

Install Ubuntu 9.04 server as usual and select LAMP and OpenSSH when asked for choice. You can also install vsFTPd if you want to but it is optional.

Step 1 :

sudo a2enmod dav_fs
sudo a2enmod dav
sudo a2enmod dav_lock

sudo a2dissite default


sudo /etc/init.d/apache2 restart


Step 2 :

To create a virtual host for the WebDAV.

sudo mkdir -p /var/www/webdav
chown www-data /var/www/webdav

sudo cp /etc/apache2/sites-available/default /etc/apache2/sites-available/webdav

sudo nano /etc/apache2/sites-available/webdav

Make the a portion of the file as the following :


....
DocumentRoot /var/www/webdav

   Options Indexes FollowSymLinks MultiViews
   AllowOverride None
   Order allow,deny
   allow from all


   DAV On
   AuthType Basic
   AuthName "webdav"
   AuthUserFile /var/www/.passwd.dav
   Require valid-user
   DavMinTimeout 600
   
      Require valid-user
   

....


Step 3 :

sudo htpasswd -c /var/www/.passwd.dav samiux

chown root:www-data /var/www/.passwd.dav
chmod 640 /var/www/.passwd.dav

suod chmod -R 0777 /var/www/webdav
sudo chown www-data:www-data /var/www/webdav

sudo /etc/init.d/apache2 restart

Step 4 :

To test if WebDAV works or not.

sudo apt-get install cadaver

sudo cadaver http://localhost/

If you got “dav:/” prompt, enter “quit” to quit. Otherwises, fix the problem.

Step 5 (Windows only) :

Download NetDrive at http://www.netdrive.net/ and set it accordingly. The port should be 80.

Now you can access your WebDAV server from Windows.

Step 6 (Ubuntu only) :

Go to “Place” > “Connect to Server“. Select “WebDAV (HTTP)“. Enter the IP of your WebDAV server and then press “Connect“. Submit the username and password. An icon will be displayed on your desktop. Double click it and go.

Now you can access your WebDAV server from Ubuntu.

OpenOffice

If you open the OpenOffice files on the WebDAV by clicking, you can only open it in read only mode. However, there is method to overcome this problem. You open OpenOffice Write (for example), click the “Open file” and at the “Name of file” enter the following :

vnd.sun.star.webdav://192.168.0.100/openoffice_readonly_on_webdav.odt

Now you can edit and save it on WebDAV.

Limitation of WebDAV

You can paste a file onto WebDAV directly but there is a file size limitation, that is, the file should be less than 1GB. If you want to paste a file larger than 1GB, I suggest to use FTP instead.

Make sure to change the ownership of the files that you have uploaded by FTP.

sudo chown -R www-data:www-data /var/www/webdav

That’s all!
