September 15th, 2010 by admin

FreeBSD comes by default with sendmail email server installed, but its not secure and scalable enough.

Building secure Email Server from scratch is a huge task, because it need many component to be installed and configured.

My objective was to build a secure, fast, reliable email server, very less and optimized system resource, using SSL, have a web interface for administration, web interface for clients, can be accessed by email clients application like Microsoft outlook and Microsoft outlook express, also my email server should be protected against spam and virus scan capabilities.

Secure Email Server component include:

  • Install and configure Apache  server.
  • Install and configure PHP.
  • Install and configure MySql server.
  • Create SSL/TLS certificate using openssl.
  • Install and configure Dovecot POP3/IMAP server.
  • Install and configure PostFix the alternative to Sendmail.
  • Install and configure PostFixAdmin.
  • Install and configure squirrelmail.
  • Install and configure SpamAssassin.

FreeBSD Text based browser with Javascript support

August 7th, 2010 by admin

Sometimes I need to do some testing or just a quick browsing for a web site while working on FreeBSD server without any graphical interface, its only text mode.

one solution is to use links, to install links text browser just follow this steps:

  1. #cd /usr/ports/www/links1
  2. #make install clean

to start browsing just type

#links url

ex:

#links google.com

links can work with mouse also.

to get  links text browser menu press Esc and the links menu will appear which contain many options like file, view, download, setup, and help, to exit links text browser press q.

to get more inforamtion about links text based www web browser you can use:

  • #man links

links web site

Another solution for text browser is elinks which looks more recent with better functionality than links.

to setup elinks use:

  • #cd /usr/ports/www/elinks
  • #make install clean
  • configuration screen will appear then select the options you need.
  • to run elinks simply type  :
  • #elinks google.com

elinks website

unfortunately both links and elinks text browser is not supporting javascript.

so still looking for some thing else.
