Webmin

  1. 1. WEBMIN
  2. 2. Introduction  Webmin is a web-based interface for system administration for Unix. Using any modern web browser, you can setup user accounts, Apache, DNS, file sharing and much more.  Webmin removes the need to manually edit Unix configuration files like /etc/passwd, and lets you manage a system from the console or remotely.  Webmin is largely based on Perl, running as its own process and web server.  It defaults to TCP port 10000 for communicating, and can be configured to use SSL if OpenSSL is installed with additional required Perl Modules. Webmin removes the need to manually edit Unix configuration files like /etc/passwd, and lets you manage a system from the console or remotely.
  3. 3. Features  Web based system configuration tool  Designed for Unix –like environment  Open source  Modular based system
  4. 4. Screenshot Creating a user
  5. 5. Prerequisites  Because it allows logins by any Unix user on your system, Usermin needs some way of checking user passwords. By default, this will be done by just reading the /etc/shadow file directly, but if your system uses NIS this will not work.  On FreeBSD and Solaris, you probably will not need to edit the PAM config file /etc/pam.conf as it is setup to do Unix authentication for unknown services by default.
  6. 6. Prerequisites (contd.)  Webmin takes about 11MB of RAM on a 32 bit system (20-50% more on a 64 bit system).  Webmin idles on around 230mb with Apache/MySQL/FTP etc.. running.
  7. 7. Modules  Usermin :reading mail,setting up SSH,mail forwarding  Virtualmin: domain hosting and website control panel  Cloudmin: managing virtual systems, such as Xen, KVM and OpenVZ instances.
  8. 8. Advantages  Free of cost  Simple UI
  9. 9. Disadvantages  Tricky Configuration  Module configurations are visible  Remote source code access  Usermin cross-site scripting vulnerability  Account lockout attack
