Usermin:

Installation
Method-1:
Step by step installation (Complicated and usually I do not follow) guide available on the followin URL-

http://www.linuxjunkies.org/adminstration%20Howto/webminguide/x804.htm

Method-2: (My Way):
Installation within Webmin.

1. Under “Un-used Modules” from the left frame
2. “Usermin Configuration” hyper link
3. “Install usermin RPM package“

Configuration:

Actually there’s nothing much to configure on usermin other than setting up webmail and few links not to show your clients!

After installation- it is very hard to locate Usermin within Webmin! but you can find them 🙂

1. You can find usermin by typing “usermin” from the webmin search box
2. You can directly access the Usermin module by http://IP:10000/usermin

But do no access to http://IP:20000 the usual usermin client panel- you can not configure usermin module from here. You can configure once you are logged in to webmin framework.

You can customize your usermin whatever fits your need. I did the following from my setups-

1. Usermin Module coniguration > Read Mail
   Sendmail mail file location = /home/mail
   Mail storage format for Inbox = Sendmail style single file (mbox)
   Mail subdirectory style= mail/username
2. Available Modules (see the scrren shot)

That’s it! Seeya in the next chapter 😐

Webmin

Well, webmin is a composite word “Web Based Admin”- literally speaking, those who scares the terminal configurations, they can try working with this Webmin.

Webmin is something that I use for-

• Configuring and Administering SQUID Proxy server
• Configuring & Administering NAT Routing or even you can setup a soft router instead of a costly Router devices
• Configuring & Administering the LAMP servers
• Create different admin level for different tasks
• Configuring and Administering HSP system

Basically, to me Webmin is kind of a “Framework” system- like an umbrella that allows other modules, applications/APIs to be incorporated like their own Usermin or Virtualmin. Anyone can work on this project and can write modules CGI applicaiton. It’s entirely written in Perl (shell coding).

There are plenty of potentials in Webmin- I also did used this for Asterisk (IP-PBX) and Jabber (XMPP Messenger server).

Here’s what they’d like to say on their site-

Webmin is a web-based interface for system administration for Unix. Using any browser that supports tables and forms (and Java for the File Manager module), you can setup user accounts, Apache, DNS, file sharing and so on.

Webmin consists of a simple web server, and a number of CGI programs which directly update system files like /etc/inetd.conf and /etc/passwd. The web server and all CGI programs are written in Perl version 5, and use no non-standard Perl modules.

So, this is enough what webmin is, visit them- http://www.webmin.com

Yes, here’s teh mammoth task I’ve decided to write down with automate task with- Fedora Core-5, Webmin, usermin and Vitualmin. this is part-1, I don’t know how many parts will there be in documenting up these tasks.

Well, first let me explain why all these…

Locating the business model:

Probably this is the biggest reason of why to look for such options. Well, I’m quite familiar with PLESK on Windows 2003 platform. I also have a seperate plan on documenting PLESK installation and maintenance on Windows Hosting Automation.

Yup, the words already mentioned- Hosting Automaiton. We actually we going to materialize the Hosting business quite lately, after the B/w cost minimizaiton and few potentials to get better B/w. As a part of this, I did set up 3 Hosting Control Automation System as HSP (Hosting Service Provider) on windows 2003 server- 2 located in Dhaka and 1 located in London.

All those platforms are running just superb! The biggest credit was the licensing issue… once received those, it took me no time to set up and running.

So, there goes all those 3 set ups… now what about the little penguin- are we all neglecting or forgetting this “Penguin”- LINUX and its hosting automation?

Of course not! But C-Panel is costly!!!!

Why should we bother when the perfect OS is entirely free but there is not Hosting Automation Applicaiton available other than C-Panel? Actually, C-Panel is popular, widely used by mass of HSP and the biggest point is plenty of API tools & goodies are developed widely!

Anyway, FREE HSP is the cheapest, and if we can ignore the last point I just mentioned- we can plan to set up Virtualmin on Webmin framework!

Chosing the OS:

Well, here’s the most important aspect in choosing the right OS. And again anyone have any liberty in putting up any Linux Distros- Redhat 9 or Enterprise 5 or Fedora 5 & onwards or CentOS 4 & onwards… most likely all have the same output- but if you ask me for commercial executions- I’ll definitely consider Redhat Enterprise or CentOS- the reason is simple- Slow paced but most Stable developments rather than FC packages (it’s the most non-balanced platform).

Then why the heck did I plan to work on FC-5 where FC-9 is released? The answer is quite simple- limited resource on the server. I picked to work on a Pentium-3 machine having only 256 MB RAM and I with this I can’t afford more than FC-5 installation! 🙂

Summary:

Well enough of intros. Let me explain the step by step prerequisites to set up a Hosting Control Panel (HSP)-

• Server OS- Fedora Core 5
  Software package- Apache, MySQL, Webalizer, ProFTPD (installation distribution does not include this, you have to use “YUM INSTALL PROFTPD” on the terminal once FC installation is done), Postfix, Dovecot- POP3 & IMAP, BIND
• Download and install the latest version of webmin (http://www.webmin.com) when OS is done. Usually I prefer the RPM packages, if you install FC on GUI interface, you can set it up like any other windows setup application by double clicking the RPM file. Normally, webmin is installed in http://IP:10000 or https://IP:10000
• Log in to Webmin using the username as “root” and your root password
