Installing WebMin to manage Linux in Ubuntu 7.10

Steps Needed:

1) Install these packages

sudo apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl libmd5-perl

2) Download the latest webmin using the following command

wget http://prdownloads.sourceforge.net/webadmin/webmin_1.370_all.deb

Please notice that if you are behind a proxy you must first set an environment variable to contain the proxy address for wget to use it. Do:
If you are using Bourne-style shell (sh, bash, ksh) type the following command: http_proxy=http://bcproxy.ac.il:8080/ ; export http_proxy. For C-shell (csh, tcsh) type setenv http_proxy=http://bcproxy.ac.il:8080/. You may wish to add apropriate command into your .profile (Bourne-style shell users) or .login (C-shell users) files.

3) Install the package using the following command

sudo dpkg -i webmin_1.370_all.deb

4) WebMin is now available at:

https://your-server-ip:10000/

5) To enable SMART hdd monitoring in WebMin you must install smartmon tools:

sudo apt-get install smartmontools

Installing VmWare Server on UBUNTU 7.10 Server

First, this how-to applies when you are using a kernel that is latest than the one needed by the VMWARE release you are using.

Here is how to do it:

1) Download VMware Server source from the VMware website.
You can use lynx:

sudo apt-get install lynx

2) Download this installer patch:
http://knihovny.cvut.cz/ftp/pub/vmware/vmware-any-any-update113.tar.gz

3) Extract all the archives to a location on your system by using:

tar -zxvf VMware-server*
tar -zxvf vmware*

4) Ensure that you have build-essential installed in order to compile these sources:

sudo aptitude install build-essential

4) Also ensure that you have the proper headers for your running kernel:

sudo apt-get install linux-headers-$(uname -r)


This is important because if you don't then all that is needed to build and compile vmware will not be available.

5) Install the xinetd server:

sudo aptitude install xinetd

6) Install the xorg-dev tools because of shared library that vmware-server uses to validate keys.

sudo apt-get install xorg-dev
(sudo apt-get install libx11-dev)
(sudo apt-get install libx11-6)

7) Install wget, a command line http deamon because you will need it later

8) Run sudo ./vmware-install.pl located within the vmware-server-* unpacked archive.

sudo ./vmware-install.pl

8) # Select all the default options *EXCEPT* do not compile the modules at this point. (Do you want this program to try to build the vmmon module for your system? NO)

9) Run sudo ./runme.pl located within the vmware-any* archive. This will install the PATCH and resume step 8 where you said no.

10) Select the default options and this time answer YES to compile the proper modules.

By default your virtual machines will be installed at [/var/lib/vmware/Virtual Machines]


11) Execute the VMware Management Interface (MUI) installer:

do:
apt-get install libxi6

I have found that under cirmcumstances i don't fully understand it will not install without this.

tar xzf VMware-mui-1.0.4-56528.tar.gz
cd vmware-mui-distrib
sudo ./vmware-install.pl

This will install the vmware web services wich will responde as https on port 8333.

10) Download this file: http://www.iki.fi/kuparine/comp/ubuntu/en/httpd.vmware.diff
You can do it by using:

cd /tmp
wget http://www.iki.fi/kuparine/comp/ubuntu/en/httpd.vmware.diff
cd /
patch -b -p0 < /tmp/httpd.vmware.diff

The last command will patch the vmware apache install so that it will work properly.

11) Run vmware-server using the command vmware or via your Applications Menu.

12) Do "cd /etc/init.d" and "sudo ./httpd.vmware start" to start MUI

This how-to was mostly (but not only) based on this excelent how to:

Ubuntu Notes

Ubuntu does not use yum. Go figure, or better yet, use apt-get.

Critical needs for ubuntu:

1. Installing SSH server for remote administration service.

---> sudo apt-get install ssh

This will istall a ssh server in the default dir allowing for remote admin over and encrypted session.

2.Installing the SUN Java Virtual Machine.

At first you will see that the JavaVM you have is an open-source one. NOT GOOD. check it like this:


user@ubuntusrv:~$ java -version
The program 'java' can be found in the following packages:
* j2re1.4
* gij-4.1
* kaffe
* jamvm
* java-gcj-compat
* cacao
* sablevm



To install the java virtual machine you can download the package via apt-get (instead of other cases in wich you have to do it via dowloading the package from Sun's web site.

---> sudo apt-get install sun-java6-bin

After you install you should get something like this:

suer@ubuntusrv:~$ java -version
java version "1.6.0"
Java(TM) SE Runtime Environment (build 1.6.0-b105)
Java HotSpot(TM) Client VM (build 1.6.0-b105, mixed mode, sharing)

JAVA is installed!

3. Now we need to install Lynx. Lynx is a great text based browser that will enable you to access the internet and download anything you might need as it will be the case.

sudo apt-get install lynx
