XRDP in OpenSuse 11.0/11.2/11.3

September 28, 2012 by Rumi

This tutorial is for advanced users who prefer to skate all the detail that attaches to a "new user" Tutorial. The details (wherein lies the devil) are here: Windows Linux RDP Remote Desktop Connections using openSUSE as Client or Server (terminal server) FWIW there's also an 11.1 version there.

Tested in openSUSE 11.2 KDE & Gnome 32 & 64 bit. In 11.3 I tested KDE & Gnome 64 bit and KDE 32 bit.
There are 4 simple steps

Step 1: Download and install the software

This link contains the RPMs. They work for openSUSE 11.2 and 11.3. Drill down to either the 32 bit i586 RPMs or the 64 bit x86_64 RPMs and download one each of these RPMs: xorg-x11-server-dmx, xorg-x11-server-rdp and xrdp. There are dependency issues to cater for so put the three in a folder anywhere and add that folder as a "local directory" in Yast's –> Software –> Repositories module. Install all three. That's for the server. If you need the client, you also install the RPM for rdesktop from your standard media.

Step 2: Open the firewall

GoTo Yast's firewall module –> Allowed Services –> Select –> Remote Desktop Protocol –> Add.

Step 3: Start the service

If you want the service on permanently goto Yast –> System –> Services / Runlevels –> xrdp –> Enable
If you want the service occasionslly, enable it with "sudo /usr/sbin/rcxrdp start" and turn it off with "sudo /usr/sbin/rcxrdp stop".

Step 4: Port Forwarding

Go to your router by http:// and forward port TCP 3389 to the server IP address.

Paparazzi pops Princess Kate’s puppies

September 15, 2012 by Rumi

Well, this news interests me for many reasons, and I think this really who they are!!!

While enjoying a romantic getaway in France with William, the future Queen of England Kate Middleton decided to get her knockers out, only to be snapped by the awaiting paparazzi.

The Duke and Duchess of Cambridge (Kate and William to you and me) are said to be “saddened” by claims that a French magazine is publishing topless photographs of Kate. Harry, on the other hand, is probably only too delighted – as are we.

Last night the French version of the magazine Closer published pixelated images of Kate on a mock cover, but we've done some digging around and found this:

Installing SL6.3 (64bit) with 'minimal' installation mode
Post installing, fix with the Static IP Address (Public IP and I assume the system is not behind firewall)
Double check with /etc/resolv.conf file parameters

Prerequisites for ZImbra installation

Let's firsy update-

yum update

Let's install some pckages as well

yum – y install sudo sysstat gmp libidn libstdc++ bind bind-chroot bind-libs bind-utils wget php perl nc sqlite

and few more packages-

yum install compat-libstdc++-33 sysstat

If anything missed out you'll know in the next steps, if anything left google it, chances are you'll be able to yum it :), however for this time being the environment is made. Now proceed to download Zimbra.

Make some backend job-

Make sure 'SELINUX' is disabled
The iptables service is stopped
'postfix' service is stopped and disabled at runtime and on boot

Download ZImbra

My downloaded edition was-

http://files2.zimbra.com/downloads/8.0.0_GA/zcs-8.0.0_GA_5434.RHEL6_64.20120907144639.tgz

Install nginx on virtualmin (GPL) server

August 26, 2012 by Rumi

Installing Nginx Support

Switching a system from the Apache webserver (installed by default by Virtualmin to Nginx should only be done if no virtual servers with websites have been created yet. Ideally the change should be done on a freshly installed system, running RHEL 6.0, CentOS 6.0 or Debian 6.0 or later. Virtualmin version 3.89 or above is also required.

The steps to remove Apache and install Nginx are :

Shut down Apache with the command /etc/init.d/httpd stop ; service httpd off (on RHEL or CentOS), or /etc/init.d/apache2 stop ; update-rc.d apache2 remove (on Debian).
Install Nginx with the command yum install nginx (on RHEL or CentOS) or apt-get install nginx (on Debian).
Start the Nginx webserver with the command /etc/init.d/nginx start
Install Virtualmin's Nginx plugin with the command yum install wbm-virtualmin-nginx wbm-virtualmin-nginx-ssl (on RHEL or CentOS) or apt-get install webmin-virtualmin-nginx webmin-virtualmin-nginx-ssl (on Debian).

Using an Aladdin eToken with firefox

August 25, 2012 by Rumi

A very easy method for importing (or removing) keys in your eToken is to add the eToken as a Security Device in Firefox. The procedure for Thunderbird and Mozilla/Seamonkey is nearly identical. To add your eToken as a security device , follow these steps

Start Firefox
(Linux) Go to Edit->Preferences->Advanced->Tab "Encryption"
(Windows) Go to Tools->Options->Advanced->Tab "Encryption"
Click on 'Security Devices'

You should see a screen similar to

Click on 'Load'
In the next screen, enter a (possibly useful) name for this module and Click on 'Browse' to select the appropriate PKCS11 module

Network Configuration on Debian or Ubuntu

August 24, 2012 by Rumi

Setting up an Ethernet Interface

The majority of network setup can be done via the interfaces configuration file at /etc/network/interfaces. Here, you can give your network card an IP address (or use dhcp), set up routing information, configure IP masquerading, set default routes and much more.

Remember to add interfaces that you want brought up at boot time to the 'auto' line.

See man interfaces for more options.

Using DHCP to automatically configure the interface

If you're just using DHCP then all you need is something like:

    auto eth0
    allow-hotplug eth0
    iface eth0 inet dhcp

Install Zimbra on Centos 5 Step by step

August 24, 2012 by Rumi

Zimbra is a suite of tools for Unix/Linux/MacOS systems, which includes a secure mail server, web mail, anti-spam/anti-virus controls, a Web management interface, integrated calendaring, mobile device sync, and more. In many ways, Zimbra is the Unix equivalent to Microsoft Exchange.

In this post, I will be installing Zimbra onto a CentOS virtual machine. The machine will need at least 1024mb of memory to run the default Zimbra services. I was unable to make it run without errors with any less memory.

Things to do after a clean installation of Centos 5.5:

Disable SELinux and
Disable Linux Firewall

The last step is to shutoff some services that will interfere with ZCS.

chkconfig sendmail off
chkconfig ip6tables off
chkconfig iptables off

We need one package before we can continue:

yum install libtool-ltdl

This completes the base installation of CentOS. On the next page we will setup Split DNS which is essential for ZCS. Go ahead and reboot, and fill up that coffee cup.
