HOWTO: Configure SELinux for Recital Web


SE Linux is a feature of the Linux kernel that provides mandatory access control. This policy based access control system grants far greater control over the resources on a machine than standard Linux access controls such as permissions.

Many modern Linux distributions are shipping with SELinux enabled by default, Fedora 14 and Rhel 6 both install with it enabled.

When you run Recital Web on a SELinux enabled machine and navigate to the default.rsp page you will see something similar to the screen shot below.

1
If you launch the SELinux troubleshooter you will see the following problem.

SELinux is blocking the apache server from accessing the Recital server running on port 8001.

2
To manage you SELinux policy you must have the policycoreutils package group installed. The policycoreutils contains the policy core utilities that are required for basic operation of a SELinux system.

If you wish to use a GUI tool, you must install the policycoreutils-gui package.

At the command prompt execute the following:

As root

$ yum install policycoreutils

$ semanage port -a -t http_port_t -p tcp 8001

$ service recital restart

$ service httpd restart 
 

We use the semanage command here to allow the http server access to port 8001. Once you have completed the steps detailed above you can go and navigate back to the default.rsp page in your borwser, where you will find the permission denied message is now replaced by the default.rsp page.

SELinux does a great job of restricting services and daemons so rather than simply disabling it, why not work with it!

When it comes to security, every little bit helps...

Template additional styles

In order to get the video you have to use code like this:


<a class="gk_video_frame" href="http://www.vimeo.com/16274294" rel="mediabox[720 410]">
    <img src="/images/stories/demo/demo_video_1.png" border="0" alt="Video 1" />
    <span class="gk_vframe">Frame</span> 
    <span class="gk_voverlay">Overlay</span> 
    Watch the video 
</a>

As a href attribute you set the video address. In the rel attribute you can specify the video size. Image element is the thumbnail in the frame.

You can also create a blocks with icons. The structure is always similar - you have to change only second class near gk_block:


<div class="gk_block tablet">
<h3><a href="#">Mobile Ready</a></h3>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Cras quis erat elit. Donec pretium condimentum</p>
</div>

Available blocks styles with classes:

HOWTO: Automate ssh logins to remote machines

Here is a simple shell script to copy your ssh authorization key to a remote machine so that you can run ssh and scp without having to repeatedly login.

#!/bin/sh
# save in file ssh_copykeyto.sh then chmod +x ssh_copykeyto.sh
KEY="$HOME/.ssh/id_rsa.pub"
if [ ! -f ~/.ssh/id_rsa.pub ];then
    echo "private key not found at $KEY"
    echo "create it with "ssh-keygen -t rsa" before running this script
    exit
fi
if [ -z $1 ];then
    echo "Bad args: specify user@host as the first argument to this script"
    exit
fi
echo "Copying ssh authorization key to $1... "
KEYCODE=`cat $KEY`
ssh -q $1 "mkdir ~/.ssh 2>/dev/null; chmod 700 ~/.ssh; echo "$KEYCODE" >> ~/.ssh/authorized_keys; \
chmod 644 ~/.ssh/authorized_keys"
echo "done!"

Using the Recital PIPETOSTR() function

Recital 10 introduced the PIPETOSTR() function. This function operates in a similar fashion to the FILETOSTR() function but it can be used to capture the output from externally executed operating system commands. e.g. 
// determine how many Recital users are on the system
nusers = pipetostr("ps -ef | grep db.exe | wc -l")

Building C Extension Libraries

In this article Barry Mavin, CEO and Chief Software Architect for Recital details how to Build C Extension Libraries to use with Recital.

Overview

It is possible to extend the functionaliy of Recital products using "Extension libraries" that can be written in C. These extension libraries, written using the Recital/SDK API, are dynamically loadable from all Recital 9 products. This includes:

  • Recital
  • Recital Server
  • Recital Web

Building C Extension Libraries

You can create C wrappers for virtually any native operating system function and access these from the Recital 4GL. Unlike traditional APIs which only handle the development of C functions that are callable from the 4GL, the Recital/SDK allows you to build Classes that are accessible from all Recital products. e.g. You could create a GUI framework for Linux that handles VFP system classes!

To deploy your C Extension Libraries, copy them to the following location:

Windows:

\Program Files\Recital\extensions

Linux/Unix:

/opt/recital/extensions

Please see the Recital/SDK API Reference documentation for further details.

Sample code

Listed below is the complete example of a C Extension Library.:

Clustering VMware server with Heartbeat and DRBD on linux

This website runs in a  virtual machine under vmware server. It is clustered between two servers using heartbeat and DRBD.
 
When VMware server starts up a virtual machine it generates a uuid (unique id) based on the machine it is running on and stores this in the .vmx file.
 
When heartbeat switches from slave to master, it will start VMware server (which is setup as a resource in the haresources file).
 
Virtual machines that you want started automatically when you start VMware server will not start because the uuid changes between the master and backup systems. To get around this problem always do the following:
  • edit the .vmx file and add the following line

    uuid.action = "keep"
If this is not done then everytime you try to run the virtual machine on the backup system in your cluster, VMware server will complain that the virtual machine has been copied or moved and it will not start it.
  • set the virtual machine to power off when vmware is stopped. Do not set this to "suspend" or it will not restart on the backup machine.
This will allow the virtual machine to start properly on the backup machine.

HOWTO: Configure Samba for Recital and FoxPro

Recital's version of Samba allows application data to be shared and locked correctly across these systems, allowing a truly integrated heterogeneous data environment. For example Recital applications running on a UNIX/Linux server can read and update FoxPro databases residing on a Microsoft Windows NT server through the use of Samba.
You can view the modified changes by downloading the following files and patching these into your current Samba installation.
open.c (file opening and share modes)
version.h (versioning information)
The variable CPPFLAGS in the file Makefile will require the define -DRECITAL added to it.
In order to make the locking compatible between UNIX/Linux and Windows the following environment variable must be placed in the profile.db for Unix/Linux Developer and in profile.uas for the Universal Application Server:
DB_SAMBA=YES ;export DB_SAMBA 
The following settings need to be added to the smb.conf file to ensure that file names are always converted to lower case:
preserve case = no 
default case = lower 
mangle case = yes 
The following settings need to be added to the smb.conf file for locking to operate correctly:
oplocks = False 
share modes = no

Centos 5.3 Released!


I am pleased to finally report that the Centos release of Redhats 5.3 has been built and is available for download from http://www.centos.org/

The highlights of this release can be found at the following URL: http://www.redhat.com

The main areas of interest in my opinion excluding critical secirty fixes are:

  • Updated hardwaresupport support for the new Intel Core i7 (Nehalem) chips
  • Beefed up virtualiseation support increasing CPU and Ram limits of Virtual machines.
  • Inclusion of the fully open sourced OpenJDK. This makes Red Hat Enterprise Linux 5.3 the first enterprise-ready solution with a fully open source Java stack when combined with JBoss Enterprise Application Platform.


For those who already have Centos 5.2 installed you can simply receive the update via Yum.

Before you do the following, check that  you do not have 3rd party repo's and the Centos-testing repo enabled.

You can display the currently enabled repo's using the following command.

$ yum repolist



Then as root at the prompt type:

$ yum update
