Explore powerful UNIX writer's tools
Long ago, UNIX(R) had a proprietary package called the Writer's Workbench
(WWB). Developers, administrators, and technical writers who used to use this
package in their work deeply miss it -- its powerful capabilities made the UNIX
workstation a preferred environment for document editing and proofreading. Today,
many new implementations of those tools are available for all UNIX systems, and you
can also find open source equivalents of the key WWB tools. Discover these tools and
learn how to use them, building a custom style guide checker in the process.

Tunneling with SSH
Use OpenSource tools, such as Secure Shell (SSH), PuTTY, and Cygwin, to create secure connections to almost any resource you need to access. Current information on SSH tunneling and setup is fragmented and limited to specific applications, or it is written at a system administrator's level. With increasing security needs, the addition of boundary firewalls, and tightening of the number of allowed network ports, users need a method that is simple to configure, easy to operate and, above all, secure to accomplish day-to-day tasks and access the services that they have become accustomed to. This article describes the setup of a simple SSH client connecting to an AIX(R)- or Linux(R)-based SSH server that allows a typical, technically literate individual the ability to set up, configure, and operate a flexible means of tunneling data and services over the SSH service.

Build UNIX software with Eclipse
Become more productive with your own code and others by utilizing Eclipse's syntax highlighting, code completion, and other amenities. Eclipse is an excellent open source IDE and has many helpful features. It runs on any UNIX(R) platform with a Java(TM) Runtime Environment (JRE) (Version 1.4 or newer) and an SWT port, such as Linux(R), Solaris, AIX(R), and HP-UX. It's easy enough to start a new project using Eclipse or to import an existing Eclipse project, but how do you bring existing code into the IDE? And what if you need to get an existing project compiling right away without modifying its existing makefile or configure script -- the most common ways of building UNIX software? Read along for the answer to all of these questions.

Leverage Nagios with plug-ins you write
Learn more about Nagios and find out what new system monitoring possibilities exist
with this software. Nagios is open source monitoring software that scans hosts, services, and
networks for problems. The two main differences between Nagios and other similar
packages are that Nagios reduces all information to "working," "questionable,"
and "failure" statuses; and Nagios supports a particularly rich "ecosystem" of
plug-ins. These features result in effective installations where users are not
overwhelmed with details, but have just the information they need.

Monitoring logs and command output
Monitoring system logs or the status of a command that produces
file or directory output are common tasks for systems
administrators. Two popular open source tools simplify these
activities for modern systems administrators: the multitail and watch
commands. Both are terminal-oriented commands, which means
that they are easily ported to most UNIX or UNIX-like systems
because they do not depend on any specific graphical desktop
environment.

Differentiating UNIX and Linux
Investigate the areas where UNIX(R) and Linux(R) converge in terms of functionality, environment, usability, and also those areas where UNIX and Linux differ. Many refer to Linux as a UNIX-like operating system. It is an open source operating system that has many of the same principles and ideals as UNIX, but it is not a true UNIX operating system like Solaris, AIX(R), HP-UX, and others. This article covers a range of aspects, from the core technical elements, such as kernel and filesystem support, to application tools, availability, and the differences in how to administer them.

Manage blogs on AIX
AIX provides an ideal environment for blogs and for the Web Content
Management System (CMS) tools running those blogs because of its Web and
text-processing power. You get the best of both worlds by combining open source
CMS and AIX for a complete and ready-to-use content management tool with extensive
support from the open source community, along with a secure and reliable server
with high availability, scalability, and enterprise-level support from IBM. This
article introduces some of the best CMS solutions for AIX available from the open
source community, and helps readers understand the important differences among
them. The article also provides a guideline for system architects and developers to help them choose the CMS that best fits their needs.

Samba on AIX
Samba is an open source, free software suite that provides seamless file and
print services between Windows clients and UNIX-like platforms. It can be run on a
UNIX-like platform like AIX, BSD UNIX, Linux, IBM 390 and OpenVMS. Samba uses the TCP/IP protocol that is installed in the host server. When configured, this server software allows the host machine to share files and printers and make them accessible from Windows clients.

Guaranteed porting for a heterogeneous UNIX environment
Use a componentized build system to automatically port Java(TM) projects
with native extensions on heterogeneous UNIX(R) platforms. Today, many large-scale
Java systems running on UNIX-like platforms require third party native library
support, or you have to develop your own native components. Many utilities and
system calls on these platforms do not have corresponding Java wrappers.
Constructing a "Write once, run anywhere" Java application under these environments
requires maintenance of separate native source sets, and integrating a separate
build system for every platform has many shortcomings.
