Network Administration with AWK

If you are looking for an easy way to access your network services, AWK scripting provides the means.
Trade-Offs

We have seen that network access through a special device is good enough for many useful applications, but there are advanced features we have to trade off for this convenient access method. Some things are simply not possible within the easy-to-use framework AWK employs, namely:

  • broadcasting

  • non-blocking read

  • timeout

  • forking server processes

In spite of the lack of these advanced features, advanced applications such as a prototype “web server” or a “mobile agent” have been implemented in GNU AWK. If you need, and can handle, features like broadcasting or non-blocking read, you should use Perl or C instead of AWK.

Resources

Juergen Kahrs (juergen.kahrs@t-online.de) has used AWK on MS-DOS for time series analysis, statistical analysis and graphical presentation, mostly of neurological data. In 1996 he switched to Linux and enjoyed seeing his old scripts still running in a more efficient programming environment. He has come to peace with the fact that AWK will never be mainstream and enjoys seeing C programmers spend nights chasing NULL-pointer accesses. Juergen did the initial work for integrating TCP/IP support into gawk.

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
