Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I'm writing this up because I've often seen the question "How do I extract email attachments at command line?". I had to figure out how to use various tools to do this recently and figured I'd share what I did.
While what is written below certainly works for extracting email attachments including those sent by OSN it turns out Oracle does NOT include all fields in the email they send so we ultimately abandoned this setup for OSN and are instead...
OK - This isn't really Linux but is related to work I do as a System Admin wherein we use Cisco DCNM (Fabric Manager) to manage our Cisco MDS 9513 SAN switches. In addition to installing the Fabric Manager jnlp on our local Windows 7 workstations we install the Device Manager jnlp (element-manager.jnlp).
We did a recent upgrade to DCNM 6.2(5a) on our main Fabric Manager server (Windows 2008 R2) and upgraded the switches to 6.2(5) version of NX-OS. (One must run a version of DCNM/Fabric...
We recently setup a couple of new DMZ servers so decided to use zones "internal" and "external" rather than zone "public" (which RHEL7 uses by default). We also set "internal" as the "default" in firewalld.
We used firewall-cmd to assign our em1 interface (this is first embedded NIC, on some systems this might still be eth0 instead) to the external zone. We then assigned em2 (second embedded NIC, this might be eth1 instead)...
Posting this because all I found on line were multiple links to a single google post about this error.
On a RHEL5.10 system this morning I did a "dig" and got the error:
timer.c:331: fatal error: RUNTIME_CHECK(isc_time_now((&now)) == 0) failed
Clearly the message is related to time and in the US this past weekend we switched to daylight saving time (in my case we went from EST to EDT). Initially I thought it was because the system I was on didn't...
