Repeating Header Rows in OpenOffice Calc

hubble-trace

There are times when one might wish to repeat the top row or a few rows when printing out a spreadsheet in Calc. This is a printing function, and you get to it by editing the print range.  In the Format menu, click on “Print Ranges” and then on “Edit…”

Format -> Print Ranges -> Edit...This opens a dialog where you can specifically set the ranges that get printed, starting with repeated rows.  The button on the far right of the dialog next to that form field lets you specifically click on the row or rows that you want to have repeat at the top of every page.Edit print range dialogWhat shows up in the box if you choose the first row is “$1.”  This is the first row, so that makes sense.  If you had chosen the first 2 rows, the content would be “$1:$2.”

Here is the evidence from an output file from a password generating script I am writing.

Nagios Plugins 1.4.16 Installation Notes

Even simple things are hard when you have never done them.
There is a pretty good How-to at http://nagios.sourceforge.net/docs/3_0/quickstart-ubuntu.html for installing Nagios, and plugins, generally. I use Debian, so there may be a few minor differences between an Ubuntu install and my installation on Debian. Mostly I wanted to add a few notes about issues I run into when adding a remote server to the nagios family. You have to do a few things that are not in the instructions.
Before you begin, make sure you have a C-language compiler installed as well as ‘make.’
# aptitude install gcc make
also, your ssl_version in Nagios-Plugins will fail if you do not have libssl-dev installed.
# aptitude install libssl-dev
Your make will continue to fail in an unhelpful manner if you do not now re-run your configure command.
[nagios-plugins-src-dir]$ ./configure --with-nagios-user=nagios --with-nagios-group=nagios
Then run make and it will run properly.
[nagios-plugins-src-dir]$ make
Run make install as root.
[nagios-plugins-src-dir]# make install
Change ownership of the nagios-installation directory to nagios.
# chown -R nagios:nagios /usr/local/nagios
The plugins live in the /usr/local/nagios/libexec folder.

Make sure your nagios@nagiosserver can shell into the nagios@remote-server without a pass-phrase or it will not be able to run "command_over_ssl." I am not yet running the NRE as I understand ssl well enough to use it.

Thanks to Dave Bonnell for the libssl-dev suggestion http://sourceforge.net/mailarchive/message.php?msg_id=29576799

Make sure you ssh into each remote server as nagios@nagiosserver to get past the "Add this server to known hosts" dialog, otherwise nagios will not be able to send test requests automatically.

Installing DSpace 1.7 on Ubuntu 10.04

Original wiki entry by

Peter Dietz.

The goal of this guide is to provide a simple path that will get a user up-and-running as quickly as possible. Peter Dietz did a great job with this, however there are issues about setting up DSpace on an Ubuntu 10.04LTS server that I didn’t think were covered well. This is not entirely surprising because there have been two Ubuntu releases since April of 2010, and it is at least because my company doesn’t set up servers on the bleeding edge of Ubuntu development. There may be a switch to Debian at some point. Debian Stable is even more stable than Ubuntu LTS, I must admit, but we are more comfortable with Ubuntu. Read more

Installing OpenSRF for Evergreen-ILS

I am installing Evergreen-ils and getting OpenSRF installed is the second step in the journey.

The Evergreen Project develops an open source ILS (integrated library system) used by approximately 800 libraries.  The software, also called Evergreen, is used by libraries to provide their public catalog interface as well as to manage back-of-house operations such as circulation (checkouts and checkins), acquisition of library materials, and (particularly in the case of Evergreen) sharing resources among groups of libraries.

Is your cloud full of holes?

I am working up a site which lets people anonymously compare their security practices with current industry best practices and possibly to crosslink with regulations and PCI requirements. The first section is going to be about Cloud Computing practices.
Please comment and help.
This is going to be useful for almost everybody. People are so close to their own network that they may not be able to see where they are not following best practices and they may not even know what those practices are.
I am using the reference practices from various sources, as well as my own experience. I want to have as many people in the final project as possible, as it will make more networks more secure.
