OpsView/Nagios check for Blacknight.ie Status Page

DateFriday, July 16, 2010 at 12:54PM

As part of my placement, we monitor websites hosted by Blacknight.ie.

If Blacknight are having issues we tend to get alerts messages about "Connection Refused" which tend to cause some consternation!

To cut down on the amount of clicking, I've wrote a small bash script that can be run by OpsView/Nagios that will check the Blacknight Status Page and return a count of the number of times that the "NOTOK" image is shown!

Recovering a corrupt LDAP DB on OS X Server

DateMonday, June 7, 2010 at 11:00PM

This weekend a problem arose with the OS X Server back home. I initially noticed it when I couldn't gain SSH access to the machine.

Using verbose output the SSH connection would reach the status of "entering interactive session" but would proceed no further.

When a user attempted to log on locally to the machine, even though the password and username were correct it would still display a logon failed message.


Using the local administrative account I determined that slapd wasn't starting up.

Here's my experience so far!

Connecting an Apple computer to the IT Sligo WiFi

DateThursday, February 4, 2010 at 4:20PM

Recently I met some people who said that Computer Services was unable to help them get their Mac OS X computers onto the student WiFi network in IT Sligo.

In this day and age, why isn't a college computer services dept. able to cater for Macs...

Anyhow, here's a PDF I've thrown together to instruct a user in how to do it. Leave me a comment if you need any help or more information.

Checking your IT Sligo Studentmail whilst avoiding webmail!

DateTuesday, January 19, 2010 at 5:28PM

Tired of using webmail to check your IT Sligo Studentmail? I know I am. Ideally they'd upgrade to Exchange 2007 and give us all nice access to our mail AND the college global address list. I think that sounds like it makes too much sense though. For now, you have to be content with IMAP/POP access.

If this sounds interesting to you read more!!

OS X Remote Management using a "man-in-the-middle" linux server

DateThursday, January 14, 2010 at 2:20AM

Occasionally some of my friends contact me asking for assistance with their Macs. Usually this help can be conveyed over the phone, but sometimes I couldn't be bothered trying to explain it all, I just do it myself!

How, you might ask, can I accomplish this when my friends are 2 hours away!
