MUM Australia 2012 October 23-24


I just noticed that the AU MUM is online, though there are no vendors listed yet. Other than Andrew “now I can dance” Cox, who of you are going? Does anyone from that side of the world even read this blog. Since you are in Australia on the opposite side of the world, does that mean all of this txet si sdrawkcab?

Fiber Skinny Fingers

We have a lot of fiber LIUs with a lot of patches. We mostly use LC connectors these days and we tend to densely pack these guys in. This works great…usually. Once it is time to head back in and pull somehting out of the middle or insert a new patch in the middle, you will realize that your fat-man-fingers just don’t fit in there. In comes skinny fingers to the rescue.


The only down side to these things is the fact that they charge $60 for them.

    Cisco Recertified!

    I’m back to the land of the living! I’ve been studying hard for the last month and a half and really bearing down the last week and a half. Needless to say the last two days have been insane…my brain is broken right now. If you want to ask me any Cisco networking questions, do it this week…everything will fall out of my head soon 😉

    Replay Wireshark Captures With PlayCap

    I was recently testing some SNMP Traps being generated by a module I installed on a generator. All of a sudden my monitoring system quit alerting properly…:( I wanted to test rapidly while working on the alerts, but I’m no where near the generator, nor do I want to sit at the enclosure to generate the messages.

    I was already doing packet captures with wireshark to ensure that everything was being sent properly and that the contents of the packets were as they should be…if there were only some way to replay the captured packets. It just so happens that there is!

    PlayCap is a free app that will playback your wireshark captures…easy peasy!

    Choose your packets to be replayed by highlighting them.

    Click on Save As. Choose selected packet in the bottom left and save just those packets.

    Now load up your newly saved capture and click the play button...super easy.
