It seems like we have been having to create random passwords at work a lot lately.  So I decided to find a script that I could use on here (Password…

Earlier this week I started getting alerts that our Exchange 2013 server was running low on disk space for our transaction logs.  When I started looking at the drive, I…

There have time that we want to test file transfer speeds across our network.  The problem is we need to use a known file size to make sure we can use the same size data in each test.

On Linux and Mac systems you can use the following commands:

300MB file (random data):  dd if=/dev/urandom of=300mb.log bs=1024 count=307200
300MB file (zero data):  dd if=/dev/zero of=300mb.log bs=1024 count=307200

So at work we have been setting up Nagios XI, Nagios Network Analyzer, and Nagios Log Server.  One of the tasks was to get all of the switches to send their syslog messages to the Nagios Log Server.  However, it was set to allow syslog messages to come in on TCP/UDP port 5544 instead of the default UDP514.  So I started looking at how I could change the default syslog port on the switches.

So at work we have a couple of computer setup in a public area that can be used to access our web site.  In the past we have used Windows XP and locked them down.  However, with support for XP coming to an end we needed to come up with another solution.  I wanted to branch out a bit (at least for me) and come up with a kiosk setup that used a Linux distro .  I came across  some really good options, but one of the requirements was that the browser should be Google Chrome.  Most of the sites I came across used FireFox as the browser.  I spent a few weeks searching and testing and finally came up with a working solution that uses Ubuntu 14.0.4LTS Desktop (x64), Openbox, and Google Chrome.  I used information from the web sites listed below to come up with this working kiosk.

We have several room resources in our Exchange 2013 environment.  Occasionally, we need to make changes so new people can actually see what appointments are scheduled and not just see “busy” in the time slot.  I used to be able to make these changes via Exchange Management Console in previous versions of Exchange; however, it looks like I have to go to Exchange Management Shell now.

Wow, where have the past 5 months gone?  It’s hard to believe that 2014 is about half over already.  It has been an up and down first half of the year.  Work has been good, but I haven’t had any major projects going on that I’ve needed post about on here for future reference.  I guess that is kind of good and bad.  I kind of expect that will be changing some in the next few weeks.  So please come back periodically and see if anything has changed.

Exchange LogoToday we had someone make a request for a few users to be able to see what appointments were scheduled for some room resources.  They didn’t want these people to add any appointments, but just needed to be able to see what was scheduled rather than seeing “Busy”.  I came across this site which has the PowerShell commands to set the Reviewer permission.  The article talks about changing the Default user permission which is not what I wanted to do.  So I used add–mailboxfolderpermission cmdlet instead of the set-mailboxfolderpermission cmdlet.
