A Treasure Trove of Technology Tidbits
So, today I wanted to forward VMware ESXi host syslog data to my newly installed Splunk server. “No problem,” I thought to myself. But, strangely, my changes did not result in any actual data being collected. It turns out that the VMware firewall blocks outbound syslog by default, and so I had to change its […]
Today, I downloaded and installed Splunk (http://www.splunk.com) which is a “Security Information and Event Management” (SIEM) tool. Or, to put it another way, the big brother to a regular syslog server. Splunk is touted (by its company) as providing “Operational Intelligence” to normal IT functions like debugging why a web server went down, or what […]
During an upgrade of Exchange 2003 or 2007 to Exchange 2010, one of the tasks to be complete is the update of user, groups, contacts, and public folder objects. If you have not updated these objects, you will get warning messages every time you use the 2010 Exchange Management Console (EMC) to edit these objects. […]
I was working at a customer site who had recently upgraded from Exchange 2003 to Exchange 2010. When I went to edit one of their policies, I received an error message via the Exchange Management Console (EMC). Based upon this error, I realized that the policies had not been upgraded. Here is the step-by-step how […]
So, I was on the phone, trying to walk someone through some server debugging steps. But, after some phone support, it was clear that I needed to locate a hotspot and remote into the server myself. Once I got into the server, I wondered, “I asked for it to be rebooted, but did it actually […]
Today, I was upgrading a vCenter 5.0 server to vCenter 5.1. The first part of the upgrade process is to install the new VMware Single Sign On (SSO) service on the existing vCenter server. This part of the installation can easily happen during production times, because it does not effect access to the existing vCenter […]
So, today I needed to debug a performance problem I was having with my Linux virtual machine (vm). I was on the phone with a SAN vendor who had given me a performance testing program to install on linuxvm (don’t you just love my simplistic naming conventions?). But, the file was currently downloaded to my […]
I was trying to update the offline address book using the Exchange Management Console (EMC) and received an error which said: Action Update found not be performed on object Default Offline Address List. Failed to generate the content of the offline address book… two possible reasons for the failure are that the System Attendant Service […]
I just got back from some international travel. I had a great trip, met lots of different folks, and saw lots of amazing sites. The only items that came back with me was one green wool sweater and some pictures. The sweater was a result of misjudging the weather and being cold. The trip got […]
So, I have installed Blackberry Enterprise Server (BES) 5.03 from scratch several times. This week, I installed BES 5.04 for the first time. I am not sure if my installation error was the result of something specific to the Windows 2008R2 server, or if it’s a difference between BES 5.03 and 5.04. But, in any […]
