Centos Firewall Source Rule Creation

This is useful for protecting your elasticsearch cluster.  Something like graylog should be the only thing that is able to connect to it outside of the other elasticsearch nodes. firewall-cmd --permanent --zone=public --add-rich-rule='rule family="ipv4" source address="" port protocol="tcp" port="9300" accept' firewall-cmd --reload


Excited I get to go to the VMUG USERCON this year.  I havn't been able to go in some time and really looking forward seeing what's up and coming. Maybe I can win one of those fancy home labs, either-way there's free beer.   BOSTON SUMMER VMUG USERCON

Horizon View and Windows 10 LTSB

If you have Windows 10 in a VDI environment you know the pains of trying to disable all of the junk you don't want running that is just wasting CPU\MEM and increasing logon times.  You can run the Optimization Tool but it can be finicky with disabling those pesky windows 10 features.

Like many people running exchange I run a report to check free space on the database volumes.  Interestingly it was only the mailbox server that was being backed up.  The environment...

Horizon View Desktops going offline

So I ran into an issue a while ago with my Horizon View non-persistant desktops. The issue was that they kept losing their DHCP lease and through the vCenter console you could see that they had APIPA addresses. In this environment we have a lot of churn in the VDI environment.  People will logon to... Continue Reading →

Microsoft Exchange OWA Banner

I recently went through a migration of Exchange 2010 to Exchange 2016.  One of the changes to the environment was the move to putting Exchange behind our SAML login platform ADFS 3.0.  One idea we had was to let our OWA users know right on the website.  Microsoft does not give a way to do...
