XymonQV – Xymon Android App

Upon purchasing a new phone, I discovered that XymonQV was no longer in the Google Play store and the link on GitHub was 404.

I was able to export the installed app from an old phone.

If you need the XymonQV Android App, you download it here:   XymonQV Android App

This is a copy of the app that was installed from the Google Play store and has not been modified in any way.

You are receiving these errors:

Your system is definitely storing passwords in the new format.     You are going crazy because your database is offline.

Windows 2012 R2 SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (xen.sys)

xen.sys

You are trying to start a Windows 2012 R2 server on a VMware infrastructure.

What you do (or don’t) realize is that this VM is heavily tainted by a Citrix Xen basket of fun.

Procedure to fix this tediosity:

  1.  Snapshot the VM
  2. Boot into Safe Mode
  3. Open Device Manager (Show Hidden Devices)
  4. Go through each section and delete all Xen devices (yes, to delete driver)
  5. Reboot.   The machine should boot normally without safe mode.
  6. Control Panel -> Remove Programs
  7. Remove ALL of the Citrix programs and drivers
  8. Install VMware tools

You have just been saved hours of agony.

Are you looking to migrate your XEN VMs to VMware? Contact VMDK Hosting.

Call “HostFirewallSystem.UpdateRuleset” for object firewallSystem

This error occurs when there is a problem with an IP in one of the services located in ESXi firewall.

The IPs entered into the GUI will all look correct and you have exhausted all possibility.

The root cause is usually that you have entered individual IPs in CIDR format with a /32.   ESXi does not like this.

How to correct the problem:

1)  SSH to the ESXi host and edit /etc/vmware/esx.conf

2) Remove the /32 from all IP entries for the firewall (see below).   Be sure to leave all larger CIDR annotations in place (/24, /27, /28, /16, etc.)

3) Reboot!

 

/firewall/services/webAccess/allowedip[0000]/ipstr = “192.168.10.10/32”  <- Bad Entry – remove the /32
/firewall/services/webAccess/allowedip[0001]/ipstr = “10.10.20.0/24”  <- Good Entry
