Replacing faulty drive in OMV

I have a OMV box with two disks in RAID 1, mirroring, with one disk failing. This post describes the process. Write down, on paper, the serial number of the failing disk. If you are like me all your disks may well be the same brand/model, so serial number is important. Removing the failing disk… read more…
Auto-post to Facebook

Zoyinc is my “brand” and this is my site so when I decided to auto-post to Facebook I thought it would be straight forward, but it did quite work out that way. These are some of the tips I found out along the way, yes the info will date because Facebook is a constantly evolving… read more…
Color balance in Gimp using an eye dropper

Frequently you want to set the color balance for an image in Gimp but don’t want to do it manually. Fortunately it’s easy with Gimp using the eye dropper. Just select “Color | Levels” from the Gimp menu and you can see a dropper for selecting either a black, gray or while color point in… read more…
Run ESX from USB on old HP desktop

I have running VMware ESXi servers for years, sometimes at work on servers but recently at home on a whole bunch of older desktop machines. Not too many problems and when I did have problems it was usually about an unsupported network adaptor. Just a few weeks ago I tried to run ESX from USB… read more…
Scheduling a task in Open Media Vault

I need to run some scripts every night to move some files around in OMV. I want something that simple and easy to maintain and more or less stock standard. There are probably many variations on how this could be done but this is how I chose to do it. Before we start it is… read more…
DNS problems, email notifications not being sent

I had a working Open Media Vault system with notifications going out and then it stopped. OMV runs on Debian. In the log I started seeing: The actual error was: postfix/error[1443]: 1D96741676: to=<joe.blogs@domain.com>, relay=none, delay=175894, delays=175853/41/0/0.24, dsn=4.4.3, status=deferred (delivery temporarily suspended: Host or domain name not found.

Public facing web server on SonicWALL VLAN

I have a SonicWALL TZ 205w sitting behind my fibre connection with my web server running on an ESXi server connected to the SonicWALL via a VLAN to isolate it from my LAN. This has proved to be a bit of a mission because I don’t have a modem between the SonicWALL and the ONT,… read more…
ESX VLAN to SonicWALL DMZ

I have an ESX server on my LAN and I want to connect it to the DMZ on my SonicWALL using a VLAN as the ESX server only has one network adaptor. The SonicWALL is a TZ 205w which is connected to Fibre. This in itself was a challenge and is described in the post… read more…
Connect SonicWALL TZ205w to Fibre ONT

We recently got fibre to our house using Spark as the ISP and of course Chorus as the installer. The fibre terminates in the house at the ONT, optical network terminal. The ONT has an Ethernet RJ-45 socket that you connect to the Spark supplied Huawei HG659b modem. At the time I had a SonicWALL TZ170… read more…
Cloning an ESXi USB boot flash drive

I have a couple of ESXi servers at home that I boot from USB keys – see the post Running ESXi 5.1 from a USB key. The problem is that using a USB imaging tool doesn’t seem to work. When I boot up ESX I get an error: BANK5: invalid configuration. BANK6: not a VMware boot… read more…
