Enabling HSTS and SSL Redirection for Tomcat 9.x

This document details how to enable HSTS and SSL redirection (by default port 80 to 443) on a Tomcat 9.x instance. This will not work on 8.x versions of Tomcat because they changed some of the keywords for some reason.

Enable HSTS

Enabling HSTS (to include maxAgeSeconds = 31536000, includeSubDomains, and preload) requires two modifications of the Tomcat’s conf/web.xml file:
1. First, to enable HSTS support, Continue Reading

Merging directories in command line in Linux is a pain because the native mv command will not allow recursive overwriting.  So if we want to merge two directories, a lot of people like to suggest either using cp or rsync to copy over files and then delete the source files. Another way is to use a shell command to recursively run the move operation on each file in the source directory and mv it to the destination directory/subdirectory. I like this approach more because then you can add in arbitrary rules for which files to copy.

You can use this SQL QUERY to find all the forms for the entities in your CRM database. If you keep having duplicate Quick Create or Information forms come up, you can just look at this and see which forms have duplicate Type forms.

SQL Query:
USE YOURORGHERE_MSCRM
SELECT form.Type, form.ObjectTypeCode, e.Name, form.Name, IsDefault, form.IsCustomizable, form.PublishedOn, form.IntroducedVersion
FROM SystemForm as form
INNER JOIN Entity e ON form.ObjectTypeCode = e.ObjectTypeCode
WHERE FormPresentation = 1 AND FormActivationState = 1 AND Form.CanBeDeleted = 1 AND form.IsManaged = 0 -- just get unmanaged ones
ORDER BY form.ObjectTypeCode DESC

Backstory:
I recently switched web hosts from Digital Ocean to OVH. I decided to go the Docker route and hopefully make migration less of a pain in the future. I run 4 websites off of the host, 3 of which are WordPress and 1 Koken site for photography. I don’t think it was less of a pain to do this, but I had to finish it once I started it.

Go directly to Customizations page in new window:
javascript:window.open($(‘#crmContentPanel iframe:not([style*=\”visibility: hidden\”])’)[0].contentWindow.Xrm.Page.context.getClientUrl() + “/tools/solution/edit.aspx?id=%7bfd140aaf-4df4-11dd-bd17-0019b9312238%7d#”);

Go to Solutions in new window:
javascript:window.open($(‘#crmContentPanel iframe:not([style*=\”visibility: hidden\”])’)[0].contentWindow.Xrm.Page.context.getClientUrl() + “/main.aspx?Origin=Portal&page=Settings&area=nav_solution”);

Go to Security in new window:
javascript:debugger;window.open($(‘#crmContentPanel iframe:not([style*=\”visibility: hidden\”])’)[0].contentWindow.Xrm.Page.context.getClientUrl() + “/tools/AdminSecurity/adminsecurity_area.aspx”);

Get a Solution’s Dependencies in new window:
javascript: try { var cont = frames[1] || frames[0]; window.open(cont.Xrm.Page.context.getClientUrl() + “/tools/dependency/dependencyviewdialog.aspx?objectid=” + cont.APP_SOLUTION_ID.substring(1,37) + “&objecttype=7100&operationtype=dependenciesforuninstall”); } catch (e) { if (console && console.log) { console.log(“Error occured: ” + e); }}

Get a Record’s ID:
javascript:var thisXrm; for (var i = 0; i<5; i++) { try {var wf = window.frames; if (wf[i] && wf[i].Xrm && wf[i].Xrm.Page && wf[i].Xrm.Page.data != null) {thisXrm = wf[0].Xrm; var id = thisXrm.Page.data.entity.getId(); if (id) { clipboardData.setData(“Text”, id.toString()); alert(id); } else { alert(‘No id yet!’); } }} catch (e) { }}

Get a form’s type code:
javascript: var typeCode = frames[0].Xrm.Page.context.getQueryStringParameters().etc; if (typeCode) { clipboardData.setData(“Text”, typeCode.toString()); alert(typeCode); }

Setting a value on a rollup field is impossible in JavaScript in CRM 2015. You can’t refresh the field individually without clicking the Refresh button — which can be a pain for users if you have several rollup fields to recalculate.

function setValueOnRollup(field, value) {
//unsupported way of putting a value in the calculated field
//DOES NOT update the value in CRM, only on the display
$('#' + field).find('.rollup').find('span')[0].textContent = value;
}

So if you wanted to use it on a form, put setValueOnRollup(‘yourfieldhere’, ‘100.00’)

It’s best used when you have the values you want to show (preferably the real values) which can be retrieved with a query you can make with CRM REST Builder (https://crmrestbuilder.codeplex.com/).

These also might come in handy to manage the rollups and processes:

Process.js – CRM 2013/2015 Call Action, Workflow, or Dialog from JavaScript (https://processjs.codeplex.com/) is a cool tool to run a process from your custom JavaScript.

Dynamics CRM 2016 Workflow Tools (https://msdyncrmworkflowtools.codeplex.com/), specifically the “Force Calculate Rollup Field” feature to update the value in CRM.

If you’ve ever had this error pop up when deleting a managed solution on your CRM 2015 box:

The Main() component cannot be deleted because it is referenced by 1 other components. For a list of referenced components, use the RetrieveDependenciesForDeleteRequest.

You should use this to quickly get the dependency information:

First, go to the solution’s URL (will be like https://CONTOSO.CO/COCO/tools/solution/edit.aspx?id=%7b2BE0D3AD-DF66-4747-8AA0-A5BA16B146D3%7d

Then run this bookmarklet, which I call GetSolutionDependencies:

javascript: try { var cont = frames[1] || frames[0]; window.open(cont.Xrm.Page.context.getClientUrl() + "/tools/dependency/dependencyviewdialog.aspx?objectid=" + cont.APP_SOLUTION_ID.substring(1,37) + "&objecttype=7100&operationtype=dependenciesforuninstall"); } catch (e) { if (console && console.log) { console.log("Error occured: " + e); }}

It will extract the id for that solution, then go to a page in your CRM org to show more details.  Only tested in IE11 so the context may differ of course.

I recently had a hard drive failure while transitioning to an aufs/snapraid configuration using OMV on my Proxmox box.  I ended up losing about 3TB of data, of which 800GB was not backed up on another device in my network. Ouch.  Fortunately I had Crashplan Pro running for the past few years and backing up everything.

I first started using the Crashplan Restore option in my Windows 8 box but was constrained to having it run at between 6 – 10 mbps, which was estimated to take over a week to restore all of the data. I spoke with Crashplan support and they said this was normal as I was sharing the line and resources with other users.  Fine, I thought, but I don’t want to keep my primary Windows computer on for days on end when I could just setup one of my VMs on my headless server to do the work.  I had left it running for a few days already but only received about 200GB of data.

Surprisingly when I setup my OMV box to use Crashplan’s GUI by installing LXDE and the Crashplan application my download speeds skyrocketed to saturate my entire 50mbps line! I was surprised to see over 500GB downloaded in a single day through my OMV box.  I thought I would share this for those who might be restoring a huge quantity of data but complain about slow speeds on their Windows box.  I wasn’t able to resume the existing progress from my Windows box — so I ended up overwriting the 200GB that Crashplan had already downloaded in Window — but the speed more than made up for it.

I dedicated 3 CPUs and 8GB of RAM to my OMV box while it’s doing this and it’s eating up about 30-50% of my CPU while it does this.  Not too shabby!

Here is OMV (Open Media Vault) information main page: http://www.openmediavault.org/

I’ve been tinkering with Proxmox VE for holding my Linux NAS and media file server (OpenMediaVault [OMV]) in addition to some other Linux containers.  As OMV would be the only VM to access some of these disks I scoured the web for how to add a physical disk to a VM (http://forum.proxmox.com/archive/index.php/t-6192.html).

The problem with using /dev/sdX to pass through is that oftentimes the hard drives will change their X value (sometimes my primary will be on /dev/sda and othertimes /dev/sdg).  I couldn’t find an easy way to point it to the disk itself rather than its symbolic link that didn’t involve messing with udev & udevadm in the Proxmox forums or documentation, but I did discover that you can point QM (in the vm.conf file such as 101.conf, 102.conf, etc.).

Basically, do this in the Proxmox Console or an SSH session:

ls -l /dev/disk/by-id
# Look for the hard drive disk (not the partitions which will be appended with part-1 and so forth).
#In my example I found scsi-SATA_ST5000VN000-1H4_Z111111
#Then go into your vm.conf file (i.e. nano /etc/pve/qemu-server/101.conf) and add it manually to the device type and number that you want to passthrough.
#Here is what you would add to have it on the 6th SCSI device (scsi5)
scsi5: /dev/disk/by-id/scsi-SATA_ST5000VN000-1H4_Z111111
#Save the file and you should now see the disk when you look at the VM in Proxmox.

Such an easy solution but it took me a few hours of messing with udev to figure out.
