Halcyon.exe - This application could not be started | Asset Cache Initialization

[life777eternal]

Recently updated the ciphers(or disabled the old ciphers) on Windows Web Server 2008 R2, as per Vinhold Starbrook's instructions, and after several restarts, the Region consoles are showing, "The client and server cannot communicate, because they do not possess a common algorithm" and crashing. Although that could be because the Halcyon consoles 2-4 are crashing, and subsequently every region that tries to open after that. Though it's not recording any new error in the log.

The UserServer, GridServer, & GridMessagingServer have all been crashing. Apparently because they can't communicate with MySQL for some reason. Though I have the MySQL server and database back up and running now, so it shouldn't have any problem connecting to the database. All of my Osgrid OpenSim regions have no trouble connecting.

This application requires one of the following versions of the .NET Framework:

Do you want to install this .NET Framework version now?

Yes   No

This started after I had applied Vin's recommendation in the registry and group policy. Although I had SSL 2.0 and SSL 3.0 enabled for a short time so it could have been vulnerable to something during that time.

Manually doing the Above changes:
Disabling outdate TLS on Windows Server 2008 / 2012 R2:
Open the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\ 
Now we have to enable versions 1.1 and 1.2 of TLS. For this, we need to create new keys called 'TLS 1.1' and 'TLS 1.2' underneath the 'Protocols' key.
Once the key structure is created, you can proceed to creating a DWORD (32 bit) entry called 'DisabledByDefault' and set its value to '0' in each of the four keys: TLS 1.1/Client, TLS 1.1/Server, TLS 1.2/Client and TLS 1.2/Server.
For the TLS 1.0, TLS 1.1 set new DWORD DisabledByDefault=1 to disable them. Allow for TLS 1.2: DisabledByDefault=0

Apparently the AES-GCM Ciphers need to be above the AES-CBC Ciphers. (that's what Chat GPT indicated)

Two or three people have told me that I should update my server OS, and that's probably true. Although the folks who run the VPS company that my server is on have not yet setup a backup drive for me, so I can do a couple of in-place upgrades.

Thank you, Shalom.

My server does have .NET 4.8 but Halcyon and/or the OS seems to think it's not there for some reason or another.

Good morning,

So there are a couple of issues raised in one issue ticket. So let me address each one individually.

1. Server Operating System - Unfortunately, Microsoft Windows Server 2008 and Microsoft Windows Server 2008 R2 are no longer supported and recieving updates. This is due to the fact that they have reached the end of life for their support cycle (EOL). The end date for support according to Microsoft (https://learn.microsoft.com/en-us/lifecycle/products/windows-server-2008-r2) is as follows:
   • Start Date: October 22, 2009
   • Mainstream End Date: January 13, 2015
   • Extended Support End Date: January 14, 2020
     It is strongly recommended that you upgrade your server operating system to at least Windows Server 2022 to ensure you get the latest in quality updates which do include the latest security updates each month.
2. Issues finding .Net Framework 4.8 - When Windows Update installs updates including a new version of the .Net Framework, it will pull the latest version of that major framework version. For example if at the time, you reinstall Windows and do your Windows Update, and the latest version of .Net Framework 4.8 available is .Net 4.8.2 it will install that version instead of the .Net Framework 4.8.0 because it is set to download the installer for the latest version. To fix the issue of .Net 4.8 not being found, you will need to uninstall the version of .Net 4.8 currently installed and then get the offline installer for .Net 4.8 from: https://support.microsoft.com/en-us/topic/microsoft-net-framework-4-8-offline-installer-for-windows-9d23f658-3b97-68ab-d013-aa3c3e7495e0 and install manually. Then run Windows Update after. That should resolve the error regarding .Net Framework 4.8
3. Issues with mismatched ciphers - Unfortunately, I do not know what the intial reasopn was for you recieving the advice to change your ciphers on Windows Server 2008. However, usually you should not need to change the ciphers. In fact, by changing the ciphers you do risk it affecting other services such as Remote Desktop Protocol (RDP) and other various services that rely on those ciphers that comes with Windows. Generally, Network and Server Administrators will not advise you to alter the ciphers the operating system has because it can cause unintended problems. Likewise, just because your altering something in the Windows registry, does not mean that it in fact will alter things that are also hardcoded deep within the Windows operating system. Modifying Windows is unfortunately a very perilous task which if you are unsure of what you are doing, you should not embark on. In my team's case, we have an internal Halcyon grid (which we refer to as internal test beds because they are not available to the public). Our test bed runs the grid services on Windows 2008 R2 but we run the Regions on WIndows Server 2022 with no issues. Initially we did run into the cipher mismatch issue, but we installed the MSBuild tools (which you can find here: https://visualstudio.microsoft.com/downloads/?q=build+tools and scroll down the page to the build tools) on the WIndows 2008 R2 server and pulled a fresh copy of the Halcyon source code and built it on the server. That worked for us and we were able to run Halcyon just fine without changing the ciphers. If you did not follow the recommendation in Item 1 which would solve your problem, then you will need to probably reinstall Windows Server 2008 R2 assuming you have a key or means to legally activate the operating system. Then you will need to install all of the required dependencies manually (i.e. .Net Frameworks, the required dependencies for IIS, etc. and then follow what has been provided here for building the Halcyon code base. This should resolve the issue with ciphers. You can however save a copy of your folders within your halcyon bin folder along with the configuration files locally while you reinstall. Also make sure you backup a copy of the database. Often it is advisable not to have your database server be on the same machine as your world services assuming it is within the network your server is part of.

I hope this helps at least a little bit.

Greetings @emperorstarfinder thank you for the information. Firstly, I am aware that it would be better to upgrade Windows Web Server 2008 R2, and I have the install ISO for Windows Server 2012 R2, just not a product key yet. Though a while ago I found an online company in Australia that can provide those at a lower cost, which was where I received a product key for Windows Web Server 2008 R2. Although Windows Server 2022 is still too expensive.

Secondly, I have not been able to contact a human at the VPS company that my Server is with, I tried three months ago, and still nothing now. Although I'll have to do at least two in-place upgrades. First to Windows Server 2012 R2, and then to Windows Server 2019.

And I have had Visual Studio Community 2019, and I had downloaded Visual Studio Community 2022. Although I noticed that it doesn't work on Windows Web Server 2008 R2. Also I'm not very familiar with Visual Studio yet.

Also you're right that changing the pre-set ciphers is a risk, the remote desktop connection was affected, and I had to connect with TightVNC to change some of it back so that I could connect again with RDC again.

Thank you, Shalom.

Good afternoon,

First regarding Windows Server 2022 licensing - Microsoft has moved to a Client Access License Model (CAL) which means they will quote you a price based on the specs you tell them and number of users / clients connecting to the server. However third party providers that are authorized to sell product keys for Windows Server 2022 are selling the Windows Server 2022 Standard Edition product key for as low as 28 USD. However, I cannot give you advise on where to purchase your key from. But I will say you should be cautious about the site you buy the key from as some sites have been known to give bad keys.

Depending on your hosting provider, some hosting providers will also provide pre-installed VPS services that have Windows Server 2022 all installed and activated. Usually they will not charge you extra for the license key but this will depend on the hosting provider.

Second regarding inability to get support from hosting provider - I am sorry to hear that your having issues getting an actual human to provide assistance at your hosting provider. some hosting providers just require you to file a support ticket through your account dashboard. Should you need assistance with finding a hosting provider, someone from my team may be able to assist.

Third regarding MSBuild Tools on Windows Server 2008 - You do not need to install the graphical user interface for Visual Studio 2022 (GUI) on Windows Server. You only need to scroll down close to the bottom of the page that I provided the link for and download the MSBuild Tools installer. The command line interface (CLI) for MSBuild will work. This however assumes you have Microsoft .Net Framework 3.5 all the way up to 4.8 installed on the server. Keep in mind you need to install each version of .Net Framework manually to make sure your system sees all required versions and not through the Windows Update service.

Fourth regarding changing of ciphers - Usually it is never recommended to alter an operating system if you are not the one who developed the operating system and its usually recommended even moreso with Windows. The reason is because operating systems are very complex by their nature and while people may be good at modifying things on the surface, even that has the potential of breaking things deeper in the operating system. Likewise when someone providing tech support tells you to alter things such as ciphers and it causes a loss of data, a breach from a hacker, etc. it can cause all kinds of legal headaches for both the owner (in this case you) and the person providing support.

I hope that helps at least a little bit.

[sonjamichelle]

Stepping in to provide my 2 cents on hosting providers. Not being able to contact a support person for three months is UNACCEPTABLE! LEAVE THEM!

I've been working with computers an IT going on 43 years, the trend of letting an AI or a barely knowledgeable "support agent" reading a script or decision tree that only went through 2 weeks of computer-based video training handle your "needs" is just getting out of hand!

Places that I have used in the past and have VERY good luck and support with are, Nocix, Vultr and Digital Ocean.

Vultr and Digital Ocean offer mainly VPS but do offer some bare metal or dedicated solutions. Though those tend to be pricey. Vultr is the only one that offers Windows OS option (2016-2022). The best part about Digital Ocean or Vultr is that you pay for what you use. You CAN spin up a server without money up front, see how it will work for you, and it all is good, keep on going. Or if it doesn't meet your needs, terminate it and only pay for the time you used.

Yes, Amazon and Microsft Azure are options too, but you NEED DEEP POCKETS!!!! They are NOT priced for a small business or personal user. Look what happened to InWorldz and their reliance on Amazon and Rackspace. From what I understand they dug themselves a $30,000 hole.

For bare metal, I personally and currently use Nocix. They have been really good to me since 2016, support usually respond to me within minutes!!! And that is just STANDARD support. You DO have to pay up front for your server, but it is YOUR sever, not shared. You get 5 IP address and 1TB of data transfer at 1Gbs. There are many OS choices, even VMWare and Proxmox.

I currently have an AMD Opteron Windows 2019 Server with a License I paid for back in Dec 2019 running my web server, mail server and a small OpenSim based grid. I even just spun up a Hyper-V instance to handle my FreePBX needs here in the near future. All for $25USD/month. They are based out of Kansas City here in the US. The server specs are nominal and meet my needs, but they DO have some pretty beefy server options from cheap to really expensive. A good Halcyon capable server will run you around $60-$100USD / month depending on your needs. That is just a BALLPARK wild assed, assumption on what you would need and what I have used in the past for my Halcyon grid.

https://www.vultr.com/

[emperorstarfinder]

Yes, Sonja does provide some good places that do provide good hosting. You can also check out A Dimension Beyond which does provide hosting for Halcyon worlds. They can be found:

https://adimensionbeyond.com/

You would however need to have a chat with them regarding prices. A Dimension Beyond is also out of Arizona in the US.

[life777eternal]

Thank you @sonjamichelle those are good suggestions, although I would prefer one based in the country I'm living in so I don't get continually varying monthly charges because of the currency conversions.

Also I have been able to get the MySQL errors, which are all the same, through the debug option now that I have Visual Studio 2019.

OpenSim.Grid.UserServer.Error.txt

OpenSim.Grid.GridServer.Error.txt

OpenSim.Grid.MessagingServer.Error.txt

Thank you, Shalom.

What version of MySQL are you running???

MySQL v8 and up have drastically changed the way users connect, exchange passwords and more that I can't recall off the top of my head.

I know that the last time I installed MySQL v8 for Halcyon I had to choose legacy support for passwords.

IIRC, this is no longer an option presented at install time.

Try to install v5, the last working version to allow legacy passwords.

All said, I would HIGHLY suggest ditching you current VPS as it seems they really don't care about their customers enough to provide support and contact.

As @emperorstarfinder has said, Windows 2008 is EOL! It is a security hole waiting to happen!

I understand the frustration of exchange rates but seeing that the Internet is worldwide, and MANY services are being run in countries with fewer laws, over-sight and such, expecting to ALWAYS have a suitable local provider is a little unrealistic these days.

Vultr has servers around the world. I'm not sure what their default currency is. I am based in the US, so I use USD. I would think they accept Euros as well, and they do have PayPal as well.

DigitalOcean has fewer options worldwide.

One that I didn't mention is OVH, they have servers in the US, Canada and Europe.

Though personally I tend them too expensive for what they offer compared to others.

Then there is Amazon AWS and Microsoft Azure with data centers worldwide. But prepare to open your wallet even further.

Quite honestly, an attempt to help has been offered. You DO have to cooperate with those that are trying to help, shutting them out for "petty" reasons or an unwillingness to change won't get you very far. This is at least my take on your responses.

If you want to run a grid you need to be able to keep up with the changes, do what is necessary to provide a secure environment and have the time, desire and ability to support that grid.

Trying to run a full-blown grid is NOT a one-man band type of operation. This holds true more so if you want a thriving commercial grid that brings in users and an income flow!!!

Again, my $1.50 on the situation, take it with a grain of salt, ignore it if you wish.

It's MySQL 8.0.26, technically the same version that I had before, which was running Halcyon fine on my server. And aye, I have the "default_authentication_plugin" set to "mysql_native_pass".

[Yichard]

I am in the process of removing all MySQL from my sites. The reason is that, when they change of versions they often change the syntaxes, each time requiring to rewrite the code. In a simple application like reading data for Internet pages, this already is a nuisance. On complex applications using MySQL in many places, I understand it must be a developer hell. I hope any future version of Halcyon will use a more stable database system.

[mdickson]

The connector library needs to be updated in the code to work with MySQL 8 correctly. Shouldn't require a ton of code changes as I dont think the api is different but the current one doesnt support the authentication methods v8 wants to use. Mike

Thank you @mdickson When I have MySQL 8.0.26 Server/Workbench installed, the MySQL Installer doesn't show any older version of the other components, so had to manually download the MySQL Connector C 6.0.2 from the website. So I just uninstalled the Connector C 8.0.26, and downloaded the Connector C 6.0.2, since that's what Vinhold has on the "WindowsServerSetup.txt". Although the MySQL Installer Community doesn't show the older version (Connector C 6.0.2) in it's list of installed items. Also was there a specific version of the Connector/NET needed? I have the Connector/NET 8.0.26, should I switch that to any other version?

Also I wouldn't know what part of the code would need to be changed to make the Connector C 8.0.26 or newer compatible, unless it's just a text based file that would have to be changed.

Thank you, Shalom.

[sonjamichelle]

The connector should MATCH the MySQL version.
