tldr; This question was to get help setting up Micro Cloud Foundry on Windows XP behind a corporate firewall as an innovation-demonstration project for a Fortune 500 IT departent. Basically, the project stalled, despite this stackoverflow page - the magic wasn't strong enough. I am accepting #DanHigman answer below, but if anyone sees this and can provide a simple straight-forward answer, by all means...
Can anyone provide a clear step-by-step on setting up MCF on a Windows (XP in my case) machine behind a corporate firewall, for demostrating the feasibility of PaaS in the corporate IT world?
My VM is installed and running and I can use the menu ok. I have vmc working. I have a test Node.js server app, that works on local, ready to push. But I can't get past that stage.
The firewall gave me trouble so I lowered my goal to just work offline. I followed the instructions noted below as best I could, but often the instructions are mac oriented - I would like them for a Windows command line (especially SSH tunneling):

http://support.cloudfoundry.com/entries/20332921-micro-cloud-foundry-trouble-shooting-help
This blogger may have half-way covered my problem doing the SSH tunnel settings, but all it gives is "use Putty" - more detail would help:
http://support.cloudfoundry.com/entries/20419943-using-micro-cloud-locally
Also, whenever the vmc obviously gets an error or other message, it only outputs the following in the command line:
vmc target http://api.vcap.me
<<<
[200, "<html><body>SNP/2.0/102/Unknown Command 'info'</body></html>\r\n\r\n", {}
]
>>>
Thanks for any help. BTW - I know I could do this on my mac, the big obstacle is the windows and firewall environment.
Update:
#Dan and #ebottard: Thanks to your help, I'm almost there. ping is working now, hosts file seems right, but the vmc target api.vcap.me still does not find the VM at that 192.168.253.128 IP - even tho ping does. In the first link above, Martin wrote the following, but assuming we are doing it on a mac:
After the update is complete, you will need to make some changes on your local system. What you will need to do is to set up an SSH tunnel to access your Micro Cloud Foundry VM (note that you will need to supply the IP address in the command below with the actual IP of your VM, which is displayed in the console).
sudo ssh -L 80:192.168.168.149:80 vcap#192.168.168.149
Password:
vcap#192.168.168.149's password:Â
The first password being prompted is the sudo password for your machine, as it is needed to open port 80 which requires root privileges. The second password is the vcap user password which you entered during the initial configuration of your Micro Cloud Foundry.
I need to have these instructions translated into Windows, and all I have to go on is that I might use puTTy (which I have downloaded) to do it. Any more ideas?
Looks like you're running an application on your Windows machine called "Snarl" (a poor Windows-based clone of the OS 10 app Growl :-p). It looks like it's interfering with communication to the MCF intstance, close it and have another try.

I decided to try to run Cloud9 on an ARM server ("Graviton"). I created an EC2 t4g.medium instance and a key, made sure I could SSH into it as expected (no problem), and then created a Cloud9 SSH environment. It mostly seemed to install without issue aside from a mild complaint about Sqlite. When I opened the IDE, it was perfect. Terminals worked as expected, files saved, autoformatter autoformatted and the world was good.
Every subsequent time I have opened the IDE, however, it has just given me a loading spinner. After a lot of Googling I noted that this pattern has been seen before. I tried installing tmux, but that had no effect. See screenshot:
screenshot of cloud9 error message and spinning terminal
According to this document, graviton isn't officially supported: https://docs.aws.amazon.com/cloud9/latest/user-guide/ssh-settings.html#ssh-settings-requirements. Other things that might cause it to fail are if the instance isn't publicly accessible on the internet (ie on the public subset with port 22 open, or connectable through a jump host). Also, you'll probably want a security group that only allows traffic from Cloud9; see here: https://docs.aws.amazon.com/cloud9/latest/user-guide/ip-ranges.html.
Additionally, I found the Cloud9 installer doesn't mention needing to install gcc-c++ in addition to gcc.
Because I don't want my machine on the public subnet, I'm giving up and waiting until this is supported. But I hope this might give you some useful information.
I have a problem with a web service that is installed and started with a .msi that is created with the WiX toolset.
The service can be installed and started on all the machines I tested so far (shown as running in the Services Manager) but on some machines it is not reachable (for example via a browser) and not shown in the list of listening ports on that machine (displayed with 'netstat -a').
I am trying to figure out what's going wrong but I am not really familiar with web service development and configuration. It's a third party service, thus I don't know how it works internally.
A good starting point for me would be to find out, what exactly happens when a service is installed and started during the execution of the .msi-file.
Maybe I could try to tackle the problem on a lower level then.
Below is my code in the ServiceInstall-Element:
<ServiceInstall
Id="ServiceID"
Type="ownProcess"
Vital="yes"
Name="ServiceName"
DisplayName="ServiceDisplayName"
Description="Lorem Ipsum"
Start="auto"
Account="LocalSystem"
ErrorControl="normal"
Interactive="no"
Arguments="action=run">
</ServiceInstall>
The argument is important - without it, the service won't start or run.
Maybe someone else encounterd the same or a similar problem and can help me out.
Thanks already in advance - each hint is appreciated.
EDIT I (15.04.18):
As it might be a problem with the specific service, I will add some further information here:
It's a third party software called CryptoLicensing:
http://www.ssware.com/cryptolicensing/cryptolicensing_net.htm
Part of this software is that specific program, that serves as a License Server and does the license registration, for example in a customer's network.
The service can be run as a Windows application or installed and run as a Windows service. In both cases it should be listening on a (pre-)specified port on the installed machine.
Whenever I start the .exe as an application, everything works as intended. The service is reachable (for example with the browser) and can be accessed from other machines in the network.
When the .exe is installed and started as a service, it does not work as intended on every machine. For example if I install and start the service on my laptop, it is shown as running in the Services Manager, but is not reachable on its assigned URL (not even on the localhost) nor is the specific port displayed in the active listening ports, for example with 'netstat -a'.
The service itself starts without any error messages and does not log any errors or exceptions as it seems to be running without any problems.
I contacted the vendor, but sometimes he doesn't reply quickly and he is not very specific in his replies.
Before asking the question I assumed that it was a problem with the Windows user rights and the WiX installer but during the discussion here I had the feeling that it might a problem with the service itself.
I hope this 'new' piece of information helps in isolating and location the problem.
Thanks to everyone who helped so far!
Hopefully not stating the obvious here, but WiX doesn't do much except populate the ServiceInstall table in the MSI file, so this is about why Windows Installer won't start the service. ServiceInstall table:
https://msdn.microsoft.com/en-us/library/windows/desktop/aa371637(v=vs.85).aspx
Also, this isn't really about ServiceInstall - it's probably about the ServiceControl element in your WiX source, but it's not clear whether that's how you're starting it or if you're starting it manually later on. That does make a difference. What is the error message and where are you getting it, and is it a 1920 or 1921 error (in the context of ServiceControl).
The main reason a service will start on one system but not another is missing dependencies. If your service is C++ based (the post doesn't say) then there are probably dependencies on C runtimes, UCRT runtimes, MFC or ATL runtimes and so on.
First: are you sure this service is intended to run as LocalSystem? (MSDN, SO).
Second: did you check the event logs in detail for anything obvious? If the service is good you should find a hint at least. Something to start with. I find that I sometimes miss the actual logs in the event viewer because it is so "crowded". My take on it: empty the log and stop and restart the service.
Something locking / blocking: If the service installs and runs OK I would suspect other factors such as firewalls (hardware & software), security software in general (anti-virus, malware scanners), network configuration issues (proxies, WINS, DNS and all the complexities involved in networking). Is the service trying to reach an UNC path?
Diverse Machines: What are the target machines? Are they virtual, are they physical, are they test machines, are they operative SOE machines in corporate networks? Are they the same OS version and edition?
Further Ideas: It is not quite related, but maybe skim this list of suggestions for debugging from another answer (I am not sure why it was down-voted, I think it is an OK list to inspire debugging ideas): Windows Application Startup Error Exception code: 0xe0434352 (maybe just skim the bolded words for ideas - Recommended).
sc.exe: And finally, perhaps check the sc.exe tool (Service Control) and see if it can provide you with some useful information for debugging.
sc.exe in the context of killing hung services (sample use).
sc.exe from MSDN
Some further links:
Windows Services Frequently Asked Questions (FAQ). Content seems to be up to date - at face value at least. These guys claim to be experts on services. I have no idea who they are.
Essential Tools for Windows Services: SC.EXE
Run Service Control (sc.exe) command on secure port
After almost 20 months we finally (and accidentally) found a solution to the problem! For the few machines, on which the service did not run properly, setting the NoInteractiveServices value in the registry to 0 did the trick. A value of 1 (which is default) means that no service is allowed to run interactively, regardless of whether it has the SERVICE_INTERACTIVE_PROCESS property. More information on Interactive Services.
I am not completely satisfied with the solution, because on all the other machines NoInteractiveServices is set to 1 AND the service runs properly anyway. However, on the machines where the service did not run interactively this solution worked for us. Thus I will accept this as an answer.
If anyone has more information on this issue and can explain why this works, feel free to
add them - I would be very interested!
Using vSphere Update Manager I've installed some updates and patches onto my host, however I have an issue with it picking up a datastore now so I want to roll back these changes to see if that fixes the issue.
From my research I understand that you can't uninstall these patches and you have to revert back to a previous ESXi version. I'm attempting to do this following the steps here: https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1033604
However it does not give reference on how to access the Console for the Host. I can't find a way to access it in vSphere, but found a way by downloading putty and running the DCUI command.
The problem I have is that it says Reboot and then:
When the Hypervisor progress bar starts loading, press Shift+R.
However when I reboot putty loses connection to the host (presumably because it is rebooting) so I never get to see the boot up screen and Hypervisor progress bar to press Shift+R.
Am I missing something simple here? Server is Dell running ESXi 5.5. Thank you.
Dell ilo interface shall provide you the recover(Shift+R) while rebooting and hence rollback option.
The default credentials for dell ilo would be,
username : root
pwd : calvin
The steps to achieve this would be as follow,
Get ur ILO link, please see if below link is useful to you in this regard.
https://www.dell.com/community/Systems-Management/How-to-get-the-DRAC-IP-address-from-the-localhost/td-p/2374426
otherway would be ping your server FQDN and it would return the ILO IP.
Once you find ilo url or IP, login to it using above mentioned default login credentials(root/calvin).
Now, in ILO interface find the option to launch the console (server -> Virtual console preview -> Launch).
Save the JNLP file and run it.
Further, Press F12 for "Shout down /restart"
Here onward I believe you will get it.
Thanks,
Manjunath.
Normally I've developed locally (on my own machine) and pushed to wherever things needed to go via mapped drives, ftp, github, etc. I have done a bit of work with vagrant/virtualbox (but again, locally) with a shared/mirrored folder.
I am now in a situation where everyone here has access to their own dev box (a vm on the network). I see some working in Vim directly via SSH, I believe, but I'm not there yet. So I'm left with the question: What's the best way for (more of a front end guy) to approach this?
I have heard of doing an SSH-mount from my workstation... if that's a viable thing. I'm curious what everyone's take on this kind of environment is and (perhaps) any best practices. Tips, links, and reading is highly welcome and appreciated, too... any pointing in a good direction would be wonderful.
Thank you.
The best answer will come from what virtual resources do you want to capitalize on for the virtual networked VMs. If you just want the storage space, then share the VM's drives, and mount them locally, treat them as local, end of story. If you want to run all the processing on the remote machine, and connect from a thin client, you have a couple of options, but they all take the same form. Connect to the machine, edit the files on the remote machine. Depending on your OS, you will have different options available.
If the remote machine doesn't have an graphical client installed you are stuck with either, mounting the remote share locally (you can use whatever editor you want) or ssh to the remote machine and using a commandline editor (vim, nano, emacs).
If there is a graphical client installed you have more options:
Remote in the server using any visual viewer (mstsc for windows, vnc is an option), and then use any remotely installed editor of your choice.
Remote in using ssh -X, and then run the remotely installed editor. Assuming you have an X-Server locally (if you are running linux you already do), the GUI part of the application will be run on the client side of the ssh tunnel, and the process will be run on the server. This is probably the best option.
So:
Make sure the remote server has a desktop client software (gtk, kde, gnome, almost any windows os, etc...)
install GUI editor of your choice on that server
ssh -X to that server
install sublime text, geany, or your choice of editor
run subl, geany, or other to start the application.
SSH mounting would indeed allow you to use all of the files on the VM as if they were stored in your local machine, letting you edit and update files without having to manually copy them every time you perform changes. You will run into a speed bump though, since files changed will have to be synchronized/copied to your remote machine every time and that takes a couple of seconds. Check this post by DigitalOcean, they explain how to get the SSH mount working.
A better option you have (IMHO) is to use an IDE in your local machine that allows you to push changes to a server after saving or by manually doing so. This would allow you to develop faster by using your local resources (local web server) since no files would have to be copied over the network to the remote VM; and would also allow you to test on that remote VM when needed by uploading the files when you are ready to test on that environment.
PS: Exporting visual apps or environments form the remote machine to your local one can be slow (depending on your network and the VM host load running your machine). If you still like that approach, you could also install something to access that VM over something more standard and lightweight like RDP for GNU/Linux (xrdp).
I am a GIS tech trying to get migrate to Geoserver, unfortunately I am not very savvy on web hosting.
I installed the Windows version 2.3.1.
I was able to build by map and access it through localhost:8080\geoserver\www\
I take that to mean that the jetty server it working.
I understand that I should be able to replace my local IP address where "localhost" is and be able to access it from another computer via Http.
I can't figure out the next step. I have found great tutorials on every part of geoserver process except this. And the user guide does not get into this either.
My set up: Cable Modem > Router > PC with Geoserver
What I have tried: Setting up a virtual server on my router. I have tried changing by router to inbound port 8080 to private port 8080
I also tried 80 to 8080
and 80 to 80
I also tried windows firewall exception. and turning off windows firewall.
I read about using appache tomcat but I have not installed it because it seems that jetty is working (at least as a local host) and I don't want to put another program on 8080. And to my understanding it can work stand alone but I really honestly don't know no.
I am must be missing some vital piece of information on how to do this. I am hoping it is just so basic that it wasn't worth mentioning on tutorials.
Thanks

This would be a GeoServer configuration question, but since its deployed in jetty the solution is likely in the underlying jetty configuration. That being said it is a guess on my part (the jetty side of things) how they set up this distribution, but if you find a jetty.xml file, perhaps under an /etc directory then you should be able to edit that file and set a proper host in the configuration.
Seriously though, this has to be a pretty common GeoServer question so I bet they have some documentation floating around for setting this properly in their software distribution.
http://docs.geoserver.org/latest/en/user/webadmin/basics.html
That seems to indicate it might be dependent on your container configuration, in which case look through how ever they are configuring jetty for a Host setting that is likely hardcoded to 'localhost'
