So recently I switched from Linux to Windows (I regret it alot) - of course for school - and I have a project, but I need to start a local webserver. I can do this on linux, with Samba, but on windows i have no idea how to do it.
Also, how can I do it with Admin. I have admin on my computer.
Thanks,

I have in my Win32 application WM-KILLFOCUS hanging procedure. If I try to debug and test them proper function, windows lost focus on each breakpoints. Because focus gets Visual Studio window. Is here some way, how debugging application without focus losing?
(The same problem is with mouse moving, etc.)
Sorry about the late reply - I've been v busy - but here's a brief writeup about how to debug in a VM (as per the comments above).
Download and install suitable VM software on your development machine. I use VMware Player. This is free for non-commercial use, but if you are using it in a commercial setting please buy a copy (it is not expensive).
Create a new Virtual Machine, configured roughly as follows:
memory 6GB or so (hopefully you can spare that much)
disk space 100GB (don't worry if this sounds overly large - the file that backs the virtual disk will grow as needed)
network adapter bridged (important!)
Install Windows in the VM - from an ISO image (you can use Microsoft's Media Creation Tool to do this). This need to be Windows 10, VMware Player doesn't support Windows 11.
Once that is up and running, install the Visual Studio Remote Debuggung Tools in the VM.
Copy your binary/ies (and maybe your .PDB file/s, I don't recall if these are needed) to the VM.
Launch your app in the VM and fire up the remote debugging tools there. Then configure these for 'no security' (this makes it easier to establish a connection, and, since you're presumably in a secure environment, it's safe enough).
Connect to the Remote Debugger running in the VM from VS on the host machine. You will need to know the VM's IP address (you can find out what that is by running ipconfig in the VM).
In VS, select the application to debug.
You should now be up and running and you should have all the awesome features of the VS debugger available to you. Any problems or questions, please feel free to ask (the last few steps are a bit hazy in my mind, but I've done my best and if you can't find your way through it I'll research this a bit more).
Good luck!
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've got a decent PC that I'd like to install xenserver on, but it's also my primary workstation. Wondering if it's possible to access guests directly from the host machine -- meaning, can I use the monitor, input devices, etc that are attached to the host, to interact with the guests.
Currently setup as a dual boot Linux and Windows machine. I need them both running simultaneously while still being able to treat the host like a workstation. Already using Virtualbox, which is great but not what I'm aiming for.
I've searched high and low for an answer to this question. Maybe I wasn't searching with the right terms. I've found a package in the Ubuntu repos that adds an entry in grub along the lines of 'Ubuntu with Xen Hypervisor', but that was on a test machine that couldn't actually run Xen.
Normally, I'd just wipe this puppy and find out for myself, but there are really good reasons why I can't just jump into it this time, so I'm turning to the community.
Thanks for any and all info!
You can use a simple text console on the host to interact with the guests
xe console vm=guest
but I don't know of a way to access a graphical interface from the host.
Does anyone have a good way to set up multiple CFML engines, and versions of them, together in a suitable environment for cross testing a CFML based application.
Ideally, I'd like this to be Ubuntu Server based as I'm using it with VirtualBox (under Windows 7). Plus it'd be helpful if it was possible to switch between, so my laptop can cope with one at a time rather than all running at once. I'm thinking of the following:
Adobe ColdFusion 9
Adobe ColdFusion 10
Railo 3.3.x
Railo 4.x
OpenBD 2.x
I'd also like to get them serving from the same shared directory, so I don't have to have a copy of the code for each engine. Cheers
You mentioned being able to "switch between, so my laptop can cope with one at a time rather than all running at once", I'm guessing that you are thinking that each one will run on a different VM, or that they might require a huge amount of memory. I don't think you need to worry about that. Unless you require that they be on different machines, I think you could do this all on one VM and with one instance of a servlet container (like Tomcat).
From a high-level view, here is how I would do it.
Install Tomcat
Create or download .wars for each of the engines.
Deploy said .wars to that one instance of Tomcat
Set up Tomcat to use each of those servlets from a different host name (server.xml)
Create a code directory outside of Tomcat for your one copy of the code
Set up a Symbolic link in each webapp to link the code folder into the servlet
You should then be able to hit the same source from each engine by visiting the different host names in the browser.
I may be missing something. It has been a long time since I set something like this up. You'll likely need to make a bunch of tweaks (JVM settings, switching to Sun/ORACLE JVM vs. OpenJDK, etc).
I don't think running this many engines will cause you great trouble. In my experiences, for development, I have had 3 instances of CF9 running on Tomcat using only 189mb of RAM. And each additional instance did not increase that number by 1/3. Far less. It would not surprise me if you could run all of those handily with less than 512md of RAM. Possibly even 256mb if you are really hurting on memory.
I hope this helps.
For ColdFusion 10, Railo and OpenBD you would be looking at deploying with standalone installations of Tomcat, Jetty or JBoss.
ColdFusion 9, probably the easiest solution is "Enterprise Multiserver configuration" setup.
With these kinds of installation they are pretty much platform agnostic.
The things to be aware of are the web server, proxy and jndi ports that are used by each installation, but only if you want to run more than one server at a time.
After that it's whether you are bothered about proxying from apache or Nginx to the server instances and the connector you want to use.
No idea if this helps...
Since you've mentioned the VirtualBox, I'll share my personal approach to this task. It includes few fairly simple steps:
Install Ubuntu Server as VirtualBox guest (host is also Ubuntu).
Set up only basic software like JVM and updates. Set up virtual
machine networking as bridged adapter to use my Wi-Fi connection.
Configure my Wi-Fi router DHCP to assign static IP for MAC address of the virtual machine.
Add entry to my (host) system hosts: ip_assigned_to_vm virtual.ubuntu
Set up guest additions and mount my ~/www directory inside the machine to access web applications.
Now, when I need another machine for experiments, or some other configuration of software (I've tested ACF 10 and Railo 4 this way) I do two things:
Clone existing clean machine.
Make sure it is using the same MAC address with bridged interface.
That's it.
It doesn't matter which of the machines I run, they all can be accessed as http://virtual.ubuntu (of course, it requires proper web-server configuration on the guest). Same time they are independent and it is completely safe to make anything I wish and test anything that runs on Ubuntu.
Obvious downsides are that I can run just one machine at a time, plus much more disk space is used. Not a problem to me.
I've tried approach with Tomcat and multiple WARs, but it has couple of issues: I can't use different JVM and Tomcat settings, also if I screw the setup -- all the Tomcat hosts are down.
Hope this helps.

Background:
I'm running a full-time job and a part-time job in the weekends, and both my employers have supplied a laptop for me to work on. Of course I also have my powerful workstation at home to work from, and sometimes when I'm at the office at my weekend job (it's in another city) I'm working from yet another workstation.
Problem:
That makes a full 4 PC's I'm maintaining (software versions, licences and settings) just to do my work, and believe me, my list of prefered software is way too big.
I want to setup a Virtual Desktop on my VMware server, so I can work from the same installation and same session no matter which PC I'm working from.
Now I don't have the time and money to go through a full test of each setup, so I'd like to hear your experiences on the subject.
Question:
Should I use a VMware virtual workstation with some remote logon software (like realVNC, teamviewer, logmein, whatever...) or should I invest in a full VDI system like Sun or VMware provide?
Edit:
I'm programming in Adobe Dreamweaver on Windows XP - but I run my servers on Debian and sometimes do quick edits in VIM too. First I intend to virtualize a WinXP with base installation, to see how it runs.
I am a consultant and tend to work in a variety of environments. I carry a Thinkpad running VMWare Server over Ubuntu64 with 4GB of RAM. I've got a 320GB secondary hard drive that I use just for VM's and have 25 or so different virtual machines that I boot up as the circumstances demand.
They're a mix of Linux servers and workstations, Vista workstations and XP Workstations. I rarely use the VMWare server console. I access every one of them via one of the remote access methods.
For Linux, I usually install FreeNX or NXServer for desktop access and just SSH for commandline. On Windows, I always use Remote Desktop (RDP), but, on XP, that only works on the "Pro" versions, not the "Home" versions. If all else fails, I install VNC and use that. VNC is at the bottom of my list because it really is a last resort. The only thing it's better than is not actually being able to use the machine.
However, NX on Linux and RDP on Windows work WAY better than VNC. Other than little things like font smoothing and fancy desktop effects, the only big glitch would be if you are doing much with video or audio or DirectX-based stuff. Things like YouTube or other video do NOT like to work with any remote desktop protocol that I know of.
As far as performance, using Linux as a host for VMWare provides really good management of system resources. The Windows-based VM's aren't able to just gobble up memory, but still get it when they need to.
I do C# development all day in a virtual Vista workstation on Visual Studio 2008 and have absolutely no problems having 3-4 different solutions all open at once along with the normal stuff alongside over RDP on another machine, connected via wireless VPN.
I can flip over to the host OS and it won't even be touching swap space at all. As far as I'm concerned, it's a great way to work.
If you want to work with the same installation, you should seriously consider the Remote Desktop Server/Client solution, bundled into every windows OS from XP. Basically, this app displays the view from your remote desktop to your local one, using highly compressed images; this works even via low-bandwidth internet connections
While the XP version can only handle one user simultaneously, the one in Windows Server 2003 (and in Windows Server 2008, I presume) can handle multiple users (up to a certain limit).
Disadvantages, and side-effects include:
virtual pc via RDC is slow
anything using the 3d acceleration will be slow (at least using XP/2003)
Personally, I would go down the route of using a virtual workstation with some remote logon software. The network performance of VMWare has always been good in my experience, and depending on the OS, there may be a decent remote logon provided.
I guess you can live with Logmein Free. [Or Pro if u want those features]
Well, you don't say what OSs are involved, so.....
For windows, I find that Remote Desktop works as well or better than anything else, although if you pay for the RealVNC version with the mirror driver, that's supposed to be as good.
For off site access for windows, www.logmein.com (the free version) works very well.
If Unixes are involved, then VNC is definitely the way to go, there are various solutions for doing this remotely. Everything from redirection servers, to just forwarding a port in your firewall to an ssh server and setting up the various tunnels.
Performance of VMWare is very good, and I can run a SQL Server slice, a web server slice and develop on my laptop simultaneously. The VM slices reside on a USB 2 portable drive and make it easy to port between my laptop and desktop.
VM Console works well for accessing each environment, and depending on the configuration you set up with NAT vs. Bridging you can UNC to shares on slice.
The nice by-product of this is that should you host machine take a nose dive you can quickly recover your development environment.
