Is there an Amazon Web Services service which will translate ports, such as port 8001 to port 80?

I like to host multiple websites behind a single static IP address, and I use port forwarding to route the different ports to various web servers behind my firewall which does the port forwarding.

It would be nice if I could implement a table like this somewhere inside an AWS service:

Client requests mydomain.com:80 -> AWS Route 53 translates to 123.123.123.123:8001 -> My firewall port forwards 8001 to the web server inside the LAN.

If AWS does not offer this service, then is there another out of the box solution? I could write my own app to do this and run it on an EC2 instance, but I prefer to use an existing tool if one is available.

I have a VMware vSphere essentials license, which includes one license for vCenter Operations Manager Foundation. When I try to deploy the OVF template of vCenter Operations Manager Foundation, I get the error:

The OVF package requires support for vApps with multiple VMs." "Details: Line 68: Unsupported element 'VirtualSystemCollection'

Here's a screenshot of this error:

The exact filename is VMware-vcops-5.8.5.0-2532416-vapp.ova.

I cannot create a new vApp in the File > New menu, most likely because my license does not support vApps.

How can I deploy this OVF template with my license?

EDIT: So I'm being told in the first comment I should not seek to install the vCenter Operations Manager and only install the vCenter Server. Why did they specifically list the Operations Center under the Essentials Kit and link to it?

I use PM2 to run my node processes in production (on Ubuntu 14.04). After upgrading from node 0.12.x to nodejs 4.4.x, the command to run node(js) changed from node to nodejs. I followed the instructions on the nodesource distribution installation instructions.

curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash -
sudo apt-get install -y nodejs

PM2 still wants to call node, even though the newer version uses the command nodejs. I hacked it by replacing the node binary with a sim link like this:

mv /opt/bitnami/nodejs/bin/node /opt/bitnami/nodejs/bin/node.old
ln -s /usr/bin/nodejs /opt/bitnami/nodejs/bin/node

and this seems to work fine. But would prefer to simply change a config in PM2 to point to the new binary.

What is the best way to make pm2 compatible with an upgrade to nodejs 4.4.x?

Update: these are the places where node exists on this server

root@ip-172-30-1-190:/usr/bin# find / -name "node" -type f
/opt/bitnami/nodejs/bin/node
/var/lib/dpkg/alternatives/node
/usr/local/bin/node
/usr/local/n/versions/node/4.4.1/bin/node

I originally tried to upgrade node using npm and the n package using this tutorial, which accounts for the /usr/local/n/versions/node/4.4.1/bin/node line.

It would be nice to be able to convert a Lazy Zeroed disk to an Eager Zeroed disk after disk creation in VMware - is this possible?

I understand the basic difference between Thick Provision Lazy Zeroed and Thick Provision Eager Zeroed. I usually want to do Lazy Zero so I can create the disk faster. And the eager zeroed performance increase is not large in most circumstances.

However, it would be nice to make the disk Eager Zeroed after disk creation, perhaps as a background task.

How can I install MS Office on Windows Server 2008? The purpose would be to enable Quickbooks to be able to export to Excel.

Quickbooks is set up to run as a RemoteApp in a Terminal Server environment. The Quickbooks applicaiton senses whether or not Excel is installed and will not allow the user to create an Excel report unless Excel is actually installed on the client running Quickbooks.

Since the client and the server are the same machine in a Terminal Server environment, Excel must be installed on Windows Server for the Quickbooks Excel exporting feature to work in this setup.

There is no need to actually use Excel in a Terminal Services environment. We only need to generate the Excel files using the server, then we can use an installed version Excel on a regular Windows 7 machine to work with the Excel file.

MS Office does not normally install on Windows Server. Is there any way to buy a special license? Could we somehow fool Quickbooks into thinking Excel is installed, if that would work?

Is a DCHP scope range of x.x.x.100 to x.x.x.200 large enough for 65 dynamic hosts?

I manage a small windows domain which has grown some. We now have 65 hosts using a DHCP scope range of 100 ip addresses. Expanding the DHCP scope range is easy as the 10.0.0.0/8 subnet has plenty of expansion room, so I am asking for guidance on how much to expand. What is a minimum size to avoid congestion?

What is a good ratio of count of hosts to DHCP scope ip address count to avoid congestion?

I manage 3 windows servers for my dad's business, and occasionally they lock up. I work remotely and would like to send commands to the motherboard to reboot using the buttons on the chasis. I have access to the network remotely.

All 3 servers are Supermicro servers, and two are the X7DB models with a serial port on the front. Can I send a reboot command using a device through the serial port? Would such a command work even with the OS is locked up and unresponsive?

I write some Python and do a little BASH and DOS scripting, so I probably have enough skill so compose some commands. But I don't know where to start reading about this topic.

Ocassionally one of my remote windows servers locks up and must be restarted by pressing the restart button on the front of the case. Since I work remotely I call a coworker to press the button.

I would prefer to restart the machine remotely by cycling the power using a web-controlled smart relay switch (such as this). But I am concerned about harming the spinning disks with a power cycle.

Is cycling power worse for a server than pressing the reset button on the chasis?

My Aastra 6757i off-site voip phone locks up periodically, and I want to rule out a networking problem. Most of the time calls work fine, both placed and received calls. But sometimes the voip call freezes and the phone reboots. I have tried multiple identical voip phones. The phones inside the LAN never lock up, but phones moved outside the LAN in this configuration all lock up periodically.

The Aastra 6757i voip phone connects through the internet to a Zultys MX250 PBX in another US state. The MX250 is connected directly to the internet using its own static public IP. No firewall separates the MX 250 PBX from the internet except the specialized PBX software firewall (in the PBX and part of the PBX software).

The internet connection is good at both ends. Remote site has 20 Mbps down/ 5 Mbps up over a Comcast cable modem, and the PBX site has 3 Mbps down/ 3 Mbps up over a dedicated, bonded T1.

The Aastra voip phone is separated from the internet by a D-Link DIR-625 higher-end home router. The DIR-625 is the only device in between the off-site voip phone and the PBX.

The DIR-625 has SPI disabled, NAT endpoint filtering set to endpoint independant, TCP endpoint filtering set to endpoint independant, anti-spoof checking disabled, ALG disabled for SIP.

I recently put the phone on the home router's DMZ, but this change did not have any noticable effect.

Assuming the PBX is set up correctly, what can I do at my remote location to help my voip phone connect to the PBX? Are my home router's firewall settings correct?

What is a good way to reboot a list of windows computers on a windows domain? Assuming the windows domain controller does not have a service to do this, please make recomendations for a script.

Can I list the host names and iterate though the host names to send a restart command to each? Can I get a list of host names from the DHCP server running in a Windows 2008 box at the script's runtime?

My preferred scripting languages from most to least desirable are: PHP, javascript, Bash, Python (know very little), VB (know it but don't like it)

I recently tried to boot a virtual machine in Windows 7 Virtual PC after the .vhd file was created inside Hyper-V. But Win 7 Virtual PC would not completely boot the virtual computer.

Can a .vhd file created in Virtual PC run in a Hyper-V environment? Vice versa?

What is the difference between a .vhd file created in Hyper-V compared to a .vhd file created in Windows 7 Virtual PC?
