I wanto to add startup script to windows VM instance Google (windows server 2012 datacenter).
I added statup script by custom metadata:
Key: startup-script
Value: #!/bin/bash mkdir C:\newfolder
But, it was not working. No folder was created in C: disk.
Serial port 1 (console) output:
2018/05/10 07:07:51 GCEMetadataScripts: Starting startup scripts (version 4.1.6#1).
2018/05/10 07:07:51 GCEMetadataScripts: No startup scripts to run.
Please help.
I think you have to use the Windows specific keys like windows-startup-script-ps1.
See https://cloud.google.com/compute/docs/startupscript#providing_startup_script_contents_directly
Thank user835611 so much.
I did it.
I encounter another problem when running a complex script: download exe file from link and run it.
My script:
http://hayketnoi.com/abc.exe C: \ abc.exe
C: \ abc.exe
abc.exe is a winform application and I did not have a remote desktop at that time.
Any solution for my case?
I'm doing this well with Vultr's VPS system.

I want to install the system using IPXE in UEFI mode and embed scripts using ipXE.efi.The following:
[root#localhost src]# cat uefi.ipxe
#!ipxe
dhcp
chain http://192.168.222.1/ipxeboot/menu.ipxe
compile:
make bin-x86_64-efi/ipxe.efi EMBED=uefi.ipxe
The installation error is as follows:
enter image description here
I think you need to provide some more context.
I assume you want to load a ipxe script over http on 192.168.222.1. So you have to run a http server on this ip which provides a ipxe script. This ipxe scripts has to provide instructions where to load the os.
I wrote a tutorial to achive this here:

Im trying to learn Hyperledger Composer but seems to be a relatively new technology, i mean there are few tutorials and few solutions to a lot of questions, tutorial does not mention possible error case when following the commands and which means there are is also no solution for those errors.
I have joined the composer channel in their community chat, looks like its running in Discord or something, and asked the same question without a response, i have a better experience here in SO.
This is the problem: I have deployed my business network, installed it, started it, created my network admin card and imported it, then to test if everything is ok i have to command composer network ping --card NAME-OF-MY-ADMIN-CARD
And this error comes:
juan#JuanDeDios:~/proyectos/inovacion/a3-poliza-microservice$ composer network ping --card admin#a3-policy-microservice
Error: transaction returned with failure: AccessException: Participant 'org.hyperledger.composer.system.NetworkAdmin#admin' does not have 'READ' access to resource 'org.hyperledger.composer.system.Network#a3-policy-microservice#0.0.1'
Command failed
I think that it has to do something with the permission.acl file, and gave permission to everyone to everything so there would not be any restrictions to anyone, and tryied again, but failed.
So i thought i had to uninstall my business network and create it again, i deleted my .bna and my network.card files also so everything would be created again, but the same error result.
My other attempt was to update the business network, but didn't work, the same error happened and I'm sure i didn't miss any step from the tutorial. I do also followed the playground tutorial. What i have not done its to create another app with the Yeoman but i will do if i don't find a solution to this problem which would not require me to create another app.
This were my steps:
1-. Created my app with Yeoman
yo hyperledger-composer:businessnetwork
2-. Selected Apache-2.0 for my license
3-. Created a3-policy-microservice as the name of the business network
4-. Created org.microservice.policy (Yeah i switched names but Im totally aware)
5-. Generated my app with a template selecting the NO option
6-. Created my assets, participants and transactions
7-. Changed my permission rules to mine
8-. I generated the .bna file
composer archive create -t dir -n .
9-. Then installed my bna file
composer network install --card PeerAdmin#hlfv1 --archiveFile a3-policy-microservice#0.0.1.bna
10-. Then started my network and created my networkadmin card
composer network start --networkName a3-policy-network --networkVersion 0.0.1 --networkAdmin admin --networkAdminEnrollSecret adminpw --card PeerAdmin#hlfv1 --file networkadmin.card
11-. Imported my card
composer card import --file networkadmin.card
12-. Tried to ping my network
composer network ping --card admin#a3-poliza-microservice
And the error happens
Later i tried to create everything again shutting down my fabric and started it again and creating the network from the first step.
My other attempt was to change the permissions and upgrade my bna network, but it failed too. Im running out of options
Hope this description its not too long to ignore it. Thanks in advance
thanks for the question!
First possibility is that your network name is a3-policy-network but you're pinging a network called a3-poliza-microservice - once you do get the correct ACLs in place (currently, that's the error you're trying to resolve).
The procedure for upgrade would normally be the procedure below:
After your step 12 (where you can't ping the business network due to restrictive ACL conditions, assuming you are using the right network name) you would have:
Make the changes to to include your System ACLs this time eg.
/**
* Sample access control list.
*/
rule SystemACL {
description: "System ACL to permit all access"
participant: "org.hyperledger.composer.system.Participant"
operation: ALL
resource: "org.hyperledger.composer.system.**"
action: ALLOW
}
rule NetworkAdminUser {
description: "Grant business network administrators full access to user resources"
participant: "org.hyperledger.composer.system.NetworkAdmin"
operation: ALL
resource: "**"
action: ALLOW
}
rule NetworkAdminSystem {
description: "Grant business network administrators full access to system resources"
participant: "org.hyperledger.composer.system.NetworkAdmin"
operation: ALL
resource: "org.hyperledger.composer.system.**"
action: ALLOW
}
Update the "version" field in your existing package.json in your Business Network project directory (ie need to change it next increment - eg. update the version property from 0.0.1 to 0.0.2.)
From the same directory, run the following command:
composer archive create --sourceType dir --sourceName . -a a3-policy-network#0.0.2.bna
Now install the new business network code firstly:
composer network install --card PeerAdmin#hlfv1 --archiveFile a3-policy-network#0.0.2.bna
Then perform the requisite upgrade step (single '-' for short form of the parameter):
composer network upgrade -c PeerAdmin#hlfv1 -n a3-policy-network -V 0.0.2
After a few seconds, ping the network again to see ACL changes are now in effect:
composer network ping -c a3-policy-network
I'm trying to setup a private ethereum test network using Puppeth (as Péter Szilágyi demoed in Ethereum devcon three 2017). I'm running it on a macbook pro (macOS Sierra).
When I try to setup the ethstat network component I get an "docker configured incorrectly: bash: docker: command not found" error. I have docker running and I can use it fine in the terminal e.g. docker ps.
Here are the steps I took:
What would you like to do? (default = stats)
1. Show network stats
2. Manage existing genesis
3. Track new remote server
4. Deploy network components
> 4
What would you like to deploy? (recommended order)
1. Ethstats - Network monitoring tool
2. Bootnode - Entry point of the network
3. Sealer - Full node minting new blocks
4. Wallet - Browser wallet for quick sends (todo)
5. Faucet - Crypto faucet to give away funds
6. Dashboard - Website listing above web-services
> 1
Which server do you want to interact with?
1. Connect another server
> 1
Please enter remote server's address:
> localhost

ERROR[11-15|22:47:11] Server not ready for puppeth err="docker configured incorrectly: bash: docker: command not found\n"
Here are my questions:
Is there any documentation / tutorial describing how to setup this remote server properly. Or just on puppeth in general?
Can I not use localhost as "remote server address"
Any ideas on why the docker command is not found (it is installed and running and I can use it ok in the terminal).
Here is what I did.
For the docker you have to use the docker-compose binary. You can find it here.
Furthermore, you have to be sure that an ssh server is running on your localhost and that keys have been generated.
I didn't find any documentations for puppeth whatsoever.
I think I found the root cause to this problem. The SSH daemon is compiled with a default path. If you ssh to a machine with a specific command (other than a shell), you get that default path. This does not include /usr/local/bin for example, where docker lives in my case.
I found the solution here: https://serverfault.com/a/585075:
edit /etc/ssh/sshd_config and make sure it contains PermitUserEnvironment yes (you need to edit this with sudo)
create a file ~/.ssh/environment with the path that you want, in my case:
PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin
When you now run ssh localhost env you should see a PATH that matches whatever you put in ~/.ssh/environment.
I am programatically launching a new instance using the Compute Engine API for Go [1], and a tool I made called vmproxy [2].
The problem I have is that if I launch a preemptible VM using a startup-script-url pointing to https://bitbucket.org/ronoaldo/debian-custom/raw/tip/tools/autobuild, the build script fails to download. I can see in the serial console output that the the startup script metadata is there, and that it attempts to be downloaded with curl, but that part fails.
However, if I reset the instance via the developers console, the script is properly downloaded and runs nicelly.
The code I am using to setup the instance is:
// Ronolinux is a VM Proxy that runs an live systems build on Compute Engine
var (
Ronolinux = &vmproxy.VM{
Path: "/",
Instance: vmproxy.Instance{
Name: "ronolinux-buildd",
Zone: "us-central1-f",
Image: vmproxy.ResourcePrefix + "/debian-cloud/global/images/debian-8-jessie-v20150915",
MachineType: "n1-standard-1",

`,
},
Scopes: []string{ storageReadWrite },

}

If your startup script is not hosted on Cloud Storage, there is a random chance the download will fail. If you look at the serial console output, make sure to scroll horizontally, as it will not wrap long lines. In my case, the error line was very long, and this hidded the real end of the message:
(... long curl on-line progress output )
curl: (7) Failed to connect to bitbucket.org port 443: Connection timed out
(...)
Your host must respond within a 10s timeout. In my case, the first boot usually failed to contact Bitbucket, hence failing to download the script; a VM reset also made things work, as the network latency outside Google Cloud were probably better.
I ended up moving to host the script on cloud storage to avoid these issues.
I am trying to set up a BrowserQuest server that runs in openshift
I've been following this readme. Everything seems to go fine, I get to the end and run rhc app show bq and get the following output:

My questions are what is going wrong and how can I fix it? Many thanks for your consideration in reading through this and any suggestions you might have for resolving it
You need to access http://bq-plantagenet.rhcloud.com, leave off the port 8080, that is the port you listen on internally. You should also try checking your log files (https://developers.openshift.com/en/managing-log-files.html) to see what errors your application is producing.
