I am trying to install ipfs using the following command from this link
enter link description here
curl -O https://dist.ipfs.io/go-ipfs/v0.9.1/go-ipfs_v0.9.1_darwin-arm64.tar.gz
but every time when I run it on terminal gives me this error
curl: (28) Failed to connect to dist.ipfs.io port 443: Operation timed
out

I followed this tutorial to connect qmp-shell to a QEMU VM instance.
1. Start QMP on a unix socket
# qemu-system-aarch64 -M virt -qmp unix:./qmp-sock,server,wait=off
2. Run the script
# qmp-shell ./qmp-sock
3. You should get the following prompt
(QEMU)
But step 2 gives below error:
ERROR: Couldn't connect to ./qmp-sock: Failed to establish connection: [Errno 2] No such file or directory
What could be wrong?
I am trying to setup KVM, but when running $ sudo virsh net-define br10.xml I get this:
error: failed to connect to the hypervisor
error: Failed to connect socket to '/var/run/libvirt/libvirt-sock': No such file or directory
And when jumping into virt-manager GUI a get this dialog Unable to connect to libvirt qemu:///system.
I checked if I am in both kvm and libvirt groups and that seems okay.
I also checked if the libvrt-sock file is created when running $ sudo systemctl start libvirtd.service but there is nothing.
So it showed up that privilges for my files wasn't set correctly. Now everything works
Here is my startup script:
#! /bin/sh
sudo apt-get update
sudo apt-get install mysql-client
wget https://dl.google.com/cloudsql/cloud_sql_proxy.linux.amd64 -O cloud_sql_proxy
chmod +x cloud_sql_proxy
sudo mkdir /cloudsql; sudo chmod 777 /cloudsql
./cloud_sql_proxy -dir=/cloudsql --instances=a:us-east4:b &
Here is the error I get:
Feb 19 22:12:38 instance-group-1-th2f startup-script: INFO startup-
script: 2019/02/19 22:12:38 errors parsing config:

Feb 19 22:12:38 instance-group-1-th2f startup-script: INFO startup-script: 2019/02/19 22:12:38 Ready for new connections
If I open the instance manually and run the following, it will work:
./cloud_sql_proxy -dir=/cloudsql -instances=a:us-east4:b &
I am guessing that it is an authentication problem, but based on this:
Note: If your Compute Engine instance has either the Full API access
or Cloud SQL API scope, you can skip this step; you do not need to
provide a certificate file when you start the proxy.
It shouldn't have any problems since mine has a Full API access
I have a second gen instance and the Cloud SQL Admin API is enabled.
dial tcp: lookup www.googleapis.com on [::1]:53: read udp [::1]:52058->[::1]:53: read: connection refused
It doesn't look like your issue is authenticated related, but instead you are unable to either lookup or reach www.googleapis.com. Do you have a firewall that might be blocking the outgoing connection?
I have setup Hyperledger Sawtooth on Docker,
I am trying to test sawtooth XO transactions with following commands
uname#uname:~/sawtooth$ docker exec -it sawtooth-shell-default bash
root#5279e5a413c1:/# xo create one
but I am getting following error
Error: Failed to connect to http://127.0.0.1:8008/batches: HTTPConnectionPool(host='127.0.0.1', port=8008): Max retries exceeded with url: /batches (Caused by NewConnectionError(': Failed to establish a new connection: [Errno 111] Connection refused',))
FYKI This commands works for me
From shell this gives me blocks
curl http://rest-api:8008/blocks
From my host this works as expected
curl http://localhost:8008/blocks
curl http://127.0.0.1:8008/blocks
What is wrong with this?
My yaml file is the default one, you can find it here
If you are using docker you have to mention url to APIs this way
xo create one --url http://rest-api:8008
I found this after Ashish gave this hint at
https://chat.hyperledger.org/channel/sawtooth
I am getting the error message
error: operation failed: Failed to connect to remote libvirt URI qemu+ssh://mytargethostname.mydomain.com/system: Cannot recv data: Host key verification failed.: Connection reset by peer
when I try to run the kvm migration command like this
virsh migrate --verbose --live --p2p --tunnelled hosttomigrate qemu+ssh://mytargethostname.mydomain.com/system
I can successfully view the running vms on the target host when I run
virsh -c qemu+ssh://mytargethostname.mydomain.com/system list --all
Is there some special configuration that I may need for kvm ?
