Hi while trying to inint my nodes within a elevated powershell i constantly gives the following error after i created the network,and the master en 3 nodes @master: Permission denied (publickey,gssapi-keyex,gssapi-with-mic)
waiting for master to init...
key_load_public: invalid format
What can i do to get it ti init and get the cluster up ad running
I am running on Windows 10 pro with hyper-v installed the nodes and master are running as far is i can see within the hyper-v manager
I was trying to use hyperctl but is unable to ssh to the system. I always get ssh_exchange_identification: Connection closed by remote host. Nor am I able to login to the VM manually. I removed the public access to the entire user's folder and am running the PowerShell in admin mode.
OS Name: Microsoft Windows 10 Enterprise
OS Version: 10.0.18363 N/A Build 18363
But it keeps dooing this
Enter passphrase for key 'C:\Users\user/.ssh/id_rsa':

HI i have seached this over and over but all the linux based things wont work.
even when trying to ssh into one of node r the master it will kick
PS C:\Users\w510> ssh master
The authenticity of host 'master (10.10.0.10)' can't be established.
ECDSA key fingerprint is SHA256:kTH3kmEtq7qfXZKBv2XHihTcGAVoi2CG3njS/FQjMXY.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'master,10.10.0.10' (ECDSA) to the list of known hosts.
w510@master: Permission denied (publickey,gssapi-keyex,gssapi-with-mic).
ran ssh-keygen and it generated 2 files in .ssh without password
but it keeps dooing this.
keep in mind i am not running linux , its a windows host.
