Raspberry - can't clone from bitbucket using SSH - ssh

Didn't thought I will be stuck here.
Got .ssh key on my win machine: [my user]/.ssh/mybitbucket
Able to clone from bitbucket.org with it
Need to clone project to RaspberryPi
Copy-pasted mybitbucket and mybitbucket.pub to ~/.ssh on Raspberry
Then git clone git#bitbucket.org:[username]/my_utils.git
and got this:
Failed to add the host to the list of known hosts
(/home/pi/.ssh/known_hosts).
Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
Any help?
Also added mybitbucket.pub to authorized_keys, but can't connect to Raspberry from Xshell with SSH key for reason unknown to me. Just choosing my key from options, click OK, the connection window blinks and nothing happens
EDIT:
Just for an experiment I generated a new key on Raspberry and added it to bitbucket - that worked. Though how to add existing keys?

Failed to add the host to the list of known hosts
Also added mybitbucket.pub to authorized_keys, but can't connect to Raspberry
I am 98% sure both problems are the result of one misconfiguration: files in /home/pi/.ssh belong to user root. To fix:
sudo chown -R pi /home/pi/.ssh
chmod -R u=rw,go= /home/pi/.ssh
After that copy relevant parts of [my user]/.ssh/config to /home/pi/.ssh/config.

SSH to Github not working

SSH has been working fine for the last few weeks since I got my new PC. I've had no problems but today I started getting:
ssh: connect to host github.com port 22: resource temporarily unavailable
I did some googling and found that there is a common issue with WSL which sometimes causes this, but I'm unable to SSH from my bash shell, or from cmd/powershell.
This is the part that confuses me, if I do: ssh -T git#192.30.253.113 I am prompted for the password to my key, it successfully authenticates and responds with "Hi alexmk92! You've successfully authenticated".
Great, that at least proves that my firewall isn't blocking SSH on port 22. But why does git#github.com throw the resource failed error? My initial thought is that this could be a DNS problem.
So I tried to configure my network adapter to use Google's DNS server (8.8.8.8 and 8.8.4.4) I even configured the IPV6 DNS servers just in case. Following this I did an ipconfig /flushdns, attempted to connect via git#github.com again and BAM the same result, however git#192.30.253.113 still works.
I'm guessing another potential cause is that github.com is behind a load balancer and one of the IP's on the cluster could be black-listed somewhere on my machine? I'm just pulling guesses out of thin air now, any help would be greatly appreciated, this is driving me insane.
After some further Googling it turned out that my machine did not have a hosts entry for github.com and it was unable to automatically resolve it.
In Windows Subsystem for Linux I created a ssh config file
touch ~/.ssh/config
(for some reason the base distro of Ubuntu 18.04 on the windows marketplace didn't have one) I then had to make sure the file permissions were correct:
chmod 755 ~/.ssh/config
Once the file was created, I edited it with
sudo nano ~/.ssh/config
and added github.com as a Host.
Host github.com
Hostname ssh.github.com
Port 22
Upon saving, I ran
sudo /etc/init.d/ssh restart
and attempted
ssh -T git#github.com
Everything now seems to be working.
In my case my ISP did not allow ssh, so it was not working from cmd and wsl both. Got around it using vpn
To have successful SSH connection to Github, SSH key has to be import into Github
Open Git bash or Terminal
Run the command ssh-keygen
Choose all default option
A private and a public key gets generated in the folder * < user_home>/.ssh/*
Login to Github.com
Navigate to account settings
Choose item "SSH and GPG Keys" from the side navigation bar
click added new SSh key
Copy and save public key content from * < user_home>/.ssh/id_rsa.pub *

Private key to connect to the machine via SSH must be owned by the user running Vagrant

I am trying to follow this vagrant tutorial. I get error after my first two command. I wrote these two command from command line
$ vagrant init hashicorp/precise64
$ vagrant up
After I ran vagrant up command I get this message.
The private key to connect to the machine via SSH must be owned
by the user running Vagrant. This is a strict requirement from
SSH itself. Please fix the following key to be owned by the user
running Vagrant:
/media/bcc/Other/Linux/vagrant3/.vagrant/machines/default/virtualbox/private_key
And then if I run any command I get the same error. Even if I run vagrant ssh I get the same error message. Please help me to fix the problem.
I am on linux mint and using virutal box as well.
Exactly as the error message tells you:
The private key to connect to the machine via SSH must be owned
by the user running Vagrant.
Therefore check permissions of file using
stat /media/bcc/Other/Linux/vagrant3/.vagrant/machines/default/virtualbox/private_key
check what user you are running using
id
or
whoami
and then modify owner of the file:
chown `whoami` /media/bcc/Other/Linux/vagrant3/.vagrant/machines/default/virtualbox/private_key
Note that this might not be possible if your /media/bbc/ is some non-linux filesystem that does not support linux permissions. In that case you should choose more suitable location for you private key.
Jakuje has the correct answer - if the file system you are working on supports changing the owner.
If you are trying to mount the vagrant box off of NTFS, it is not possible to change the owner of the key file.
If you want to mount the file on NTFS and you are running a local instance you can try the following which worked for me:
Vagrant Halt
[remove the vagrant box]
[Add the following line to Vagrantfile]
config.ssh.insert_key=false
[** you may need to remove and clone your project again]
Vagrant Provision
This solution may not be suitable for a live instance - it uses the default insecure ssh key. If you require more security you might be able to find a more palatable soultion here https://www.vagrantup.com/docs/vagrantfile/ssh_settings.html
If you put vagrant data on NTFS you can use this trick to bypass the keyfile ownership/permissions check.
Copy your key file to $HOME/.ssh/ or where-ever on a suitable filesystem where you can set it to the correct ownership and permissions. Then simply create a symlink (!) to it inside the NTFS directory (where you have set $VAGRANT_HOME, for example) like this:
ln -sr $HOME/.ssh/your_key_file your_key_file

Cannot ssh into server except with google dev console ssh

I cannot ssh from my computer into the server hosted on Google Cloud.
I tried the normal ssh-keygen with user#domain.com and uploading the public key, which worked last time, but this time it didn't. The issue started after I changed the password for the account. After that I could no longer ssh or sftp into the account, although I wasn't disconnected until I disconnected.
I then tried the gcloud ssh user#instance and it ran fine and told me it just hasn't propagated yet.
I added AllowUsers user to the server's ssh config file and I restarted ssh on the server, but still the same result
Here's the error:
Permission denied (publickey).
ERROR: (gcloud.compute.ssh) [/usr/bin/ssh] exited with return code [255].
Update:
I've been working with Google tech support and this issue is still unresolvable. A file called authorized_keys permissions keep getting changed on boot to another user, who I also cannot log in as.
So I change it to:
thisUser:www-data 755
but on boot it changes it to:
otherUser:otherUser 600
There are a couple of things in order to fix this. You can take advantage of the metadata feature in GCE and add a startup script that would automatically change the permissions.
From the developers console, go to your Instance > Metadata and add a pair of Key/value
key : startup-script
value: chmod 755 /home/your_user/.ssh/authorized_keys OR chmod 755 ~/.ssh
after rebooting you should check the Serial Ouput option further down that page and see if it ran on startup. it should show you something along these lines :
startup script found in metadata.
startupscript: Running startup script /var/run/google.startup.script
Further information can be found HERE
Hope that helps!
I solved this by deleting the existing ssh key under Custom metadata in the VM settings. I then could login on ssh

ssh -T git#github.com Permission denied (publickey)

I tried to push my blog (Octopress) to github and got this error:
MacBook-Air:octopress bdeely$ git push origin source
Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
I generated an SSH key, saved it, and even linked it with my GitHub account in the SSH key settings, but I went ahead and checked the status and got the same error:
MacBook-Air:.ssh bdeely$ ssh -T git#github.com
Permission denied (publickey).
In addition to this, I checked github's help page, did the following and got this error message:
MacBook-Air:~ bdeely$ ssh-add -l
The agent has no identities.
Does anyone know what is wrong and how I can fix this?
On OSX, if you type
ssh-add -l
and you get back "no identities", that means your ssh agent does not have any identities loaded into it. Oftentimes, when the mac reboots, you have no identities.
I add mine back after a re-boot by explicitly running
ssh-add
This loads a default identity from ~/.ssh/id_rsa
You can also use the ssh-add command with a specific identity
ssh-add ~/foo/bar/is_rsa
After you add your identies, you can seem them all listed by typing
ssh-add -l
Make sure you have at least one listed.
Follow the commands:
mkdir ~/.ssh //in case that the folder doesnt exist...
cd ~/.ssh
ssh-keygen -t rsa -C "youremail#somewhere.gr"
#hit enter when asks for file to save the key.
#enter the passphrase
At last copy the id_rsa.pub into your github account.
Try this in your terminal:
eval `ssh-agent -s`
ssh-add ~/.ssh/id_rsa
enter your passphrase if any and it should work. Hope this helps :-)
I hope this helps you:
I was having the identical problem and about to take my own eyes out with insane frustration; nothing online led me to an answer and I was trying to use the git push command without specifying the URL exactly (which could also solve the problem I believe), so I didn't see how the connection was failing.
I had set up my .ssh/config correctly for two users with two different keys, even using IdentitiesOnly yes which is supposed to override ssh-agent that was automatically supplying the WRONG ssh identity.
I finally realized the problem as I examined the local repository configuration - it was the entry
[remote "origin"]
url = git#github.com:{my-username}/{my-repo-name}.git
My configuration in .ssh/config file was using the same HostName github.com entry for both users and I'm completely new to all this so I didn't realize that to correctly override ssh-agent, I had to specify the exact URL or else the specific identities in my .ssh/config file would be ignored and the first key that ssy-agent listed (which was the wrong one my my case) would be used by default.
I fixed this by changing the local repo URL to url = git#github-personal:{my-username}/{my-repo-name}.git, where I had set Host github-personal as the identity in my .ssh/config.
Another way to solve this would be specifying the user in the URL in the git push command itself, or even better, a solution described here in a post AFTER solving this my own crappy way:
https://superuser.com/questions/272465/using-multiple-ssh-public-keys
I can't believe that no official source could offer a solution for or even properly explain this edge-case that seems really common (accessing two different github accounts from one machine with SSL).
I experienced the same problem. The reason was that I moved the key-files to another folder; it worked successfully when I moved them back to where they were originally.

Git, vagrant (lucid 32), mountain lion, Permission denied

I'm having a similar problem to this:
Permission denied (publickey). fatal: The remote end hung up unexpectedly while pushing back to git repository
But I suspect it might be more complicated because I am running vagrant on a mac (mountain lion) and I am having this "Permission Denied" issue that I wasn't having in Snow Leopard.
I set up git on my mac (mountain lion) with ssh key, it works.
I set up vagrant (lucid32 box) and set up a new ssh key (once I ssh'ed into vagrant):
cd ~/.ssh
ssh-keygen -t rsa -C "myemail#mail.com"
Generating public/private rsa key pair.
Enter file in which to save the key (/home/vagrant/.ssh/id_rsa):
Enter passphrase (empty for no passphrase): [just hit enter]
Enter same passphrase again: [just hit enter]
Then I added the ssh key to my github repo (note: was having problems with pbcopy/xclip so I just used vi and copy-pasted)
vagrant#lucid32:~$ cd /vagrant/
vagrant#lucid32:/vagrant$ git push -u origin master
Permission denied (publickey).
fatal: The remote end hung up unexpectedly
So, now I have two ssh keys in my github repo:
- My Mac key (works, can commit to my non-vagrant repo from my mac)
- My vagrant key (does not work, cannot ssh into vagrant and commit my repo from my vagrant box)
Are you trying to push to a github repo?
If so, you're going to need to add the SSH key of the vagrant VM to your account on Github under account settings.
Keep in mind, a Vagrant VM is essentially a "different" machine than your local machine, so it will have a different SSH key.
See this github article on working with SSH keys
Mine started working, I followed this advice:
Unable to Git-push master to Github
And added a config file to my ~/.ssh folder. Not it works but I'm not sure if why that helps?
