I'm trying to configure flow which include git repository
things to note:
i have a git server running in internal network
my jenkin running on one of the machine in the network so it can access git server through local ip
normally i would go like this with my git command
git remote add origin ssh://username#git-server-ip/path-to-folder
after that it prompt me to type in the password for the above username
and i can work on the git repo like normal
The problems:
in Jenkin i already set up credential with "username and password" type
When i paste in the ssh url into the Repository URL, it take a while and return error:
Failed to connect to repository ...
stdout: stderr: Permission denied, please try again. Permission
denied, please try again. username#git-server-ip: Permission denied
(publickey, password). fatal: Could not read from remote repository.
Please make sure you have the correct access rights and the repository
exists.
i had selected credentials and double check username and password it's correct. i tried running the ls-remote command manually in the terminal
git ls-remote -h -- ssh://username#git-server-ip/path-to-folder HEAD
it prompts to input the password, i typed it in and it run normal without error
Why is the error only happens on Jenkins when i input the repo ssh url? is username and password credential the wrong approach for credential? what else should i use?
there no guide online for Jenkin with internal git ssh url as i known of
the closest i can see my problem related to is this question Jenkins Git ssh setup does not let me use username/password , but it doesn't have an accepted answer yet, and the answer suggest going with "ssh username and private key"
when I am trying to clone a rails app repo I have got permission to, I am getting this issue.
Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
Even after adding public key by generating one, I am unable to solve this.
Although I am able to clone using he https method but after making changes, the same error comes while I try to push the code.
Please suggest an answer for this.
First, cd into your .ssh directory. Open up the terminal and run:
cd ~/.ssh && ssh-keygen
Second, you need to copy this to your clipboard:
cat id_rsa.pub | pbcopy # On OSX
cat id_rsa.pub | xclip # On Linux
Third, add your newly generated ssh key to your account via the github/bitbucket website (just paste there).
Next, setup your git config:
git config --global user.name 'your_user_name'
git config --global user.email 'your_email'
Finally, restart your command line to make sure the config is reloaded.
Now, you should be able to clone and push from/to your github repository.
For more information on this, see this github page or this bitbucket page.
When attempting to clone, push, or pull over SSH with Git, you may receive one of these messages if Bitbucket couldn't authenticate with the keys that your SSH agent offered.
Here are the most common reasons why you may see these messages:
You used sudo when attempting the connection
You shouldn't use sudo when cloning, pushing, or pulling because the ssh-agent runs on the user level, not the root level.
Your public key isn't loaded into Bitbucket
To check if your public key is loaded into Bitbucket, do the following:
From Bitbucket, choose Personal settings from your avatar in the lower left.
The Account settings page displays.
Click SSH keys.
The SSH keys page shows a list of any existing keys.
If you don't have any keys listed, you can follow our Set up an SSH key documentation to set one up.
Your key isn't loaded into your SSH agent
If your SSH agent doesn't know to offer Bitbucket a key, the connection fails. You may run into this issue if you've recently restarted your system.
You can refer to this Article for more informations:
https://support.atlassian.com/bitbucket-cloud/docs/troubleshoot-ssh-issues/
Check few things.
Is the generated new key is the one your ssh agent using when trying to ssh to server.
(Your ssh agent might be using a different key than the one you generated)
use this to list currently loaded keys by agent.
ssh-add -L
You properly added public key to your repository hosting location.
The keys corresponding to above 1 and 2 should match.
Please see this article: GitHub: Generating SSH Keys. What happens when you run:
ssh -T git#bitbucket.org
?
You may have added the wrong key to authenticate with.
I faced this error when I created another repository in my local. My ssh-keys were already set up and I was trying to push code through vs code.
The issue got resolved when I git push-ed through git bash like I was doing before.
For bit bucket I think I have tried everything with ssh. I have tried the answer from this stackoverflow question as well. But it doesn't work. So finally I just changed the clone command from SSH to HTTPS and it worked. Only then it asked for password for my account.
I have installed GitLab. Suppose I installed it in /home/myuser/gitlab.
I created a new project
I was told to create a repo "test" I put in /home/myuser/gitlab/test
I added some SSH key in /home/myuser/.ssh
Then I initialized a Git repo in /home/myuser/gitlab/test.
Following instructions, I added a remote git#localhost:root/testing.git
but when I try to push, I get this error message:
$ git push -u origin master
ssh: connect to host localhost port 22: Connection refused
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
I installed GitLab in OS X and I have other SSH keys in /home/myhome/.ssh, I have set up the user email and name inside /home/myuser/gitlab/.git/config, (and set those globally just for testing) and the server is launched from /home/myuser/gitlab. Does anybody have an idea where this error comes from?
If I run ssh git#localhost, I get
/home/myhome/.ssh/config line 4: garbage at end of line; "home".
where in this file I have some settings for a remote server for another project. I think it is the problem but I don't really know how to fix it.
Update : Here's the content of my ~/.git/config file
Host remote_test_server
Hostname remote_test_user#ftp.remote_test_server
IdentityFile ~/.ssh/id_rsa_stf.pub
User <your home acct>
/home/myhome/.ssh/config line 4: garbage at end of line; "home".
That would prevent any ssh command to properly function, because of a parasite echo done by the remote session.
Check your .profile or other .rc files, and see if any echo is done in those.
Or at least, test with ssh -T git#localhost, in order to disable any TTY allocation.
check also the content of your .ssh/config file, which doesn't seem to be properly formatted.
See this example of a config file:
User should be the login name of the account used for the ssh session on the rmeote server.
It should not be the homedir path.
IdentityFile should reference the private key (~/.ssh/id_rsa_stf), not the public one!
Hostname should reference the remote server 'ftp.remote_test_server', not the user#remoteServer.
I have a problem with jenkins, setting "git", shows the following error:
Failed to connect to repository : Command "git ls-remote -h https://person#bitbucket.org/person/projectmarket.git HEAD" returned status code 128:
stdout:
stderr: fatal: Authentication failed
I have tested with ssh:
git#bitbucket.org:person/projectmarket.git
This is error:
Failed to connect to repository : Command "git ls-remote -h git#bitbucket.org:person/projectmarket.git HEAD" returned status code 128:
stdout:
stderr: Host key verification failed.
fatal: The remote end hung up unexpectedly
I've also done these steps with "SSH key".
Login under Jenkins
sudo su jenkins
Copy your github key to Jenkins .ssh folder
cp ~/.ssh/id_rsa_github* /var/lib/jenkins/.ssh/
Rename the keys
mv id_rsa_github id_rsa
mv id_rsa_github.pub id_rsa.pub
but still not working git repository in jenkins.
thanks by help!.
Change to the jenkins user and run the command manually:
git ls-remote -h git#bitbucket.org:person/projectmarket.git HEAD
You will get the standard SSH warning when first connecting to a new host via SSH:
The authenticity of host 'bitbucket.org (207.223.240.181)' can't be established.
RSA key fingerprint is 97:8c:1b:f2:6f:14:6b:5c:3b:ec:aa:46:46:74:7c:40.
Are you sure you want to continue connecting (yes/no)?
Type yes and press Enter. The host key for bitbucket.org will now be added to the ~/.ssh/known_hosts file and you won't get this error in Jenkins anymore.
Jenkins is a service account, it doesn't have a shell by design. It is generally accepted that service accounts. shouldn't be able to log in interactively.
To resolve "Jenkins Host key verification failed", do the following steps. I have used mercurial with jenkins.
1)Execute following commands on terminal
$ sudo su -s /bin/bash jenkins
provide password
2)Generate public private key using the following command:
ssh-keygen
you can see output as ::
Generating public/private rsa key pair.
Enter file in which to save the key (/var/lib/jenkins/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
3)Press Enter --> Do not give any passphrase--> press enter
Key has been generated
4) go to --> cat /var/lib/jenkins/.ssh/id_rsa.pub
5) Copy key from id_rsa.pub
6)Exit from bash
7) ssh#yourrepository
8) vi .ssh/authorized_keys
9) Paste the key
10) exit
11)Manually login to mercurial server
Note: Pls do manually login otherwise jenkins will again give error "host verification failed"
12)once manually done, Now go to Jenkins and give build
Enjoy!!!
Good Luck
Or you can use:
ssh -oStrictHostKeyChecking=no host
This will be insecure (man in the middle attacks) but easiest solution.
The better way to do that is to generate correct mappings between host and ip address, so ssh will not complain:
#!/bin/bash
for domain in "github.com" "bitbucket.org"; do
sed -i "/$domain/d" ~/.ssh/known_hosts
line=$(ssh-keyscan $domain,`nslookup $domain | awk '/^Address: / { print $2 ; exit }'`)
echo $line >> ~/.ssh/known_hosts
done
Excerpt from gist.
I think, that many people didnt recognize, at least available since jenkins 2.361:
btw. No Verification is for sure not the best option.
Had same problem, i fix it like that :
reset permission on id_rsa* only for current user no group no other
chmod o-rwx ~/.ssh/id*
chmod G-rwx ~/.ssh/id*
ls -lart ~/.ssh/
-rw------- 1 jenkins nogroup 398 avril 3 09:34 id_rsa.pub
-rw------- 1 jenkins nogroup 1675 avril 3 09:34 id_rsa
And clear ~/.ssh/know_hosts
Now Connect as jenkins
sudo su jenkins
Try the jenkins commands
git ls-remote -h git#bitbucket.org:user/project.git HEAD
If no problem appears, now jenkins will be able to connect the repo (for me ^^ at least)
As for the workaround (e.g. Windows slave), define the following environment variable in global properties:
GIT_SSH_COMMAND="ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no"
Note: If you don't see the option, you probably need EnvInject plugin for it.
login as jenkins using: "sudo su -s /bin/bash jenkins"
git clone the desired repo which causes the key error
it will ask you to add the key by showing Yes/No (enter yes or y)
that's it!
you can now re-run the jenkins job.
I hope you this will fix your issue.
using https://bitbucket.org/YYYY/XX.git
you shoud delete username#
Make sure we are not editing any of the default sshd_config properties to skip the error
Host Verification Failed - Definitely a missing entry of hostname in known_hosts file
Login to the server where the process is failing and do the following:
Sudo to the user running the process
ssh-copy-id destinationuser#destinationhostname
It will prompt like this for the first time, say yes and it will also ask password for the first time:
The authenticity of host 'sample.org (205.214.640.91)' can't be established.
RSA key fingerprint is 97:8c:1b:f2:6f:14:6b:5c:3b:ec:aa:46:46:74:7c:40.
Are you sure you want to continue connecting (yes/no)? *yes*
Password prompt ? give password
Now from the server where process is running, do ssh destinationuser#destinationhostname. It should login without a password.
Note: Do not change the default permissions of files in the user's .ssh directory, you will end up with different issues
I ran into this issue and it turned out the problem was that the jenkins service wasn't being run as the jenkins user. So running the commands as the jenkins user worked just fine.
Copy host keys from both bitbucket and github:
ssh root#deployserver 'echo "$(ssh-keyscan -t rsa,dsa bitbucket.org)" >> /root/.ssh/known_hosts'
ssh root#deployserver 'echo "$(ssh-keyscan -t rsa,dsa github.com)" >> /root/.ssh/known_hosts'
Best way you can just use your "git url" in 'https" URL format in the Jenkinsfile or wherever you want.
git url: 'https://github.com/jglick/simple-maven-project-with-tests.git'
SSH
If you are trying it with SSH, then the Host key Verification error can come due to several reasons.Follow these steps to overcome all the reasons.
Set the Environment variable as HOME and provide the address as the root directory of .ssh folder. e.g:- If your .ssh is kept inside Name folder.
C:/Users/Name.
Now make sure that the public SSH key is being provided in the repository link also. Either it is github or bitbucket or any other.
Open git bash. And try cloning the project from the repository. This will help in adding your repository URL in the known_host file, which is being auto created in the .ssh folder.
Now open jenkins and create a new job. Then click on configure.
provide the cloning URL in Source code management under Git. The URL should be start with git#github.com/......... or ssh://proje........
Under the Credential you need to add the username and password of your repository form which you are cloning the project. Select that credential.
And now apply and save the configuration.
Bingo! Start building the project. I hope now you will not get any Host Key verification error!
Try
ssh-keygen -R hostname
-R hostname Removes all keys belonging to hostname from a known_hosts file. This option is useful to delete hashed hosts
Use ssh-keyscan should be much more easier:
ssh-keyscan bitbucket.org >> ~/.ssh/known_hosts
This command will put all required hosts to ~/.ssh/known_hosts. You will need to run this command inside your Jenkins machine. You can also create a job and put that command into the "Execute shell" section of the Configure of that job and then execute the job.
issue is with the /var/lib/jenkins/.ssh/known_hosts. It exists in the first case, but not in the second one. This means you are running either on different system or the second case is somehow jailed in chroot or by other means separated from the rest of the filesystem (this is a good idea for running random code from jenkins).
Next steps are finding out how are the chroots for this user created and modify the known hosts inside this chroot. Or just go other ways of ignoring known hosts, such as ssh-keyscan, StrictHostKeyChecking=no or so.
After ssh-keygen probably one only needs to copy the public key to remote host with:
ssh-copy-id -i ~/.ssh/mykey user#host
There is a safe and (relative easy) way to accomplish this, which should also work if you have separate worker nodes/clouds (like docker/kubernetes).
Adding host keys to Jenkins configuration
First go to a console and execute ssh-keyscan your_git_server.url
Copy the output of that command
Then navigate to https://YOUR_JENKINS_URL/manage/configureSecurity/
Scroll down to Git Host Key Verification Configuration
Paste the output of the command into the window. it should look like this:
Both bitbucket and github have pages about their keys and servers. Read them and ensure that you are adding the proper keys and not some random keys
Getting the ssh-keyscan via your Jenkins installation
If you for some reason do not have ssh-keyscan, you can go to the script console ( https://YOUR_JENKINS_URL/manage/script ) and paste in the following script:
def sout = new StringBuilder(), serr = new StringBuilder()
def proc = 'ssh-keyscan bitbucket.org'.execute()
proc.consumeProcessOutput(sout, serr)
proc.waitForOrKill(1000)
println "copy this to jenkins>\n$sout"
//println "err> $serr"
I have been trying to set up a staging machine to run project at home (rails application).
# Remote machine connection
REPLOGIN=joel
REPADDRESS=192.168.2.100
REPLOCATION=/Users/joel/Projects/bio_watts #Repo location
REPNAME=biowatts
# Copy the repo to the server
echo "Copying the git repo to the server $REPADDRESS"
echo "repname:$REPNAME"
TEMPREP="$REPNAME.git"
echo "$TEMPREP"
git clone --bare .git $TEMPREP
scp -r $TEMPREP $REPLOGIN#$REPADDRESS:$REPLOCATION/
# Set up the origin for the project
#echo "Linking current repository to remote repository"
git remote add imac $REPLOGIN#$REPADDRESS:$REPLOCATION/$REPNAME.git/
All this worked fine
$git remote
imac <== this is my remote machine
When I try to git push to this machine I get:
Permission denied (publickey,keyboard-interactive).
fatal: The remote end hung up unexpectedly
I know there is something about SSH ... but I don't understand what I need to do on my local and on my remote machines (Mac OS X Lion).
Can someone help?
Cheers,
Joel
NEXT QUESTION:
On my remote machine I do find my cloned biowatts.git file ... but I don't see the project files (rails app) ... how does it work?
My intent is to git push to my imac and run my app there (thin start) ???
Do I need to copy my file manually? I assumed that the git clone would copy every I needed ...
Your remote git server should know your machine via your iMac's public ssh key and should have a config somewhere allowing you to push (write rights).
That remote machine needs to know about your ssh keys.
You need to generate a key locally (if you don't have one) and then add the public key to the remote server's ~/.ssh/authorized_keys
You can follow the GitHub tutorial on setting up keys (if you don't already have them set up).
http://help.github.com/mac-set-up-git/
Instead of Step 4. Add your SSH key to GitHub, you'll need to add your key to the authorized_keys file on the server.
In the future, for those of you encountering this in assembla specifically, the solution is to copy your ~/.ssh/id_rsa.pub to the assembla profile. This post gives step by step instructions.
