Re: Need help - build "Execute Shell"

2020-07-29 Thread jeremy mordkoff 
Normally a SSH keypair is created on the client (in your case the jenkins 
server) and then the public key is copied to the server. This is more 
secure because the private key is created on the client and is never copied 
anywhere else. 

This level of security is rarely needed or enforced in a lab, but it is a 
good habit anyway. 

Make sure the keys you use for jenkins do not have a pass-phrase.

This doing something completly different, you  are creating a jenkins agent 
via ssh,  what you need is an ssh-agent. 

I assume you are using pipelines, the wrap the ssh-calling sh step in an 
sshagent wrapper (best to use the Snippet generator for the details).

Fine again ( at least if ~ expand to the correct user (whatever jenkins is 
running the agent as), unless you also explicitly specify the user in your 
ssh requests.  From the log it looks like
the agent is running as root (no a good idea, but that is another thing), 
so you would need to add the key to /root/.ssh/authorized_keys (and 
possibly allow remote root logins in the sshd config).

Re: Need help - build "Execute Shell"

2020-07-29 Thread sakshira...@gmail.com 
and how it worked for you:  ssh password less connection works fine (using 
rsa public key). i followed below steps to do this: i followed below steps 
to resolve it till now but didnt work:
   
   - 
   
   Create an SSH key pair (public/private) Ran the command “ssh-keygen -t 
   rsa -C "Jenkins agent key" -f "jenkinsAgent_rsa" “
   - 
   
   Create an SSH credential in the Jenkins machine and put the private key 
   there Created the credentials and put jenkinsAgent_rsa into it.
   - 
   
   Create an SSH agent see 
   
https://github.com/jenkinsci/ssh-slaves-plugin/blob/master/doc/CONFIGURE.md#configure-launch-agents-via-ssh
 – 
   This is creating a node which I didn’t do before – so I created the node 
   and selected the credential with the private key. The verification strategy 
   slect is non-verifying.
   - 
  
  Select the SSH credential created before as credentials
  - 
  
  Chose the verification strategy that you want, see the documentation, 
  if you have problems start with the "Non verifying Verification Strategy" 
  you can change it later
  - 
   
   Add the public key on ~/.ssh/authorized_keys This was done
   
but i am not able to establish the connection between jenkins and ssh server
my ssh and jenkins server both are hosted on same ip

Re: Need help - build "Execute Shell"

2020-07-20 Thread Sakshi Rathore 
I am also facing same kind of issue :

0


I have a absh script which connects and exexutes programs from my local to 
remote server and now this should be executed from jenkins build so for 
this jenkins is taking continous changes from git for this script but my 
build is failing with below error:

Warning: Identity file 
/c/Users/D35N/Downloads/GitHubProjeckt/Automation/GitHubProjeckt/newharbortestkey
 
not accessible: No such file or directory. Host key verification failed. 
Build step 'Execute shell' marked build as failure

I have tried to set ssh connectivity in my jenkins server for this remote 
server ,credentials and ssh plugins but using my key i am getting an error 
cant connect to the server.

when i run the script from local it works fine and my ssh connection gets 
established properly using SSH key.

jenkins server is also integrated or installed on my kuberenets cluster 
which is my remote server in this case and bash script should execute on 
this kuberenets cluster.

Need help - build "Execute Shell"

2020-07-16 Thread Shrikant Nayak 
Jenkins ver. 2.190.3  on RHEL-7.7

Hello Jenkins Gurus / Users,
Has anyone come across similar issues as me & resolved? 
ssh password less connection works fine (using rsa public key).
my shell script works fine if I run from command prompt in Jenkins system; 
However the same script fails through Jenkins job. Please see part of the 
console output for the error; the job is successful, but it does not copy 
intended file to the remote host.
