Error using scp to transfer files to CentOS

Thiago Carvalho Davila
Hello,

I'm having trouble to transfer files via scp to my CentOS servers. I generated RSA keys on destination servers:

ssh-keygen -t rsa

And added to known_hosts in my jenkins slave:

ssh-keyscan -t rsa ${HOST_IP} >> ~/.ssh/known_hosts

Then I made a job to transfer files and I am getting the error:
+ scp /opt/programas/jenkins/tmp/file.jar root@10.139.5.166:/opt/websites/jboss/6.3-eap/file.jar
Permission denied, please try again.
Permission denied, please try again.
Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).
lost connection

Any thoughts?

Best regards,

Thiago

So now the slave knows your destination server, that's good.

But obviously, the root user at the destination server doesn't know your jenkins user. You need to provide a user keyfile so that the user can authenticate to the server. You can do that with the same command as above, but on your slave and as the user running the slave process, then copy the key over:

ssh-copy-id [hidden email]

HTH...
