Jenkins Publish over ssh authentification failed with private key

Looks like you're using keyfile authentication, so you'll get this error from Jenkins if you haven't set the permissions correctly on your .ssh folder and/or ~/.ssh/authorized_keys file.

• the .ssh folder should have drwx------ permissions (read/write/execute owner only)
• the authorized_keys file should have -rw------- permissions (read/write owner only)

To fix it:

chmod 700 ~/.sshchmod 600 ~/.ssh/authorized_keys

I ran into the same issue today and it turned out i was accidentally supplying the path to the public key instead of the private one.

So the "path to key" should be something like

.ssh/id_rsa

instead of

.ssh/id_rsa.pub

Because your linux login need password, the answer is :

 1. Passphrase: your passphrase 2. path to key: your private key path 3. key : blank 4. Disable exec : un-check

SSH Servers

1. Name: remote_user@remotehost.com 2. hostname: remotehost.com 3. Username: remote_user 4. Remote Directory: empty

Advanced --

5. check the box "use passsword authentication, or use a different key"    `important` 6. Passphrase / Password: your linux login password`important` 7. path to key: blank 8. key:blank 9. port: 22 10. Timeout(ms): 300000
