Jenkins Publish over ssh authentification failed with private key

Question

I can authenticate successfully with putty on the server with my private key and passphrase. But when I try to do it with jenkins publish over SSH plugin (using Test for configuration), I get the following error message:

jenkins.plugins.publish_over.BapPublisherException: Failed to connect session for config myconfig. Message [Auth fail]

I entered the same information as in putty:

Hostname : myhostname
Username : myusername
Remote Directory :

Use password authentication, or use a different key Passphrase / Password Path to key : checked
Path to key : mypath
Passphrase : mypasssword
Key:
Port:22
Timeout(ms):300000

If you have any idea ... Thanks for your help.

Answer 1

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 ~/.ssh
chmod 600 ~/.ssh/authorized_keys

Answer 2

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

Answer 3

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: [email protected]
