Jenkins 1.580.13.1
I have a job configured that opens an SSH connection from a slave node to a remote system. This uses the ssh-agent plugin to choose a private key credential stored in Jenkins. The goal is to SSH from a Windows slave configured to use Cygwin for SSH.
The ssh command is simply:
ssh -vvv user@example.com "ls"
When run on a Linux slave, the output looks like:
authmethod_lookup publickey debug3: remaining preferred: keyboard-interactive,password debug3: authmethod_is_enabled publickey debug1: Next authentication method: publickey debug1: Offering public key: user (SSH key for example.com) debug3: send_pubkey_test debug2: we sent a publickey packet, wait for reply debug3: Wrote 368 bytes for a total of 1661 debug1: Server accepts key: pkalg ssh-rsa blen 277 debug2: input_userauth_pk_ok: SHA1 fp #### debug3: sign_and_send_pubkey: RSA #### debug3: Wrote 640 bytes for a total of 2301 debug1: Authentication succeeded (publickey).
When run on a Windows slave, the output looks like:
debug3: authmethod_lookup publickey debug3: remaining preferred: keyboard-interactive,password debug3: authmethod_is_enabled publickey debug1: Next authentication method: publickey debug1: Trying private key: /home/user/.ssh/id_rsa debug3: no such identity: /home/user/.ssh/id_rsa: No such file or directory debug1: Trying private key: /home/user/.ssh/id_dsa debug3: no such identity: /home/user/.ssh/id_dsa: No such file or directory debug1: Trying private key: /home/user/.ssh/id_ecdsa debug3: no such identity: /home/user/.ssh/id_ecdsa: No such file or directory debug1: Trying private key: /home/user/.ssh/id_ed25519 debug3: no such identity: /home/user/.ssh/id_ed25519: No such file or directory debug2: we did not send a packet, disable method debug3: authmethod_lookup password debug3: remaining preferred: ,password debug3: authmethod_is_enabled password debug1: Next authentication method: password debug1: read_passphrase: can't open /dev/tty: No such device or address debug2: we sent a password packet, wait for reply debug1: Authentications that can continue: publickey,gssapi-with-mic,password Permission denied, please try again. debug1: read_passphrase: can't open /dev/tty: No such device or address debug2: we sent a password packet, wait for reply debug1: Authentications that can continue: publickey,gssapi-with-mic,password Permission denied, please try again. debug1: read_passphrase: can't open /dev/tty: No such device or address debug2: we sent a password packet, wait for reply debug1: Authentications that can continue: publickey,gssapi-with-mic,password debug2: we did not send a packet, disable method debug1: No more authentication methods to try. Permission denied (publickey,gssapi-with-mic,password).
The difference appears to be that the credential is not sent to the slave to be used as the identity in the SSH connection.
