I'm trying to ssh from a server into a Mac (mac1) and then from that mac into another (Mac2) using agent forwarding. Both are accessible through the server but don't have the keys to access each other.
I have this config file in the server's ~/.ssh/config:
Host *
ForwardAgent yes
And then this file in mac1's /etc/sshd_config:
AllowAgentForwarding yes
Then I log into mac1 with agent-forwarding option:
[brandon's_server]$ ssh -Av root#mac1

I seem to have a socket:
mac1>echo $SSH_AUTH_SOCK
/tmp/ssh-0cpmpDpPo9/agent.1941
Then I run ssh-add with no arguments.
The ssh agent gives me this on mac1:
mac1:~ root# ssh-agent
SSH_AUTH_SOCK=/var/folders/zz/zyxvpxvq6csfxvn_n0000000000000/T//ssh-QOl0KPFzqDTK/agent.4209; export SSH_AUTH_SOCK;
SSH_AGENT_PID=4211; export SSH_AGENT_PID;
echo Agent pid 4211;
However when I run the second ssh from mac1 to mac2 I get:

I believe I got it to work once. But I can't figure out how I did it. Thoughts?

Using git with ssh-agent on Windows
(6 answers)
Closed 8 months ago.
I'm using git in PowerShell on Windows. I made sure ssh-agent is running, and ssh-add has my private key.
$ Get-Service ssh-agent
Status Name DisplayName
------ ---- -----------
Running ssh-agent OpenSSH Authentication Agent
$ ssh-add -l
256 SHA256:2MDH36ZZcM1uf9wQ2tsMj4NROkiGeKUD+CwBsVXrKXY xxxxxxxxxx#gmail.com (ED25519)
But git still asks for passphrase every time. I tried to debug by setting GIT_SSH_COMMAND="ssh -vvv", but couldn't understand what's wrong. Below is the verbose output when I run git push.

As mentioned here by Ajedi32, if you are using Windows' native implementation of OpenSSH with the native ssh-agent Windows service, make sure that Git for Windows was configured to use that SSH implementation when you installed it
You can force using another ssh.exe with the GIT_SSH environment variable.
Try also to start the agent as a service.
Try to run these two lines one after another in this order in git bash, Windows WLS or bash on real GNU/Linux.
eval ssh-agent -s
ssh-add ~/.ssh/*_rsa
it will ask for passphrase in the second command, and that's it. Each additional action you will need to do (which normally requires passphrase) won't ask you for the passphrase.

I have tried the solutions suggested in other posts (e.g changing permissions of the id_rsa file, enabling remote login for all users, etc.)
Looking inside the system.log, I see the following line corresponding to my ssh attempt:
Apr 1 13:02:43 XXXX com.apple.xpc.launchd[1] (com.openssh.sshd.F213F0E3-6EE9-43DE-AD5F-B9407F5FA7A4[22997]): Service exited with abnormal code: 255
Which is not particularly informative...

debug1: Skipping ssh-dss key /Users/chen/.ssh/id_dsa - not in PubkeyAcceptedKeyTypes
This line says that the client has only DSA host key. This is considered weak these days with fixed length of 1024 bits. You should update the server and set up different keys (RSA).
As a workaround, you can use PubkeyAcceptedKeyTypes +ssh-dss in ~/.ssh/config, which will allow you to connect using this ke, exactly as described in the official documentation for legacy algorithms in OpenSSH.
Since you didn't mention the steps you followed for password-less authentication i am not so sure about the problem.
Anyways give a try with the following
ssh-keygen -t rsa
hit enter to all the prompt questions.
cd ~/.ssh
cat id_rsa.pub >> authorized_keys
Part of the installation for Hadoop requires a passwordless connection to localhost via ssh. The instructions are rather simple
$ ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa
$ cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
$ ssh -vv localhost

Password:
But it keeps asking for password. I tried many things but I'll try to keep this as short as possible.
Remote logging is enabled
Just in case I cleaned my ~./ssh directory completely and then generated the keys
Out of curiosity I tried from a vanilla user account on my computer and those simple steps are working
I previously had to fiddle with ssh for Git and connection to remote server for a job
As far as I know, /etc/ssh/ is system wide and since the vanilla user is working I'm assuming that I don't have to play with that, although I did try to change a couple of those parameters just in case
I created RSA and DSA just in case
I changed the permission of ~/.ssh/authorized_keys to 600, but the vanilla user has 644 and it still works
So that sum up the steps I tried. I know there are many posts out there about this issue, but I get the feeling it's not the usual suspect. Maybe you can point me in the right direction that would help find the difference between my account and the vanilla one.
Ok I've finally found it! I just learned about /var/log/system.log where I saw this bit of information
User [me] not allowed because shell /usr/local/bin/zsh does not exist
So I looked at it
$ file /usr/local/bin/zsh
/usr/local/bin/zsh: broken symbolic link to ../Cellar/zsh/5.1/bin/zsh
Broken link...
brew install zsh
et voilà!
I got the following task in an ansible playbook...
- name: Check if default ssh user exist
shell: whoami
remote_user: "{{default_ssh_user_info.name}}"
ignore_errors: yes
register: results
The objective is to check if the user {{default_ssh_user_info.name}} is configured on the remote machine, in case it is not, I would connect as a root user and create it with the following tasks.
However, it looks that ignore_errors does not catch the error... and this my ansible playbook stop. Is there a way to catch this kind of error ? Is it a bug ?
Here are the error messages:

FATAL: all hosts have already failed -- aborting
FOLLOW-UP
I am trying the following solution:
- name: Check if default ssh user exist
shell: id -u {{ default_ssh_user_info.name }}
remote_user: "{{ init_ssh_user_info.name }}"
ignore_errors: yes
register: results
sudo: yes
when: init_ssh_user_info.name is defined
The only problem I have it is that the SSH connection still fails as it does not find the private key. Is it possible to specify the path of the private key for a specific task in Ansible ? I could not find it in the documentation.
The thing here is, Ansible does not fail directly on your task, but already while connecting to the host. That is a fatal error and you can not ignore_errors on this level.
You have three options I see,
Run the task as root (not necessarily, if you have another user that you know exists for sure, you can use that) and check if the user exists:
- shell: id -u {{ default_ssh_user_info.name }}
register: results
sudo: yes
Create your own ssh connection through a shell task:
- shell: ssh {{ default_ssh_user_info.name }}#{{ inventory_hostname }} whoami
delegate: localhost
register: results
But I wonder why you need such a check in the first place. When you use the user module Ansible would only create the user if it does not exist (erm... how could it not ;-)). If you want to trigger own actions depending on if the user was just created, you can register that output and check for the changed property.
- user: name={{ default_ssh_user_info.name }}
sudo: yes
register: user_created
- debug: msg="User was created"
when: user_created | changed
