I have a gitlab installation and I am trying to setup a gitlab-runner using a docker executor. All ok until tests start running and then since my projects are private and they have no http access enabled, they fail at clone time with:

I have looked into https://docs.gitlab.com/ee/ci/ssh_keys/README.html
and decided to give it a try so my .gitlab-ci.yml starts with:
image: fedora:26
before_script:
# Install ssh-agent if not already installed, it is required by Docker.
# (change apt-get to yum if you use a CentOS-based image)
- 'which ssh-agent || ( apt-get update -y && apt-get install openssh-client -y )'

... JOBS...
I setup the SSH_PRIVATE_KEY correctly, etc but the issue is that the cloning of the project happens before before_script. I then tried to start the container with -v /home/pmatos/gitlab-runner_ssh:/root/.ssh but still the cloning is trying to use HTTP. How can I force the container to clone through ssh?
Due to the way gitlab CI works, CI requires https access to the repository. Therefore if you enable CI, you need to have https repo access enabled as well.
This is however, not an issue privacy wise as making the container https accessible doesn't stop gitlab from checking if you're authorized to access it.
I then tried to start the container with -v /home/pmatos/gitlab-runner_ssh:/root/.ssh but still the cloning is trying to use HTTP
Try at least if possible within your container to add a
git config --global url.ssh://git#.insteadOf https://
(assuming the ssh user is git)
That would make any clone of any https URL use ssh.
I am creating a restricted user without shell for port forwarding only and I need to execute a script on login via pubkey, even if the user is connected via ssh -N user#host which doesn't asks SSH server for a shell.
The script should warn admin on connections authenticated with pubkey, so the user connecting shouldn't be able to skip the execution of the script (e.g., by connecting with ssh -N).
I have tried to no avail:
Setting the command at /etc/ssh/sshrc.
Using command="COMMAND" in .ssh/authorized_keys (man authorized_keys)
Setting up a script with the command as user's shell. (chsh -s /sbin/myscript.sh USERNAME)
Matching user in /etc/ssh/sshd_config like:
Match User MYUSERNAME
ForceCommand "/sbin/myscript.sh"
All work when user asks for shell, but if logged only for port forwarding and no shell (ssh -N) it doesn't work.
The ForceCommand option runs without a PTY unless the client requests one. As a result, you don't actually have a shell to execute scripts the way you might expect. In addition, the OpenSSH SSHD_CONFIG(5) man page clearly says:
The command is invoked by using the user's login shell with the -c option.
That means that if you've disabled the user's login shell, or set it to something like /bin/false, then ForceCommand can't work. Assuming that:
the user has a sensible shell defined,
that your target script is executable, and
that your script has an appropriate shebang line
then the following should work in your global sshd_config file once properly modified with the proper username and fully-qualified pathname to your custom script:
Match User foo
ForceCommand /path/to/script.sh
If you only need to run a script you can rely on pam_exec.
Basically you reference the script you need to run in the /etc/pam.d/sshd configuration:
session optional pam_exec.so seteuid /path/to/script.sh
After some testing you may want to change optional to required.
Please refer to this answer "bash - How do I set up an email alert when a ssh login is successful? - Ask Ubuntu" for a similar request.
Indeed in the script only a limited subset on the environment variables is available:
LANGUAGE=en_US.UTF-8
PAM_USER=bitnami
PAM_RHOST=192.168.1.17
PAM_TYPE=open_session
PAM_SERVICE=sshd
PAM_TTY=ssh
LANG=en_US.UTF-8
LC_ALL=en_US.UTF-8
PWD=/

I am the author of the OP; I came to the conclusion that what I need to achieve is not possible using SSH only to the date (OpenSSH_6.9p1 Ubuntu-2, OpenSSL 1.0.2d 9 Jul 2015), but I found a great piece of software that uses encrypted SPAuthentication to open SSH port and it's new version (to the date of this post, it's GitHub master branch) has a feature to execute a command always that a user authorizates successfully.
FWKNOP - Encrypted Single Packet Authorization
FWKNOP set iptables rules that allow access to given ports upon a single packet encrypted which is sent via UDP. Then after authorization it allow access for the authorized user for a given time, for example 30 seconds, closing the port after this, leaving the connection open.
1. To install on an Ubuntu linux:
The current version (2.6.0-2.1build1) on Ubuntu repositories to the date still doesn't allow command execution on successful SPA; (please use 2.6.8 from GitHub instead)
On client machine:
sudo apt-get install fwknop-client
On server side:
sudo apt-get install fwknop-server
Here is a tutorial on how to setup the client and server machines
https://help.ubuntu.com/community/SinglePacketAuthorization
Then, after it is set up, on server side:
Edit /etc/default/fwknop-server
Change the line START_DAEMON="no" to START_DAEMON="yes"
Then run:
sudo service fwknop-server stop
sudo service fwknop-server start
2. Warning admin on successful SPA (email, pushover script etc)
So, as stated above the current version present in Ubuntu repositories (2.6.0-2.1build1) cannot execute command on successful SPA. If you need this feature as of the OP, but it will be released at fwknop version (2.6.8), as can it is stated here:
https://github.com/mrash/fwknop/issues/172
So if you need to use it right now you can build from github branch master which have the CMD_CYCLE_OPEN option.
3. More resources on fwknop

I am the author of the OP. Also, you can implement a simple logwatcher as the following written in python3, which keeps reading for a file and executes a command when line contains pattern.
logwatcher.python3
#!/usr/bin/env python3
# follow.py
#
# Follow a file like tail -f.
import sys
import os
import time
def follow(thefile):
thefile.seek(0,2)
while True:
line = thefile.readline()
if not line:
time.sleep(0.5)
continue
yield line
if __name__ == '__main__':
logfilename = sys.argv[1]
pattern_string = sys.argv[2]
command_to_execute = sys.argv[3]
print("Log filename is: {}".format(logfilename))
logfile = open(logfilename, "r")
loglines = follow(logfile)
for line in loglines:
if pattern_string in line:
os.system(command_to_execute)
Usage
Make the above script executable:
chmod +x logwatcher.python3
Add a cronjob to start it after reboot
crontab -e
Then write this line there and save it after this:
#reboot /home/YOURUSERNAME/logwatcher.python3 "/var/log/auth.log" "session opened for user" "/sbin/myscript.sh"
The first argument of this script is the log file to watch, and the second argument is the string for which to look in it. The third argument is the script to execute when the line is found in file.
It is best if you use something more reliable to start/restart the script in case it crashes.
I am running into this error of:
$ git push heroku master
Warning: Permanently added the RSA host key for IP address '50.19.85.132' to the list of known hosts.
! Your key with fingerprint b7:fd:15:25:02:8e:5f:06:4f:1c:af:f3:f0:c3:c2:65 is not authorized to access bitstarter.
I tried to add the keys and I get this error below:
$ ssh-add ~/.ssh/id_rsa.pub
Could not open a connection to your authentication agent.
Did You Start ssh-agent?
You might need to start ssh-agent before you run the ssh-add command:
eval `ssh-agent -s`
ssh-add
Note that this will start the agent for msysgit Bash on Windows. If you're using a different shell or operating system, you might need to use a variant of the command, such as those listed in the other answers.
See the following answers:
ssh-add complains: Could not open a connection to your authentication agent
Git push requires username and password (contains detailed instructions on how to use ssh-agent)
How to run (git/ssh) authentication agent?.
Could not open a connection to your authentication agent
To automatically start ssh-agent and allow a single instance to work in multiple console windows, see Start ssh-agent on login.
Why do we need to use eval instead of just ssh-agent?
SSH needs two things in order to use ssh-agent: an ssh-agent instance running in the background, and an environment variable set that tells SSH which socket it should use to connect to the agent (SSH_AUTH_SOCK IIRC). If you just run ssh-agent then the agent will start, but SSH will have no idea where to find it.
from this comment.
Public vs Private Keys
Also, whenever I use ssh-add, I always add private keys to it. The file ~/.ssh/id_rsa.pub looks like a public key, I'm not sure if that will work. Do you have a ~/.ssh/id_rsa file? If you open it in a text editor, does it say it's a private key?
I tried the other solutions to no avail. I made more research and found that the following command worked. I am using Windows 7 and Git Bash.
eval $(ssh-agent)
More information in: https://coderwall.com/p/rdi_wq (web archive version)
The following command worked for me. I am using CentOS.
exec ssh-agent bash
Could not open a connection to your authentication agent
To resolve this error:
bash:
$ eval `ssh-agent -s`
tcsh:
$ eval `ssh-agent -c`
Then use ssh-add as you normally would.
Hot Tip:
I was always forgetting what to type for the above ssh-agent commands, so I created an alias in my .bashrc file like this:
alias ssh-agent-cyg='eval `ssh-agent -s`'
Now instead of using ssh-agent, I can use ssh-agent-cyg
E.g.
$ ssh-agent-cyg
SSH_AUTH_SOCK=/tmp/ssh-n16KsxjuTMiM/agent.32394; export SSH_AUTH_SOCK;
SSH_AGENT_PID=32395; export SSH_AGENT_PID;
echo Agent pid 32395;
$ ssh-add ~/.ssh/my_pk
Original Source of fix:
http://cygwin.com/ml/cygwin/2011-10/msg00313.html
MsysGit or Cygwin
If you're using Msysgit or Cygwin you can find a good tutorial at SSH-Agent in msysgit and cygwin and bash:
Add a file called .bashrc to your home folder.
Open the file and paste in:
#!/bin/bash
eval `ssh-agent -s`
ssh-add
This assumes that your key is in the conventional ~/.ssh/id_rsa location. If it isn't, include a full path after the ssh-add command.
Add to or create file ~/.ssh/config with the contents
ForwardAgent yes
In the original tutorial the ForwardAgent param is Yes, but it's a typo. Use all lowercase or you'll get errors.
Restart Msysgit. It will ask you to enter your passphrase once, and that's it (until you end the session, or your ssh-agent is killed.)
Mac/OS X
If you don't want to start a new ssh-agent every time you open a terminal, check out Keychain. I'm on a Mac now, so I used the tutorial ssh-agent with zsh & keychain on Mac OS X to set it up, but I'm sure a Google search will have plenty of info for Windows.
Update: A better solution on Mac is to add your key to the Mac OS Keychain:
ssh-add -K ~/.ssh/id_rsa
Simple as that.
Run
ssh-agent bash
ssh-add
To get more details you can search
ssh-agent
or run
man ssh-agent
ssh-add and ssh (assuming you are using the openssh implementations) require an environment variable to know how to talk to the ssh agent. If you started the agent in a different command prompt window to the one you're using now, or if you started it incorrectly, neither ssh-add nor ssh will see that environment variable set (because the environment variable is set locally to the command prompt it's set in).
You don't say which version of ssh you're using, but if you're using cygwin's, you can use this recipe from SSH Agent on Cygwin:
# Add to your Bash config file
SSHAGENT=/usr/bin/ssh-agent
SSHAGENTARGS="-s"
if [ -z "$SSH_AUTH_SOCK" -a -x "$SSHAGENT" ]; then
eval `$SSHAGENT $SSHAGENTARGS`
trap "kill $SSH_AGENT_PID" 0
fi
This will start an agent automatically for each new command prompt window that you open (which is suboptimal if you open multiple command prompts in one session, but at least it should work).
I faced the same problem for Linux, and here is what I did:
Basically, the command ssh-agent starts the agent, but it doesn't really set the environment variables for it to run. It just outputs those variables to the shell.
You need to:
eval `ssh-agent`
and then do ssh-add. See Could not open a connection to your authentication agent.
Instead of using ssh-agent -s, I used eval `ssh-agent -s` to solve this issue.
Here is what I performed step by step (step 2 onwards on Git Bash):
Cleaned up my .ssh folder at C:\user\<username>\.ssh\
Generated a new SSH key:
ssh-keygen -t rsa -b 4096 -C "xyz#abc.com"
Check if any process id(ssh agent) is already running.
ps aux | grep ssh
(Optional) If found any in step 3, kill those
kill <pids>
Started the SSH agent
$ eval `ssh-agent -s`
Added SSH key generated in step 2 to the SSH agent
ssh-add ~/.ssh/id_rsa
Try to do the following steps:
Open Git Bash and run: cd ~/.ssh
Try to run agent: eval $(ssh-agent)
Right now, you can run the following command: ssh-add -l
In Windows 10 I tried all answers listed here, but none of them seemed to work. In fact, they give a clue. To solve a problem, simply you need three commands. The idea of this problem is that ssh-add needs the SSH_AUTH_SOCK and SSH_AGENT_PID environment variables to be set with the current ssh-agent sock file path and pid number.
ssh-agent -s > temp.txt
This will save the output of ssh-agent in a file. The text file content will be something like this:
SSH_AUTH_SOCK=/tmp/ssh-kjmxRb2764/agent.2764; export SSH_AUTH_SOCK;
SSH_AGENT_PID=3044; export SSH_AGENT_PID;
echo Agent pid 3044;
Copy something like "/tmp/ssh-kjmxRb2764/agent.2764" from the text file and run the following command directly in the console:
set SSH_AUTH_SOCK=/tmp/ssh-kjmxRb2764/agent.2764
Copy something like "3044" from the text file and run the following command directly in the console:
set SSH_AGENT_PID=3044
Now when environment variables (SSH_AUTH_SOCK and SSH_AGENT_PID) are set for the current console session, run your ssh-add command and it will not fail again to connect to ssh agent.
One thing I came across was that eval did not work for me using Cygwin, what worked for me was ssh-agent ssh-add id_rsa.
After that I came across an issue that my private key was too open, the solution I managed to find for that (from here):
chgrp Users id_rsa
as well as
chmod 600 id_rsa
finally I was able to use:
ssh-agent ssh-add id_rsa
For Windows users, I found cmd eval `ssh-agent -s` didn't work, but using Git Bash worked a treat:
eval `ssh-agent -s`; ssh-add KEY_LOCATION
And making sure the Windows service "OpenSSH Key Management" wasn't disabled.
To amplify on n3o's answer for Windows 7...
My problem was indeed that some required environment variables weren't set, and n3o is correct that ssh-agent tells you how to set those environment variables, but doesn't actually set them.
Since Windows doesn't let you do "eval," here's what to do instead:
Redirect the output of ssh-agent to a batch file with
ssh-agent > temp.bat
Now use a text editor such as Notepad to edit temp.bat. For each of the first two lines:
Insert the word "set" and a space at the beginning of the line.
Delete the first semicolon and everything that follows.
Now delete the third line. Your temp.bat should look something like this:
set SSH_AUTH_SOCK=/tmp/ssh-EorQv10636/agent.10636
set SSH_AGENT_PID=8608
Run temp.bat. This will set the environment variables that are needed for ssh-add to work.
I just got this working. Open your ~/.ssh/config file.
Append the following-
Host github.com
IdentityFile ~/.ssh/github_rsa
The page that gave me the hint Set up SSH for Git
said that the single space indentation is important... though I had a configuration in here from Heroku that did not have that space and works properly.
If you follow these instructions, your problem would be solved.
If you’re on a Mac or Linux machine, type:
eval "$(ssh-agent -s)"
If you’re on a Windows machine, type:
ssh-agent -s
I had the same problem on Ubuntu and the other solutions didn't help me.
I finally realized what my problem was. I had created my SSH keys in the /root/.ssh folder, so even when I ran ssh-add as root, it couldn't do its work and kept saying:
Could not open a connection to your authentication agent.
I created my SSH public and private keys in /home/myUsername/ folder and I used
ssh-agent /bin/sh
Then I ran
ssh-add /home/myUsername/.ssh/id_rsa
And problem was solved this way.
Note: For accessing your repository in Git, add your Git password when you are creating SSH keys with ssh-keygen -t rsa -C "your Git email here".
Let me offer another solution. If you have just installed Git 1.8.2.2 or thereabouts, and you want to enable SSH, follow the well-writen directions.
Everything through to Step 5.6 where you might encounter a slight snag. If an SSH agent is already be running you could get the following error message when you restart bash
Could not open a connection to your authentication agent
If you do, use the following command to see if more than one ssh-agent process is running
ps aux | grep ssh
If you see more than one ssh-agent service, you will need to kill all of these processes. Use the kill command as follows (the PID will be unique on your computer)
kill <PID>
Example:
kill 1074
After you have removed all of the ssh-agent processes, run the px aux | grep ssh command again to be sure they are gone, then restart Bash.
Voila, you should now get something like this:
Initializing new SSH agent...
succeeded
Enter passphrase for /c/Users/username/.ssh/id_rsa:
Now you can continue on Step 5.7 and beyond.
This will run the SSH agent and authenticate only the first time you need it, not every time you open your Bash terminal. It can be used for any program using SSH in general, including ssh itself and scp. Just add this to /etc/profile.d/ssh-helper.sh:
ssh-auth() {
# Start the SSH agent only if not running
[[ -z $(ps | grep ssh-agent) ]] && echo $(ssh-agent) > /tmp/ssh-agent-data.sh
# Identify the running SSH agent
[[ -z $SSH_AGENT_PID ]] && source /tmp/ssh-agent-data.sh > /dev/null
# Authenticate (change key path or make a symlink if needed)
[[ -z $(ssh-add -l | grep "/home/$(whoami)/.ssh/id_rsa") ]] && ssh-add
}
# You can repeat this for other commands using SSH
git() { ssh-auth; command git "$#"; }
Note: this is an answer to this question, which has been merged with this one.
That question was for Windows 7, meaning my answer was for Cygwin/MSYS/MSYS2. This one seems for some Unix, where I wouldn't expect the SSH agent needing to be managed like this.
The basic solution to run ssh-agent is answered in many answers. However runing ssh-agent many times (per each opened terminal or per remote login) will create a many copies ot ssh-agent running in memory. The scripts which is suggested to avoid that problem is long and need to write and/or copy separated file or need to write too many strings in ~/.profile or ~/.schrc. Let me suggest simple two string solution:
For sh, bash, etc:
# ~/.profile
if ! pgrep -q -U `whoami` -x 'ssh-agent'; then ssh-agent -s > ~/.ssh-agent.sh; fi
. ~/.ssh-agent.sh
For csh, tcsh, etc:
# ~/.schrc
sh -c 'if ! pgrep -q -U `whoami` -x 'ssh-agent'; then ssh-agent -c > ~/.ssh-agent.tcsh; fi'
eval `cat ~/.ssh-agent.tcsh`
What is here:
search the process ssh-agent by name and by current user
create appropriate shell script file by calling ssh-agent and run ssh-agent itself if no current user ssh-agent process found
evaluate created shell script which configure appropriate environment
It is not necessary to protect created shell script ~/.ssh-agent.tcsh or ~/.ssh-agent.sh from another users access because: at-first communication with ssh-agent is processed through protected socket which is not accessible to another users, and at-second another users can found ssh-agent socket simple by enumeration files in /tmp/ directory. As far as about access to ssh-agent process it is the same things.
In Windows 10, using the Command Prompt terminal, the following works for me:
ssh-agent cmd
ssh-add
You should then be asked for a passphrase after this:
Enter passphrase for /c/Users/username/.ssh/id_rsa:
Try the following:
ssh-agent sh -c 'ssh-add && git push heroku master'
Use parameter -A when you connect to server, example:
ssh -A root#myhost
from man page :
-A Enables forwarding of the authentication agent connection.
This can also be specified on a per-host basis in a configuration file.
Agent forwarding should be enabled with caution. Users with the ability to bypass file permissions on the remote host (for the agent's
UNIX-domain socket) can access the local agent through the forwarded
connection. An attacker cannot obtain key material from the agent,
however they can perform operations on the keys that enable them to
authenticate using the identities loaded into the agent.
I had this problem, when I started ssh-agent, when it was already running. It seems that the multiple instances conflict with each other.
To see if ssh-agent is already running, check the value of the SSH_AGENT_SOCK environment variable with:
echo $SSH_AGENT_SOCK
If it is set, then the agent is presumably running.
To check if you have more than one ssh-agent running, you can review:
ps -ef | grep ssh
Of course, then you should kill any additional instances that you created.
Read user456814's answer for explanations. Here I only try to automate the fix.
If you using a Cygwin terminal with Bash, add the following to the $HOME/.bashrc file. This only starts ssh-agent once in the first Bash terminal and adds the keys to ssh-agent. (I am not sure if this is required on Linux.)
###########################
# start ssh-agent for
# ssh authentication with github.com
###########################
SSH_AUTH_SOCK_FILE=/tmp/SSH_AUTH_SOCK.sh
if [ ! -e $SSH_AUTH_SOCK_FILE ]; then
# need to find SSH_AUTH_SOCK again.
# restarting is an easy option
pkill ssh-agent
fi
# check if already running
SSH_AGENT_PID=`pgrep ssh-agent`
if [ "x$SSH_AGENT_PID" == "x" ]; then
# echo "not running. starting"
eval $(ssh-agent -s) > /dev/null
rm -f $SSH_AUTH_SOCK_FILE
echo "export SSH_AUTH_SOCK=$SSH_AUTH_SOCK" > $SSH_AUTH_SOCK_FILE
ssh-add $HOME/.ssh/github.com_id_rsa 2>&1 > /dev/null
#else
# echo "already running"
fi
source $SSH_AUTH_SOCK_FILE
Don’t forget to add your correct keys in the "ssh-add" command.
I had a similar problem when I was trying to get this to work on Windows to connect to the stash via SSH.
Here is the solution that worked for me.
Turns out I was running the Pageant ssh agent on my Windows box - I would check what you are running. I suspect it is Pageant as it comes as default with PuTTY and WinSCP.
The ssh-add does not work from command line with this type of agent
You need to add the private key via the Pageant UI window which you can get by double-clicking the Pageant icon in the taskbar (once it is started).
Before you add the key to Pageant you need to convert it to PPK format. Full instructions are available here How to convert SSH key to ppk format
That is it. Once I uploaded my key to stash I was able to use Sourcetree to create a local repository and clone the remote.
For Bash built into Windows 10, I added this to file .bash_profile:
if [ -z $SSH_AUTH_SOCK ]; then
if [ -r ~/.ssh/env ]; then
source ~/.ssh/env
if [ `ps -p $SSH_AGENT_PID | wc -l` = 1 ]; then
rm ~/.ssh/env
unset SSH_AUTH_SOCK
fi
fi
fi
if [ -z $SSH_AUTH_SOCK ]; then
ssh-agent -s | sed 's/^echo/#echo/'> ~/.ssh/env
chmod 600 ~/.ssh/env
source ~/.ssh/env > /dev/null 2>&1
fi
Using Git Bash on Windows 8.1 E, my resolution was as follows:
eval $(ssh-agent) > /dev/null
ssh-add ~/.ssh/id_rsa
I resolved the error by force stopping (killed) git processes (ssh agent), then uninstalling Git, and then installing Git again.
This worked for me.
In the CMD window, type the following command:
cd path-to-Git/bin # (for example,cd C:\Program Files\Git\bin)
bash
exec ssh-agent bash
ssh-add path/to/.ssh/id_rsa
