ssh connection using cygwin - windows

I am trying to connect with my remote linux server using cygwin+ssh but the authentication fails with no apparent reason. I have successfully setup another connnection to github successfully and I have followed the same process, this is why I am stopped here

I have made the standard stuff but I cannot solve the problem. These are the commands I have used to generate the private/public keys. I have then copied the public key to the server
$ ssh-keygen -t dsa
Generating public/private dsa key pair.
Enter file in which to save the key (/home/xxxtta/.ssh/id_dsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/xxxtta/.ssh/id_dsa.
Your public key has been saved in /home/xxxtta/.ssh/id_dsa.pub
thank you for your help
EDIT:
I have made the same procedure using MINGW and it works (I am able to connect). Something is definitely going wrong with cygwin in my system

Problem probably lies in user name. If you login remotely user name is case sensitive. You must write user name exactly how it was defined in Windows.

Copy id_dsa.pub to your remote server.
# scp .ssh/id_dsa.pub dude#remotemachine
On remote server:
# cat id_dsa.pub >> ~/.ssh/authorized_keys

You might try -vvv instead of -v to increase the verbosity.
Also, check that the file permissions are set properly. See Adding public key to ~/.ssh/authorized_keys does not log me in automatically

Git on Windows not asking for SSH key password, or using SSH Key

The fundamental problem is that I am never seeing a prompt to enter in my SSH-Key password, SSH-Agent or no. As such, it's acting like I entered the wrong password and defaulting to pretending I have no keys.
This is happening on multiple computers. I set up my ssh keys awhile ago, and everything is great, but every so often I will do a git push (usually after restarting my computer) and I will get asked for my git origin server's password RATHER than my ssh key's password. Since my origin server does not HAVE a password, this leaves me unable to push changes.
Sometimes it resolves itself after restarting, sometimes not. Usually I do a lot of flailing guesses and one of them ends up fixing the problem, but I can't currently remember which ones work and which don't.
What is the CORRECT way to go about fixing this? What is the actual problem? Is my SSH Key locked? Is some windows process not starting correctly? Is a Path variable being eaten? I don't know a lot about windows (usually I develop on linux), so I'm extra at a loss here.
Edit: The first answer mentions ssh-agent. Some googling got me to here:
https://help.github.com/articles/working-with-ssh-key-passphrases/#platform-windows
Which explains how to set up ssh-agent to autostart and know about your keys in windows. (I didn't even know you could use bash profiles in windows).
This did not help.
My git bash now says "Identity added: /c/Users/{{ME}}/.ssh/id_rsa" It does NOT ask me for my key password, and I still cannot push to my origin server (it asks for a server password, still).
I can confirm that my ssh key does live in the place the agent is looking. I can also confirm that the key is added: ssh-add -l shows a single key, from the location my key is stored.
Edit: Setting GIT_SSH as an environment variable pointing at the executable for ssh does nothing either, but it was a long shot anyways.
Edit: ssh git#git.myhost.com outputs:
$ ssh -v git#git.myhost.lan

git#git.myhost.lan's password:
The output screen helped me take the tack that the ssh key was being used, but rejected by the server. I found that the ssh key my server knows about does not match the ssh key my machine has, somehow, despite everything working fine less than a month ago. I re-added the ssh key I have, and was able to push my changes.
Anybody have any idea how the ssh key would be re-generated (I'm fairly sure I didn't do it explicitly) during all of this?
It's not enough to add the identity. There should be a file called config(no extension) in your C:\Users\{{username}}\.ssh directory.
You can define the key to use for a given host there like this:
Host myhost.name.com
IdentityFile ~/.ssh/my_keyfile_name
The result of correct configuration is a input request for a password:
Enter passphrase for key '/c/Users/{{username}}/.ssh/my_keyfile_name':
Edit1: You can retrieve the verbose output of ssh by adding the -v parameter. Real world example (host name replaced):

I think this would help tremendously. Added comment to OP requesting this information.
you need to tell your computer to add the key again after restarting the system. Most of the time this is done with the ssh-agent
I wasted several hours trying to solve the same problem - SSH would not ask for the passphrase for my keypair even with pageant NOT running.
SSH uses different key formats (SSH-1 and SSH-2), and more importantly, refuses to read RSA keys if they are in SSH-2 format. Generating the keypair with Puttygen and then converting it to SSH-1 format to save in .ssh\id_rsa solved the problem for me.
Generate a keypair
Save it with a meaningful name (like Basement-Computer.ppk)
Export the file to OpenSSH format and save it with the name id_rsa (no extension)
Git clone will now ask for the passphrase (or at least it did for me). Google's instructions for setting up a Git repo https://cloud.google.com/source-repositories/docs/authentication#ssh neglects to mention that crucial third step.

Cannot connect to Cygwin-based OpenSSH server with authorized_keys

I have a problem with setting-up SSHD service in Windows 7 running Cygwin.
I've followed this tutorial and it worked first time, but after reboot public keys stored in ~/.ssh/authorized_keys won't allow me to access this machine from external CLI. In addition password authorization also doesn't work, i've even try to reset password in cygwin using passwd testinguser.
These are steps i've made so far:
Reinstall Cygwin SSHD service (I've also removed other Windows user accounts than testinguser)
Re-run ssh-host-config again, as mentioned in tutorial
reset testinguser password from Cygwin console
set privileges to .authorized_keys & parent folder:
chmod 700 ~/.ssh &
chmod 600 ~/.ssh/authorized_keys
disabled Windows Defender Firewall and other AV software (httpd works well)
below is the result of ssh <host> -v command:

Is there something else that I should check? SSHD service is running correctly, I can start&stop it without any errors.

Connecting to EC2 Instance via Terminal on Mac

I am completely new to coding and am doing a startup course on coursera: https://class.coursera.org/startup-001/lecture/87
I'm getting a Permission Denied (publickey) when trying to connect to an EC2 Ubuntu Instance I created on AWS
Set up AWS Istance
Set Security to default and added port 22 and launched
Course tells me to then type:
chmod 400 trevor-learning.pem
ssh -i trevor-learning.pem \ ec2-user#ec2-XX-XXX-XX-XX.us-west-2.compute.amazonaws.com
This then gives me this error: Permission denied (publickey).
I've looked at other questions asked and tried switching the ubuntu# to ec2-user and some other things but I still can't connect.
I also tried:
trevor-larsons-macbook-pro:downloads trev$ chmod 600 trevor-learning.pem
trevor-larsons-macbook-pro:downloads trev$ ssh -v -i trevor-learning ubuntu#ec2-XX-XXX-XX- XX.us-west-2.compute.amazonaws.com

Stuck with Gitolite on OSX

I am in the process of installing the latest version of gitolite on an osx mountain lion server. I set it up under it's own 'git' user account and followed the instructions here: https://github.com/sitaramc/gitolite
I am getting stuck in trying to check-out the gitolite-admin repo from the server on my workstation. I run this command:
git clone git#gitserver:gitolite-admin
but get this in return:
Cloning into 'gitolite-admin'...
Connection closed by gitserver
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
It seems that I got the SSH set-up correctly because it's not asking for a PWD but I am stuck on where to look to try to debug the problem.
Thanks,
Grant

Looks OK here unless I am missing some detail.
I had a similar issue configuring a bare git repo in mountain lion. I uncommented the following lines of /etc/sshd_config:
PubkeyAuthentication yes
PermitUserEnvironment yes
The last one was related to the missing PATH error in .ssh/environment, but the first one was the one that allowed connections from ie. msysgit.
PS (edit): In the case of msysgit, I also setup the SSH agent (eval $(ssh-agent) && ssh-add) with OpenSSH key imported in pageant (as my GIT_SSH=path_to_plink). That did the trick.
On osx server, at least since 2015, also enable ssh access explicitly for the repository owner. In my case I have my server configured to allow only a few users. This caused very similar problems like you had.

Add a new key to EC2

I'm on a Mac now and previously I was able to set up and access an EC2 instance successfully from Windows XP. I want to create a new key for access from Mac, used the console management screen to generate a new key, saved the PEM file, changed permission on the file to owner RW only and then tried ssh but couldn't get it to work.

Anyone know what I'm missing? Oh and I am able to ssh into a different instance with the original key created for that instance making this even more puzzling.
Permissions are set correctly using chmod 600. The one thing I'm not sure is in the control panel management screen when I list Instances, it only shows the original value in "Key Pair Name" column, should it show both?
Thanks for your help in advance.
You don't need to create new key for new operating system. You can make use of your old Windows XP key in MAC.
Another point is when you launch an instance with a private key, then you can only login through that key only. A new key won't help.

Sanket Dangi
