Git Setup on Windows - windows

So on my friends local Windows machine we are trying to setup GIT.
Basically, we've been following this guide which has been great. The problem we are facing is as follows:
All works until we get to Using Gitosis
When we use the command
git clone
git#INSERT_IP_HERE:gitosis-admin.git
We keep getting
Initialized empty Git repository in
/home/Thomas/gitosis-admin/.git
Connection closed by IP_HERE fatal:
The remote end hung up unexpectedly
When we try simply
ssh git#IP_HERE
We get "Connection closed by IP_HERE"
If we login as
runas /user:git C:/cygwin/cygwin.bat
And run > ssh git#IP_HERE
We at least get asked for a password then
Last Login: Connection to IP_HERE
closed.
Would anyone be able to help ?

The error does indeed indicate that authentication is failing.
Firstly, open gitosis.conf on the server and check that you are a member of the group containing gitosis-admin repository. It should show something like.
[gitosis]
[group gitosis-admin]
writable = gitosis-admin
members = user1 user2
The member name must match with a public key in /keydir before access can be made.
Secondly, you do not say how you are connecting from the Windows machines. If you are using Git under Cygwin, make sure you are correctly loading the private key. If you are using MsysGit with Putty, be sure to load the private key before connecting as well.
There is a small gotcha if PuttyGen is used to generate key pairs, and that is the default format is different from OpenSSH which you are probably using. Copy and paste from the top window, or alternatively edit the multiline public key file to read like this.
ssh-rsa AAAABB...KEYBODY...ONLkQ== user1
Lastly, make sure port 22 is open in any firewalls if that is indeed the port you are using.
A more comprehensive description of how to set up a Git server with Gitosis on Windows, can be found at here
I recommend the use of MsysGit from windows, as it gives better integration into the Windows environment. TortoiseGit and GitExtensions both use MsysGit as the backend, and provide nice Gui's and explorer shell extensions. GitExtensions full installer will provide the windows user with everything they need.

Did you get past runnig the gitosis-init < /tmp/id_rsa.pub command?
That error indicates to me that the public key isn't set up properly. The command above initializes gitosis with the first key.

Trouble connecting to Git server (bitbucket.org) via Win 10 Git Bash

I had to restart my machine but things were working before hand. I was using Git Bash with SSH and hoses on Win 10 to connect to BitBucket which was fine.
I then had to also connect with Git Bash (another instance) to GitHub. This required Putty and Pagent to get setup.
No I try to connect to BitBucket and get this:
git pull origin mybranch
FATAL ERROR: No supported authentication methods available (server sent: publickey)
fatal: Could not read from remote repository.
Is there a simple way to have both working in different shells?
I tried to do a plink.exe to bitbucket.org but that made things worse.
Is there a simple way to have both working in different shells?
Yes. You can use any single method (from both) for connecting to HG|BB. Just select preferred way (ssh + ssh-agent OR pageant) and perform needed steps according to relevant docs

Using VS Code with native Windows OpenSSH client

I'm trying to pass from Putty/Pagent/plink to Windows OpenSSH native client.
I already managed to do this in TortoiseGit, but with the main problem with VSCode seem to be I can't set which ssh agent to use.
I enabled the OpenSSH agent service on Windows to start automatically and added my open ssh key with ssh-add.
Every time i try to push from VSCode all i got is an error message with
Git: FATAL ERROR: Disconnected: No supported authentication methods available (server sent: public key)
When trying to push from terminal I got also
Please make sure you have the correct access rights and the repository exists.
As already said, with TortoiseGit I have no problem at all, and the only differences are that in TortoiseGit I set the ssh-agent.
you might need to confirm your System environment variable GIT_SSH points to the ssh within Git: C:\Program Files\Git\usr\bin\ssh.exe
You may need to update your Windows OpenSSH. If you run ssh -V from a PowerShell window and see OpenSSH_for_Windows_7.7p1, this is probably the case. The instructions for upgrading are available in the Install Win32 OpenSSH Wiki.
General
VS Code uses the Windows version of OpenSSH.
The config file that you change in VS Code is located in /Users/<username>/.ssh/config
The default location/name of a key is at /Users/<username>/.ssh/id_rsa.
Example
Local: Windows 10 machine with VS Code and the very awesome Remote - SSH extension installed
Remote: Ubuntu, where I use git for development and need my private key available
Since the remote is shared, I want to use SSH agent forwarding and keep my private key(s) on my local machine
Config file:
Host mybox
HostName actual.ip.or.name.of.mybox.com
User myusername
IdentityFile ~/.ssh/id_rsa
ForwardAgent yes
PowerShell Commands (Run as Administrator)
Start-Service ssh-agent
ssh-add C:\Users\<username>\.ssh\id_rsa # private key to add
ssh-add -L # list keys added
Set-Service ssh-agent -StartupType Automatic # optional

GitLab does not work with key loaded in Pageant?

I keep most of my personal projects on BitBucket by Atlassian. As a natural choice, I use SourceTree app (their product) as git GUI client on Windows, and I'm happy with it. For projects where ssh git is available, I prefer ssh over https. SourceTree plays very well with projects hosted on BitBucket. Although it offers both of ssh agents: OpenSSH or PuTTY, its default selection is PuTTY/Plink (perhaps because PuTTY is more Windows-familiar).
Recently my establishment requested to host some projects on its own server. At first look it's a git server using GitLab opensource. I can use SourceTree with project hosted here using https just fine, however when it comes to ssh, the only choice of SSH agent is OpenSSH. The only key pair it would use (unless specified in config) is ~/.ssh/id_rsa.pub and ~/.ssh/id_rsa (located in %USERPROFILE%\.ssh\
I've tried to:
Load ~/.ssh/id_rsa into PuTTY Key Generator
Convert it to PuTTY format (.ppk) file
Load the .ppk into Pageant (PuTTY authentication agent).
Despite the key being loaded and kept in the memory by Pageant, the connection with the server failed all the time, e.g. git: fatal: Could not read from remote repository. The only way to make it work is to start ssh-agent and ssh-add (go with OpenSSH).
Since I have Pageant running usually in the background, I find it more convenient to use (e.g. the keyphrase to open the private key is long/complex, and I don't remember it, and it can be copy-pasted from KeePass, while in the case of OpenSSH, cmd console does not allow me to paste it, too bad).
Is there anyway to make the ssh authentication to GitLab done via PuTTY instead of OpenSSH?
Did you connect to the SSH server using PuTTY before using plink? If not a reason could be that plink is refusing to connect to the server, because the ssh hostkey isn't verified yet. Another reason could be that the SSH server requires ciphers which are not supported by PuTTY. You can only find out if you connect with PuTTY with the same version as plink.
Use TortoiseGitPlink (from TortoiseGit) to circumvent this issue, as it will popup a messagebox asking whether to accept the hostkey or not.

Git with putty on windows

When attempting to push / pull over ssh, git is failing with the following error:
"C:\Program Files\Git\bin\git.exe" push -u --recurse-submodules=check -progress "testremote" project:project
Using username "git-receive-pack 'ec2-user".
FATAL ERROR: Disconnected: No supported authentication methods available (server sent: publickey)
fatal: Could not read from remote repository.
Please make sure you have the correct access rights and the repository exists.
Done
The remote "testremote" is setup as "ssh://ec2-user#sweeb.net:gittest.git" and I'm using an existing keypair that I have used with PuTTY before without issue.
Pageant is running, with my key loaded.
I think the issue is the line "Using username "git-receive-pack 'ec2-user"." - I assumed git's commands were breaking on windows thanks to the space in "Program Files" so I've tried to surround everything with double quotes, but that doesn't seem to be working. Has anyone seen anything like this before?
Windows vars:
GIT_SSH=C:\PuTTY\plink.exe
PATH=[...];"C:\Program Files\Git\cmd";"C:\Program Files\Git\libexec\git-core\";"C:\Program Files\Git\bin\"
This was solved by removing "ssh://", that's implicit in Git Extensions apparently.

Eclipse ADT known hosts

I have trouble getting the official Windows ADT 21.1.0 distribution to connect to a git repository. No matter what I tried(details below) it complains about host key not present in the registry and shows me no option to accept the host key. The remote server is running Gitlab and is under my control. There's no problem with connectivity or firewalls.
What I tried so far:
connecting without giving a password, with user git
connecting while giving a password, with another user
adding manually the host key in the known_hosts file that is found in the ssh home directory(Preferences->General->Network Connections->SSH2->SSH2 home).
The message is always:
The server's host key is not cached in the registry. You
have no guarantee that the server is the computer you
think it is.
The server's rsa2 key fingerprint is:
ssh-rsa 2048 xx:xx:xx...
Connection abandoned.
RSE works without any problems, only egit gives me problems.
You could workaround the problem by not using the ssh protocol with the git server, but instead the git or http protocol.
One reason for the above message can be using a folder called "ssh" instead of ".ssh" (note the dot). Some colleague of mine experienced that, and this can easily happen when using Windows explorer, as it will silently remove the dot, when creating a folder called ".ssh". You have to use the command line instead.
