This is for the nth time that I'm trying to connect to my github account and its becoming increasingly frustrating at my failure to do this.

I followed this tutorial step by step Github setup on windows but I failed at step 5, i.e. Test everything out.

ssh [email protected]

gives me this

ssh: github.com: no address associated with name

Any ideas what is wrong? Any help would be greatly appreciated.

I'm using the default git installation which comes with railsinstaller on Windows XP (behind a proxy)

You need to at least set an HTTP_PROXY variable environment.

set HTTPS_PROXY=http://<login_internet>:<password_internet>@aproxy:aport set HTTP_PROXY=http://<login_internet>:<password_internet>@aproxy:aport

Or, for bash session:

 export http_proxy=http://<login_internet>:<password_internet>@aproxy:aport export https_proxy=http://<login_internet>:<password_internet>@aproxy:aport

Make sure %HOME% (or $HOME) is set to a directory where you did store your .ssh config

Then, for git commands:

git config --system http.sslcainfo \\bin\\curl-ca-bundle.crt git config --global http.proxy http://<login_internet>:<password_internet>@aproxy:aport git config --global user.name <short_username> git config --global user.email <email> git config --global github.user <github_username> git config --global github.token <github_token>

Note: for bash session:

git config --system http.sslcainfo /bin/curl-ca-bundle.crt

To avoid GitHub asking for your password, create a _netrc file in your HOME (or a .netrc for bash session)

machine github.com login <login_github> password <password_github>

Update 2012

Note that since git1.7.10 (2012), you can use a credential caching mechanism in order to avoid having to store in plain text your login/password (in a %HOME%/_netrc file).

If your having an error about \\bin \\ curl-ca-bundle.crt, you can use: git config --global http.sslverify "false"
@GonzaloJarjury That would not be a practice I would recommend. Always try to verify your certificates. Try first, even on Windows with recent version of Git: git config --system http.sslcainfo /ssl/certs/ca-bundle.crt
Is <login_internet> the WiFi name?
@McFloofenbork 8 years later, I believe the "login_internet" represents your login account you would use to authenticate to the proxy.
what are the <login_internet> and <login_password>?

For those who don't have a proxy enabled and the problem persists, I found the solution! It's a problem with Yosemite. Apple replaced the mDNSResponder by the discoveryd. It's a service and you can unload and load it back:

sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.discoveryd.plist sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.discoveryd.plist

This post explains every detail:

It worked for me!

in edge cases it might not be the proxy that is causing the issues more like the DNS settings.

Test if DNS resolve works or not

nslookup archive.ubuntu.com

If correctly setup, you will see IP address, if broken you will see error message.

How to check DNS config (Ubuntu) cat /etc/resolv.conf

# This file was automatically generated by WSL. T># [network] # generateResolvConf = false nameserver 8.8.8.8 nameserver 8.8.4.4

You can use these two Google DNS Servers for testing.

Try nslookup command again. If it works now, It´s been an DNS issue all along.

Test github connection

  1. SSH
ssh -T [email protected]

Output if successfull will look something like this

This key is not known by any other names Are you sure you want to continue connecting (yes/no/[fingerprint])? yes Warning: Permanently added 'github.com' (ED25519) to the list of known hosts. Hi <YourUsername>! You've successfully authenticated, but GitHub does not provide shell access.
  1. HTTPS Try simply do clone e.g. git clone https://github.com/octocat/Spoon-Knife

If issues are fixed, it will prompt for username and password.

thanks! I've got suddenly "fatal: unable to access 'github.com...': Could not resolve host: github.com" by given "git pull". Updating /etc/resolv.conf like here helped.

If you are behind a proxy, are you also behind a firewall? Please try to run ssh -v [email protected] to see what's going on behind the scenes. For my setup, my ~/.ssh/config looks like this:

Host github.com ProxyCommand /c/windows/connect.exe -H name_of_proxy:8080 %h %p User git Port 443 Hostname ssh.github.com TCPKeepAlive yes IdentitiesOnly yes

The ProxyCommand is described here.

Yes, I'm behind a firewall. However, the proxy i'm using is a script and not a static address. How can I take that into account in the config file?

It seems like you might not have configured your SSH config properly. The reason github.com is unresolvable is because you are probably pointed to a DNS server that doesn't resolve queries outside your domain.

I wrote a whole blog post about this so take a look here: http://returnbooleantrue.blogspot.com/2009/06/using-github-through-draconian-proxies.html

Hope this helps.
