Using gitolite in a non standard ssh port

kosmas — Tue, 12 Jul 2011 22:12:51 +0000

Problem
You have moved your gitolite server or you want to be able to access your gitolite server behind a firewall and port 22 for ssh is no longer available.

Solution
Edit your .git/config file and replace the line with :

url = git_user_name@http://server_ip:repo_name.git

to the following:

url = ssh://git_user_name@external_ip:non_standard_ssh_port/repo_name.git

problem using capistrano on deployment server after server ip address change

kosmas — Mon, 27 Jun 2011 12:45:30 +0000

Problem
After changing the IP address of your staging server the cap deploy does not work any more and gives you the following error:

** [192.168.0.50 :: err] Host key verification failed. ** [192.168.0.50 :: err] fatal: The remote end hung up unexpectedly

Solution
You would need to login to your staging server (as your deployment user) and do an initial checkout for one time for the ssh keys to work.
So you could do something like the following:

$ ssh user_name@staging_server $sh -c 'git clone -q git_user@192.168.0.50:repo_name /some/tmp/dir/temp_repo_name

Make sure that you reply ‘y’ to the question about the authenticity of the host as in:
The authenticity of host '192.168.0.50 (192.168.0.50)' can't be established. RSA key fingerprint is xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xxb. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '192.168.0.50' (RSA) to the list of known hosts.

Net delete the newly created git project from your tmp directory, and then you should be able to use cap deploy as normal again from your development pc

capistrano deployment fails after dreamhost server move

kosmas — Fri, 08 Oct 2010 10:27:29 +0000

Problem
You have set up your capistrano recipe for deployment to dreamhost using password less logins, but after dreamhost moves your git repository server to a different server, the deployment breaks, with ‘permission denied’ when trying to get the git repository.

Solution
As the server was moved you would need to copy your ssh public key from the deployment server to the new server again for the password-less logins to work again.
Follow the details here how to copy your public key across, login in once with your password, and after that your capistrano recipe should be working again as normal.

Password – less logins and aliases with ssh

kosmas — Wed, 06 Feb 2008 11:44:54 +0000

Problem
You want to be able to login to different servers with ssh, but don’t want to be using your password every time.

Solution
We assume that you already have installed ssh and have created ssh public keys in your local machine.

Run the following in your local machine:

ssh-copy-id -i ~/.ssh/id_rsa.pub user_name@remote_host

If you want to add aliases in your bash profile so you don’t have to type the whole address of the remote host, edit your .bashrc and add:
```
alias short_name="ssh user_name@remote_host"
```
Restart your X server, or simply start a new terminal session
You should be able to login with ssh without using your password by typing in your command prompt in your local machine:
```
short_name
```
