[Capistrano] How to deploy with SSH from Windows?

[Masuda]

Hi,there.
I'm trying to deploy with Capistrano 2.5.5 and git.
But when using "cap deploy" command, server requires password for
Windows login user name, permission denied and tries to roll back.
I set ssh public key and deploy.rb with ssh_options.

Command prompt is below.
--------------------------------------------------------------------------------------------------------------------------------

ssh_options[:keys] = %w(~/.ssh/id_rsa.pub)
ssh_options[:port] = 22
ssh_options[:forward_agent] = true
--------------------------------------------------------------------------------------------------------------------------------

I'm trying these 3days but I can't yet...
Please give me advice!!

I'm not good at english because I'm Japanese.
So, please be patient with me.
Regards.

Di you have an SSH key, and is it at %w(~/.ssh/id_rsa.pub) ?

What SSH client are you using ?

Thanks for reply.

> Di you have an SSH key, and is it at %w(~/.ssh/id_rsa.pub) ?

Yes I have a SSH key but I made a mistake.
It is at "~/.ssh/authorized_key"
so　I collected it %w(~/.ssh/authorized_keys).

> What SSH client are you using ?

I thought that no SSH client needed, so just command prompt only.
And then I did deploy command with Pagent.

Command prompt are below.

Password requirements without Windows login name, Password:,
disappeared.
But yet it requires password for Windows login user name and new
errors occurred.
I have no idea.

[Lee Hambley]

I'm not familiar with a windows installation, since Net::SSH is a pure-ruby implementation of an SSH client, there shouldn't be one required.... if you are deploying *to* windows that isn't going to work very well for you... looking at the logs, you aren't entering a valid password for the target computer, that is more of a configuration issue, if the remote host is Windows based, running an open SSH server, then you need to ensure you can SSH to it manually, you can read an example of how to test that using Net::SSH here: http://net-ssh.rubyforge.org/ssh/v2/api/index.html -

The server which I want to deploy is not windows.
It's Linux, CentOS 5.2 .

Now I realized that when I using command "cap deploy:setup"
it doesn't require password for Windows login user name but requires
root user password, not authorized public key.
Though it went well. I confirmed directories were made.

And comment out "set :scm, :git" for test, of course it couldn't
deploy well, but command finished and doesn't require password for
Windows login user name.

So, it seems that this problem occurs when using git, not Windows.
I found past similar problem.
http://www.mail-archive.com/capis...@googlegroups.com/msg05494.html
quote:
Both 'user' variables are set to 'rails-app-user' in deploy.rb:.
But Capistrano 2.5.3 keeps using my local username to log into the
server. [OS X Leopard, 10.5.5.]
This problem seems unsolved.

What should I do?

[Masuda]

I fixed the password problem.
It is caused using git without "PLink".

I re-installed Git (msysgit) "Use Plink" on Coosing SSH executable step.
Then, the problem which require password for Windows login user name fixed.

But ... access denied and got a fatal error.

What's wrong?

[Lee Hambley]

your server has locked you out ? .. can you SSH in with a net-ssh test script ?

I guess you want to setup passwordless login from a windows computer to
any ssh server.
Here's how to go about it:

Get the id_rsa.* files for your keys and copy them to /Documents and
Settings/<username>/.ssh
Be advised that there is no way to create a .ssh (watch the '.' at the
start) from windows explorer, you will have to open a command window and
use mkdir.

The key in you id_rsa.pub should be added to the authorized keys file of
your server.
I initially had a bit of trouble getting cap to see the keys so I had to
add a couple of lines in my capfile. Also because it's for work I use a
different pair of keys than privately so I renamed the _rsa files:

ssh_options[:paranoid] = false
if File.exists?("#{ENV["USERPROFILE"]}/.ssh/other_rsa")
ssh_options[:keys] = "#{ENV["USERPROFILE"]}/.ssh/other_rsa"
end
ssh_options[:forward_agent] = true

Cheers,
V.-

Thanks for replies.

Capistrano SSH key authentication seems to be going well, because cap
deploy:setup command was finished and I confirmed directories were
created.
Perhaps the problem is "git" SSH key authentication.
I had investigated by myself but not figured out yet how to config git
for SSH key authentication.

Where is your Git repository hosted?

[Masuda]

My Git repository is VPS,remote hosted.

I fixed the problem which got a message "Access denied".

It was deploy.rb and pageant which caused.
I did below.
1.deploy.rb

set :repository, "ssh://remote.host.address:22/var/git/#{application}.git"
　↓

set :repository,
"ssh://ro...@remote.host.address:22/var/git/#{application}.git" #add
"root@"

2.I found that pagent does not save SSH keys, so added keys.

Then SSH key required and "Access denied" didn't show.

But... I got an another error "ssh_exchange_identification".

Command prompt messages are below.
