I can’t get past the setup step in Capistrano. I know the paths are
correct and I’m using zsh locally (bash on remote), so the shell
shouldn’t be a problem. It never asks for the SSH password, even. Any
help you could give would be greatly appreciated. Thanks.

Kenneth,
What error are you getting? What is the command-line you are using to
run the setup?
I’m not getting any explicit error. It just hangs at the " * executing
“mkdir -p -m 775” line. This is with “rake remote:exec ACTION=setup”
and “cap setup”.

Strange… Could you try adding the following to your deploy.rb:
ssh_options[:verbose] = :debug
Then run it and capture the output to a file. Search and replace any
instances of your password (if any), and then email the result to me
directly.
Thanks! Sorry for the snafu… Hopefully this dump will enlighten me
a bit about what is going on.

One more data point: I just upgraded to Cap 1.1. Everything worked
great until running “cap -A .”
[root@zvents dev_instance]# cap -A .
exists config
Then it just sat there for a couple minutes. It turns out that it never
displayed the “overwrite config/deploy.rb? [Ynaq]” prompt, but it was
waiting for a keystroke. I hit enter and then it displayed the prompt
after the fact. Odd. In case it matters, this is with termios 0.9.4
gem on CentOS 4.0.
Apart from that, everything works great.
I can’t get rake remote:exec ACTION=setup to complete successfully. I
suspect there is a problem in authentication.
I connect to my development server using RSA authentication and I am
using keychain, (v2.02) an ssh-agent front-end so I only have to
enter a passphrase for my key once.
http://www.gentoo.org/proj/en/keychain/index.xml
Keychain is an OpenSSH key manager, typically run from
~/.bash_profile. When
run, it will make sure ssh-agent is running; if not, it will start
ssh-agent.
It will redirect ssh-agent’s output to ~/.keychain/[hostname]-sh, so
that cron
jobs that need to use ssh-agent keys can simply source this file and
make the
necessary passwordless ssh connections. In addition, when keychain
runs, it
will check with ssh-agent and make sure that the ssh RSA/DSA keys that
you
specified on the keychain command line have actually been added to
ssh-agent.
If not, you are prompted for the appropriate passphrases so that they
can be
added by keychain.
I have not used capistrano before and have installed the most recent
gem on my development machine and the single machine handling :web
and :app (the database is on a separate machine altogether).
Here’s what happens when I run the task:
$ rake remote:exec ACTION=setup

/usr/local/lib/ruby/gems/1.8/gems/capistrano-1.1.0/lib/capistrano/recipes/standard.rb

Weird! What is your rails version?
Stephan,
The telling error here is this:
No such file or directory - /tmp/ssh-G0tW2k3sTa/agent.333
If your ssh-agent is configured properly, it will create a socket and
then set an environment variable called SSH_AUTH_SOCK that gives the
path to the socket.
However, things do go wrong. It sounds like you’ve got the
SSH_AUTH_SOCK environment variable set, but it is pointing to a
socket that doesn’t exist. Try unsetting the SSH_AUTH_SOCK
environment variable before running capistrano and see if that helps.

Thanks for responding Jamis,
I unset SSH_AUTH_SOCK and no longer have the “No such file …” error.
After killing ssh-agent and running kechain again I now have an
SSH_AUTH_SOCK that points to something valid.
I had turned off rsa authentication (by renaming the server folder
.ssh), had the same problem and have turned it back on. However
everytime I run my task I get asked for the password (I’m not sure why
it isn’t using the host keys).
Here’s what I see if I try the task with --trace, basically the process
ends by raising AuthenticationFailed.

I’m not 100% sure, but probably not. Net::SSH is a SSH2 client–it
doesn’t support SSH1.
Jamis,
Does Net::SSH work with SSH protocol version 1 RSA keys? That is what
I have been using.
I’ve generated both DSA and RSA SSH protocol level 2 keys but haven’t
yet got them to work with the remote server using ssh shell login.
I’ve copied the id_rsa.pub key identity.pub on the remote host and
copied id.rsa into identity on the local host.
The Net::SSH connection method works fine using a password but not
with the original RSA1 keys.
require 'net/ssh
session = Net::SSH.start( ‘maggie.concord.org’, ‘sbannasch’, ‘#########’
)
session = Net::SSH.start( ‘maggie.concord.org’, ‘sbannasch’ )
So originally, I had the same problem - when running ‘cap deploy’ I got
a
No such file or directory - /tmp/ssh-XEpLf2881/agent.2881
Then I followed the helpful advice in this forum and unset my
SSH_AUTH_SOCK, which successfully got rid of the initial error.
Unfortunately, another one replaced it. I now get “exception while
rolling back: Errno::ECONNREFUSED, Connection refused”. Any help with
this would be much appreciated, as I really don’t know how to go about
debugging issues with SSH. Below is the full output.
