[Capistrano] Re: Connection failed: NoMethodError: undefined method `ssh_type' for nil:NilClass

I'm guessing there is an entry in your .ssh/known_hosts file that Net::SSH isn't recognizing correctly. You might try backing up that file, and then deleting it, and seeing if that works. If it does, and if you want to preserve your known_hosts file, you'll need to find the entry in known_hosts that is confusing Net::SSH and eliminate it manually.

Hi,

I'm really new at this and could do with some help. I am tunneling my
connection using SSHKeyChain on Mac OS X - this is set up and working
fine for ssh in a termal window.

I've created  deploy file for my hosting company (Site 5) and I'm
trying to run 'deploy:setup' when I get the following messges:

  * executing `deploy:setup'
  * executing "umask 02 && mkdir -p /home/xxxx/apps/dtw1 /home/xxxx/
apps/dtw1/releases /home/xxxx/apps/dtw1/shared /home/xxxx/apps/dtw1/
shared/system /home/xxxx/apps/dtw1/shared/log /home/xxxx/apps/dtw1/
shared/pids"
    servers: ["www.????.com"]
connection failed for: www.????.com (NoMethodError: undefined method
`ssh_type' for nil:NilClass)

My software stack is:
Capistrano v2.0.100
Rails 1.2.3
ruby 1.8.6 (2007-03-13 patchlevel 0) [i686-darwin8.10.1]

My deploy.yml:

set :user, "xxxx"

set :repository,  "svn+ssh://[EMAIL PROTECTED]/home/#{user}/repos/

# This is related to site5 too.
