aphyr / salticid Goto Github PK

I am getting following issue on Amazon EC2 Linux instance

[ec2-user@bastion-nv ~]$ salticid -l example.rb -h mongo1 hello

Thanks!

This is the first demo example.rb

host '127.0.0.1' do
  user 'localhost'
    task :hello do
      exec! 'ls -la /', echo: true
  end
end

I type salticid -l example.rb -h localhost hello in the command line, but get this

BTW, this is my /etc/hosts

127.0.0.1	localhost
127.0.1.1	UncP

In the readme we write the phrase

Take a look at Jepsen's salticid config: https://github.com/aphyr/jepsen/blob/master/salticid/main.rb

Where should this go?

I ran into this today on a RHEL6 box:

[selena@]$ salticid -s salticid
/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in gem_original_require': no such file to load -- ncurses (LoadError) from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:inrequire'

from /usr/lib/ruby/gems/1.8/gems/salticid-0.9.5/bin/salticid:6
from /usr/bin/salticid:19:in `load'
from /usr/bin/salticid:19

I needed the following packages:

• ncurses-devel
• ruby-devel
• "Developer Tools"

And, I needed to install the ncurses gem.

Is this a doc change, or is adding ncurses to the pre-reqs something you want to do? Or something else?

Hi, first of all, your blog posts are both funny and amazingly informative. They led me to try salticid and jepsen.

I want to run salticid+jepsen with hosts n1 through n5 running in linux containers, but that would require not using port 22 for these hosts, I would think...? If so, I would need to specify ports along with the hosts in the salticid configuration.

Is there a way to do this? Thanks!

Hello,

I am getting an error while trying to run sample examples:

example.rb:8:in load': compile error (SyntaxError) example.rb:6: syntax error, unexpected ':', expecting kEND exec! 'ls -la /', echo: true ^ from /var/lib/gems/1.8/gems/salticid-0.9.5/bin/../lib/salticid.rb:111:ineach'

I am using Debian 6.0.

Hey, this is kind of a meta-issue: With the README prominently displaying a picture of a spider, it might trigger panic attacks on readers with arachnophobia.

You might want to go with a clearly labeled link to an image or a wikipedia article instead.

After all, you'd probably like people to make use of that piece of software you built :)

Hi - first off, thanks for the work on this.

I think there is a dependency missing since I don't see an attempt to install the ncurses gem.

I'm running an Ubuntu 13.04 EC2 AMI and I've apt-get installed ruby 1.9.1 along with rubygems. I did a gem install salticid and when I attempt to run the salticid executable I get this load error message:

# salticid -h 
/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- ncurses (LoadError)
    from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
    from /var/lib/gems/1.9.1/gems/salticid-0.9.5/lib/salticid/interface.rb:3:in `<class:Interface>'
    from /var/lib/gems/1.9.1/gems/salticid-0.9.5/lib/salticid/interface.rb:2:in `<class:Salticid>'
    from /var/lib/gems/1.9.1/gems/salticid-0.9.5/lib/salticid/interface.rb:1:in `<top (required)>'
    from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
    from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
    from /var/lib/gems/1.9.1/gems/salticid-0.9.5/bin/salticid:6:in `<top (required)>'
    from /usr/local/bin/salticid:23:in `load'
    from /usr/local/bin/salticid:23:in `<main>'

I'm sure this might be user-error on my part. I don't know if only Ruby 2+ is supported. But I don't see a wiki and there is no mention in the README (also, I don't see a {{.ruby-version}} file in the repo either).

I see a commit that suggests that the ncurses is a requirement again:

d1b8262

Unfortunately, I can't get the ncurses gem to build right now. I'm working on that.
