Re: [capistrano-mailing-list] Trying to write a task to distribute files from a remote server to a group of other remote servers
Thanks for the response. Can SSHkit be installed (I'm not the sysadmin) without breaking the existing Cap v2 installation? We have a lot of stuff depending on the latter.

SSHKit belongs on the client machines driving the SSH connection, not on the servers to which you connect. If you're running SSHKit *on* a server, along side Capistrano (also not typically installed on servers) then it'll be fine. Various versions of Capistrano 3 have various requirements on various version of SSHKit, but Capistrano two is unaware of SSHKit and it will not interfere.

Re: [capistrano-mailing-list] Trying to write a task to distribute files from a remote server to a group of other remote servers
I'd drop Capistrano and use SSHKit, the underlying driver in Capistrano v3
(your example is v2) - see
https://github.com/capistrano/sshkit/blob/master/EXAMPLES.md#upload-a-file-from-disk
and
https://github.com/capistrano/sshkit/blob/master/EXAMPLES.md#using-with-rake
Combine those two to recreate what you have above, and mix in some
https://github.com/capistrano/sshkit#tunneling-and-other-related-ssh-themes
to make sure that you can reach the hosts as you need to, and I think
you'll be fine.
SSH is probably hanging because your process is hanging onto some
resources, that can often be solved by tunneling and/or remotely starting
thigns with `ssh me@thehost 'thecommand'`, for example. Hard to say without
more info.
But, I'd absolutely avoid using Cap v2 if you're starting out, it's more
than two years since EOL, but very widely documented/blogged about in the
net.

I'm trying to write a task (to be called from a Perl script) that will
work on any Linux host in my environment. However, since there is only one
host that can SSH to every other host (it can also receive SSH connections
from any host), and I can't guarantee that the task will be running on that
host, I need to find a way to run the task on that host.
Here's what I came up with so far:
set :user, usr
cmd = getpass + user
set :password, `#{cmd}`
task :distribute, :on_error = :continue do
host_list = hosts.split(',')
servers = []
host_list.each do |n|
servers.push([n])
end
filelist=files.split(',')
filelist.each do |f|
upload f, target_dir, { :via = :scp, :hosts = servers, :on_error =
:continue }
end
end
to be invoked like this:
/usr/bin/cap -f distribute_file.rb -S usr=user_to_run_as -s
target_dir=/path/to/target -s files=/path/to/source_file -s hosts=(list of
hosts) HOST=master_host
but that caused it to only run against master_host
So then I tried executing it with SSH, but that had a tendency to hang,
plus it seemed to me like there should be a built-in method for this.
I'm a Perl guy and am new to both Ruby and capistrano, so please be gentle
:)
Thanks.
