Hi,
When trying to ssh login, to a host which has been reinstalled, using:
Net::SSH.start( value_hosts, USER, :password => PASS , :paranoid =>
false, :forward_agent => true ) do|ssh, err |
I am getting an error:
/sw/lib/ruby/gems/1.8/gems/net-ssh-1.1.1/lib/net/ssh/host-key-
verifier.rb:47:in `process_cache_miss’: fingerprint da:
34:2e:a6:87:c4:c8:49:0e:a1:8e:39:fd:fc:ef:e7 does not match for (Net::SSH::HostKeyMismatch)
Is there a way to Ignore HostKeyMismatch ?
Net::SSH.start( value_hosts, USER, :password => PASS , :paranoid =>
false, :forward_agent => true ) do|ssh, err |
is not working, i.e the :paranoid => false does not seem to work.
Any hint will be appreciated.
What i am trying to accomplish is to login via ssh, even of the ssh
exchange key is no longer valid since the OS was reinstalled.
i found the following, post but even that does not work:
in order to resolve the HostKeyMismatch, use following in irb:
require ‘rubygems’
require ‘net/ssh’
include Net
Net::SSH.start( ‘10.5.30.52’, ‘root’, :password => ‘password’ ,
:paranoid => false ) do|ssh|
#puts “hello”
end
rescue Net::SSH::HostKeyMismatch => e
puts “remembering new key: #{e.fingerprint}”
e.remember_host!
retry
end
i get an error:
irb(main):001:0> Net::SSH.start( ‘10.5.30.52’, ‘root’, :password =>
‘password’ , :paranoid => false ) do|ssh|

Maybe IRB bug!!
