hostList.each do |h| Net::SSH.start(h, "user", :password => "password", :timeout => 10) do |ssh| end end
However, my test script kept dying at various points due to issues with the ssh connection to specific servers.
Naturally I thought of wrapping the Net::SSH.start call in a begin/rescue/end but couldn't for the life of me find any information about the exceptions that the start method could throw. Finally after a bit of digging on google I came across this page which details them rather handily :-) In short, here's how I have it wrapped now:
hostList.each do |h| begin Net::SSH.start(h, "user", :password => "password", :timeout => 10) do |ssh| end rescue Timeout::Error puts " Timed out" rescue Errno::EHOSTUNREACH puts " Host unreachable" rescue Errno::ECONNREFUSED puts " Connection refused" rescue Net::SSH::AuthenticationFailed puts " Authentication failure" end end
This works fabulously since I don't really need to handle the exceptions but would like to know about them.
