SSH connection can fail unpredictably
-------------------------------------
Key: JRUBY-5769
URL: http://jira.codehaus.org/browse/JRUBY-5769
Project: JRuby
Issue Type: Bug
Affects Versions: JRuby 1.6.1, JRuby 1.6
Reporter: Hiro Asari
Assignee: Thomas E Enebo
It is reported in http://www.ruby-forum.com/topic/1441300 that Net::SSH
connections can fail unpredictably.
When it fails, exceptions caught can vary:
{noformat}
Error: OpenSSL::Cipher::CipherError: Input length not multiple of 16 bytes
Error: Net::SSH::Disconnect: disconnected: Packet corrupt (2)
Error: Net::SSH::Disconnect: connection closed by remote host
{noformat}
A stack trace might look like:
{noformat}
OpenSSL::Cipher::CipherError: Input length not multiple of 16 bytes
