[jira] [Closed] (GUACAMOLE-435) SSH handshake failing

["Nick Couchman (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/GUACAMOLE-435?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Nick Couchman closed GUACAMOLE-435.
-----------------------------------
    Resolution: Duplicate

Marking this as a duplicate of GUACAMOLE-407, as they both deal with the same issue - missing key exchange and ciphers due to the older version of libssh2 included in CentOS7.

> Opening a SSH session to the same system via Putty works perfectly, so it seems like something about guacd is preventing from successful handshake.
