#3271: Cannot connect with SFTP

 Priority:  high                |   Milestone:         
Component:  sftp                |     Version:  3.2    
 Severity:  major               |    Keywords:         
 After a recent patch was applied to our Solaris 10 software on our server,
 we can no longer connect to the server with Cyberduck using SFTP. Upon
 login, it immediately gives a, "I/O Error: Connection failed. There was a
 problem connecting to our server:22". Nothing is even listed in the

 In /var/adm/messages we are getting:
 fatal: matching cipher is not supported: aes256-ctr

 We are able to connect to the same server successfully using Fetch and
 Fugu. We are running SSH2.

 Do we somehow need to reconfigure Cyberduck to handle a different cipher
 or to use SSH2 or ...?

 We are running Mac OS 10.4.11 and 10.5, and Cyberduck Version 3.2 (4648)
 or later.
