Hi all,

recently we've moved from OpenSSH 6.2 to OpenSSH 6.6. Since we moved we 
have got problems with some sftp connection.

When we connect to some hosts we receive this error:

DH_GEX group out of range: 1536 !< 1024 !< 8192 
Couldn't read packet: Connection reset by peer 

Our OS is:  SUSE Linux Enterprise Server 11 SP4 

We've read that is a known issue: 
https://www.novell.com/support/kb/doc.php?id=7016904

We've tried to use this workaround: put in /etc/ssh_config this line:

KexAlgorithms 
diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1,diffie-hellman-group1-sha1 


It works for some sftp connection, but not all.

Can you help us ? Can you explains us why some connection work and other 
not ?

Kind regards,
Alessandro Lomonaco
