ssh from a Solaris machine to a -current server

[Chavdar Ivanov <ci4ic4%gmail.com@localhost>]

Hi,

Perhaps a newbie question - with the latest updates to ssh I've lost the capability to ssh from a Solaris 10 (or OpenIndiana) host to a NetBSD-current server:

- from an old Solaris 10 machine:

[srv1] / # ssh support6

no kex alg

- from an OpenIdiana (latest hipster):

ci@uksup4:~$ ssh xci@support6

no common kex alg: client 'diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1', server 'curve25519-sha256%libssh.org@localhost,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1'

The clients are: 

 % ssh -V

Sun_SSH_1.1, SSH protocols 1.5/2.0, OpenSSL 0x0090704f

and

ci@uksup4:~$ ssh -V

Sun_SSH_1.5, SSH protocols 1.5/2.0, OpenSSL 0x100010af

It still works fine from an Oracle Solaris 11.2 host: 

landisk% ssh -V

Sun_SSH_2.2, SSH protocols 1.5/2.0, OpenSSL 0x1000108f

Is there anything I can do (short of installing openssh) on these?
