matching cipher is not supported: aes256-cbc

ssh failed after 141742-01/02 patch on solaris 10 !

enabled aes192/aes256 support in ssh/sshd does not work on S10u3 or older released

A workaround is to disable the use of aes192/aes256 ciphers for ssh and sshd. Change the two config files /etc/ssh/ssh_config and /etc/ssh/sshd_config and add the following line:

Ciphers aes128-ctr,aes128-cbc,arcfour,3des-cbc,blowfish-cbc

You’ll have to restart sshd to pickup the change (“svcadm restart ssh”).
