Solaris Secure Shell Enhancements in the Solaris 10 Release
Since the Solaris 9 release, the following changes have been introduced to
Solaris Secure Shell:
- Solaris Secure Shell is based on OpenSSH 3.5p1. The Solaris implementation also includes features and bug fixes from versions up to OpenSSH 3.8p1. 
- The default value of X11Forwarding is yes in the /etc/ssh/sshd_config file. 
- The following keywords have been introduced: - GSSAPIAuthentication 
- GSSAPIKeyExchange 
- GSSAPIDelegateCredentials 
- GSSAPIStoreDelegatedCredentials 
- KbdInteractiveAuthentication 
 - The GSSAPI keywords enable Solaris Secure Shell to use GSS credentials for authentication. The KbdInteractiveAuthentication keyword supports arbitrary prompting and password changing in PAM. For a complete list of keywords and their default values, see Keywords in Solaris Secure Shell. 
- The ARCFOUR and AES128-CTR ciphers are now available. ARCFOUR is also known as RC4. The AES cipher is AES in counter mode. 
- The sshd daemon uses the variables in /etc/default/login and the login command. The /etc/default/login variables can be overridden by values in the sshd_config file. For more information, see Solaris Secure Shell and Login Environment Variables and the sshd_config(4) man page.
