Configuring Solaris "sshd / ssh daemon” cipher capabilities to match for CA PAM defaults. 


Tested with the versions of CA PAM (4.2 and 4.3) and Sun Solaris (10 and 11)


Unable to connect to the remote SSH host: The socket is EOF


To enable Solaris sshd to accept default CA PAM used ciphers you need to update the Solaris sshd configuration.

The below samples are working for Solaris 10 and Solaris 11.

The default “ciphers” supported out of the box by Solaris 10 and 11 are:

Ciphers aes128-ctr,aes192-ctr,aes256-ctr,arcfour128,arcfour256

These are not part of the default sshd configuration file /etc/ssh/sshd_config

To now add the required CA PAM used session Ciphers (3des-cbc and blowfish-cbc) the sshd setup needs to be updated adding these additional Ciphers. This requires adding the Ciphers to the file /etc/ssh/sshd_config. The result will look like the following with the default Ciphers plus the CA PAM Ciphers:

Ciphers aes128-ctr,aes192-ctr,aes256-ctr,arcfour128,arcfour256,3des-cbc,blowfish-cbc

Once the Ciphers are added the “sshd” needs to reload the configuration data, do this per “root” running command:

svcadm restart ssh
