Occasionally I've seen issues with Joyent smartmachines (= Solaris zones) where SSH stops working, even though SSH is still listening.

An ssh attempt then looks like this:

ssh root@10.0.32.50
ssh_exchange_identification: Connection closed by remote host

To solve this issue, the SMF service "smartlogin" needs to be restarted on the physical server on which this smartmachine resides.

[root@computenode003 ~]# svcadm restart svc:/smartdc/agent/smartlogin:default

 The SSH login into the smartmachine should then work again:

ssh root@10.0.32.50
Last login: Fri Jan 31 08:51:36 2014 from xxx.xxx.xxx.xxx
