Andrew C commented on SSHD-211:
-------------------------------

I should note that, after this change, I'll be able to implement a custom service \
using existing message types.  A second round of changes would be required to allow \
custom message types - SshConstants.Message is an enum.  
> Allow custom server services
> ----------------------------
> 
> Key: SSHD-211
> URL: https://issues.apache.org/jira/browse/SSHD-211
> Project: MINA SSHD
> Issue Type: Bug
> Affects Versions: 0.8.0
> Reporter: Andrew C
> Attachments: sshd-service-wip.patch
> 
> 
> I'm implementing a custom server/protocol over sshd but to do it I'm extending / \
> modifying the existing ServerSession when instead I should be adding a custom \
> service to the existing ServerSession. Attached a work-in-progress that is \
>                 sufficient to illustrate the basic theory (but not much more):
> - add a Service interface
> - add a ServiceFactory to SshServer that instantiates a Service given its name \
>                 (e.g., "ssh-userauth" or "ssh-connection")
> - implement UserAuthService (ssh-userauth) and ConnectionService (ssh-connection) \
>                 using code extracted from *Session
> - add a currentService to ServerSession and set it when it receives \
> aSSH_MSG_SERVICE_REQUEST and then pass messages along to that (the UserAuthService, \
> once completed, does the same thing with its requested service)
