Andrew Kutz seems unstoppable and continues to release useful plug-ins for the new VMware VirtualCenter 2.5 architecture.
After one to manage Storage VMotion migrations and one to manage mass configuration of port groups, the last creation allows to embed a SSH client in the VirtualCenter GUI.
To realize this plug-in Andrew used SharpSSH, a SSH2 library for Microsoft .NET Framework, and ackterm for VT-100 emulation, but he has yet to implement the Public Key authentication.
Just like the others, this tool is totally unsupported by VMware and should not be deployed in production environments.
