    Hi everyone, I'm using hudson on a linux machine (tethys) without any problem. I want to distribute a build to another linux machine (calypso) with the same configuration (in fact, copy/paste of the VM in a vmware server). But When I want to start the slave (calypso) with the ssh configuration, I've this log : [08/29/08 15:04:20] [SSH] Opening SSH connection to calypso:22.
