Hi Yvan, Good news for the 25 servers, thanks! Direct ssh, , key authentication based, access from ccage to the 25 machines would be the simpler option. If not possible, I think that having ssh access, using ssh key authentication, from ccage to the 3 build nodes is enough. And then we would need to have ssh access from the 3 build nodes to the other 23 machines, using ssh key authentication, Cheers, Fabrice On 01/23/2015 04:43 AM, Yvan Calas wrote: > Hi Fabrice et al., > > Could you tell me if you have strong requirements concerning the network connectivity of the new (25) qserv servers?
