Re: VPN

Sorry for the delay. I was out.

VPN is a technology we use in our lab since a year. It is just a technique
to segment and control networks. It is a technology more subtle than
subnetworking but it does not change the philosophy.

For instance people dialing directly to our modems belong to a VPN with
some extended controls: you need a certificate to be identified. Then you
have access to all resources of the lab, including to IUCr journals since
you are recognized as a legitime meber of the lab. Connecting to the lab
throu a FAI and through our firewall does not give' that right since you do
not belong to a VPN of the lab. Thus there is no problem for access to the
journals.

Regards.
