Not a chance, AFS uses RX for the rpc traffic, Coda uses RCP2/SFTP. Even if you'd (manage to) replace the transport layer, the whole upper layer interfaces are completely different. Coda servers have to provide additional information, like version-vectors, so that clients can detect replication and disconnected operation related conflicts. Then there is the fs operation logging, (trickle)reintegration, resolution, which all do not have an AFS equivalent. Also I believe, AFS currently handles its cache on a block granularity, while Coda has file-based granularity, which allow us to make certain consistency guarantees. > o We have an existing Kerberos V realm in place.

There is an unexportable patch, which allows a user to get a Coda token without typing a password if he is Kerberos authenticated. > o If using Kerberos V authentication, can we use Kerberos keytab files > to obtain tokens? (this ties into the previous question) Likely, I haven't tried. > o How difficult is it to port AFS-aware code to work with Coda? Is > the API similar, or is it another beast altogether? It depends on what it is aware of, I never heard of this, probably because I never asked :) JanReceived on 1999-09-14 10:08:02
