I'm not quite sure if you're asking what you as a person should do, or if you're asking what the code does. If you mean what IPs you should be specifying in various places, you should put in the 'public' IPs that are always reachable by everyone. That means put that in CellServDB and probably the fileserver NetInfo. If you put a 'private' IP in there, then clients accessing from elsewhere may also see that IP, and obviously they won't be able to connect. We don't really do "split-horizon"-style setups, since everyone gets the same list of IPs for fileservers. > If you just want to see where the traffic is > > going, capture some net traffic.

Yes, tcpdump or wireshark are the usual tools. wireshark is/can be graphical and probably more intuitive if you haven't used similar tools before. -- Andrew Deason [email protected] _______________________________________________ OpenAFS-info mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-info
