Maybe not "necessary", but at least in the past it was possible for fileserver -> client communication to occur several hours after the last client -> fileserver communication. Jaap Winius found this by experimenting with the port mapping timeouts on his equipment: <https://lists.openafs.org/pipermail/openafs-info/2011-May/036014.html> The reasoning I think I had for that (it's somewhere in there) was that various probes only happen when we have callbacks recorded for a particular client or fileserver. With no callbacks, no probes occur, so we can go a long time without any communication. And even with no callbacks, there are a few situations where a fileserver can try to contact a client again. I haven't looked at this area in a long time, though; I may have that wrong. This situation should be better now than it was when that thread was made. But I'm just mentioning that to show that the idea of hours-long-mappings is not unheard-of. -- Andrew Deason [email protected] _______________________________________________ OpenAFS-info mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-info
