The end user seldom have control over all firewalls... There are two goos solutions to this problem, one is to start using TCP for AFS as these problems are solved in good TCP implementations. The other solution is to look at how a good TCP implementation handles path mtu discovery, including black hole detection (when the wold fragment icmp packets are dropped) and copy that. _______________________________________________ OpenAFS-info mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-info
