The problem turned out to be my switch dying in a funny way. When I moved the computer's ethernet from the switch (Netgear GS108E-100NAS) to a spare port on the gateway, large pings started working.

The observation that it wasn't a general fedora problem helped a lot. -wolfgang -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
