It looks like something broke recently that severely limits the MTU in Fedora 20 when running under NM. Are other people seeing this too? Here I'm pinging my upstream lan-to-wan gateway. A 1200 byte ping fails while a 500 byte one succeeds. I see the same thing when pinging between two identical, fully up-to-date f20 systems. wolfgang@arbol ~]$ ping -s 1200 gw PING gw.wsrcc.com (192.168.35.1) 1200(1228) bytes of data. ^C --- gw.wsrcc.com ping statistics --- 3 packets transmitted, 0 received, 100% packet loss, time 2000ms [wolfgang@arbol ~]$ ping -s 500 gw PING gw.wsrcc.com (192.168.35.1) 500(528) bytes of data. 508 bytes from gw.wsrcc.com (192.168.35.1): icmp_seq=1 ttl=64 time=0.503 ms 508 bytes from gw.wsrcc.com (192.168.35.1): icmp_seq=2 ttl=64 time=0.460 ms 508 bytes from gw.wsrcc.com (192.168.35.1): icmp_seq=3 ttl=64 time=0.456 ms 508 bytes from gw.wsrcc.com (192.168.35.1): icmp_seq=4 ttl=64 time=0.454 ms ^C --- gw.wsrcc.com ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3001ms rtt min/avg/max/mdev = 0.454/0.468/0.503/0.025 ms [wolfgang@arbol ~]$ -wolfgang -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx 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?
