Try this: traceroute www.globus.org If you get lots of timeouts, you may need to use ICMP packets, but for some weird reason, that requires root. (I do it often enough that I've set suid on /bin/traceroute but I'm not suggesting anybody else do that.) If the above gets complaints, use this instead: su -c 'traceroute -I www.globus.org' Will show you how close you're getting and if there's any routing problems. I used su -c because I *don't* use sudo on my home machine and don't expect anybody else to either. YMMV, and if you're more happy with sudo, substitute as needed; it's your machine, not mine. Once you've documented where the issue is, call your ISP and let them deal with it because that's what you're paying them for. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
