I've been playing with ipv6, and can use it externally thanks to a tunnel from sixxs.net . But I'm puzzled about its use inside my home network. What are the ipv6 addresses of the machines on this LAN? Are they the ipv6 addresses given by "ifconfig -a"? Or are they modifications of the "local address" given me by sixxs? I should say that the question is theoretical at the moment, as I am running Centos-5.2 and shorewall on my server, and it seems I have to wait until shorewall6 comes along for Centos, which apparently needs a more recent kernel and iptables than currently running under Centos, according to <http://www.shorewall.net/IPv6Support.html>. But I'd like to be prepared for the happy day. I find that at present I can ping6 from any laptop to itself using the ipv6 address from ifconfig -a: ------------------------------------- [tim@mary ~]$ ping6 -Ieth1 fe80::240:f4ff:fe4d:608a PING fe80::240:f4ff:fe4d:608a(fe80::240:f4ff:fe4d:608a) from fe80::240:f4ff:fe4d:608a eth1: 56 data bytes 64 bytes from fe80::240:f4ff:fe4d:608a: icmp_seq=0 ttl=64 time=0.058 ms ------------------------------------- But I cannot ping6 from one machine to another: ------------------------------------- [tim@helen ~]$ ping6 -Ieth1 fe80::202:2dff:fe21:3c9 PING fe80::202:2dff:fe21:3c9(fe80::202:2dff:fe21:3c9) from fe80::240:f4ff:fe4d:608a eth1: 56 data bytes ping: sendmsg: Operation not permitted ------------------------------------- I assume that shorewall is preventing this. Incidentally, I didn't find any online documentation giving much help with IPv6 under Fedora and/or Centos; all the ipv6 documents seemed aimed at someone very different to myself. -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
