Apologies for my slightly rude remarks about your document. I shall read it again with more diligence. But I have more or less decided to put IPv6 on the long finger. I'm actually running Centos-5.2 on my server, with shorewall, and it seems that shorewall6 is unlikely to be supported until Centos-6 comes out. I don't want to run iptables directly, as I am not confident that I would get it right; and I don't know of any alternative to shorewall which is available under Centos and which supports IPv6. > The YYYY part of the address in the radvd.conf is the address for the > net-block that your upstream ipv6-capable ISP (or ipv6 tunnel broker) > assigned to you. OK, I'll try putting that in. At present radvd fails, with the error message: helen radvd[4958]: IPv6 forwarding seems to be disabled, exiting -- 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
