I found in the end - probably due to something you said - that the problem was entirely due to the fact that I had omitted the line #INTERFACE SOURCE ADDRESS PROTO PORT(S) eth0 eth1 in /etc/shorewall/masq . Since I put it in, and re-started shorewall, everything is working fine. > Timothy Murphy <gayleard <at> eircom.net> writes: > >> ... >> [tim <at> helen ~]$ route -n >> Kernel IP routing table >> Destination Gateway Genmask Flags Metric Ref Use >> Iface ... > This is your backup server (Fedora 13). > First question I have: where did these come from ? > >> 169.254.0.0 0.0.0.0 255.255.0.0 U 1002 0 0 >> eth0 >> 169.254.0.0 0.0.0.0 255.255.0.0 U 1003 0 0 >> eth1 Nb My iptables data presumably all comes from shorewall. I see this address is mentioned in shorewall (in /usr/share/doc/shorewall*/Samples/two-interfaces/ , which I followed). Isn't it used in some way if one's internet connection is down? >>From /etc/resolv.conf I see you obtain your data by NetworkManager for >>both > interfaces eth0 and eth1 (there are no other interfaces, except lo). > Do you know anything about them or their purpose ? > > I would like to see lease data obtained by NM for both interfaces. > Give me outputs: > $ ps aux |grep -i net > $ ps aux |grep -i dhc Actually, I had to stop NM with this OS, and use the network service instead. I'm not sure why. But the network service seems to work fine, and this is only a backup OS, so NM's failure doesn't really matter. -- 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 -- 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
