I don't have a directory /etc/sysconfig/networking/ on my CentOS-7 server, but I have IPV6INIT=no in /etc/sysconfig/network-scripts/ifcfg-enp{23}s0 . Incidentally, I haven't yet worked out how to get any useful information from nmap, as suggested by Johnny Hughes - I only get information about open ports, which is interesting but not relevant to my query about the 169.254.* address appearing in "arp -a" on my server. I looked at "man nmap" but there seem to be an infinity of options. -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx https://lists.centos.org/mailman/listinfo/centos
