From Bugzilla Helper: User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.4.2-2 i586) Description of problem: Anaconda, when creating the /etc/hosts file on lines 857-887 does not add the IPv6 addresses for localhost, the local net, the multicastprefix and the all nodes, all routers and all hosts multicast addresses. Oh, it also doesn't seem to close the file... How reproducible: Always Steps to Reproduce: 1. Install Red Hat Linux 7.1 2. Look in /etc/hosts Actual Results: I found a 4 line file with the lines # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost 212.26.207.40 xos040.xos.nl Expected Results: I should've found a file with the lines: # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost 212.26.207.40 xos040.xos.nl ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ff02::3 ip6-allhosts Additional info:
We don't currently configure IPv6 in the installer, so setting it up in /etc/hosts wouldn't make much sense. I'm deferring this issue for a future release.
IPv6 is enabled nowadays by default.
