PS. one option is to add something like postfix's "protocols = [ipv4|ipv6|all]" to yum.conf and let sysadmin fix it. |

That option exists. ip_resolve={4|6] see man yum.conf for more detail and the other new options. |

Great. When all else fails I'll read man yum.conf... Seriously, though, thank you and apologies for the noise. |

Also, if you really don't need IPv6 on that machine, it's much better to disable it at the kernel level with ipv6.disable=1 on the kernel command-line (e.g. by adding it to /etc/default/grub and running grub2-mkconfig afterwards). This way the whole IPv6 stack is disabled, you get more memory for your applications and your networking activities a bit faster since there is no dual network stack -- a total win for an IPv4 system, in my opinion :). Oh, and you don't need to touch configs to instruct yum to use IPv4 only in this case :))) |

True, but that happens after you got used to systemd, grub2, nmtui, unfsck'ed the network after removing avahi, and dust has settled in general. ;-) Thx |
