Sorry, but that is not correct. NetworkManager can handle split-dns just fine, by using dnsmasq and reconfiguring it via dbus when vpn connections come and go. I can easily add more servers + zones by dropping a config file snippet into the /etc/NetworkManager/dnsmasq.d/ directory, for example to resolve the hostnames for my kvm guests on the libvirt network. That works for ages on my RHEL-7 workstation where systemd-resolved doesn't even exist ... > So sending the requests to all available DNS servers in absence of > better routing info is a great enabler: I fail to see why sending queries to all servers is a good plan. The redhat vpn dns servers surely can't resolve the hostnames for my local lan, and frankly they shouldn't even know which hosts I try to access. Likewise my ISP shouldn't know which non-public RH servers I try to access. > Key, take-away here: > > 1. Ideally we'd just route company DNS traffic to VPN, and everything > else to local LAN DNS.

At the expense of leaking information, which I don't consider a good trade-off. take care, Gerd _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org
