Summary: Small forwarding DNS server
- Add support for Linux conntrack connection marking.
- Enable support for reading ISC DHCPd lease files
- Enable support for calling scripts when leases change
- Enables built in TFTP server for netbooting
IP Space Migration ContinuesAll Funtoo user containers in the 8.28 IP space will be moving into our new IP space (172.97) over the next few days. If you have DNS set up -- be sure to watch your container and update to the new IP! container.host.funtoo.org DNS will be updated after the move.
Funtoo Hosting IP MoveFuntoo user containers with IPs in the 72.18.x.x range will be gradually migrating to new IP addresses this week. If you have DNS entries for your containers, please be aware that your DNS will need to be updated.
New ARM StagesNew ARM Stages, built with a new toolchain, are now hitting mirrors. Existing ARM users should re-install using these stages (dated Aug 3, 2015 or later,) rather than upgrade using emerge.
As this page deals with DNS it has the potential to break your internet access! Ensure you have stable live media that can restore your system.
Dnsmasq is a dns cache, dhcp, and pxe server. This package is lightweight, and will work well for individual computers, or small lans.
# emerge net-dns/dnsmasq
/etc/dnsmasq.conf is where most of dnsmasq's configuration is done. It's file is well commented, and ready for several scenarios.
place other upstream dns servers in /etc/resolv.dnsmasq.conf with your preferred DNS server at the top of the list. The first console command in the block will wipe out existing /etc/resolv.dnsmasq.conf settings, back them up if you have anything important in them.
# echo "nameserver 126.96.36.199" > /etc/resolv.dnsmasq.conf
... resolv-file=/etc/resolv.dnsmasq.conf listen-address=127.0.0.1
To listen to a DNS server on an alternate port: In this example we'll install dnscrypt-proxy (package not on wiki - please add):
... #resolv-file=/etc/resolv.dnsmasq.conf server=127.0.0.1#2053 listen-address=127.0.0.1
Now your localhost / 127.0.0.1 is your primary DNS to point net connection scripts to. This is the point of no return command. Start the service before you run this, and be prepaired to test with dig that it's pulling up servers through dnsmasq.
# echo "nameserver 127.0.0.1" > /etc/resolv.conf
This is the revert to known working DNS servers command:
# echo "nameserver 188.8.131.52" > /etc/resolv.conf
# rc-update add dnsmasq default # rc
Package:Bind-tools contains dns testing utilities. To verify that dns requests are returned from the local server: emerge bind-tools, then run:
# dig google.com | grep -i server ;; SERVER: 127.0.0.1#53(127.0.0.1)
