I have updated the rtadvd patch to allow greater flexibility in configuring
DNS servers and search domains in rtadvd.conf.
The new patch allows comma-separated values in the "rdnss=" and "dnssl="
entries and now sends separate RA RDNSS and DNSSL options for each such
entry. This allows separate lifetimes to be given for each RA option.
Previously,
:rdnss="2001:db8:ffff::1":rdnss0="2001:db8:ffff::2":\
:rdnssltime#1200:
sent one RA RDNSS option containing two server IPs with the one lifetime.
Instead, you can now say:
:rdnss="2001:db8:ffff::1,2001:db8:ffff::2":rdnssltime#1200:\
:rdnss0="2001:db8:ffff::3,2001:db8:ffff::4":rdnssltime0#900:
which will send two RA RDNSS options, each with two server IPs and each
with the corresponding lifetime.
Same goes for "dnssl=".
I now also send RA RDNSS and DNSSL options with zero lifetimes when the
server is shut down using a TERM signal.
If you've tried this out and wish to grab this latest version, all you
need is the rtadvd-rdnss.diff update from the web site. The other three
diffs do not change.
