Citeren Christian Schoenebeck :
For some (good) reason you decided to remove wget from BusyBox and
replace it by uclient-fetch.
Why not also remove nslookup from BusyBox.
- If compiled with musl it malfunction with given dns-server
Correct. It will completely ignore the [SERVER] argument from nslookup
[HOST] [SERVER] (see [1] & [2]). Either nslookup.c from BusyBox should
be changed to allow overriding the list of nameservers from
/etc/resolv.conf (which are the only ones used with the musl library)
or patched to allow this argument only when compiled against a library
that actually supports this. I have little hope that musl can be
convinced to make such functionality available. Note that in many
cases one can workaround this issue by creating a new /etc/resolv.conf
with the nameserver(s) to use. By default dnsmasq will not use this
file, so this will only influence resolving locally (not on clients
connected).
- use hostip package instead. Tiny and functional
It's not as big as bind-host, but I wouldn't call it tiny either (on
ar71xx at least). The hostip package (~30k) requires libsodium
(~120k), which is much higher than the additional size of nslookup in
BusyBox (which is essentially just a bunch of calls to stuff which is
already in the libc). Adding the functionality in BusyBox nslookup
will increase the size of BusyBox somewhat, but not nearly by that
much. If needed, I can write this.
What do you think?
I think adding this functionality to BusyBox will be far cheaper in
terms of size used. Since for many people the [SERVER] argument is not
going to be used anyway, so switching to hostip by default seems
overkill. For the time being, people that need this functionality
should either use a modified /etc/resolv.conf (if possible) or use
bind-host instead.
