this file. I removed a `pos = 0;' statement from line 552, thinking
that pos is getting initialised in the next statement, but that
stopped dnscache from processing `cname' type records and thus
resolving names. It took me whole day to figure that out.
Anyway...lesson learned. :)
* dnscache.c:
droproot.c:
pickdns.c:
rbldns.c:

in couple of functions as there is already a global variable named
mode.
* readme.ms: changed to reference a web-link wherein DJB put his work
in public-domain. Obviously, the same goes to README.
Mar 3 2009 pjp <pj.pandit@yahoo.co.in>
* This new release is djbdns version 1.05.1. The new build system makes
use of the GNU auto-tools and is fully integrated with the linux
/sbin/service.
* dnscache.c: reads configuration file: PREFIX/etc/ndjbdns/dnscache.conf
PREFIX is the install prefix used by ./configure command.

* Hi, I take this source of original djbdns-1.05, as is, from
http://cr.yp.to/djbdns.html
and aim is to free it from the daemon of `daemontools', make it as
much independent & concise as possible and thus more usable and
maintainable.

refuses to do zone transfers from axfrdns. fix: set aa

portability problem: Linux distributions use bash as /bin/sh;
bash destroys $UID. dorks. impact: dnscache and axfrdns
run as root. fix: envdir, then sh, then envuidgid. but
/bin/sh really has to stop polluting the environment.
20000923
