Hi folks,
Advice needed with nslookup &/or NXDOMAIN please:
I don't know if I've config'd something wrong or maybe found a bug ?
I have 3 servers all running the same named config files,
but with different FreeBSD uname -r versions:
194.221.32.28 flat.berklix.org 5.3-rel
194.221.32.7 tower.berklix.org 4.9-rel
194.221.87.219 thin.berklix.org 4.10-rel
A problem came since I upgraded `flat' to 5.3,
(& now running chrooted with /usr/sbin/named -u bind -t /var/named )
With all 3 servers, runing nslookup on the local server
nslookup
thin.berklix.og
responds normally with the IP,
but though `tower' & `thin' are also OK with non fully qualified name `thin',
running nslookup localy on `flat' now gives errors:
nslookup
thin
Server: 127.0.0.1
Address: 127.0.0.1#53
** server can't find thin: NXDOMAIN
server thin.berklix.org
Default server: thin.berklix.org
Address: 194.221.87.219#53
thin
Server: thin.berklix.org
Address: 194.221.87.219#53
** server can't find thin: NXDOMAIN
On host `flat' a command such as "ping -c 1 thin" works fine.
After upgrading `flat' to 5.3 I ran a `mergemaster -sicv'
so most of my etc files should be OK.
I also tried "mv ~/.[a-zA-Z]* ~/tmp/" to check it wasnt that.
/bin/hostname
flat.berklix.org
/etc/hosts ( on all 3)
127.0.0.1 localhost localhost.berklix.org
/etc/resolv.conf has

NXDOMAIN 3 Some name that ought to exist,
does not exist.
lib/libc/net
getaddrinfo.c res_data.c res_mkupdate.c res_query.c res_update.c
h_errno = HOST_NOT_FOUND;
rclass = C_NONE;
* if (rcode == NXDOMAIN) then the dname does not
* exist and the server is replying out of NCACHE.
* in either case, proceed with the next try
I'm not using IPv6. I've not set up an AAAA rec (dont know what it is).
I dont need an MX rec, despite warning from
http://dnsreport.com/tools/dnsreport.ch?domain=berklix.org
but I guess something is wrong ?
Any ideas please ?
