;; Got bad packet: bad compression pointer
109 bytes

whereas at my desktop it works: | Code: | tfoerste@t44 ~ $ dig -x 139.199.79.28
; <<>> DiG 9.11.0-P5 <<>> -x 139.199.79.28
;; global options: +cmd
;; Got answer:

And now - a minute later - I get at my server | Code: | mr-fox ~ # dig -x 139.199.79.28
;; Truncated, retrying in TCP mode.

Could somebody points me to an explanation ? TIA
FWIW: At both systems I do use dnsmasq 2.76-r1, have DNSSEC activated and this in resolv.conf :"nameserver 127.0.0.1" and this for dnsmasq: | Code: | mr-fox ~ # grep -v -e '^$' -e '^#' /etc/dnsmasq.conf
domain-needed
conf-file=/usr/share/dnsmasq/trust-anchors.conf
dnssec
dnssec-check-unsigned
server=2a01:4f8:0:a0a1::add:1010
server=2a01:4f8:0:a102::add:9999
server=2a01:4f8:0:a111::add:9898
server=213.133.98.98
server=213.133.99.99
server=213.133.100.100
cache-size=10000 |
Update:dnsmasq related, fixed in 2.77/Update

| What exactly are you expecting? Your "working" desktop does not return anything either: the request for a PTR record simply fails to find anything. Your server probably is NSSEC challenged in some way. |
