Hello,
I've installed redhat 5.2 and linuxconf 1.13r8 in a machine with dialup on demand
(diald). In the default configuration, bind8 connects to DNS root servers from a
non-privileged port. Under this condition, ANY dns packet brings the connection up.
It's easily solved putting:
query-source address * port 53;
in the options entry of /etc/named.conf, but whenever I touch dns from linuxconf, this
line goes away :( Maybe Jacques we need a little checkbox somewhere.
And a little question as I have little experience with bind 8: What kind of
misconfiguration can produce such a tcpdump line on the sl0 interface (yes, I know I
should not use 128.1.1.97 in a private lan, but I didn't choose that):
11:04:33.018039 127.0.0.11.53 > 128.9.0.107.53: 19613 A? 128.1.1.97. (28)
The name server is asking for the address of an address (which he IS master of and
corresponds to eth0). I don't have the "loghost" entry in /etc/hosts but I think it's
no longer needed...
TIA
