Hi,
First: I searched google and google groups for this error message and
everybody said that I have to incrase max recursive clients and that this
message can only appear on large network or with DNS DoS attacks.
Hmm, I have a really small network. Yes, really small, my DNS Server only
serves *1* PC (my own). It is accessible in the whole _private_ LAN and I
cannot believe that anyone from this small network (I know everybody of
the 2 people in my family ;-) is able to do an DoS attack.
It's impossible to reach the DNS server from outside because of NAT and
packet filters and as you can see below, DNS is bound to local interfaces
only.
My big problem is now, that i can only find this error messages in the
/var/log/syslog and nothing more. Also, there are no excessive activities
logged. The first activity logged is from today 7:57 from my own PC.
The last time this happened, I had no time so I just restartet named.
DNS is running as user/group dns chrooted to /home/system/dns.
That's my small config-file:
options {
directory "/";
auth-nxdomain yes; # conform to RFC1035
forwarders {
192.168.200.120; # next servers
192.168.0.1;
};
listen-on port 53 { 127.0.0.1; 192.168.200.121; };
};
(...)
Can anyone explain this?
Thanks
Mark
