All.
There is huge traffic coming out from my DNS server since yesterday and flooding the IP 212.107.121.110, though I have increased the limitation of tcp-clients in named.conf but still the issue. any help would be highly appreciate. My bind version is [root@ns10 ~]# named -v BIND 9.9.2-P1 When checking there are several entries as below. Jul 26 10:53:26 ns10 named[3004]: client 212.107.121.110#4636: no more TCP clients: quota reached quota reached Jul 26 10:53:13 ns10 named[3004]: client 212.107.121.110#4571: no more TCP clients: quota reached Jul 26 10:53:13 ns10 named[3004]: client 212.107.121.110#4572: no more TCP clients: quota reached Jul 26 10:53:19 ns10 named[3004]: client 212.107.121.110#4597: no more TCP clients: quota reached Jul 26 10:53:25 ns10 named[3004]: client 212.107.121.110#4633: no more TCP clients: quota reached Jul 26 10:53:25 ns10 named[3004]: client 212.107.121.110#4635: no more TCP clients: quota reached Jul 26 10:53:26 ns10 named[3004]: client 212.107.121.110#4636: no more TCP clients: quota reached Thanks, Mohammed Ejaz Asst.
